RESUMO
An analysis of 1,953 stools - 194 from Lawrence Tavern and 1,659 from Bellevue Hospital - was done. In the rural area (Lawrence Tavern) the predominant parasites were Ascaris lumbricoides, Necator americanus, Entamoeba coli and Trichuris trichiura. In the urban area (Bellevue Hospital) there was a reversal of this order - Trichuris trichiura being the main finding followed by Entamoeba coli, Necator americanus and Ascaris lumbricoides. Stools from a small percentage of Hookworms and Ascaris cases were studied by egg counts and a comparison of direct examination and concentration methods was made. Positive cases of Hookworm, Ascaris and E. histolytica were treated with CI-416 and Humatin and with current drugs for comparison. The results show that CI-416 is not as effective as Alcopar and Antepar respectively, against Hookworm and Ascaris. Humatin on the other hand seems to be very effective against E. histoytica. Side effects with the trial drugs were minimal and were limited to minor gastrointestinal symptoms in a few cases (AU)
