| Abstract | 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 children in Jequié, Bahia, Brazil, with a survey of demographic characteristics and
stool examinations. Cross-sectional analysis revealed a statistically significant increase in the prevalence and intensity of
S. mansoni infection with increasing numbers of geohelminth species (OR 2.5, 95% CI 1.38–3.64). Less than 20% of the
strength of this association was contributed by socioeconomic status or environmental conditions. Thus, polyparasitism
itself, as well as intrinsic host factors, appears to produce greater susceptibility to additional helminth infections. | pt_BR |
