Abstract
S. aureus isolated from diverse transmission sources during the cow milking was studied by amplifying the toxins genes. The milk samples and specimens from teat orifices were collected before milking, and samples from mouthpieces were collected before and during the milking procedure performed at varied climatic conditions. The study on the A to D enterotoxins genes and the toxin of toxic shock syndrome were carried out by amplifying the respective coding sequences. The sea gene showed to be the most prevalent among those analyzed, and the majority of isolated were detected in milk samples from mammary quarters with mastitis. The occurrence of staphylococcal toxins genes in S. aureus isolated from different sources of bovine mastitis epidemiological chain, evidences the feasibility of this microorganism transmission by contaminated milk, being a potential risk to public health.References
