A simplified culture method for Blastocystis hominis

چکیده
edigraphic.com Blastocystis hominis is a strict anaerobic protozoan that occurs in the intestine of humans and other mammals (Zierdt, 1991). Recently, phylogenetic analyses of ribosomal RNAs place B. hominis within the straminopiles (Silberman et al., 1996). Its pathogenic role in human beings is still disputed by some investigators (Markell and Udkow, 1986; Miller, 1988). The mechanism by which it can lead to diarrhea is not understood. Diagnosis of clinical stool samples is generally based on finding of typical forms described in textbooks (Healy, 1991; Pessoa, 1988). However, these references do not mention the different forms of Blastocystis hominis such as those Rito Zerpa L,*,** Luis Huicho,*,** C Náquira,* I Espinoza *
