Coinfection of the Canine Distemper Virus with Hemoparasites in Dogs from Valledupar: Case Analysis at the QVet Bienestar Animal Laboratory

Background: Canine distemper virus (CDV) causes a viral disease with the same name (canine distemper), with a high rate of contagion, morbidity, and mortality. Meanwhile, Hemoparasites are a group of obligate parasites of blood cells and are pathogens that cause hematological disorders. Coinfections are the main cause of mortality in canines. Signs of apathy and anorexia are related to the presence of hemoparasites. However, the incidence of fever and oculonasal discharges, along with the previously mentioned signs, are associated with canine distemper. Objective: The purpose of this study was to detect CDV and hemoparasites in dogs from the city of Valledupar, Colombia. Methods:194 data points were collected over a period of 13 months from the Laboratorio QVet Bienestar Animal database and processed using buffy coat smear staining for hemoparasite detection and immunochromatography dipstick testing for CDV antigen detection. Result: Data analysis showed that the most prevalent hemoparasite in the 194 samples was Anaplasma sp. (33%), followed by Ehrlichia sp. (16%), and to a lesser extent: Mycoplasma sp. (6%), Babesia sp. 58% of samples were positive for CDV, detected primarily in dogs under 12 months of age. Conclusion: The study conducted in Valledupar, Colombia, demonstrates high susceptibility in puppies to coinfection with CDV and hemoparasites, which increases the risk of complications and mortality. This highlights the importance of accurate diagnosis for proper detection
