Abstract
THE concentration of eggs or larvae of parasitic nematodes in the faeces of host animals has long been regarded as an indication of the number of mature parasites present. Several causes of variation in the relationship between the number of worms and the faecal egg count have been considered, among them changes in the quantity of faeces passed and in its consistency, and diurnal fluctuations in count have been much studied. Moreover, it is recognized that the ovulation of parasites in a resistant host may be inhibited.
