RESUMO
Forty-five strains of enteroaggregative Escherichia coli were tested for hemolytic activity with different culture media and erythrocytes from different species. Thirty-seven strains showed proteinase K-sensitive contact hemolysin activity with sheep erythrocytes when cultured in Casamino Acids-yeast extract broth supplemented with 1 mM calcium chloride and when cultured in nutrient broth media. The production of contact hemolysin was dependent on temperature, pH, and culture conditions.
