Incidência e aspectos histopatológicos da infecção por Helicobacter spp. em gatos da Cidade de Recife, Pernambuco, Brasil. / Incidence and pathological aspects of infection by Helicobacter spp. in cats from the city of Recife, Pernambuco, Brazil

RESUMO

O presente trabalho objetivou investigar a prevalência da bactéria Helicobacter spp. em gatos da Cidade do Recife, Pernambuco. As amostras de estômagos analisadas foram colhidas de 119 gatos sem raça e idade definida, sendo 56 machos e 63 fêmeas. Para pesquisa de Helicobacter spp., foram realizados os métodos de teste rápido da urease e exames histopatológicos. As análises pelo teste rápido da urease mostraram que em 82,35% das amostras foi detectada reação positiva para Helicobacter. Na análise histopatológica, verificou-se que em 59,66% das amostras (71/119) apresentaram lesões. Essas lesões consistiram em infiltrado linfoplasmocitário com folículo linfoide, microabcessos, necrose, hipotrofia; em 40,34% das amostras (48/119) não foram observadas alterações histológicas. Conclui-se que gatos oriundos da Cidade de Recife, Pernambuco< apresentam alta incidência de infecção por Helicobacter spp. Infiltrado difuso de células linfoplasmocitárias foram as alterações histopatológicas mais frequentes observadas na mucosa gástrica de gatos infectados por Helicobacter spp. (AU)

ABSTRACT

INCIDENCE AND PATHOLOGICAL ASPECTS OF INFECTION BY HELICOBACTER SPP. IN CATS FROM THE CITY OF RECIFE, PERNAMBUCO, BRAZIL. The present study aimed to investigate the incidence of the bacterium Helicobacter spp. in cats from Recife, Pernambuco State, Brazil. Stomach samples were collected from 119 cats, without distinction between race or age, the breakdown by sex being 56 males and 63 females. The urease quick test and histopathological examination using both hematoxilin-eosin (HE) and Giemsa stain were performed. The urease quick test showed positive results for Helicobacter in 82.35% of the samples. The histopathology revealed an alteration in 59.66% (71/119) of the samples, such as lymphoplasmocitic infiltration with a lymphoid foliculum, microabscess, necrosis, and hypotrophy, while in 40.34% of the samples (48/119) no alterations were observed. It was concluded that the cats from the city of Recife, State of Pernambuco, Brazil, presented a high incidence of infection with Helicobacter spp. Diffuse infiltrate of lymphocytes cells was the most frequent histopathological change observed in the gastric mucosa of cats infected with Helicobacter spp. (AU)
