RESUMO
Data are presented for the first country wide prospective study on gastrointestinal tract parasitic infections done in Jamaca. Samples from 2,947 young Jamaicans drawn from all ecological zones and from all parochial divisions of the island were analyzed. Pica was practised by 8.6 percent. Generally, prevalence of organisms was as follows: Trichiuris trichiura (12.3 percent). Ascaris lumbricoides (9.5 percent), hookworm (2.2 percent), Strongyloides stercoralis (0.35), Giardia lamblia (6.3 percent) and Entamoeba coli (7.7 percent). Several other species of protozoans were recorded. Prevalence of A. lumbricoides, T. trichiura and Necator americanus was significantly greater in upland than in lowland (both rual and urban), while the situation was reversed for G. lamblia-infections. Greatest variations were age-related. A.lumbricoides and T. trichiura reached peak prevalence of 15-19 years of age. Suggestions are made for a national and even regional antihelminthic program for the mass treatment of pre- and primary school age children. (AU)

A gastrointestinal tract parasitological study was done on 2,947 young Jamaicans drawn from all ecological zones and from all parochial divisions of the island where pica was practised by 6.9 percent. Generally, the prevalence was Trichuris 12.3 percent, Ascaris 9.5 percent, Hookworm 2.2 percent, Strongyloides 0.3 percent, Giardia 6.3 percent and E. coli 7.7 percent. Several other spp. of protozoans were recorded. Prevalence of Ascaris, Trichuris and Necator was significantly greater in upland than in lowland areas, both urban and rural, while the situation was reversed for Giardia infections. Greatest variations in prevalence were age-related. Ascaris and Trichuris reached peak prevalences of 15.3 percent and 20.5 percent, respectively, in 5-9 year olds, while Hookworm peaked later at 15-19 years of age. Suggestions are made for a national, even a regional, antihelminthic programme for the mass treatment of pre- and primary school age children. This would aim at the eventual eradication of helminthiasis in the region (AU)

A description is given of the ultrastructure of Giardia lamblia found in three jejunal biopsies from children. The unique median body, vacuoles and cytoplasmic clefts of this protozoon are illustrated. No evidence of penetration of the trophozoite into the jejunal mucosa or deeper tissues is demonstrable.(AU)

Humatin was well tolerated, and eliminated E. histolytica infection as determined by stool examination in sixty percent of cases. The drug appeared to be more effective in older individuals than in those under eight years of age. It eliminated abdominal cramps, fever, nausea, vomiting and weakness in most cases in which these symptoms were present before treatment (AU)
