Pesquisa de agentes virais causadores de abortamento, natimortalidade e mortalidade neonatal em gatas

Although infertility and pregnancy loss in cats are still little studied, it is known that the viral causes stand out when referring to this context. Aiming at this, this study aimed to identify the prevalence of viral agents that trigger reproductive pathologies that culminate in abortion, stillbirth and neonatal mortality in cats treated at the Veterinary Hospital of the Federal Rural Semi-Arid University. Samples of blood from each mother (26 pregnant females) were collected for hemogram, renal and hepatic biochemistry and blood glucose analysis. Ultrasound examination was performed to evaluate fetal viability. When possible, placentas, humors and fetal tissues were collected. Blood samples were tested by qPCR and were negative for Feline Leukemia (FeLV) and Feline Immunodeficiency (FIV) viruses. In the test qPCR and PCR for the presence of the feline Alpha hespervirus type 1 (FHV-1), only one sample of maternal blood was positive. Tissues from fetuses from this female were negative for FHV-1. All maternal samples were positive by qPCR and PCR for Feline parvovirus (FPV) or canine (CPV). The hemogram and biochemistry results were significant in the findings of neutrophilia, lymphopenia and monocytosis, in addition to the discrete increase in liver biochemistry (ALT and AST). Associating these findings with positive Parvovirus (PV) maternal results suggests this agent as the cause of the abortments and stillbirths in the studied cats
