| the relative influence of polyparasitism, environment, and host factors on schistosome infection. | where prevalence of geohelminths and schistosomes is high, co-infections with multiple parasite species are common. previous studies have shown that the presence of geohelminths either promotes or is a marker for greater prevalence and intensity of schistosoma mansoni infections. some of this apparent synergy may simply represent shared conditions for exposure, such as poor sanitation, and may not suggest a direct biologic interaction. we explored this question in a study of 13,279 school childr ... | 2007 | 17978069 |
