Age-related worm load and worm fecundity patterns in human populations, as indicated by schistosome circulating antigens

ABSTRACT

Recently, our group determined the relationship between serum CAA levels and fecal egg counts in two foci very intense Schistosoma mansoni transmission Maniema (Zaire), an area endemic for S. mansoni since several decades, and Ndombo (Senegal), where transmission has only been established since a few years. The objetive was to study and compare age-related worm load and worm fecundity patterns in these two different endemic settings. Here, we will summarize the most important findings and conclusions of this study.
