Testing of canine fecal samples for the presence of parvovirus using real-time PCR, and genetic characterization of the isolates

The Clinical Virology Laboratory at UTCVM is investigating whether current ELISA's detect parvoviruses that may vary antigenically from the prototype CPV-2b, the most common isolate currently circulating in the USA. For this study, we are accepting fecal samples from suspect parvovirus cases (either ELISA negative or ELISA positive samples are acceptable). We will test the sample by real-time PCR, which can detect very low levels of virus in the feces; in addition we will test the sample using IDEXX SNAP CPV ELISA. If positive by the PCR assay, we will then genetically characterize the virus to determine the strain type. If negative by PCR, we will perform electronmicroscopy in order to determine if virus(es) (including heterologous viruses) is/are present.

Study Design:
Prospective, Survey

Sample Size:

Inclusion Criteria:
Dogs with clinical signs compatible with canine parvoviral enteritis.

Exclusion Criteria:
Dogs with diseases other than enteritis compatible with CPV.

Study Controls:
Not applicable

Study Endpoints:
Not applicable

Small amount of fecal sample from animals in acute stage of enteritis; store at 4oC until shipping (refrigeration); place sample in small plastic tube, bottle, or bag; double bag prior to shipping, ship on cold pack.
