This study was performed considering the public health hazards related to the elimination of mycobacteria through milk of dairy cows suspected or positive for tuberculosis presenting no clinical alterations. A total of 780 milk samples from 52 animals, positive or suspected for tuberculosis, according to Stormont's test, were analysed to detect Mycobacterium spp. The samples consisted of 300 ml/cow, collected in the first milking of the day, during 15 days. Frozen samples were sent to the laboratory, inoculated in Löwenstein-Jensen with reduced glicerol (0.5%) and Stonebrink media and kept under 37ºC for at least 90 days. The genus of each observed colony was initially confirmed by Ziehl-Neelsen and auramin staining methods. The isolation of Mycobacterium... |

Brucellosis is a chronic zoonosis that plays an important role in Public Health. Considering the lack of data in Brazil regarding its presence in raw milk and non-pasteurized dairy products, we determined the presence of brucellae in milk from brucellosis positive animals. The slide agglutination test (SAT), tube agglutination test (TAT) and TAT treated with 2-mercaptoethanol were used to identify positive animals in studied herds. For 3 days, 300 ml milk samples/cow (75 ml/teat) were collected from all productive quarters of the positive animals. These were mixed and centrifuged. Part of the pellet and of the supernatant were inoculated in Farrel and Brodie-Sinton (BS) media supplemented with antimicrobial agents. The inoculated plates and tubes were... |
