Substrate degradation and protein synthesis served as indicators of metabolism in virulent Treponema pallidum. Opitmal metabolic activity in these spirochetes was observed at 10 to 20% O2 concentrations, with markedly reduced activity at higher or lower O2 levels or under anaerobiosis; alternate functioning electron acceptors that might substitute for O2 were not found. Carbon monoxide and cyanide at concentrations that inactivate cytochrome oxidase were not effective metabolic poisons for T… CONTINUE READING
