| 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 |
| identification and molecular phylogeny of coagulase-negative staphylococci isolates from minas frescal cheese in southeastern brazil: superantigenic toxin production and antibiotic resistance. | minas frescal is a typical brazilian fresh cheese and one of the most popular dairy products in the country. this white soft, semiskimmed, nonripened cheese with high moisture content is obtained by enzymatic coagulation of cow milk using calf rennet or coagulants, usually in industrial dairy plants, but is also manufactured in small farms. contamination of minas frescal by several staphylococci has been frequently reported. coagulase-negative staphylococci (cns) strains are maybe the most harmf ... | 2016 | 26830747 |
