Latex agglutination test for detection of Escherichia coli serotype O157. 1989

Newfoundland and Labrador Public Health Laboratory, St. John's, Canada.

The value of a latex agglutination test (Escherichia coli O157 latex test; Oxoid Ltd.) for rapid presumptive detection of E. coli serotype O157:H7 was determined by laboratory trials and during an outbreak of hemorrhagic colitis. The latex test was found to be a simple, highly efficient and reliable test in detecting E. coli O157:H7 with 100% sensitivity and specificity. It was also found that sorbitol-MacConkey agar cultures were not as useful for food samples as they were for fecal specimens in screening for E. coli O157:H7, but the use of the latex screen was particularly efficient in this setting.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
