| polymerase chain reaction detection of enterotoxins genes in coagulase-negative staphylococci isolated from brazilian minas cheese. | for a long time, staphylococcus aureus has been always thought to be the only pathogenic species among staphylococcus, while coagulase-negative staphylococci (cns) were classified as contaminant agents. however, molecular techniques have shown that these microorganisms also possess enterotoxin-encoding genes. the aim of this study was to analyze the frequency of genes for staphylococcal enterotoxins sea, seb, sec, and sed in cns strains isolated from minas soft cheese and to assess the in vitro ... | 2010 | 20528174 |
