No. of bitstreams: 1 Mauro Tavares de Melo.pdf: 976863 bytes, checksum: 9dc2a916f4b14f2e389668fa6353a8bd (MD5) Previous issue date: 2006-03-03 / 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. / A realização deste trabalho, considerando a importância e a natureza pioneira das informações para o Nordeste e a inexistência de registros oficiais de órgãos públicos e privados que se tem acesso em nosso país, teve como objetivo relatar a intercorrência entre tuberculose bovina e caprina em rebanhos leiteiros de Pernambuco e avaliar os fatores de risco relacionados. A identificação de portadores de infecção pelo M. bovis foi realizada pelo Teste Cervical Comparativo (TCC): nos bovinos, de acordo com as diretrizes do PNCEBT; nos caprinos, pelo teste da tuberculina padronizado experimentalmente para caprinos. Foram submetidas ao TCC: 88 vacas com fenótipo predominante da raça Girolanda, com idades entre três a sete anos, criados em dois rebanhos leiteiros e 168 cabras das raças Saanen, Toggenburg e Parda Alpina e seus mestiços, com idades entre dois a seis anos, criadas em seis rebanhos leiteiros localizados em municípios da Mesorregião Metropolitana de Recife, Pernambuco. Conjuntamente, a freqüência de vacas e cabras que reagiram positivamente ao teste da tuberculina foi de 10,9%, destacando-se taxas elevadas nos caprinos (16,2%) e nos bovinos (19,4%). As vacas e cabras que manifestaram reações imunoalérgicas clinicamente inconclusivas às tuberculinas corresponderam a 8% e 1,2%, respectivamente. Conjuntamente, as freqüências de vacas e cabras positivas e inconclusivas formaram o índice de 14,4%. Das vacas submetidas ao TCC, 17,0% (15/88) reagiram positivamente. Em valores médios, as positivas apresentaram reações imunoalérgicas às tuberculinas bovina e aviária com intensidades de 9,4 mm (±3,1) e 3,3 mm (±1,1), respectivamente, sendo a diferença entre as duas de 6,0 mm (± 1,8). Das cabras submetidas ao TCC, 7,7% (13/168) reagiram positivamente. Em valores médios, as positivas apresentaram reações imunoalérgicas às tuberculinas bovina e aviária com intensidades de 14,1 (± 6,2) e 6,4 mm (±4,2), respectivamente, sendo a diferença entre as duas de 7,7mm (± 3,4). As evidências clínico-epidemiológicas observadas neste estudo, além de demonstrarem que a tuberculose encontra-se amplamente disseminada nos rebanhos examinados, sugerem que a infecção pelo M. bovis em caprinos pode ocorrer em conexão com a infecção em bovinos, a partir da grande circulação de leite de vaca entre rebanhos caprinos cujos produtores adquiriram a prática comum da utilização do leite de vacas para cabritos como medida preventiva contra a CAE.
