No. of bitstreams: 1 Josenaldo Silva Macedo.pdf: 689898 bytes, checksum: 3215e2e1e0646d554d6f16686dd6361d (MD5) Previous issue date: 2011-02-24 / The present work was designed to investigate the incidence of the bacterium Helicobacter spp. In cats from the Recife city, Pernambuco State. The stomach samples were collected from 119 cats, without distinction between race or age, being 56 males and 63 females originated from the Environmental Survey Center (CVA), captured in the city of Recife.. The urease quick test and the histopathological examination using both the Hematoxilin-Eosin (HE) and Giemsa stains were performed. The urease quick test showed that 83,92% of the male (47/56) and 80,95% of the female (51/63) samples were positive for Helicobacter, with a total of 82,35% (98/119) of the population being positive. The Giemsa analysis demonstrated that in 73,21% of the males (41/56) and 74,60% of the females (47/63) samples the Helicobacter spp. Bacteria was found, and the total positive sample in the tested population was 73,94% (88/119). During the analysis performed using the HE stain, was observed that 59,66% (71/119) of the samples showed histopathological alterations, such as: lymphoplasmocitic infiltration with a lymphoid foliculum, microabscess, necrosis, hypotrophy, and in 40,34% of the samples(48/119) no alterations were observed. Since the Helicobacter spp. Microorganisms are able to cause gastric inflammation in cats, having showed , the research studies concerning the clinical importance and elucidate the gastric neoplasic genesis in these animals. It coud conclude that cats originated from Recife city, Pernambuco state, shows high incidence of helicobacteriosis. / O presente trabalho foi delineado para investigar a incidência da bactéria Helicobacter spp. em gatos oriundos da cidade do Recife do estado de Pernambuco. As amostras de estômagos analisadas, foram coletados de 119 gatos sem raça definida e idade, sendo 56 machos e 63 fêmeas provenientes do Centro de Vigilância Ambiental (CVA), capturados na cidade do Recife. Foram realizados para pesquisa de Helicobacter spp., os métodos de teste rápido da urease, o exame histopatológico corado pela técnica hematoxilina-eosina (HE) e pelo método de coloração Giemsa. As análises pelo teste rápido da urease mostraram que em 83,92% das amostras dos machos (47/56) e em 80,95% das amostras das fêmeas (51/63), foi detectada reação positiva para Helicobacter, sendo 82,35% (98/119) na totalidade das amostras. As análises pelo método de coloração pelo Giemsa mostraram que em 73,21% das amostras dos machos (41/56) e em 74,60% das amostras das fêmeas (47/63), foi encontrada a bactéria Helicobacter spp. , sendo 73,94% (88/119) na totalidade das amostras. Na análise das amostras coradas pela técnica de coloração hematoxilia-eosina (HE), verificou-se que em 59,66% das amostras (71/119) apresentaram alterações histopatológicas como: infiltrado linfoplasmocitário com folículo linfóide, microabcesso, necrose, hipotrofia; e em 40,34% das amostras (48/119) não apresentaram alterações histológicas. Dessa forma, os microorganismos do gênero Helicobacter spp. são capazes de gerar inflamação gástrica no gato, sendo necessário cada vez mais aprofundar as pesquisas a respeito da importância clínica e da gênese de neoplasias gástricas nesses animais. Concluiu-se neste trabalho que gatos oriundos da cidade do Recife, estado de Pernambuco apresentam alta incidência de helicobacteriose.
