Infections with the intestinal protozoan parasite Giardia in dogs and cats are common. Clinical signs vary from asymptomatic to small bowel diarrhea and associated discomfort. The control of infections in dogs is frequently a frustrating issue for animal owners and veterinarians. Drugs with antiprotozoal activity such as fenbendazole and metronidazole are recommended, however, they do not show 100% efficacy and superinfections occur regularly. Ronidazole is currently the drug of choice for the treatment of Tritrichomonas foetus in cats and there is now limited information available about its efficacy against Giardia spp. In the kennel investigated, dogs regularly showed loose feces and the presence of Giardia (assemblage C, renamed as G. canis) cysts. An elimination strategy of this parasite involving strict hygiene management and disinfection of the enclosures with 4-chlorine-M-cresol, oral treatment with ronidazole (30-50mg/kg BW bid for 7 days) and two shampooings (containing chlorhexidine) at the beginning and the end of the treatments was implemented for a group of 6 dogs. As a control another group of 7 dogs was transferred to the disinfected enclosures and shampooed, but left untreated. Dog feces were tested for the presence of Giardia cysts (SAF concentration technique) or Giardia antigen with a commercial ELISA (NOVITEC(?)) and a quick immunochromatography-based test (SensPERT(?)) before and between 5 and 40 days after the last treatment. All ronidazole-treated dogs were negative for Giardia cysts and antigen up to 26 days after the last treatment, while between 1 and 5 of the control animals tested positive in each of the test series. At this point, also dogs of the control group were again moved into clean enclosures, shampooed twice and treated with ronidazole. Five, 12 and 19 days after the last treatment, the dogs in the control group tested negative for Giardia cysts and antigen. However, all animals had again positive results at later time points in at least one of the three applied diagnostic techniques within 33-61 days after treatment. Furthermore, all dogs had episodes of diarrhea (for 1-4 days) within 14-31 days after treatment and unformed feces during the whole experiment. The positive effect of ronidazole against Giardia infections in dogs could be confirmed in this study. In particular, the combination of ronidazole treatment combined with the disinfection of the environment and shampooing of the dogs was highly effective in reducing Giardia cyst excretion and may therefore constitute an alternative control strategy for canine giardiosis. 相似文献

OBJECTIVE: To determine efficacy of treatment with a combination febantel-praziquantel-pyrantel product, with or without vaccination with a commercial Giardia vaccine, in dogs with naturally occurring giardiasis. DESIGN: Prospective trial. ANIMALS: 16 Beagles naturally infected with Giardia duodenalis. PROCEDURES: During phase 1, 6 dogs were treated with the parasiticide for 3 days (4 were also vaccinated). Four weeks later, all 6 dogs were treated with the parasiticide again for 5 days and were bathed and moved to clean cages after the last treatment (phase 2). Nine dogs were treated with the parasiticide for 3 (n = 4) or 5 (5) days and bathed and moved to clean cages after the last treatment (phase 3). Fecal samples were collected twice weekly for 24 days after treatment and tested for cysts with a quantitative zinc sulfate flotation technique and for Giardia antigen with an immunoassay. RESULTS: Dogs in phase 1 were all shedding cysts again by day 24. In phase 2, only 1 dog shed cysts after treatment, and shedding was transient (day 17). In phase 3, neither cysts nor antigen was detected in fecal samples from 2 of 4 dogs treated for 3 days and 4 of 5 dogs treated for 5 days. In 18 of 57 (31.6%) fecal samples, cysts were seen, but results of the immunoassay were negative. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that when a combination febantel-praziquantel-pyrantel product is used to treat dogs with giardiasis, bathing and changing the environment after treatment may be more important in preventing recurrence than duration of treatment. 相似文献

Giardiasis in a cattery 总被引：1，自引：0，他引：1
C E Kirkpatrick J P Laczak 《Journal of the American Veterinary Medical Association》1985,187(2):161-162
Giardia sp infection was believed responsible for chronic, intermittent diarrhea in a group of 14 Persian cats. Seven of the cats were shedding Giardia sp cysts, and 6 of these cats had diarrhea at the time of fecal examination. Conversely, only 1 of 6 clinically normal cats in the group was shedding Giardia sp cysts. Cysts were not detected in feces of 2 cats with diarrhea. Cats less than or equal to 3 years old were more likely to be found shedding cysts. The parasite apparently was eradicated from the cattery by a combination of cage disinfection (1% sodium hypochlorite solution) and oral furazolidone treatment (4 mg/kg of body weight, BID for 5 consecutive days). During treatment, clinical signs resolved, and all cats remained clinically normal 2 months after treatment. 相似文献

OBJECTIVE: To determine whether fenbendazole effectively eliminates Giardia organisms from chronically infected cats that have a concurrent Cryptosporidium parvum infection. ANIMALS: 16 clinically normal cats. PROCEDURE: Eight cats with chronic concurrent Giardia and C parvum infections received fenbendazole (50 mg/kg, PO, q 24 h) for 5 days (treatment-group cats). Feces from each cat were collected and processed 3 days weekly for 23 days after treatment. By use of an immunofluorescent assay for detection of Giardia lamblia cysts and C parvum oocysts, organism numbers were counted and scored. Fecal results from treatment-group cats were compared with those of 8 untreated cats with Giardia infection but no C parvum infection (control-group cats). RESULTS: Four of 8 treatment-group cats had consistently negative results for Giardia infection after treatment. These 4 cats had consistently positive results for C parvum oocysts prior to treatment and consistently negative results after treatment. One treatment-group cat had positive results for cysts on all fecal samples, and 3 treatment-group cats had 1 to 3 negative results and then resumed shedding large numbers of cysts; each of these cats had consistently positive results for C parvum oocysts. When compared with control-group cats, treatment-group cats shed less Giardia cysts during week 1 after treatment but not during week 2. CONCLUSIONS AND CLINICAL RELEVANCE: Administration of fenbendazole decreases Giardia cyst shedding to less than detectable numbers in some cats. In our study, persistent C parvum infection may have been associated with failure of fenbendazole to eliminate Giardia infection. 相似文献

Intestinal parasites have been anecdotally associated with pruritus in dogs. A relationship was proposed when the elimination of a specific parasite resolved the pruritus, and re-infection with a parasite caused the pruritus to recur. Ascarids, coccidia, hookworms, tapeworms and whipworms have all been incriminated. Recent reports in the human and veterinary literature have suggested that there may be a relationship between Giardia infection and the development of pruritus and other allergic signs. In order to determine if there is an association between infection with Giardia and pruritus in dogs, faecal samples were collected from 71 pruritic dogs and 101 clinically normal dogs. Three faecal samples from each animal were analysed using a zinc-sulphate concentration technique for the presence of Giardia cysts, and one randomly selected faecal sample from each dog was analysed with an ELISA for Giardia -specific antigen. Ten of 101 dogs (9.9%) in the clinically normal group tested positive with the ELISA, and Giardia cysts were detected in the faeces of seven of these antigen-positive dogs. No Giardia cysts were found in the dogs that tested negative with the ELISA. None of the dogs in the pruritic group tested positive for Giardia by either method. The results indicated a negative association between Giardia infection and pruritic skin disease ( P = 0.006). Cephalexin was commonly used in the pruritic group, but not in the control group, and may therefore be an explanatory variable.

There are several drugs available for the treatment of giardiasis in cats, including metronidazole. The purpose of this study was to determine whether metronidazole benzoate administered at a dose of 25 mg/kg, orally, twice a day for 7 days lessens or eliminates Giardia cyst shedding in cats with chronic infection. Twenty-six, adult, laboratory-reared cats were used in this study. Sixteen cats had been inoculated orally with cysts of a human Giardia sp. isolate and had completed a Giardia vaccine study in one animal holding room. The other ten cats were infected with the same Giardia sp. presumably by contamination from the adjacent room where the Giardia vaccine study cats were located. From each cat, a fecal sample was collected within 1 week of the start of treatment and then every 2 to 4 days for 15 days after treatment was completed. Fecal samples were analyzed for the presence of Giardia cysts using a commercially available direct immunofluorescence test (IFA). Clinical signs of drug toxicity were not detected during the study. 相似文献

Feces were collected from 107 asymptomatic dogs at a research facility in Guelph, Ontario. The prevalence of Giardia infection was 11% (12/107). To assess the effectiveness of Giardia vaccination for treatment of Giardia carriage, 9 additional asymptomatic Giardia antigen-positive dogs were brought into the facility. The Giardia antigen-positive dogs were then randomly allocated to receive either vaccine (n = 10) or a saline placebo (n = 10). Feces were then monitored monthly for 6 mo for Giardia antigen and Giardia cysts. At weeks 4, 8, 12, and 16 following vaccination, there were more Giardia-positive dogs in the vaccinated group (10/10, 9/10, 9/10, 8/10, respectively) compared with the controls (7/10, 7/10, 8/10, 4/10, respectively). At week 20, an equal number of dogs (5/10) were Giardia positive, and at week 24, fewer dogs were positive in the vaccinated group than in the control group (2/10 versus 5/10, respectively). However, there was no significant difference between the 2 groups. Vaccination was, therefore, not an effective treatment for asymptomatic canine Giardia infections in this setting. 相似文献

This study evaluated the effect of two combination products containing febantel, pyrantel, and praziquantel (FPP) for the treatment of Giardia species in experimentally infected kittens. In experiment 1, five kittens were administered the United States (US) formulation of FPP at doses of 37.8 mg/kg, 7.56 mg/kg, and 7.56 mg/kg, respectively, PO, q24h, for 5 days and four kittens remained as controls. In experiment 2, five kittens were administered the European formulation of FPP at the doses of 12.5 mg/kg, 12 mg/kg, and 4.16 mg/kg, respectively, PO, q24h, for 5 days and four kittens remained as controls. In experiment 3, six kittens were administered the US formulation of FPP at 56.5 mg/kg, 11.3 mg/kg, 11.3 mg/kg, respectively, PO, q24h, for 5 days and five kittens remained as controls. Thirteen days after treatment, kittens testing negative for Giardia species cysts were administered 20 mg/kg methylprednisolone acetate, IM, weekly for a maximum of two injections. Feces were analyzed for Giardia species cysts using a direct immunofluorescence test. After experiment 3, four of the six treated kittens, but no control kittens, remained negative for Giardia species after the administration of methylprednisolone acetate. 相似文献

9 Giardia-free calves were artificially infected with 1.5-5.1 x 10(6) Giardia cysts originating from Swiss cattle ("bovine isolates"). In 4 of these animals the course of infection was examined. After prepatent periods of 7-8 days all calves excreted high numbers of Giardia cysts for 60-112 days. During patency on 44% of the examination days Giardia cysts and antigen could be detected simultaneously in faecal samples using the flotation method and a sandwich-ELISA, respectively. With the exception of light diarrhoea lasting only for some days at the beginning of patency no other symptoms occurred. Further 5 artificially infected calves were submitted to autopsy. Giardia trophozoites were detected in 4 calves in the jejunum and in 1 animal in the ileum (peroxidase-antiperoxidase method). All animals were simultaneously infected with Campylobacter spp. and/or Rota- and Corona-virus. Electronmicroscopically mucosal attachment sites of Giardia trophozoites had intact microvilli and enterocytes. In various parts of the intestine blunting and flattening of the villi and cellular infiltrations of the mucosa were present. These alterations in calves are generally associated with bacterial and/or viral infections of calves. A Swiss bovine Giardia cyst-isolate was transmitted to 4 Giardia-free conventionally maintained lambs which excreted Giardia cysts after prepatent periods of 10-21 days for 31-61 days. 相似文献

The purpose of this study was to determine the sensitivity of dogs with hyperadrenocorticism to treatment with the adrenocorticolytic agent mitotane. Specifically, we looked for differences in response to treatment using this drug in dogs with adrenocortical tumors (adrenal tumor hyperadrenocorticism, ATH) vs those with pituitary-dependent hyperadrenocorticism (PDH). For inclusion in this study, each dog must have had clinical signs, data base laboratory abnormalities, and endocrine screening test results consistent with the diagnosis of hyperadrenocorticism. Further, each dog had to have been treated for at least 6 months with mitotane and have histologic evidence for adrenocortical or pituitary neoplasia (all dogs were necropsied). Thirteen dogs with ATH (8 carcinomas, 5 adenomas) were identified. The ages and body weights of these 13 dogs were computer-matched to 13 dogs with PDH. All dogs were initially treated with approximately 50 mg of mitotane/kg/d of body weight. Reexaminations were performed after 7, 30, 90, and 180 days of treatment. Individual dosages varied widely after the initial 5 to 12 days of treatment. The mean (+/- SD) dose of mitotane (mg/kg/d) for the first 7 days of treatment was 47.5 +/- 9.4 for dogs with ATH vs 45.7 +/- 11.9 for dogs with PDH. The mean plasma cortisol concentrations 1 hour after ACTH administration at the 7-day recheck were significantly higher in dogs with ATH (502 +/- 386 nmol/L) than in dogs with PDH (88 +/- 94 nmol/L).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The protozoan Giardia duodenalis is a mammalian-infecting parasite that produces diarrhoea and malabsorption in its hosts. A survey to investigate canine infections with G. duodenalis in Romania was undertaken between June 2008 and December 2009. The objectives of the study were to (i) estimate the prevalence of infection in different dog populations (kennels, shelters, shepherd, household) using microscopy and a commercially available enzyme-linked immunosorbent assay (ELISA) test kit; (ii) to establish the level of agreement and characteristics of the tests; and (iii) to identify risk factors for infection by multivariate logistic regression models. Faecal samples were collected from 614 dogs aged from 1 month to 16 years (mean ± SD=2.88 ± 2.86 years). Each sample was tested for the presence of cysts using a flotation method with saturated sodium chloride solution and 416 out of 614 stool samples were further examined for the presence of G. duodenalis specific antigens using Giardia Microwell ELISA (SafePath? Laboratories). Giardia cysts were identified in 8.5% of total dogs (52/614) and statistical significantly more frequently in dogs living in communities. The cysts prevalence according with dog populations was as follows: 7.2%(9/125) in kennel dogs; 16.5%(27/164 in shelter dogs; 4.3%(2/46) in shepherd dogs; 4.8%(4/84) in household dogs from urban areas; and 5.1%(10/195) in household dogs from rural areas. The overall prevalence of Giardia infection by ELISA was 34.6% (144/416). The prevalence was significantly higher in kennel dogs (50%; 13/26), shelter dogs (47.7%; 74/155) and shepherd dogs (40.5%; 17/42) than in household dogs from urban areas (34.1%; 15/44) and household dogs from rural areas (16.8%; 25/149). It was noticed poor agreement between microscopy and ELISA (k=0.19). The microscopy performed best, with an Youden Index of 0.74, a Se of 73.68% and a Sp of 100%. ELISA had 100% Sp, but only 19.44% Se. Young dogs (up to 12 months age) and living in communities were identified as risk factors for infection by multivariate logistic regression analysis. 71.2% (37/52) Giardia cysts positive dogs presented co-infections with other intestinal parasites: Toxocara canis (14/52; 26.9%), Isospora ohioensis (12/52; 23.1%), Ancylostoma caninum (9/52; 17.3%), Uncinaria stenocephala (7/52; 13.5%), Trichocephalus vulpis (6/52; 11.5%), Hammondia heydorni/Neospora caninum (5/52; 9.6%), Sarcocystis spp. (5/52; 9.6%), Isospora canis (4/52; 7.7%), Capillaria aerophila (3/52; 5.8%), Strongyloides stercoralis (2/52; 93.8%), Dipylidium caninum (1/52; 1.9%) and Toxascaris leonina (1/52; 1.9%). 相似文献

OBJECTIVE: To determine efficacy of providing drinking water medicated with doxycycline for treatment of spiral bacterial infection in cockatiels. DESIGN: Randomized controlled clinical trial. Animals-18 cockatiels (Nymphicus hollandicus) naturally infected with spiral bacteria. PROCEDURES: Spiral bacterial infection was diagnosed by means of cytologic examination of swab specimens from the choana and oropharynx. Eleven birds (treatment group) were given drinking water to which doxycycline hyclate had been added at a concentration of 400 mg/L for 30 days; the remaining 7 birds (control group) were given unmedicated water. After completion of the study, 6 control birds were treated with drinking water medicated with doxycycline for 21 days. RESULTS: Daily mean plasma doxycycline concentration for birds in the treatment group ranged from 2.26 to 2.86 Mg/mL (overall range, 0.83 to 4.34 Mg/mL). All treated birds were negative for spiral bacteria after treatment for 21 days and remained negative when examined 160 days after treatment ended. Control birds remained positive for spiral bacteria. Control birds treated with doxycycline after completion of the study were negative for spiral bacteria after treatment for 21 days and 30 days after treatment ended. No clinically important adverse effects were associated with treatment. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that providing drinking water to which doxycycline had been added at a concentration of 400 mg/L was effective in eliminating spiral bacterial infections in cockatiels. 相似文献

The excretion of Giardia sp cysts in the feces of naturally and artificially infected cats fluctuated sporadically, and cysts were undetectable several times during 7 weeks of observation. The mean prepatent period for Giardia infection in 7 cats was 9.6 days (range, 5 to 16 days). The amount of the cyst inoculum did not appear to affect the length of the prepatent period. Six of 11 cats had clinical signs consistent with those of giardiasis. Clinical signs and cyst excretion were eliminated after treatment with metronidazole or furazolidone. Moderate oral or parenteral doses of corticosteroids produced little, if any, alteration in the infection. Postmortem examination of 1 inoculated cat revealed Giardia trophozoites in the jejunum and upper portion of the ileum but not in the duodenum, lower portion of the ileum, cecum, or colon. Giardia cysts isolated from cat feces produced infection in Mongolian gerbils but not in C57BL/6J mice. 相似文献

Plasma and skin concentrations of orbifloxacin (Orbax tablets, Schering-Plough Animal Health) were assessed in 14 clinically normal dogs and 14 dogs with pyoderma following oral administration of the drug at 7.5 mg/kg once daily for 5 to 7 days. Skin biopsies and whole blood samples were obtained before dosing and at the time of the expected maximum concentration in skin (3 hours after dosing) on the first and on the fifth to seventh day of dosing. Skin biopsies and plasma were analyzed for orbifloxacin concentrations by high-performance liquid chromatography. Dogs with pyoderma had significantly higher mean skin concentrations of orbifloxacin within 3 hours of administration (Day 0: 7.80 +/- 3.40 mcg/g, Days 4 to 6: 9.47 +/- 6.23 mcg/g) than did dogs with normal skin (Day 0: 3.85 +/- 1.08 mcg/g, Days 4 to 6: 5.43 +/- 1.02 mcg/g). After dosing on Day 0 and after five to seven daily treatments, dogs with pyoderma had significantly higher mean orbifloxacin skin:plasma ratios (1.40 and 1.44, respectively) than did clinically normal dogs (0.81 and 0.96, respectively). The accumulation of orbifloxacin in diseased skin may contribute to the efficacy of this compound for the treatment of bacterial skin infections. 相似文献

The prevalence and infection pattern of naturally acquired giardiasis and cryptosporidiosis in 20 ranch raised beef calves and their dams from birth to weaning was determined. Rectal fecal samples were collected from calves at 3 days of age and weekly thereafter; cows' fecal samples were collected at the time of calving, 1 week later and four times during the summer grazing period. Blood samples were collected from the calves at 3 days of age to determine IgG(1) concentrations. Giardia lamblia cysts were shed by all 20 calves (100%) at some date during the duration of the study. However, only one calf (5%) shed Cryptosporidium parvum on two sample dates during the trial. Giardia cysts were first detected at 3.9+/-1.37 weeks of age with a range of 2-7 weeks of age. The geometric mean number of Giardia cysts in the calf feces increased from none at 1 week of age to a maximum of 2230 cysts/g of feces at 5 weeks of age and then decreased to 2 cysts/g at 25-27 weeks of age. Infection rate of calves shedding Giardia cysts peaked at 85% at 5 weeks of age and then decreased to 21% at 25-27 weeks of age. Giardia cysts, shed by calves peaked 1 week after initial shedding and decreased (P<0.05) for the remainder of the trial with the exception of week 3. There was a lower (P<0.05) percentage of calves shedding Giardia cysts weeks 3-10 and 15-25 compared to when shedding was first detected. All calves had complete or partial transfer of passive immunity as measured by IgG(1) levels. The rate of infection (15%) and the geometric mean number of Giardia cysts in the cows' feces (38.49 cysts/g) numerically increased at 1 week post-calving compared to levels at calving. The rate of infection (40%) numerically increased and the geometric mean number of Cryptosporidium andersoni oocysts in the cow feces (37.48 oocysts/g) increased (P<0.05) at 1 week post-calving and decreased to 0 at 13-16 weeks post-calving. This study is the first to document the cumulative prevalence and infection patterns of Giardia and Cryptosporidium in beef cattle under ranch conditions. 相似文献

OBJECTIVE: To determine the effect of oral melatonin (MT) administration on serum concentrations of sex hormones, prolactin, and thyroxine in dogs. DESIGN: Prospective study. ANIMALS: 8 male and 8 female adult sexually intact dogs. PROCEDURE: 5 male and 5 female dogs were treated with MT (1.0 to 1.3 mg/kg [0.45 to 0.59 mg/lb] of body weight), PO, every 12 hours for 28 days; the other 6 dogs were used as controls. Blood samples were collected on days 0, 14, and 28, and serum concentrations of estradiol-17 beta, progesterone, testosterone, androstenedione, 17-hydroxyprogesterone (17-HP), dihydroepiandrostenedione sulfate (DHEAS), prolactin, and thyroxine were determined. On day 5, serum MT concentrations were measured before and periodically for up to 8 hours after MT administration in 4 treated dogs. RESULTS: Female dogs treated with MT had significant decreases in serum estradiol, testosterone, and DHEAS concentrations between days 0 and 28. Male dogs treated with MT had significant decreases in serum estradiol and 17-HP concentrations between days 0 and 28. Serum MT concentrations increased significantly after MT administration and remained high for at least 8 hours. Prolactin and thyroxine concentrations were unaffected by treatment. CONCLUSIONS AND CLINICAL RELEVANCE: Melatonin is well absorbed following oral administration and may alter serum sex hormone concentrations. 相似文献

Eight dogs with ethylene glycol intoxication were treated with 4-methylpyrazole, an alcohol dehydrogenase inhibitor. Dogs had clinical signs referable to ethylene glycol ingestion including ataxia, depression, vomiting, polyuria, and dehydration. Metabolic abnormalities included high anion gap metabolic acidosis, serum hyperosmolality, isosthenuria, and monohydrate and dihydrate calcium oxalate crystalluria. Serum and urine ethylene glycol concentrations were determined to confirm ingestion of ethylene glycol. A 50-mg/ml solution of 4-methylpyrazole in propylene glycol was administered iv as follows: initial treatment, 20 mg/kg of body weight; at 17 hours after admission, 15 mg/kg; at 25 hours after admission, 5 mg/kg. By 24 hours after admission, all dogs had clinical and metabolic improvement. Of the 8 dogs, 7 were released within 3 days of admission. Four of the 8 dogs returned for follow-up evaluation, at which time biochemical or hematologic abnormalities were not observed. 相似文献

In order to compare natural infection by Cyptosporidium sp. and Giardia sp. in clinically healthy dogs living in two situations (animal shelter and household pets), we conducted 166 faecal exams using the technique of centrifugation-flotation in a sugar-saturated solution. Of the faecal samples, 94 came from shelter dogs and 72 from house pets. Eighty-two (49.4%) contained parasite eggs, cysts or oocysts. Of these, four (2.41%) contained Cryptosporidium sp. oocysts and 52 (31.33%) contained Giardia sp. cysts. There was no statistically significant difference between the origin of the dogs and Cryptosporidium sp. infection. Infection by Cryptosporidium sp. was not associated with the living conditions and sex. With respect to Giardia sp., we observed a statistically significant difference (p < 0.001) between the shelter dogs (45%) and the household pets 12.3%. There was no association of infection by Giardia sp. with age or sex. 相似文献
