Inflammation of the mammary gland, known as mastitis, is still a major problem faced in the Brazilian dairy sector, a situation in which early diagnosis and management are essential to prevent this pathology and to guarantee a quality final product. Production in the metropolitan region of Manaus is still carried out mainly by manual milking, and its characteristics indicate the lack of good practices in the milking process, which can lead to the appearance and spread of infectious mastitis in the properties. Due to these factors, this study aimed to evaluate the microbiological conditions of milk from animals with mastitis produced in the metropolitan region of Manaus. Previously, semiological analyzes of the mammary gland were performed, together with the black-bottom mug test for the detection of clinical mastitis and the California Mastitis Test (CMT) to assess the somatic cell index, 140 teats of 35 animals present were examined. in three selected properties. 98 samples were collected for microbiological analysis, depending on the presentation of changes in the tests. On semiological examination, five animals presented injuries to the udder and breast teats; only one (0,71%) teat of the 140 evaluated in the black-bottom mug test had lumpy milk; in the CMT test, 139 teats were analyzed, with 97 (69,79%) of the teats reacting positively to CCS. Regarding microbiological analysis, these indicated that Staphylococcus spp. was the main agent involved in inflammation of the mammary gland, with 97 (100%), followed by Streptococcus spp., with one (100%) sample and milk from the screen mug test and 64 (65,97%) of the samples reactive to CMT and Enterococcus spp. it was also present in 75 (77,31%). A prevalence of milk with increased CCS and a low index of clinical mastitis was identified in the screen cup test. The presence of the mentioned pathogens characterizes problems of human, vector and environmental contamination of the product, raising serious public health issues. It is expected that this work can collaborate in future research to guide on good practices in milk production in the metropolitan region of Manaus.
