AbstractFull Text

A total of 53 milk samples from Alagoas, Brazil, were screened for the presence of bacteria [date not given]. It was observed that 60.4% (32/53) of samples analyzed for coagulase positive staphylococci were negative, while 39.6% (21/53) were positive. Values ranged from 4.5×101 CFU/ml to 2.27×106...
