RELATÓRIO DE ESTÁGIO CURRICULAR SUPERVISIONADO (PRODUÇÃO E SANIDADE DE SUÍNOS): LESÕES PULMONARES E AGENTES

Abstract

This study aimed to describe the frequency of pulmonary lesions and the bacterial agents isolated from pigs slaughtered under Federal Inspection Service in southwestern Goiás. An observational, descriptive, and documentary study was conducted using post-mortem inspection data obtained from April 30 to May 21, 2026, together with laboratory results from samples selected during routine inspection. Daily percentages of pleuritis ranged from 0.545% to 1.607%. The mean recorded in the system was 1.003% in May and 0.844% in April, a difference of 0.159 percentage points. Laboratory reports recorded the isolation of Pasteurella multocida type A, Actinobacillus suis, and Actinobacillus pleuropneumoniae serotype 8. The findings demonstrate temporal variation in purulent pleuritis records and bacterial diversity among the sampled lesions. However, convenience sampling, repeated tissues from the same animal, and the lack of a complete viral investigation and histopathology preclude prevalence estimates and definitive causal attribution. Slaughterhouse lesion monitoring combined with laboratory diagnosis and herd traceability may support sanitary measures at farms of origin.
