    ..21+/-0.50 to 1.23+/-0.89 log CFU/g and from 1.33+/-0.58 to 2.78+/-0.43 log CFU/g, respectively. The results showed that faecal contamination still needs to be reduced, especially in specific individual plants. ..

    ..BlaB could be acylated by some of them, and it can therefore be considered as a penicillin-binding protein. BlaB is devoid of beta-lactamase, D-aminopeptidase, DD-carboxypeptidase or thiolesterase activity. ..
