Effects Of Temperature

Recent interest in causes of Dungeness crab (Cancer magister) population fluctuations led to a study of temperature and salinity effects on survival and growth of zoeae.Preliminary work developed methods for culturing larvae in flasks with good survival. A comparison of survival of larvae fed two different diets showed the nauplii of the barnacle Balanus glandula and larvae of the bay mussel Mytilus edulis were suitable and unsuitable food organisms, respectively.The optimum ranges of temperature and salinity for laboratory-cultured C. magister zoeae were 10.0–13.9 C and 25–30‰, respectively. Zoeal survival was not significantly affected by temperatures and salinities approximating ocean ranges of these variables off the Oregon coast during the larval period. The growth rate of C. magister zoeae was directly related to temperature, but salinities that favored survival did not appear to affect the zoeal growth rate.

In vitro studies were conducted to determine the effects of temperature, pH, and competitive growth of other microorganisms on the viability and multiplication of Vibrio cholerae serotype Ogawa in reconstituted infant milk (nonsterile). Following inoculation of milk sample (at a pH range of 6.0 to 6.4), the V. cholerae population detected on thiosulfate-citrate-bile sucrose (TCBS) agar increased from 9.5 × 103 per g to 7.4 × 104, 2.6 × 108, and 1.9 × 109 per g after 12 h at 4°C, 25°C (room temperature) and 37°C, respectively. At a pH of 5.5, an approximate 100-fold rise in V. cholerae was observed after 12 h at 25°C, while within a pH range of 6.5 to 8.5, a five logarithmic increase in numbers was detected. The presence of other microorganisms did not appear to have any adverse effect on V. cholerae survival and growth in milk. The study demonstrates that at ambient conditions V. cholerae contamination of infant milk formula by carriers or infected mothers could lead to multiplication of the organism and hence pose serious health risk to infants.

Effects Of Temperature

Effects of temperature, salinity, water activity, and pH on survival and growth of Vibrio parahaemolyticus are reviewed. Maximum and minimum tolerances to these environmental factors are summarized, with special emphasis on conditions which exert stress or lethal effects on the organism. Behavior of V. parahaemolyticus as influenced by the interaction of environmental parameters is discussed.
