Identification and epidemiological description of enterohemorrhagic Escherichia coli O157 strains producing low amounts of Shiga toxin 2 in Aichi Prefecture, Japan.

Abstract excerpt

Out of 68 Escherichia coli O157 field isolates tested in vitro for Shiga toxin (Stx) 2 production, 12 (17.6%) produced no or a limited amount of Stx2 (Stx 2 non- or low-producing strain; TNLP) even though all 68 possessed the stx(2) gene. The remaining 56 were Stx2 high-producing strains. The 12 TNLPs carried the q21 gene allele, which encodes a transcription antiterminator Q protein and is highly homologous to...
