Prevalência de lesões sugestivas de brucelose em bovinos abatidos no Estado do Pará, Brasil

Abstract

Brucellosis is an infectious disease caused by bacteria of the genus Brucella, which infect animals and humans, causing serious economic losses, besides raising concerns about public health. Its main manifestations in animals are abortion, premature births, sterility and low milk production. This study aimed to identify the prevalence of lesions suggestive of the occurrence of brucellosis in animals condemned for bovine animals originated from various country of Pará and slaughtered in six establishments registered with the State Inspection Service (SIE). Data were collected by review of reports with records of daily inspections performed by the veterinarian, from the information filed in the State Inspection Service. We studied the data of 295,085 cattle killed, with 56,740 males and 238,345 females in the period January to December 2008. There are a total of 879 cattle condemned for lesions suggestive of brucellosis, where the primary lesion was found the occurrence of cervical bursitis, with a prevalence of 0.3%. Among those diagnosed with bovine brucellosis and convicted, there was a prevalence of 0.35% in females and 0.08% in barrows slaughtered. Thus, there was a predominance in the condemnation of the females (94.65%) compared to males (5.35%). The presence of these lesions suggest that brucellosis in sheep remains widespread in this region, need to establish control and preventive measures included in the National Control and Eradication of brucellosis and tuberculosis (PNECBT) in Para.
