Quantitative determination of Escherichia coli from coliforms and faecal coliforms in sea water. 1992

Public Health Laboratory, Ministry of Health, Tel Aviv, Israel.

Escherichia coli concentration in sea water was determined by the MUG test after primary growth on membrane filters used to determine total coliforms or faecal coliforms. A good correlation (r = 0.86) was found between E. coli obtained from coliforms versus those from faecal coliforms. Verification procedures showed that all the MUG-positive colonies obtained on both media were E. coli. Evaluation of this data and the literature indicated that this technique for estimation of E. coli in sea water is a useful addition to laboratory procedures without generally increasing the time and the expense of the analysis of recreational water.

UI	MeSH Term	Description	Entries
D004755	Enterobacteriaceae	A family of gram-negative, facultatively anaerobic, rod-shaped bacteria that do not form endospores. Its organisms are distributed worldwide with some being saprophytes and others being plant and animal parasites. Many species are of considerable economic importance due to their pathogenic effects on agriculture and livestock.	Coliform Bacilli,Enterobacteria,Ewingella,Leclercia,Paracolobactrum,Sodalis
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
