No. of bitstreams: 1 IlannaVPMO_DISSERT.pdf: 678162 bytes, checksum: 8003e44133f57aea25bafe46976c4bb5 (MD5) Previous issue date: 2017-02-20 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / 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 / Embora a infertilidade e a perda da prenhez em gatas sejam ainda pouco estudadas, sabe-se que as causas virais se destacam quando referente à esse contexto. Diante disso, este estudo objetivou identificar a prevalência de agentes virais desencadeadores de patologias reprodutivas que culminam com abortamento, natimortalidade e mortalidade neonatal em gatas atendidas no Hospital Veterinário da Universidade Federal Rural do Semi-Árido. Amostras de sangue de 26 fêmeas gestantes foram coletadas para realização de hemograma, bioquímicas renal e hepática e análise da glicemia. Além disso, exame de ultrassonografia foi realizado para avaliação da viabilidade fetal. Quando possível, coletaram-se placentas, humores e tecidos fetais. As amostras sanguíneas foram testadas através de qPCR e foram negativas para os vírus causadores de Leucemia felina (FeLV) e Imunodeficiência felina (FIV). Nos testes qPCR e PCR para presença do Alpha hespervírus felino tipo 1 (FHV-1), apenas uma amostra de sangue materno mostrou-se positiva. Tecidos dos fetos oriundos desta fêmea foram negativos para FHV-1. Todas as amostras maternas foram positivas para Parvovírus felino (FPV) ou canino (CPV) pelos teste qPCR e PCR. Os resultados de hemograma e bioquímica apresentaram significância nos achados de neutrofilia, linfopenia e monocitose, além de aumento discreto das bioquímicas referentes à fígado (ALT e AST). Associando esses achados aos resultados maternos positivos para o Parvovírus (PV) sugere-se este agente como causador dos abortamentos e natimortalidades nas gatas pesquisadas / 2017-05-09
