Enterobius vermicularis (pinworms), introital bacteriology and recurrent urinary tract infection in children.

The relationship between pinworm infectation and introital cultures was investigated in 2 groups of girls. Those children with recurrent urinary tract infections were compared to agematched controls who had never had a urinary tract infection. We found a higher incidence of enteric organisms on the introital area and pinworm ova on the perianal skin in the group of girls with recurrent infection.
