Objectives : To investigate risk factors associated with cranial cruciate ligament rupture in dogs. Methods : Retrospective case‐control study: medical records of a first‐opinion veterinary practice were searched for dogs diagnosed with cranial cruciate ligament rupture (1995 to 2007). For each case, six unaffected dogs were randomly selected from all dogs presenting that day for comparison. Multi‐variable binary logistic regression was performed to assess the association of variables on likelihood of cruciate rupture. Results : Frequency of cranial cruciate ligament rupture was 1·19% [95% confidence interval (CI) 1·02 to 1.36%]. West Highland white terriers (n=17), Yorkshire terriers (n=14) and Rottweilers (n=11) were at significantly increased risk of cranial cruciate ligament rupture (P≤0·002). Rottweilers were at five times greater risk compared with other pure breeds (OR 5·12, 95% CI 2·281 to 11·494, P<0·001), obesity quadrupled the risk of cranial cruciate ligament rupture (OR 3·756, 95% CI 1·659 to 8·502, P=0·001) and females were twice as likely to suffer cranial cruciate ligament failure compared to males (OR 2·054, 95% CI 1·467 to 2·877, P<0·001). Dogs less than two years old were statistically less likely to sustain cranial cruciate ligament rupture than dogs older than eight years (OR 0·246, 95% CI 0·127 to 0·477, P<0·001). There was no significant difference in median weights (in kilograms) of neutered dogs, compared to their entire counterparts in either the case group (P=0·994) or in the control group (P=0·630). There was also no significant difference in body condition (‐underweight/normal weight/overweight/obese) of neutered versus entire dogs among the cases (P=0·243), or the controls (P=0·211). Clinical Significance : Cranial cruciate ligament rupture is more likely in Rottweilers and in female dogs, older dogs and obese dogs. Following multi‐variable analysis, it was established that neutering was not associated with increased risk of cranial cruciate ligament rupture.  相似文献

Faecal samples from 183 dogs living in three different shelters in the Rome metropolitan area were randomly collected and examined for the prevalence of giardiosis. Giardia infections were detected by a commercially available ELISA test (ProspecT Giardia Microplate Assay). Overall prevalence was 55.2%. Prevalence rates in single shelters were 74.3, 35.5, and 20.9%, respectively. Using multivariate analysis, no association was found between Giardia-positivity and shelter or sex, breed, or diarrhoea. Giardia-positive dogs were more likely to be younger than 5-year-old (odds ratio [OR] = 2.87; 95% confidence interval [95% CI]: 1.07-7.77; p = 0.038), living together (OR = 2.58; 95% CI: 1.12-5.93; p = 0.026), and fed commercial wet food, both alone and combined with dry food (OR = 5.67; 95% CI: 1.59-20.24; p = 0.008). Correlation between Giardia infection and type of food has not been previously reported in dogs. Possible use of the ELISA test for detection of Giardia infection in dogs and zoonotic implications are discussed.  相似文献

Objectives : To determine the significant risk factors for medial meniscal injury in naturally occurring cranial cruciate ligament rupture and to quantify the risk using multivariate analysis. Methods : A retrospective case control study was performed of dogs that had undergone surgery for cranial cruciate ligament rupture. Data recorded included patient signalment (age, breed and sex), the duration of the lameness, the extent of the cranial cruciate ligament rupture (complete or partial) and the condition of the medial meniscus. Logistic regression was used to analyse the relationship between these variables and tears in the medial meniscus. Results : One hundred and sixty-one of 443 stifles (36·3%) in 366 dogs had a medial meniscal tear. The risk of a medial meniscal tear was increased by 12·9 times in association with complete cranial cruciate ligament rupture (OR 12·9; 95% CI 6·8 to 24·2), by approximately 2·6% for each additional week of lameness (OR 1·026; 95% CI 1·009 to 1·043) and by approximately 1·4% for each additional kilogram of bodyweight (OR 1·014; 95% CI 1·000 to 1·028). Golden retrievers and Rottweilers were at increased risk and West Highland white terriers were at reduced risk of medial meniscal tears compared with Labrador retrievers. Clinical Significance : To minimise the risk of medial meniscal tears, surgical stabilisation should not be unnecessarily delayed.  相似文献

Hypoglycemia is a common complication of virulent canine babesiosis. A study was conducted to determine the prevalence of and potential risk factors for hypoglycemia in canine babesiosis from Babesia canis rossi. Plasma glucose concentration was measured at presentation in 250 dogs with babesiosis, of which 111 were admitted to hospital. The prevalence of hypoglycemia (<60 mg/dL) was 9% (23/250). Twenty-two hypoglycemic dogs required admission, making the prevalence of hypoglycemia in admitted dogs 19.8%. Sixteen dogs had severe hypoglycemia (<40 mg/dL), of which 5 had glucose < 18 mg/dL. Hyperglycemia (>100 mg/dL) was present in 38 dogs, of which 21 were admitted. Risk factors for hypoglycemia identified by univariate analysis were collapsed state (P < .00001), severe anemia (P = .0002), icterus (P = .003), age < 6 months (P = .02), and vomiting (P = .03). After logistic regression analysis, collapsed state (odds ratio [OR] = 18; 95% CI, 1.9-171; P = .01) and young age (OR = 2.8; 95% CI, 0.8-9.7; P = .1) remained significantly associated with hypoglycemia. Toy breeds and pregnant bitches were not at higher risk for hypoglycemia than other dogs. Blood glucose concentration should ideally be measured in all dogs requiring inpatient treatment for babesiosis but is mandatory in collapsed dogs; puppies; and dogs with severe anemia, vomiting, or icterus. Many dogs have probably been misdiagnosed with cerebral babesiosis in the past, and hypoglycemia should be suspected in any dog with coma or other neurological signs.  相似文献

The aim of this study was to determine the prevalence of infection, seroprevalence, and factors associated with antibody response to Ehrlichia canis in dogs of Yucatan, Mexico. The study was carried out in four veterinary clinics located in Merida, the capital city of Yucatan, Mexico. Blood samples were obtained from a total of 120 dogs, and each animal was physically examined to determine age and sex, as well as to record any clinical signs of platelet-related bleeding. Blood samples were analyzed for antibodies to E. canis using an ELISA test, and thrombocyte counts were calculated. Blood smears were prepared to detect typical morulae in leukocytes. The prevalence of infection, seroprevalence and associated factors were calculated. A primary screening was performed using 2 x K contingency tables of exposure variables. All variables with P< or =0.20 were analyzed by a logistic-binomial regression. Fifty-three (44.1%) of the 120 dogs were found to be seropositive to E. canis. In six dogs (5.0%) typical morulae of E. canis were observed in monocytes. These six cases were positive for antibodies and were thrombocytopenic. The following factors associated with seropositive animals were: platelet-related bleeding (Yes: OR=10.26, CI=2.50-42.16, P=0.001), thrombocytopenia (Yes: OR=18.91, CI=4.47-80.03, P=0.000) and age (2-4 years: OR=6.77, CI=1.76-25.97, P=0.005; >4 years: OR=4.24, CI=1.04-17.21, P=0.043).  相似文献

Objectives : The diagnostic utility of routine faecal examinations can be greatly enhanced through an appreciation of risk factors most commonly associated with endoparasitism. Methods : From a sample of 6578 canine patients presenting to a veterinary teaching hospital between 1996 and 2006, this study used univariate and multi‐variable techniques to examine putative signalment, medical history and demographic factors predisposing dogs to intestinal parasites. Results : Age and median household income were the strongest predictors of endoparasitism. The odds of a patient being diagnosed with endoparasites were 0·82 times smaller for every 1 year increase in age (OR=0·82, 95% CI: 0·80 to 0·84) and for every $10,000 increase in median household income, the odds were 0·86 times lower (OR=0·86, 95% CI: 0·83 to 0·89). The variables gender, neuter status, month of diagnosis, admitting clinical service and primary diagnosis were not significant predictors. Animals that were presented for underlying medical conditions were less likely to have parasites and the presence of diarrhoea was associated with 76% lower odds of endoparasitism compared to healthy animals (OR=0·76, 95% CI: 0·64 to 0·90). Clinical Significance : Clinicians should maintain a high index of suspicion for parasites in younger patients that live in high population density and low income neighbourhoods.  相似文献

Objectives : To identify clinical risk factors for seizures in dogs with intracranial neoplasia. Methods : A cross‐sectional retrospective study of 68 dogs with histopathologically confirmed primary or secondary intracranial neoplasia, complete clinical history and magnetic resonance imaging of the brain was conducted. Signalment and clinical history were retrieved from clinical records and magnetic resonance images of the brain were re‐evaluated. Prevalence of findings was compared between dogs with and without seizures. Results : Forty‐two dogs had tumour‐related seizures, the remaining 26 were seizure‐free. Tumour types included meningioma (23 dogs with and 5 without seizures), glioma (9 dogs with and 6 without seizures), choroid plexus tumour (2 dogs without seizures), neuroblastoma (1 dog with seizures) and metastatic/invasive tumours including lymphoma (9 dogs with and 13 without seizures). On the basis of multi‐variable logistic regression analysis, risk factors for seizures associated with intracranial neoplasia were magnetic resonance imaging findings consistent with the presence of neoplastic tissue in frontal lobe [odds ratio (OR) 9·61; 95% confidence interval (CI) 2·59 to 35·61], marked gadolinium enhancement (OR 10·41; 95% CI 2·07 to 52·30) and magnetic resonance imaging findings of subfalcine and/or subtentorial herniation (OR 3·88; 95% CI 1·10 to 13·71). Clinical Significance : Dogs with primary or secondary intracranial neoplasia are at risk of seizures, particularly those with tumours that affect the frontal lobe, enhance markedly with gadolinium, or cause subfalcine and/or subtentorial herniation.  相似文献

We studied risk factors and characteristics of canine transmissible venereal tumours (TVTs) in Grenada. We abstracted data for 38 TVT cases and 114 TVT-free dogs submitted to a veterinary diagnostic laboratory between 2003 and 2006. Occurrence profiles, odds ratios (ORs), and logistic regression models for TVT were determined using a significance level of α = 0.05. TVT was found in 20 (52.6%) female and 18 (47.4%) male dogs. Of the TVT cases, 32 (84.2%) were between 1 and 7 years old, 20 (52.6%) were mixed breeds of dogs, 14 (36.8%) were Grenadian pothounds, while 4 (10.6%) were pure-bred dogs. Characteristic TVT lesions were genital growths [OR = 96.7; 95% CI (27,461), P < 0.001], genital bleeding [OR = 12.7; 95% CI (4.6, 39.2), P < 0.001] and secondary inflammation of TVT lesion [OR = 4.3; 95% CI (2, 10), P < 0.001]. Extragenital TVT lesions were observed in 23% (9/38) of dogs. An increased risk for TVT was associated with age as adult (1–7 years) dogs [OR = 12; 95% CI (1.6, 94), P < 0.001] and status as a Grenadian pothound [OR = 8.6; 95% CI (3, 25), P < 0.001]. Clinicians should educate dog owners about increased risk of TVT for Grenadian pothounds and consider TVT as a possibility for some extragenital tumours.  相似文献

Objective : To review the association between clinical signs and diagnostic findings and the survival time of dogs with dilated cardiomyopathy (DCM), and any influence of treatment prescribed. Methods : A retrospective observational study of 367 dogs with DCM. Survival times until death or euthanasia for cardiac reasons were analysed using the Kaplan–Meier method plus univariate and multivariate Cox proportional hazards models. Two-tailed P values less than 0·05 were considered statistically significant. Results : In the multivariate model, left ventricular diameter (LVDs)-index (P=0·0067), presence of pulmonary oedema on radio-graphy (P=0·043), presence of ventricular premature complexes (VPCs) (P=0·0012), higher plasma creatinine (P=0·0002), lower plasma protein (P=0·029) and great Dane breed (P=0·0003) were negatively associated with survival. Most dogs were treated with angiotensin-converting enzyme inhibitors (93%) or furosemide (86%), and many received digoxin (50%) and/or pimobendan (30%). Thirteen dogs were lost to follow-up. No conclusions could be made in this study on the association between use of drugs and survival. Clinical Significance : The LVDs-index was the single best variable for assessing the prognosis in this group of dogs with DCM. Other variables that were negatively associated with survival were presence of pulmonary oedema on radiography, presence of VPCs, higher plasma creatinine, lower plasma protein and great Dane breed.  相似文献

The medical records of 54 dogs presented to the Hebrew University Veterinary Teaching Hospital and diagnosed with heat stroke were retrospectively reviewed. Data abstracted included history, clinical and clinicopathological signs at admission, treatment, disease progression, and outcome. Exertional and environmental heat stroke were present in 63% (34 of 54) and 37% (20 of 54) of the dogs, respectively, and 78% (42 of 54) were examined between June and August. The mean temperature and heat discomfort index in the particular days of heat stroke were significantly increased (P < .001, P < .001, respectively) compared with their corresponding average daily values. In 27 dogs the body temperature was > or = 41 degrees C (105.8 degrees F). Belgian Malinois (15%, odds ratio [OR] = 24, 95% confidence interval [CI95%] 8.2-64.5), Golden and Labrador Retrievers (21%, OR = 2.08, CI95% 0.95-4.2), and brachycephalic breeds (25%, OR = 1.7, CI95%], 0.81-3.21) were overrepresented, whereas small breeds (<8 kg) were underrepresented (2%, OR = 0.08, CI95%, 0.002-0.48). Thrombocytopenia (45 of 54 dogs) and prolongation of the prothrombin (PT) and activated thromboplastin (aPTT) times (27 of 47 dogs) were recorded during hospitalization. Disseminated intravascular coagulation (P = .013) and acute renal failure (P = .008), diagnosed in 28 of 54 and 18 of 54 of the cases, respectively, were risk factors for death. The overall mortality rate was 50%. Hypoglycemia (<47 mg/dL, P = .003), prolonged PT (>18 seconds, P = .05), and aPTT (>30 sec, P < .001) at admission were associated with death. Serum creatinine >1.5 mg/dL (P = .003) after 24 hours, delayed admission (>90 minutes, P = .032), seizures (P = .02), and obesity (P = .04) were also risk factors for death. Heat stroke in dogs results in serious complications and high fatality rate despite appropriate treatment.  相似文献

The purpose of this retrospective study was to compare home-prepared and chicken hydrolysate diets in the diagnosis of canine adverse food reactions (AFR). Seventy-two dogs were fed home-prepared diets and 109 were fed hydrolysate. Owners chose the type of diet at presentation, and ingredients of home-prepared diets were selected depending on each dog's dietary history. Ectoparasitic infestations and microbial infections were treated during the trials. Cutaneous and gastrointestinal signs and pruritus scores were recorded before starting the diet, 6 weeks into the trials and after provocation with the original diets. AFR was diagnosed if pruritus resolved during the trial and recurred on dietary provocation. The dropout rate was lower for home-prepared diets although not statistically significant (18.1% home prepared; 24.7% hydrolysate, P=0.377). AFR alone was diagnosed in 10 dogs (17%) using home-prepared diets and in 15 (18.3%) fed the hydrolysate. Gastrointestinal problems were more frequent in dogs with AFR than in dogs without AFR (P=0.001). Another 11 dogs (18.6%) in the home-prepared diet group and 20 (24.4%) in the hydrolysate diet group had AFR concurrent with other pruritic diseases, mainly atopy. The similar frequencies of AFR diagnosis in the two groups (P=0.837 AFR; P=0.416 concurrent AFR) indicate that the chicken hydrolysate diet may be a valuable alternative to home-prepared diets in the diagnosis of canine AFR. Prospective cross-over studies are warranted to confirm these findings.  相似文献

Data on age, sex, and breed were obtained from surgical pathologic records of 92 dogs with splenic hemangiosarcoma (SHS) and for 125 dogs with splenic hematoma (SHA) diagnosed in 1985 at the University of Pennsylvania School of Veterinary Medicine. Further information on body weight, clinical and surgical findings, and survival time was obtained for 59 dogs (64.1%) with SHS and 91 dogs (72.8%) with SHA. Splenic hemangiosarcoma was markedly more common in dogs 8 to 13 years old, and SHA was appreciably more common in dogs greater than or equal to 8 years old, compared with dogs 1 to 7 years old. Compared with sexually intact females, only spayed females were at significantly (odds ratio [or], 2.2; 95% confidence interval [CI], 1.2 to 4.1) increased risk for developing SHS; sex predisposition was not found for dogs with SHA. The German Shepherd Dog was the only breed with increased risk for development of either SHS (OR, 4.7; 95% CI, 2.7 to 7.8) or SHA (OR, 2.8; 95% CI, 1.7 to 4.9), compared with all other purebred dogs. Association of tumor type for 7 commonly reported clinical signs with observance of hemoperitoneum at surgery was determined; anorexia (P = 0.01), collapse (P = 0.01), and hemoperitoneum (P less than 0.001) were significantly more common in dogs with SHS. The median survival time for dogs with SHS was 19 days, compared with 338 days for dogs with SHA (P less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

This study aimed to establish the seroprevalence and risk factors associated with neosporosis in sheep and dogs from rural properties. 1497 blood samples were collected from sheep and 42 from dogs that cohabited with sheep from 16 farms located in the central region of S?o Paulo State, Brazil. For the detection of N. caninum antibodies it was performed the indirect fluorescent antibody test (IFAT ≥ 25). For the epidemiological study it was applied a questionnaire for the owners or responsible from the sheep and dogs regarding informations related to neosporosis. The seroprevalence obtained out of the 1497 sheep sera tested was 8.0% (CI95%=6.7-9.2%) and out of the 42 dogs 4.8% (CI95%=0-7.2%). Variables statistically related to seropositivity for N. caninum in sheep were: dams well as water supply (P=0.0004; OR=2.15), presence of other domestic canids (P=0.0013; OR=2.38) and presence of reproductive problems (P=0.0031; OR=1.75).  相似文献

The aim of the present study was to estimate the prevalence of Dirofilaria immitis infection, and to examine the relationship between host factors (gender, age and breed) and D. immitis infection in dogs. The study was designed as a cross-sectional study. A total of 676 dogs were examined for D. immitis infection. Adult worms (necropsy) and blood samples were collected from all animals for diagnosis of D. immitis. Blood samples were examined using a modified Knott's and thick drop techniques. Fifty-six of 676 dogs were diagnosed infected with D. immitis. The odds of infection were 2.85 times higher in female dogs, compared to male dogs (OR = 2.85, 95% CI = 1.5-5.5, P = 0.01). In addition, the odds of infection were 2.11 times higher in > or =3 years old dogs, compared with younger dogs (OR = 2.11, 95% CI = 1.1-4.2, P = 0.03). This information is important for a better understanding of the epidemiology of D. immitis in dogs in Yucatan, Mexico.  相似文献

The aim of the present study was to determine the factors affecting the prevalence of mange-mite infestations in stray dogs of Yucatán, Mexico. The study was carried out in 200 stray dogs of Mérida capital city of Yucatán, Mexico. Four samples (head, thoracic-abdominal area, extremities and ear) were taken from each animal by skin scraping and examined microscopically in 10% KOH solution to detect the presence of mites. Mites were also collected from the external ear canal of dogs using cotton-tipped swabs. The prevalence of different mite species was calculated. A primary screening was performed using 2xK contingency tables of exposure variables. All variables with P< or =0.20 were analyzed by a logistic-binomial regression. The overall prevalence was 34%. Demodex canis (23.0%) was the most frequent mite, followed by Sarcoptes scabei var. canis (7.0%) and Otodectes cynotis (3.5%). The following factors were found: body condition (bad, OR: 5.35, CI 95%: 1.66-17.3; regular, OR: 3.72, CI 95%: 1.39-9.99) and the presence of macroscopic lesions of dermatosis (OR: 42.80, CI 95%: 13.65-134.24).  相似文献

The objective of this study was to determine whether dogs with atherosclerosis are more likely to have concurrent diabetes mellitus, hypothyroidism, or hyperadrenocorticism than dogs that do not have atherosclerosis. A retrospective mortality prevalence case-control study was performed. The study group included 30 dogs with histopathological evidence of atherosclerosis. The control group included 142 dogs with results of a complete postmortem examination, a final postmortem examination diagnosis of neoplasia, and no histopathological evidence of atherosclerosis. Control dogs were frequency matched for age and year in which the postmortem examination was performed. Proportionate changes in the prevalence of diabetes mellitus, hypothyroidism, and hyperadrenocorticism were calculated by exact prevalence odds ratios (POR), 95% confidence intervals (95% CI), and P values. Multiple logistic regression analysis was used to examine the combined effects of prevalence determinants while controlling for age and year of postmortem examination. Dogs with atherosclerosis were over 53 times more likely to have concurrent diabetes mellitus than dogs without atherosclerosis (POR = 53.6; 95% CI, 4.6-627.5; P = .002) and over 51 times more likely to have concurrent hypothyroidism than dogs without atherosclerosis (POR = 51.1; 95% CI, 14.5-180.1; P < .001). Dogs with atherosclerosis were not found to be more likely to have concurrent hyperadrenocorticism than dogs that did not have atherosclerosis (POR = 1.8; 95% CI, 0.2-17.6; P = .59). Diabetes mellitus and hypothyroidism, but not hyperadrenocorticism, are more prevalent in dogs with atherosclerosis compared to dogs without atherosclerosis on postmortem examination.  相似文献

Background: Ehrlichiosis is a multisystemic disease with the potential to cause cardiomyocyte injury in naturally infected dogs.
Hypothesis: Myocardial injury occurs in dogs infected with Ehrlichia canis .
Animals: One-hundred and ninety-four dogs from Brazil with clinical and laboratory abnormalities indicative of ehrlichiosis. Sixteen healthy dogs served as controls.
Methods: Electrocardiogram, echocardiogram, noninvasive blood pressure measurement, and serum cardiac troponin I (cTnI) concentrations were evaluated. Serologic assays and PCR determined the exposure and infection status for E. canis, Anaplasma spp., Babesia canis vogeli, Bartonella spp., Borrelia burgdorferi, Dirofilaria immitis, Ehrlichia chaffeensis, Ehrlichia ewingii, Leishmania chagasi , and spotted-fever group Rickettsia . Dogs were assigned to groups according to PCR status: E. canis infected, infected with other vector-borne organisms, sick dogs lacking PCR evidence for infection, and healthy controls.
Results: E. canis -infected dogs had higher serum cTnI concentrations than controls (median: 0.04 ng/dL; range 0.04–9.12 ng/dL; control median: 0.04 ng/dL; range: 0.04–0.10 ng/dL; P = .012), and acute E. canis infection was associated with myocardial injury (odds ratio [OR]: 2.67, confidence interval [CI] 95%: 1.12–6.40, P = .027). Severity of anemia was correlated with increased risk of cardiomyocyte damage ( r = 0.84, P < .001). Dogs with clinical signs of systemic inflammatory response syndrome (SIRS) were at higher risk for myocardial injury than were other sick dogs (OR: 2.55, CI 95%: 1.31–4.95, P = .005).
Conclusions and Clinical Importance: Acute infection with E. canis is a risk factor for myocardial injury in naturally infected Brazilian dogs. Severity of anemia and SIRS might contribute to the pathophysiology of myocardial damage.  相似文献

Objectives : This study aims to investigate lifestyle risk factors for the development of progesterone‐related diabetes mellitus in female elkhounds. Methods : Owners of 48 diabetic elkhounds and 58 healthy elkhounds were interviewed by phone concerning lifetime diet and exercise routines. A logistic model was developed to assess the impact of diet and exercise on diabetes diagnosis. The agreement between lifetime owner‐perceived body condition score (BCS) and veterinary‐perceived BCS at inclusion was estimated in healthy control dogs using the Kappa statistic. Results : The model showed that diabetic dogs had increased odds for having been overweight (before diagnosis) compared with controls (OR=2·8, 95% confidence interval 1·1–7·5, P=0·034). Although feeding other food than commercial dog feed was associated with diabetes case status, the effect was not significant after BCS was entered into the model. The overall agreement between lifetime owner‐ and veterinary‐perceived BCS at inclusion in the study was 75% and had a Kappa statistic of 0·16 (P=0·12). Clinical Significance : This study indicates that a high owner‐perceived lifetime BCS is associated with progesterone‐related diabetes in elkhounds.  相似文献

The present study conducts a serological survey on the presence of canine dirofilariosis in domestic dogs using an enzyme-linked immunosorbent assay (ELISA) kit. A total of 310 household dogs (166 females and 144 males) in Chongqing, Kunming, Nanchang, Fuzhou, Guangzhou, Shenzhen, and Nanning in Southern China were examined. Of the 310 dogs, 42 (13.5%) were seropositive for dirofilariosis. No statistically significant difference was observed in terms of sex in the seroprevalence of dirofilariosis using the ELISA kit. The positive rates for dirofilariosis were 6.6% in the 0-1-year-old group, 13.8% in the 1-4-year-old group, and 21.6% in the less than 4-year-old group. The statistical analysis revealed that significant differences were observed in the 1-4-year-old group (P=0.037, OR=0.441, 95% CI=0.170-1.144) and less than 4-year-old group (P<0.001, OR=0.256, 95% CI=0.095-0.693). In the regional comparison, the shoreline city Shenzhen (18.8%) had a significantly higher prevalence than urban and mountain areas (P<0.05, OR=0.310, 95% CI=0.066-1.445). In conclusion, Dirofilaria immitis infection in domestic dogs was present in Chongqing, Kunming, Nanchang, Fuzhou, Guangzhou, Shenzhen, and Nanning. Therefore, heartworm treatment and/or chemoprophylaxis for the captured domestic dogs are necessary in these areas. To the best of our knowledge, the present study is the first using serological methods to examine D. immitis infection in domestic dogs in Mainland China in the recent years.  相似文献

Objective : To investigate the relationship between endocrinopathies and diagnosis of gall bladder mucocele in dogs via a retrospective case‐control study. Methods : Records of 78 dogs with a surgical or ultrasonographic diagnosis of gall bladder mucocele were examined for the presence or absence of hyperadrenocorticism, hypothyroidism and diabetes mellitus. Two age‐ and breed‐matched controls for each gall bladder mucocele dog (156 total control dogs) were examined for the same concurrent diseases. A matched case‐control analysis was performed using conditional logistic regression. Results : The odds of mucocele in dogs with hyperadrenocorticism were 29 times that of dogs without hyperadrenocorticism (P=0·001; 95 per cent CI 3·8, 219·9). No difference was found between dogs with and without diabetes mellitus. Although a significant association was found between gall bladder mucocele and hypothyroidism, potential observation bias was also identifi ed. Clinical Significance : Hyperadrenocorticoid dogs that were presented for acute illness with laboratory evidence of hepatobiliary disease should undergo evaluation for the presence of a biliary mucocele. Dogs diagnosed with a gall bladder mucocele should be screened for concurrent hyperadrenocorticism if clinical suspicion exists.  相似文献
