The Escherichia coli K-12 sheA gene encodes a 34-kDa secreted haemolysin.

Molecular microbiology - 1 Jul 1997

del Castillo F J, Leal S C, Moreno F, del Castillo I

Abstract excerpt

Haemolytic toxins belong to one of several classes of virulence factors that contribute to bacterial pathogenicity. The non-pathogenic Escherichia coli K-12 laboratory strain was considered for years to be non-haemolytic. However, overproduction of several transcriptional regulators induced the appearance of a haemolytic activity that is absent under usual laboratory growth conditions. In this work, we have...
