Specimens from 181 patients with diarrhoea were examined by a Military General Hospital in a 3-month period during deployment of troops to Saudi Arabia in 1990/1. DNA probes for heat labile (LT) and heat stable (ST) enterotoxin genes identified enterotoxigenie Escherichia coli (ETEC) in 47 of the specimens (26%) and 49 ETEC strains were isolated.
The majority (55%) belonged to a novel ETEC serotype having the O-antigen 159 and a flagellar antigen designated as a provisional new type.
They produced ST and the coli surface associated antigen (CS) 6. Strains of serotype O6 : H16 represented 22% of the ETEC examined.
They produced ST, LT and CS3 with either CS1 or CS2.
The remaining ETEC belonged to seven O : H serotypes.
Overall, ST was the only enterotoxin gene identified in 73% of the ETEC and 67% of the strains expressed CS6 in the absence of other colonization antigens.
Resistance to three or more antibiotics was observed in 53% of the ETEC, including most of the O159 strains.
