A juvenile raccoon ( Procyon lotor) was submitted dead to the Minnesota Veterinary Diagnostic Laboratory for rabies testing without history. The animal had marked hypoplasia of the cerebellum. Histology demonstrated that most folia lacked granule cells and had randomly misplaced Purkinje cells. Immunohistochemistry revealed the presence of parvoviral antigen in a few neurons and cell processes. PCR targeting feline and canine parvovirus yielded a positive signal. Sequencing analyses from a fragment of the nonstructural protein 1 ( NS1) gene and a portion of the viral capsid protein 2 ( VP2) gene confirmed the presence of DNA of a recent canine parvovirus variant (CPV-2a–like virus) in the cerebellum. Our study provides evidence that (canine) parvovirus may be associated with cerebellar hypoplasia and dysplasia in raccoons, similar to the disease that occurs naturally and has been reproduced experimentally by feline parvoviral infection of pregnant cats, with subsequent intrauterine or neonatal infections of the offspring.

Point Of Care Tests

Measuring antibodies to evaluate dogs´ immunity against canine parvovirus (CPV) is useful to avoid unnecessary re-vaccinations. The study aimed to evaluate the quality and practicability of four point-of-care (POC) tests for detection of anti-CPV antibodies. The sera of 198 client-owned and 43 specific pathogen-free (SPF) dogs were included; virus neutralization was the reference method. Specificity, sensitivity, positive and negative predictive value (PPV and NPV), and overall accuracy (OA) were calculated. Specificity was considered to be the most important indicator for POC test performance. Differences between specificity and sensitivity of POC tests in the sera of all dogs were determined by McNemar, agreement by Cohen´s kappa. Prevalence of anti-CPV antibodies in all dogs was 80% (192/241); in the subgroup of client-owned dogs, it was 97% (192/198); and in the subgroup of SPF dogs, it was 0% (0/43). FASTest® and CanTiCheck® were easiest to perform. Specificity was highest in the CanTiCheck® (overall dogs, 98%; client-owned dogs, 83%; SPF dogs, 100%) and the TiterCHEK® (overall dogs, 96%; client-owned dogs, 67%; SPF dogs, 100%); no significant differences in specificity were observed between the ImmunoComb®, the TiterCHEK®, and the CanTiCheck®. Sensitivity was highest in the FASTest® (overall dogs, 95%; client-owned dogs, 95%) and the CanTiCheck® (overall dogs, 80%; client-owned dogs, 80%); sensitivity of the FASTest® was significantly higher compared to the one of the other three tests (McNemars p-value in each comparison: <0.001). CanTiCheck® would be the POC test of choice when considering specificity and practicability. However, differences in the number of false positive results between CanTiCheck®, TiterCHEK®, and ImmunoComb® were minimal.

Canine Parvovirus Type 2

Canine parvovirus type 2 (CPV-2) primarily infects dogs, which are the main host reservoir, causing severe gastrointestinal disease associated with immunosuppression. The present study was conducted in Thessaly, Greece and aimed to identify risk and environmental factors associated with CPV-2 infection in diarrheic dogs. Fecal samples were collected from 116 dogs presenting diarrhea and were tested by polymerase chain reaction (PCR) for the presence of CPV-2 DNA. Supplementary data regarding clinical symptoms, individual features, management factors and medical history were also gathered for each animal during clinical evaluation. Sixty-eight diarrheic dogs were found to be positive for the virus DNA in their feces. Statistical analysis revealed that CPV-2 DNA was less likely to be detected in senior dogs, while working dogs, namely hounds and shepherds, had higher odds to be positive for the virus. Livestock density and land uses, specifically the categories of discontinuous urban fabric and of human population density, were identified as significant environmental parameters associated with CPV-2 infection by using Geographical Information System (GIS) together with the Ecological Niche Model (ENM). This is the first description of the environmental variables associated with the presence of CPV-2 DNA in dogs’ feces in Greece.

Different antibody-based tests for rapid detection of Canine parvovirus antigens in feces are commercially available, allowing quick diagnosis in a clinical setting. However, the diagnostic accuracy of these tests compared with standard methods has not been evaluated so far. In the current study, 3 commercial tests were compared with immune-electron microscopy (IEM) and polymerase chain reaction (PCR). Dogs were divided into 3 groups: group A, samples from dogs with acute hemorrhagic diarrhea ( n = 50); group B, dogs with chronic diarrhea ( n = 10); and group C, dogs with no evidence of gastrointestinal disease ( n = 40). Specificity of all 3 commercial tests versus PCR and IEM was good to excellent (92.2–100%). Sensitivity, in contrast, was poor: 15.8–26.3% versus PCR and 50–60% versus IEM. In group A, 10 dogs were positive by IEM and 24 dogs were positive by PCR. Positive PCR results were also obtained from animals in control groups (group B, 1 dog; group C, 5 dogs). No dog in group B or C was positive by IEM. In conclusion, the rapid tests are useful to diagnose canine parvoviral enteritis, but they do not rule out parvovirus infection in an animal with typical clinical signs. In addition, a small percentage of healthy dogs and dogs with chronic diarrhea showed positive PCR results; this may be due to asymptomatic/persistent infection or intestinal passage of virus. The significance of this finding remains unclear.
