| Foram comparados os testes de imunodifusão em gel de ágar (IDGA), imunodifusão em gel de ágar em soros tratados pelo 2-mercaptoetanol (IDGA-ME) e reação de fixação de complemento (CFT), aplicados ao diagnóstico da infecção de caninos por Brucella canis. O antígeno utilizado nas técnicas de IDGA e IDGA-ME constituiu-se de lipopolissacarídeos e proteínas de Brucella ovis, amostra Reo 198, e na CFT, o antígeno empregado foi a Brucella ovis, amostra 63/290. Foram examinadas 80 amostras de soro sanguíneo de cães colhidas durante a campanha de vacinação anti-rábica animal do Município de Santana de Parnaíba-SP, realizada em agosto de 1999. As provas sorológicas foram comparadas, duas a duas, pelo teste de Mc Nemar, e a concordância foi analisada pelo indicador... |

| A total of 192 samples of illegal cheese from different regions of the states of São Paulo and Minas Gerais, Brazil, were analyzed for the isolation and detection of Brucella spp. DNA by means of microbiological culture and polymerase chain reaction (PCR), respectively. Samples that yielded positive results were submitted to the analysis of the occurrence of Brucella abortus (biovars 1, 2 e 4), as well as to the differentiation of DNA in B19 vaccinal strain or Brucella abortus field strain using PCR. Although the microorganism was not isolated from any sample, PCR detected 37 positive samples (19.27%) using genus-specific primers. From these, all (100%) were Brucella abortus. Differentiation of the strain showed that 30/37 samples (81.08%) were vaccinal... |

| To determine the presence of Brucella ovis in ovine from Paraíba State, in the Northeast region of Brazil, 80 animals slaughtered in the public slaughterhouse of Patos city were used. Before slaughter, blood samples were collected by jugular venopuncture from each animal, and after slaughter, testicles, epidydimus and uterus were aseptically collected. For the serological diagnosis of B. ovis and B. abortus infections, the agar gel immunodiffusion (AGID) and Rose Bengal (RBT) tests were carried out, respectively. In addition, microbiological culture and polymerase chain reaction (PCR) were performed on testicle, epidydimus and uterus samples. Six animals (7.5%) tested positive for the presence of B. ovis antibodies and all animals tested negative for the... |
