Hydrogen Sulfide-Producing Variants of Escherichia coli

AUTOR(ES)
RESUMO

Seventeen strains of H2S-producing variants of Escherichia coli were isolated from specimens submitted for microbiological study (ten from stool, five from urine, and two from postmortem material). Production of H2S was unstable in several strains; however, other than their production of H2S, all strains closely resembled typical E. coli in their biochemical reactions. In vitro susceptibilities of the H2S-producing variants to antimicrobics closely resembled those of typical E. coli in this laboratory.
