The presence of inorganic phosphate repressed the formation of alkaline phos-phatase enzyme but did not affect the formation of acid phosphatase enzyme. Twenty-two non-enteropathogenic Escherichia coli isolates exhibited 16 esterase isoenzyme patterns while 15 enteropathogenic isolates exhibited three patterns. No relationship was found between enteropathogenicity and acid or alkaline phosphatase isoenzyme patterns. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-65-2-175
