Abstract

The influence of temperature on the development and embryonation of Ascaris suum eggs was studied using coarse sand medium in an environmental chamber with 50% humidity. The time required for development and embryonation of eggs was examined under 3 different temperature conditions, 5°C, 25°C, and 35°C. A. suum eggs did not develop over 1 month at the temperature of 5°C. However, other temperature conditions, 25°C and 35°C, induced egg development to the 8-cell-stage at days 5-6 after incubation. All eggs examined developed to the 8-cell stage at day 6 after incubation in the sand medium at 25°C. The higher temperature, 35°C, slightly accelerated the A. suum egg development compared to 25°C, and the development to the 8-cell stage occurred within day 5 after incubation. The formation of larvae in A. suum eggs at temperatures of 35°C and 25°C appeared at days 17 and 19 after incubation, respectively. These findings show that 35°C condition shortens the time for the development of A. suum eggs to the 8-cell-stage in comparison to 25°C, and suggest the possibility of accelerated transmission of this parasite, resulting from global warming and ecosystem changes.
