Understanding STEC epidemiology and predominance of O157:H-negative in Australia: Genetic characterisation and virulence assessment of STEC isolates
View through CrossRef
This research investigated the epidemiology of Australian Shiga toxin-producing Escherichia coli (STEC). STEC cause mild to severe disease in humans. Australian STEC are non-motile and mis-characterised as O157:H7 that cause severe disease and outbreaks globally. Using comparative genomics, a genetic mutation was found only in Australian STEC. This discovery enables differentiation of Australian STEC from severe disease-causing strains. In addition, Australian STEC strains lack stx2a, unlike international strains. This difference could define why Australian O157 STEC cause mild disease. This research provides an understanding of Australian O157 STEC genetic epidemiology, improving public health responses to outbreaks and surveillance.
