Abstract
Manifestation of oxyuriasis occurring in mothers and their children was investigated as found in the following results.
1. In the housewives of 58 households, each of whom had a child or children, the presence of eggs of E. vermicularis in the anal and perianal regions was examined. In thirteen (22.4 per cent) of the housewives, harboring such eggs was found. Twenty-six (86.6%) out of 30 children living with these families were also revealed to have eggs of E. vermicularis. Of 105 children of 45 housewives who gave negative results in eggs of E. vermicularis, 26 children (24.7 per cent) were proved to harbor the eggs.
2. The relationship between age and rate of positive detection of eggs of E. vermicularis among mothers and their children both of whom had given positive egg tests, showed that a relatively high positive rate was found in age groups of 26 to 30 and 31 to 35 years among the mothers and in a age group of 10 years of the children.
From these results, it is presumed that these children, including infants, may constitute an important source of infection with E. vermicularis for their mothers.
3. The housewives of 90 households without children gave all negative results in the eggs of E. vermicularis.
