Viral detection in puppies with presumptive diagnosis of canine Parvovirus (CPV)

Abstract

One of the main infectious causes of hemorrhagic gastroenteritis in canines, is Parvovirosis caused by Canine Parvovirus (CPV). This is a disease in Uruguay which affects mainly puppies causing diarrheas that can lead to death of animals within a few days. The main method of diagnosis is the clinical, although there are laboratory techniques such as immunochromatography (IC), hemagglutination (HA), ELISA and PCR for the final diagnosis of the disease. The aim of this work was to confirm the infection in acute cases with presumptive diagnosis of CPV through IC and HA test. A total of 26 fecal samples were analyzed. IC was able to detect 15/26 (58%) and HA detected 16/26 (61,5%). The differences found between the clinic and the laboratory results may be, among other causes, due to the sensibility of the tests used, the time of sampling or a mistaken clinical diagnosis. As it is shown in the results derived from this study, differences between the clinical diagnosis and the IC and HA techniques can be found, therefore interpretation of results should be of concern when the diagnosis of this disease is made.
