    Abstract: Enterotoxigenic <I>Staphylococcus aureus</I> is a main cause 
  of Staphylococcal Food Poisoning (SFP). Here, researchers characterized the 
  antimicrobial resistance, distribution and expression of enterotoxin genes of 
  41 Methicillin-Resistant <I>S. aureus</I> (MRSA) isolated from bovine mastitis 
  milk and SFP cases. Apart from three SFP-acquired isolates which could produce 
  extended-spectrum &#946;-lactamases, all the others carried <I>mecA</I> gene 
  and expressed the penicillin-binding protein 2a. The 92.7% of MRSA isolates 
  tested showed twenty two multi-drug resistant patterns among which SFP-acquired 
  isolates had higher resistant rate and the MIC<SUB>50/90</SUB> values of cefotaxime, 
  amikacin, azithromycin, ciprofloxacin and gentamicin than those of milk-acquired 
  isolates. The 95.1% of MRSA isolates carried at least one Staphylococcal Enterotoxins 
  (<I>SEs</I>) gene and could produce the corresponding classical SEs, the differences 
  in the prevalence of enterotoxigenic MRSA observed between milk-acquired and 
  SFP-acquired isolates were not statistically significant. Six SEs genotypes 
  were found, among which the genotypes sea-seg-sei-seln-selm and sea-seb-sec-seg-sei-seln-selm 
  predominated, respectively in milk-acquired and SFP-acquired isolates.
