TY - JOUR ID - 788639 AU - Růžičková, Vladislava - Holochová, Pavla - Karpíšková, Renata - Pantůček, Roman - Pospíšilová, Markéta - Doškař, Jiří PY - 2008 TI - Molecular typing of the enterotoxin H-positive Staphylococcus aureus strains isolated from patients and foods in the Czech Republic PB - Transregional Collaborative Research Center 34 CY - Würzburg, Germany KW - Staphylococcus aureus KW - enterotoxin H KW - staphylococcal food poisoning KW - molecular diagnostics UR - http://www.pathostaph.de/ N2 - Staphylococcal enterotoxin H (SEH) is a member of the extracellular mature toxin family, secreted by variety of Staphylococcus aureus strains that were responsible for human disease called Staphylococcal Food Poisoning (SFP). Thirty-two SEH-positive Staphylococcus aureus strains isolated from burned patients and food samples collected in eleven districts of the Czech Republic between 2000 and 2005 were genotypically characterized by detection of the genes for the enterotoxins SEA - SEJ, spa gene polymorphism analysis, pulsed-field gel electrophoresis (PFGE) profiling and ERIC-PCR fingerprinting and prophage carriage. One strain, detected in feta cheese, was implicated in a case of enterotoxinosis. Sixteen of the twenty-eight isolates carried the seh gene alone. The remaining twelve food-derived isolates harbored the seh gene in combination with other enterotoxin genes, most often the seg and sei genes, followed by the sea, seb, sec and sed genes. Four MRSA strains carried the seh and sec and differed from food-derived strains in PFGE, ERIC2-PCR and prophage profiles. Comparison of genomic profiles resulted in the determination of twenty one genotypes designated from G-1 to G-21. Two new, to date not defined, spa types were identified in one strain isolated from raw meat and two strains obtained from prepacked pizza. Our results show that the seh-positive S. aureus isolates from patients and foodstuffs did not originate from a single source or a common ancestor. ER -
