Intestinal helminths in relation to eosinophilic lung (tropical eosinophilia) in Singapore

The above survey based on a study of single stool specimens from 569 patients, drawn from a hospital population belonging to different ethnic groups and having different cultural backgrounds, failed to indicate an association between intestinal helminth infection and eosinophilic lung. The higher prevalence of eosinophilic lung in Indians than in the other ethnic groups, as reported previously, cannot be explained on a basis of differences in the prevalence of the intestinal helminths, Ascaris lumbricoides, hookworm, Trichuris trichiura and Strongyloides stercoralis.
