title: Studies on infectivity, longevity and fecundity of Ancylostoma ceylanicum in golden hamsters.
abstract: Ancylostoma ceylanicum is a new introduction as an experimental hookworm model. Information on the biology of this parasite in its laboratory host--the golden hamster, is meagre. Its infectivity, longevity and fecundity were studied to obtain relevant information especially on vulnerable points in the maintenance and continuation of the infection. 100% infectivity was obtained with an inoculum of 60 larvae per animal. Maximum numbers of parasites were harboured from day 15 to day 18 after infection and thereafter gradually declined. Approximately 10% of the worms were still present at the end of the third month of infection. The in vitro release of eggs in a 24-hour period by one female nematode peaked from day 25 to day 39, a second rise occurred in day 70 after infection.
