The maximum growth temperature and human pathogenicity of psychrotrophic aeromonads.

Determination of the maximum growth temperature of Aeromonas strains isolated from clinical material and endowed with pronounced propensity for adhesion to intestinal cells has demonstrated that all strains still grow at 39 degrees C, with this holding true for the majority of strains also at 40 degrees C. Since Aeromonas isolated obtained from water evidence to a large extent a markedly lower maximum growth temperature, the 39 degrees C growth criterion is a characteristic of Aeromonas strains isolated from clinical material.
