Studies on the Biology of some Oxyurid Nematodes. I. Factors in the Development of Eggs of Aspiculuris tetraptera Schulz

Abstract

An investigation of the factors necessary in the development of eggs of the mouse pinworm, A. tetraptera, outside the host, have shown that both oxygen and a suitable temperature (20–30°C.) are necessary. Development at high temperatures (37°C.) leads to a reduction in the number of infective eggs. It has also been demonstrated that there exists in the development of the infective eggs, a period of incubation during which the infective larvae within the eggs, though morphologically well-developed, are incapable of hatching.
