Resumo: |
The accomplishment of this work, considering the importance and the pioneer nature of the information to the Northeast and the inexistence of official records of public and private agencies that we can have access in our country, had the aim of reporting the rotation between tuberculosis in bovine and in goats in milk flocks in the State of Pernambuco, and to evaluate the related factors of risk. The identification of the M. bovis infected carriers was made through Cervical Comparative Test (CCT): in bovines, according to the lines of direction of PNCEBT; in goats, through the experimentally standardized tuberculin test for goats. Were submitted to the CCT: 88 cows with the predominant phenotype of Girolanda breed, with age between three and seven, raised in two different dairy cattle’s and 168 goats of Saanen, Toggenburg and Parda Alpina breeds and their crossings, with age between two and six, raised in milk flocks located in towns of the Metropolitan Region of Recife, Pernambuco. Jointly, the frequency of cows and female goats that reacted positively to the tuberculin test were 10,9%, standing out the high rates in goats (16,2%) and the bovines (19,4%). The cows and the female goats that had clinical inconclusive hypersensitivity reaction to the tuberculin were 8% and 1,2%, respectively. Jointly, the frequency of cows and female goats that were positive and inconclusive came to the index of 14,4%. The cows that were submitted to the CCT, 17,0% (15/88) reacted positively. On average numbers, the positives showed hypersensitivity reaction to the bovine and avian tuberculin with the intensity of 9,4 mm ( 3,1) e 3,3 mm ( 1,1), respectively, having the difference between the two of 0,6 mm ( 1,8). The female goats that were submitted to the CCT, 7,7% (13/168) reacted positively. On average numbers, the positives showed hypersensitivity reaction to the bovine and avian tuberculin with the intensity of 14,1 ( 6,2) and 6,4 mm ( 4,2), respectively, having the difference between the two of 7,7 mm ( 3,4). The clinical – epidemic evidences observed in this work, not also demonstrates that the tuberculin is highly disseminated on the examined flocks, as well as suggests that the M. bovis infection in goats can occur in connection with the infection in bovines, from the big circulation of cow milk between goat flocks which the producers acquire the common practice of utilizing the cow milk to the baby goats as a preventive measures against CAE. |
