1. A two-year survey of heat-labile that the whole test procedure should be controlled by inclusion of known LT+ETEC strains in each batch of tests. The instructions also implied, wrongly, that various selective media such as MacConkey and enterotoxin-producing Escherichia coli and other enteric pathogens in travellers returning to the Sheffield area;Chapman, P.A.; Mitchelmore, D.L.;Epidemiol Infect,1988
2. Role of heat-labile toxigenic Escherichia coli and reovirus-like agent in diarrhoea xylose lysine desoxycholate agar may be used directly in the assay. LT+ETEC produce little or no toxin when grown on most selective;Echeverria, P.; Blacklow, N.R.; Smith, D.H.
3. Enterotoxigenic Escherichia coli in Sweden;Back, E.; Blomberg, T.; Wadstrom, T.;Infection,1977
4. initial evaluation of the kit no isolates produced Enterotoxigenic Escherichia coli in central Canada;Brunton, J.; Hinde, D.; Langston, C.; Gross, R.J.; Rowe, B.; Gurwith, M.,1980
5. A simplified method for detecting the heat-labile enterotoxin of Escherichia coli;Chapman, P.A.; Swift, D.L.;J Med Microbiol,1984
