Screening for intestinal parasites. Is a single specimen valid?
To assess the validity of a single stool or perianal swab specimen when screening for potentially pathogenic parasites, 88 residents of a centre for developmentally handicapped adults were screened by collecting on alternate days three stool samples and pinworm swabs. Both sensitivity and negative predictive values were so low that three samples were required for some parasites. The species being screened for and its underlying prevalence must be considered before collecting only one specimen to reduce laboratory costs.

Intestinal parasite control in an institution for developmentally handicapped adults.
An intestinal parasite eradication program consisting of antiparasitic drug treatment and hygiene measures was conducted at an Ontario residential facility for developmentally handicapped adults from October, 1989 to August, 1990. The prevalence of intestinal parasites in general was initially over 90% while that of pathogenic species was 59%. Six months later, overall prevalence and that of pathogenic species were reduced to 32.9% and 11%. In one subgroup, the reduction in the prevalence of pathogenic parasites was sustained for at least one year. However, the prevalence of non-pathogenic species was similar to the baseline level. Simultaneous treatment and application of hygiene measures appeared to be effective in reducing pathogenic intestinal parasites.
