Abstract

The objective of this study was to identify the occurrence of genes expressing staphylococcal enterotoxin (sea, seb, sec, and seg) and the toxin gene 1 of toxic shock syndrome (tst) in Staphylococcus aureus coming from cases of bovine mastitis in the state of Pernambuco, Brazil. We analyzed 93 isolates and we observed the presence of toxigenic gene in 20 (21.6%) samples, of which 11 (55.0%) were positive for tst gene, seven (35.0%) for the sec gene, and two (10.0%) for the seg gene. Of the 20 isolates amplified in PCR for the presence of the sec gene, seg and tst, 16 (80.0%) were positive for only one gene and four (20.0%) were positive for two genes (sec and tst). Of the 17 properties from which the samples originated, seven (41.2%) had positive samples for at least one of the genes sec, seg, and tst. This is the first record of the occurrence of the genes encoding the enterotoxin SEC and TST-1 in milk samples from cows with mastitis in the state of Pernambuco, Brazil.
