Abstract
Of 101Escherichia coli isolates from raw meat, food handlers and equipment 24.8% showed enterotoxigenicity, 22.7% surface hydrophobicity and there was a high incidence of resistance towards metal ions such as mercury, cadmium and silver. Only 6% of the strains were colicin producers. Significant statistical correlation was observed between enterotoxin production and cadmium and mercury ion resistance.
Résumé
Center une souches d'Escherichia coli ont été, isolées de viandes crues, de manutantionneurs de nourriture et d'equipement de boucherie. Elles exhibent une enterotoxigénécité à concurrence de 24.8%, une hydrophobicité de surface à concurrence de 22.7%. Il y a une grande fréquence de résistance vis-à-vis d'ions métalliques comme le mercure, le cadmium et l'argent. A peine 6% des souches sont productrices de colicine. Il y a une corrélation significative sur le plan statistique entre la production d'enterotoxines et la résistance aux ions cadmium et mercure.
