<i>Blastocystis</i> subtypes in symptomatic and asymptomatic family members and pets and response to therapy

Abstract

Conventional therapy is ineffective for symptomatic Blastocystis infection. The high prevalence of Blastocystis infection within households suggested transmission between humans and their pets. Subtyping analysis of SSU rDNA alone in Blastocystis does not appear to predict pathogenicity.
