ABSTRACT: This study evaluated palatine tonsils from 327 water buffaloes collected in a slaughterhouse located in the city of Belém, Pará State, Brazil, over four months (nine sample collecting visits). The overwhelming majority (84.71%) of these buffaloes came from Marajó Island, Pará State, Brazil. The main pathological findings were crypt dilatations/keratin cysts (96.0%, 314 cases), mild to moderate follicular lymphoid hyperplasia (93.0%, 304 cases), crypt abscesses (79.8%, 261 cases), tonsillar corpuscles (31.2%, 102 cases) and tuberculoid granulomas (1.53%, 5 cases). Acid-fast bacilli (AFB) were observed in 20% (1 out of 5 cases) of these granulomas. The study indicates that pathological evaluation of tonsils in buffaloes can provide details of structural features of the organ in the species and information on subclinical or asymptomatic tonsillitis.

RESUMO: No presente estudo foram avaliadas tonsilas palatinas de 327 bubalinos, coletadas em nove visitas a um abatedouro frigorífico localizado na cidade de Belém, no estado do Pará, Brasil, em um período de quatro meses. Estes bubalinos, em sua ampla maioria (84,71%), eram procedentes da Ilha de Marajó, no estado do Pará, Brasil. Os principais achados patológicos foram dilatações de criptas/cistos de queratina (96,0%, 314 casos), hiperplasia linfoide folicular leve a moderada (93,0%, 304 casos), abscessos de criptas (79,8%, 261 casos), corpúsculos tonsilares (31,2%, 102 casos) e granulomas tuberculoides (1,53%, 5 casos). Bacilos álcool-ácido resistentes (BAAR) foram observados em 20% (1 de 5 casos) destes granulomas. O estudo indica que a avaliação patológica das tonsilas de bubalinos pode fornecer detalhes de características estruturais do órgão na espécie e informações de tonsilites subclínicas ou assintomáticas.
