Helminthic infestation of candidates for seasonal farmwork in Canada, 1968 - abstract

ABSTRACT

Of a total 393 applicants for the seasonal farmwork programme 32.3 percent were suffering from worm infestation. The numbers of Indians and Negroes affected were approximately equal and Necator americanus was the worm present in 95.3 percent of all those affected. Infested candidates were treated. Those with Necator americanus received tetrachlorethylene, those with Ascaris lumbricoides recieved alcopar and results were good in these groups. There was a poor response to the treatment of Trichiuris trichiura with both tetrachlorethylene and alcopar (AU)
