Abstract
Forty strains of Plesiomonas shigelloides representing environmental and clinical isolates were characterized as to their tolerance to sodium chloride, acid and alkaline conditions and growth temperatures. In Tryptone broth all isolates grew in 3% but not 4% sodium chloride; whereas, in Trypticase Soy broth all isolates grew in 4% and 65% of them grew in 5% sodium chloride. All isolates initiated growth at pH 4.5 and 8.5 and 58% of the isolates grew at pH 4.0. Only 22% of the isolates grew at 8°C and 25% of them grew at 45°C. Heating at 60°C for 30 min destroyed all isolates tested.
