Thermal-death times of opaque and translucent morphotypes of Vibrio vulnificus.
Thermal-death times were determined for Vibrio vulnificus strains with different morphotypes. Opaque strains showed higher D values (times required to reduce the viable population of a given strain by 90%) than translucent strains. Z values (absolute values of the temperature required to reduce 1 log scale of D values) were also significantly higher in opaque morphotypes (2.4 to 2.5 degrees C) than in translucent ones (1.7 to 2.1 degrees C). These results indicate that the morphotype is related to the organism's susceptibility to heat.
