Resumo: | Samples from 942 cows were tested by the California Mastitis Test – CMT. Most of them were black and white holstein, apparently healthy animals, from 25 dairy farms, located in the State of Goiás, in which milking process was made mechanically. It was found that 375 (39.8%) animals showed positive results to CMT in values ranging from +, ++, +++. Milk from each CMT reactive teat, 667 samples in total, was bacteriologically analised in an attempt to isolate and identify microorganisms associated with intramammarian infections, obtaining 938 strains in pure culture or in association, as follows: Staphylococcus aureus, 291 times (30.2%); Corynebacterium bovis, 120 times (12.5%); coagulase negative Staphylococcus, 112 times (11.6%); Streptococcus agalactiae, 14 times (1.5%); Streptococcus uberis, 36 times (3.7%); Streptococcus pyogenes, 12 times (1.2%); Streptococcus spp, 66 times (6.9%); Pseudomonas spp., 96 times (10.0%); Corynebacterium pyogenes, 24 times (2.5%); Escherichia coli, 60 times (6.2%); Nocardia spp.p. 14 times (1.5%) and others, 93 times (9.6%). These microorganisms were considered as being either primarily pathogens (55.8%) or contaminants (41.6%). KEY-WORDS: Subclinical mastitis; primarily pathogens; contaminant pathogens. |

Foram submetidas ao California Mastitis Test (CMT) 942 vacas, em sua maioria da raça holandesa preta e branca, aparentemente saudáveis, de 25 propriedades leiteiras, que utilizavam ordenhadeira mecânica na obtenção do leite, localizadas no Estado de Goiás. Observou-se que 375 (39,8%) animais apresentaram resultado de +, ++, +++ ao CMT. Os leites de cada teto que reagiram ao CMT, perfazendo um total de 667 amostras, foram analisados bacteriologicamente, visando ao isolamento e à identificação dos microrganismos envolvidos nas infecções intramamárias. Foram isoladas 938 cepas em culturas puras ou em associação: Staphylococcus aureus, 291 (30,2%), Corynebacterium bovis, 120 (12,5%), Staphylococcus coagulase negativa, 112(11,6%), Strepococcus agalactia, 14 (1,5%), Streptococcus uberis, 36 (3,7%), Streptococcus pyogenes, 12 (1,2%), Streptococcus spp., 66 (6,9%), Pseudomonas spp., 96 (10,0%), Corynebacterium pyogenes, 24 (2,5%), Escherichia coli, 60 (6,2%); Nocardia spp., 14 (1,5%) e outros, 93 (9,6%). Esses microrganismos foram categorizados em patógenos contagiosos (55,8%) e em patógenos ambientais (41,6%), apresentando variação estatisticamente significativa.
