We examined 219 Shiga toxin-producing Escherichia coli (STEC) strains from meat, milk, and cheese samples collected in Germany between 2005 and 2006. All strains were investigated for their serotypes and for genetic variants of Shiga toxins 1 and 2 (Stx1 and Stx2). stx(1) or variant genes were detected in 88 (40.2%) strains and stx(2) and variants in 177(More)
A total of 140 Shiga toxin-producing Escherichia coli (STEC) strains from wildlife meat (deer, wild boar, and hare) isolated in Germany between 1998 and 2006 were characterized with respect to their serotypes and virulence markers associated with human pathogenicity. The strains grouped into 38 serotypes, but eight O groups (21, 146, 128, 113, 22, 88, 6,(More)
OBJECTIVES The objectives of this study were to determine antimicrobial susceptibility and to characterize the molecular mechanisms of multidrug resistance among German food-borne Salmonella isolates of different serovars. METHODS A total of 319 epidemiologically independent multidrug-resistant isolates from German foodstuffs comprising 25 different(More)
The present study was undertaken to identify and characterize integrons and integrated resistance gene cassettes among multidrug resistant (MDR) Salmonella isolates from slaughter animals and food products of animal origin in Ethiopia. A total of 98 epidemiologically unrelated Salmonella isolates comprising 13 serovars were characterized using serotyping,(More)
The presence of integrons in 85 multiresistant German isolates of the predominating Salmonella enterica subsp. enterica serovar Paratyphi B dT(+) clone was investigated. All isolates possessed a chromosomally located Tn7-like class 2 integron carrying the same dfrA1-sat1-aadA1 array of gene cassettes. Only four isolates (4.7%) revealed an additional class 1(More)
Zur Qualitätssicherung wurden vom Nationalen Referenzlabor für Escherichia coli am BfR in den Jahren 2008 und 2009 zwei Ringversuche (RV2008 und RV2009) zum Nachweis und zur Isolierung von Shiga Toxin bildenden Escherichia coli (STEC) aus Hackfleischproben durchgeführt. Am RV2008 beteiligten sich 23, am RV2009 26 Einrichtungen, die sich mit der(More)
In two female patients whose disease had been diagnosed as anorexia nervosa, later examination revealed Crohn's disease. Hence, the frequency of anorexia nervosa signs and symptoms seen in patients with Crohn's disease who had been hospitalised for internistic-psychosomatic treatment, was scrutinised by the authors. Eight out of 25 consecutively treated(More)
The 157-kb conjugative plasmid pEO5 encoding alpha-haemolysin in strains of human enteropathogenic Escherichia coli (EPEC) O26 was investigated for its relationship with EHEC-haemolysin-encoding plasmids of enterohaemorrhagic E. coli (EHEC) O26 and O157 strains. Plasmid pEO5 was found to be compatible with EHEC-virulence plasmids and did not hybridize in(More)
