OBJECTIVE: To characterize the use of antiemetic agents in dogs with canine parvovirus (CPV)-associated enteritis in a veterinary teaching hospital. DESIGN: Retrospective case series. ANIMALS: 77 dogs with CPV-associated enteritis. PROCEDURE: Medical records of 560 dogs with confirmed CPV-associated enteritis that were admitted to a veterinary teaching hospital were reviewed. Exclusion criteria included vaccination against CPV infection within the preceding 2 weeks, hospitalization for < 24 hours or removal from the hospital against advice, or an incomplete record. Signalment, duration of hospitalization, and daily antiemetic administrations were assessed; WBC counts and clinical findings were used to classify dogs as having systemic inflammatory response syndrome (SIRS). RESULTS: 77 dogs were included in the study; 55 (71%) received antiemetics (53 received metoclopramide at least once). Seventy-one dogs survived, and 6 dogs died (all 6 received antiemetics). Compared with dogs that did not receive antiemetics, duration of hospitalization was significantly longer for antiemetic-treated dogs. Daily values of rectal temperature and heart and respiratory rates did not predict administration of antiemetics or duration of hospitalization; however, compared with survivors, SIRS developed more frequently among nonsurvivors. Assessment of emetic events recorded hourly for 17 dogs indicated that antiemetic treatment did not control emesis. CONCLUSIONS AND CLINICAL RELEVANCE: Many dogs with CPV-associated enteritis had persistent vomiting despite antiemetic administration. The apparent difference in duration of hospitalization between antiemetic-treated dogs and other dogs may reflect a difference in disease severity between groups, although antiemetic-associated adverse events (e.g., signs of depression, hypotension, and immune modulation) may prolong hospitalization. 相似文献

From June 1980 through May 1982, 161 pound-source dogs that developed diarrhea while being used in research were evaluated to determine whether canine parvovirus (CPV) type 2 was the etiologic agent. Evaluation included notation of clinical signs, determination of serum CPV-specific immunoglobulin (Ig) M and IgG titers, virus isolation attempts, and histologic examination of tissues. Criteria for diagnosis of canine parvoviral enteritis were serum CPV-specific IgM antibodies, isolation of CPV from feces, and histologic evidence of intestinal crypt cell necrosis. Upon arrival, 67 clinically normal pound-source dogs were evaluated to determine the prevalence of fecal shedding of CPV and to determine their antibody titers to CPV. Parvovirus was not isolated from any of these dogs, although 76% had IgG antibodies and 3% had IgM antibodies. Of the 161 dogs with diarrhea, 40 (25%) had parvoviral enteritis. Of dogs with parvoviral enteritis, 71% had IgG antibodies and 68% had IgM antibodies. Canine parvovirus was isolated from 18 dogs. Serum IgG antibodies were found in 85% of dogs with diarrhea due to other causes. The geometric mean titer of IgG antibodies to CPV was not significantly different among the 3 groups. Clinical signs that appeared significantly (P less than 0.05) more often in dogs with parvoviral enteritis included bloody diarrhea, anorexia, fever (greater than or equal to 39.4 C), and leukopenia (WBC less than 6,000/mm3). Cases occurred throughout the year, without apparent seasonal variation. The duration between arrival and onset of diarrhea was significantly (P less than 0.05) shorter for dogs with parvoviral enteritis.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

OBJECTIVE: To determine whether dogs with naturally occurring canine parvoviral (CPV) enteritis have laboratory evidence of hypercoagulability. DESIGN: Case-control study. Animals-9 dogs with naturally occurring CPV enteritis and 9 age-matched control dogs. PROCEDURE: Blood was collected from all dogs within 24 hours of admission for thromboelastography (TEG) and determination of activated partial thromboplastin time (aP-TT), prothrombin time (PT), antithrombin III (AT) activity, and fibrinogen concentration. Fibrin-fibrinogen degradation product (FDP) concentration, D-dimer concentration, and platelet count were obtained in dogs with CPV enteritis only. Records were reviewed for evidence of thrombosis or phlebitis. RESULTS: All 9 dogs with CPV enteritis had evidence of hypercoagulability, determined on the basis of significantly increased TEG maximum amplitude and decreased AT activity. Fibrinogen concentration was significantly higher in dogs with CPV enteritis than in control dogs. The aPTT was moderately prolonged in dogs with CPV enteritis, and FDP concentration was < 5 mg/ml in 7 of 9 dogs. No dogs had a measurable D-dimer concentration. Platelet counts were within reference range. Four of 9 dogs had clinical evidence of venous thrombosis or phlebitis associated with catheters. One dog had multifocal splenic thrombosis identified at necropsy. CONCLUSIONS AND CLINICAL RELEVANCE: Dogs with CPV enteritis have a high prevalence of clinical thrombosis or phlebitis and laboratory evidence of hypercoagulability without disseminated intravascular coagulopathy. Thromboelastography may help identify hypercoagulable states in dogs. 相似文献

The objectives of this matched case-control study in a veterinary teaching hospital were to investigate the influence of signalment and historical data on the odds of occurrence of canine parvovirus (CPV) enteritis and the potential usefulness of the clinical signs and clinicopathologic abnormalities recorded on admission as prognostic indicators of mean duration of hospitalization (DOH) and outcome of the disease. Ninety-four puppies with natural CPV enteritis and 188 age-matched controls were studied. The odds to develop CPV enteritis were higher in purebreds compared to mixed-breed puppies. Vomiting and depression at the time of admission were associated with a prolongation of DOH by 2 and 1.75 days, respectively. The lymphopenic and hypoalbuminemic dogs were hospitalized for 1.9 and 2.5 more days, respectively, compared to those without these abnormalities. The odds of non-survival were higher in those puppies with evidence of systemic inflammatory response syndrome (SIRS) at the time of admission. 相似文献

We evaluated the ability of an antimicrobial and endotoxin-neutralizing agent, the recombinant amino terminal fragment of bactericidal permeability-increasing protein (rBPI21), to decrease plasma endotoxin concentration and severity of clinical signs of canine parvovirus and to improve survival. This randomized, double-blinded, placebo-controlled clinical trial included 40 client-owned dogs and 9 normal puppies from a closed research colony. Dogs weighing >5 kg (11 lb) with fecal antigen-confirmed parvovirus and clinical signs of vomiting and diarrhea were randomly assigned to receive placebo or rBPI21 infusion over 6 hours. Plasma endotoxin concentration was measured at 0, 3, and 6 hours of infusion. Owners chose continued medical care with either the Veterinary Hospital of the University of Pennsylvania Internal Medicine Service or a local veterinarian. Telephone follow-up was conducted at 14 days. Surviving dogs were reevaluated at >30 days (recovered group), at which time plasma samples for measurement of endotoxin concentration were obtained. Plasma endotoxin concentrations were significantly higher in dogs with parvovirus than in normal or recovered dogs. Despite 90% survival, the rBPI21 treatment did not have a significant effect on outcome, duration of hospitalization, or plasma endotoxin concentrations. Treatment in a tertiary care hospital, however, significantly improved survival but resulted in a significantly increased duration of hospitalization. Endotoxemia occurs in dogs with parvovirus enteritis, but rBPI21 is not associated with improved survival. 相似文献

Objective: To review and summarize current information regarding epidemiology, risk factors, and pathophysiology associated with canine parvoviral infection, and to outline diagnostic and treatment modalities for this disease. Preventative and vaccination strategies will also be discussed, as serologic documentation of immunocompetence and adoption of safe and effective vaccination protocols are crucial in limiting infection and spread of canine parvoviral enteritis. Etiology: Parvoviruses (Parvoviridae) are small, nonenveloped, single‐stranded DNA viruses that replicate in rapidly dividing cells. Canine parvovirus 2 (CPV‐2) remains a significant worldwide canine pathogen and the most common cause of viral enteritis in this species. Diagnosis: Classic presentation of CPV infection includes acute‐onset enteritis, fever, and leukopenia. Definitive diagnostic tests include detection of CPV in the feces of affected dogs, serology, and necropsy with histopathology. Therapy: Standard therapeutic practices for both mildly and severely affected puppies will be discussed. The ability of this virus to incite not only local gastrointestinal injury, but also a significant systemic inflammatory response has recently been reviewed in the literature, and novel innovative experimental and clinical therapeutic strategies, such as antagonism of proinflammatory cytokines and immunostimulation, are introduced in this article. Prognosis: CPV remains a significant worldwide canine pathogen. In experimentally affected dogs, mortality without treatment has been reported as high as 91%. However, with prompt recognition of dogs infected with CPV‐2, and aggressive in‐hospital supportive therapy of severely affected puppies, survival rates may approach 80–95%. 相似文献

Between 18 July 1980 and 2 January 1981, 188 samples (145 faeces and 43 intestinal contents) were submitted from dogs with suspected canine parvovirus (CPV) enteritis. CPV was demonstrated in 56 (30%) of these samples; the weekly rate of positive CPV identification was remarkably constant at approximately 30% even though clinical and often post-mortem findings strongly supported a diagnosis of CPV enteritis. The simplest, most sensitive and most rapid method for detection of virus was haemagglutination (HA) which was twice as sensitive as isolation of virus and 8 times as sensitive as electron microscopy (EM). Forty nine of 56 (88%) samples positive for CPV were from dogs less than 1 year old and 44 (79%) CPV-positive samples were from pups less than 6 months old; only one sample from a pup less than 2 months old (pup was 7 weeks old) was positive. An additional 68 samples (53 faeces and 15 intestinal contents) were submitted from Beagle dogs that were part of a colony of approximately 1200 dogs. Epidemiological data pinpoints the entry of CPV into the colony in November 1978 at which time most dogs including pups less than 6 months of age developed antibody to CPV without developing clinical disease. From these data an overview of some aspects of the pathogenesis and epidemiology of CPV is constructed. 相似文献

A challenge-of-immunity study was conducted to demonstrate immunity in dogs 3 years after their second vaccination with a new multivalent, modified-live vaccine containing canine adenovirus type 2 (CAV-2), canine parvovirus (CPV), and canine distemper virus (CDV). Twenty-three seronegative pups were vaccinated at 7 and 11 weeks of age. Eighteen seronegative pups, randomized into groups of six dogs, served as challenge controls. Dogs were kept in strict isolation for 3 years following the vaccination and then challenged sequentially with virulent canine adenovirus type 1 (CAV-1), CPV, and CDV. For each viral challenge, a separate group of six control dogs was also challenged. Clinical signs of CAV-1, CPV, and CDV infections were prevented in 100% of vaccinated dogs, demonstrating that the multivalent, modified-live test vaccine provided protection against virulent CAV-1, CPV, and CDV challenge in dogs 7 weeks of age or older for a minimum of 3 years following second vaccination. 相似文献

Canine ehrlichiosis and babesiosis have a worldwide distribution with geographic variation in prevalence and main clinical manifestations. We prospectively determined seroprevalence of canine babesiosis and ehrlichiosis, and risk factors for seropositivity. Three hundred and eighty-one dogs were randomly selected to represent the canine population at a Veterinary Teaching Hospital in south Brazil (latitude 23° S). Dogs were tested with a point-of-care ELISA for Ehrlichia canis antibodies and IFA to confirm previous exposure to Babesia vogeli. Multiple logistic regression analysis was then used to estimate adjusted odds ratio (OR) and their 95% confidence intervals. One hundred and thirty-six (36%) dogs were seropositive for B. vogeli antibodies, whereas 87 (23%) dogs were seropositive to E. canis antibodies. Fifty-four (14%) dogs seroreacted to both agents. Adult dogs previously infested with ticks were more likely to seroreact to B. vogeli or E. canis. Superficial bleeding (OR = 12.4) was more common in dogs exposed to B. vogeli, whereas neurological signs (OR = 7.7) were more common in dogs seropositive to E. canis. Neurological signs (OR = 12.0) and lameness (OR = 12.8) were more prevalent in dogs that seroreacted to both organisms. Owners of dogs with ticks were more likely to have been exposed to ticks themselves (OR = 3.2). Canine babesiosis and ehrlichiosis appear to be highly prevalent in this hospital population. Clinical signs differed from the most common signs in other regions with bleeding occurring more in dogs seropositive to babesiosis, but not ehrlichiosis; neurologic signs in dogs with E. canis antibodies; and lameness in dogs that seroreacted to both organisms. 相似文献

Serum antibody titers to canine parvovirus (CPV), canine adenovirus-1 (CAV-1), and canine distemper virus (CDV) were measured in dogs with known immunization status. The dogs represented 3 groups: nonvaccinated dogs less than 12 months old; vaccinated dogs less than 12 months old; and adult dogs greater than 12 months old. For practical reasons, the population from which the specimens were obtained could be considered as free from natural infection with CAV-1 and CDV. In nonvaccinated dogs less than 12 months old, antibodies against all 3 viruses were measured at the time the dogs were given their first vaccination. Altogether, 50.7% of the dogs had titer greater than or equal to 1:10 to CPV, and 26.1 and 46.2% had titer greater than or equal to 1:8 to CAV-1 and CDV, respectively. The concentration of maternal antibody seemed to be of major importance for failure of immunization with use of inactivated CPV vaccine, but not with CAV-1 and CDV vaccination. In dogs less than 12 months old and vaccinated against CPV infection with inactivated virus, only 11.5% had titer greater than or equal to 1:80. In dogs vaccinated against infectious canine hepatitis and canine distemper, 63.2 and 78.3%, respectively, had titer greater than or equal to 1:16. In adult dogs greater than 2 months old and vaccinated against CPV infection, less than 50% had titer greater than or equal to 1:80, regardless of time after vaccination. There was no significant difference in titer between vaccinated and nonvaccinated dogs.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The immune responses in control dogs [1 to 4 years of age, body condition score (BCS): 4 to 5 out of 9] were compared to those of aging dogs (based on breed and body size) either categorized as lean (BCS: 4 to 5 out of 9) or obese (BCS: 8 to 9 out of 9). Of interest were the serum titers to the following common agents found in vaccines, canine parainfluenza virus (CPIV), canine parvovirus (CPV), canine distemper virus (CDV), canine respiratory coronavirus (CRCoV), and Bordetella bronchiseptica. There were no statistical differences in the antibodies to CPIV, B. bronchispetica, and CRCoV, among the age/weight categories, nor among the age/weight categories and the time, in days, between the date of sample collection and the date of the last recorded vaccination for CPIV, B. bronchiseptica, CPV, and CDV. For CPV, the control dogs had significantly (P < 0.002) higher serum neutralization (SN) titers than the lean geriatric dogs and the obese geriatric dogs. For CDV SN titers, the only statistically significant (P = 0.01) difference was that the control dogs had higher SN titers than the lean geriatric dogs. 相似文献

This makes it difficult to identify the patient population most likely to benefit from nutritional support. Five clinically used indicators of nutritional status (serum albumin, hematocrit, hemoglobin, total peripheral lymphocyte count, and a "body condition" score) were evaluated on admission for 105 dogs that wer hospitalized at the Veterinary Hospital of the University of Pennsylvania for serious illness or major surgery. The prognostic relationship between these admission measurements and clinical outcome (discharged vs. died in hospital) was examined. Abnormally low serum albumin, hematocrit, and hemoglobin were associated with poor ultimate clinical outcome (p< 0.01). Hypoalbuminemia has a strong association with protein-calorie malnutrition although serum levels of albumin can be affected by many non-nutritional processes. Admission serum albumin level can predict clinical outcome and may identify a population of critically ill canine patients that could benefit from nutritional support. 相似文献

Antibody titres to canine distemper (CDV), canine parvovirus (CPV) and canine adenovirus (CAV) were measured in 144 adult dogs that had not been vaccinated for between three and 15 years. Protective antibodies to CPV were present in 95 per cent of the population, to CDV in 71.5 per cent and to CAV in 82 per cent. The prevalence of protective titres did not decrease with increasing time interval from the last vaccination for any of the three diseases studied. Booster vaccination increased the dogs CAV titres. For comparative purposes, 199 puppies were sampled at the time of their first and second vaccination. In the case of CPV and CAV a significantly higher proportion of the adult dogs were protected than of the puppies immediately after they were vaccinated. Natural CPV boosting was strongly suspected because the dogs had significantly higher titres three years after their primary vaccination than two weeks after it and three unvaccinated dogs had acquired protective antibody levels uneventfully. There was no evidence of natural exposure to CDV. 相似文献

The emergence of canine parvovirus (CPV) represents a well-documented example highlighting the emergence of a new virus through cross-species transmission. CPV emerged in the mid-1970s as a new pathogen of dogs and has since become endemic in the global dog population. Despite widespread vaccination, CPV has remained a widespread disease of dogs, and new genetic and antigenic variants have arisen and sometimes reached high frequency in certain geographic regions or throughout the world. Here we review our understanding of this emergence event and contrast it to what is known about the emergence of a disease in mink caused by mink enteritis virus (MEV). In addition, we summarize the evolution of CPV over the past 30 years in the global dog population, and describe the epidemiology of contemporary parvovirus infections of dogs and cats. CPV represents a valuable model for understanding disease emergence through cross-species transmission, while MEV provides an interesting comparison. 相似文献

Immunogenic potency of a killed feline panleukopenia virus vaccine against canine parvoviral enteritis in dogs was examined. The vaccine elicited hemagglutination-inhibition antibodies to canine parvovirus (CPV) in all of the 72 dogs which were vaccinated. The vaccine was protective in dogs against both experimentally induced and naturally occurring CPV-induced disease. By statistical analysis, 4 weeks was found to be the optimal spacing between 2 vaccinal doses resulting in hemagglutination-inhibition antibody titers up to 1:5,120. Adverse reactions to the vaccine were not observed. Atypical lymphocytes were found consistently in the CPV-infected control dogs. 相似文献

OBJECTIVE: To determine signalment, clinical features of the disease, and treatment in dogs with diskospondylitis. DESIGN: Case-control study. ANIMALS: 513 dogs with diskospondylitis (cases) and 236,109 canine hospital accessions (controls) from 12 veterinary teaching hospitals. PROCEDURE: Information retrieved from the medical records of 123 dogs with diskospondylitis at the Louisiana State University veterinary teaching hospital between 1980 and 2001 included sex, age, breed, primary complaint, neurologic status, location of lesions, causative organism, treatment, and outcome. The signalment of 390 additional cases from 11 other veterinary teaching hospitals was accessed from the Veterinary Medical Database. Comparisons were made with controls from the same time periods. RESULTS: Male dogs were twice as likely as female dogs to be affected (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.7 to 2.4). Dogs were significantly more likely to be affected as age increased. Purebred dogs, especially Great Danes, were more likely than mixed-breed dogs to be affected (OR, 73; CI, 4.3 to 12.6). For dogs from Louisiana State University, Staphylococcus spp, Brucella spp, Streptococcus spp, and Escherichia coli were isolated most often; multiple organisms were detected via microbial culture in 11 dogs. The mean duration of treatment was 53.7 weeks. CONCLUSIONS AND CLINICAL RELEVANCE: Male dogs, older dogs, and Great Danes appeared more likely to be affected with diskospondylitis than female dogs, dogs < 1 year of age, and mixed-breed dogs, respectively. Long-term administration of antimicrobial drugs for treatment of diskospondylitis may be expected. Identification of the causative organism and early treatment are recommended. 相似文献
