Isolation of Yersinia enterocolitica from well water and growth in distilled water. 1977

A K Highsmith, and J C Feeley, and P Skaliy, and J G Wells, and B T Wood

Yersinia enterocolitica was recovered from well water during a large water-borne outbreak of gastrointestinal illness. Isolates were predominantly Nilehn biotype 1, of which 57% were serologically nontypable. Isolation and enumeration of these Y. enterocolitica strains were made on M-Endo broth. Laboratory studies were conducted on selected isolates to establish the growth of Y. enterocolitica in distilled water and the competitive growth of this organism in various enteric media. Growth was obtained in sterile distilled water without added nutrients at 4, 25, and 37 degrees C. M-Endo medium gave equal or better recovery of Y. enterocolitica in competitive growth studies than did other commonly used enteric media using the membrane filter technique and incubating at 35 degrees C. All well water isolates were confirmed biochemically at 25 and 35 degrees C and serotyped, and antibiotic susceptibility tests were performed.

UI	MeSH Term	Description	Entries
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
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
