ABSTRACT

Prevalence of infection with the intestinal helminths, Ascaris lumbricoidesTrichuris trichiuraAncylostoma duodenale and Strongyloides stercoralis was examinedin 632 residents of communities in Esmeraldas province of Ecuador. These communities were divided into two groups according to area of habitation which reflected different socioeconomic circumstances. Attempts were made to correlate infection status with race and ABO blood group phenotype. The racial groups included blacks, Chachi amerindians, and mixed-race mestizos. Greater prevalences of infection were seen in the area oflower socioeconomic status. No racial or blood group associations with helminth infection were seen controlling for socioeconomic status.

Keywords: Helminth parasites. Race. ABO blood group phenotypes. Socioeconomic status.


RESUMO

A prevalência de infecções com helmintos Ascaris lumbricoidesTrichuris trichiuraAncylostoma duodenale e Strongyloides stercoralis foi examinada em 632 pessoas em diferentes comunidades na Região de Esmeraldas no Equador. Estas comunidades foram divididas em dois grupos conforme a área na qual residem, o que reflete diferentes circunstâncias sócio- econômicas. Intentou-se correlacionar os tiposde infecção com a raça e os grupos sanguíneos ABO. Nestes grupos raciais estão incluídos negros, ameríndios Chachi, e mestiços. Notou-se a prevalência de infecções nas áreas sócio-econômicasmais baixas. Não se encontrou nenhuma relação com a infecção helmíntica e raça ou grupo sanguíneo depois de controlar-se o status sócio- econômico.

Palavras-chave: Parasitos helmintos. Raça. Grupo sanguíneo ABO fenótipo. Status sócio-econômico.
