| parotid enlargement, forehead edema, and suppression of malaria as nutritional consequences of ascariasis. | bilateral painless enlargement of the parotids, a curiously localized edema of the forehead and relative freedom from malaria were striking findings in children of anjouan but not of grande comore, two neighboring islands of the comorro group in the indian ocean. compared with those of grande comore, anjouan children were heavily infested with ascaris lumbricoides. we suggest that the clinical findings may be the nutritional consequence of severe ascariasis and that the low incidence of malaria ... | 1977 | 930882 |

| soil-transmitted helminth infections among plantation sector schoolchildren in sri lanka: prevalence after ten years of preventive chemotherapy. | the plantation sector in sri lanka lags behind the rest of the country in terms of living conditions and health. in 1992, a sector-wide survey of children aged 3-12 years and women of reproductive age showed >90% prevalence of soil-transmitted helminth infections. biannual mass de-worming targeting children aged 3-18 years started in 1994 and was continued until 2005. the present study was carried out to assess the status of infection four years after cessation of mass de-worming. | 2011 | 21980549 |
| functional associations of similar mhc alleles and shared parasite species in two sympatric lemurs. | several recent studies of animals in their natural surroundings found evidence for effects of certain major histocompatibility complex (mhc) immune gene alleles on the parasite load. however, in multi-infected individuals the particular selection pressure exerted by specific parasites has rarely been explored. in this study we took advantage of the parasitological and genetic data of two previously investigated malagasy lemur species (cheirogaleus medius and microcebus murinus). we investigated ... | 2010 | 20363374 |
