Comparative study of two methods for the diagnosis of Enterobius vermicularis in the appendix.

A total of 1590 human appendices were collected and examined histologically for evidence of pinworm infection. The incidence of infection in appendices was 2.39%. In examining 100 appendices by both the histological and the parasitological methods, 3 and 7 samples respectively were seen to be infected by pinworm.
