Human infections with enterohemorrhagic E. coli (EHEC) strains of serotype O103:H2 are of increasing importance in Germany. As bovines are the principal EHEC reservoir behind the occurrence of human infections, we analyzed a pathogenicity island (PAI I(RW1374)) of bovine O103:H2 strain RW1374 to identify putative virulence features. This PAI I(RW1374)(More)
We have recently shown that the locus of enterocyte effacement (LEE) of the bovine enterohemorrhagic E. coli RW1374 (O103:H2) resides within a large pathogenicity island (PAI), integrated in the vicinity of the phenylalanine tRNA gene pheV. Here we describe an additional, but LEE-negative genomic island in RW1374 in the vicinity of another phenylalanine(More)
During regular health status monitoring of the colony of amphibian, Mycobacterium (M.) gordonae were isolated from granulomatous lesions of the tiptoes from the South African clawed frog (Xenopus laevis) maintained at the Tierforschungszentrum of the University of Ulm. During a period of three years a total of 21 animals of the colony, consisting of 350-400(More)
Many bacterial virulence attributes, like toxins, adhesins, invasins, iron uptake systems, are encoded within specific regions of the bacterial genome. These in size varying regions are termed pathogenicity islands (PAIs) since they confer pathogenic properties to the respective micro-organism. Per definition PAIs are exclusively found in pathogenic strains(More)
