Culture isolation and molecular identification of Blastocystis sp. in Brazilian human isolates: preliminary results
ABSTRACT Blastocystis sp. is a protist commonly found in stool samples of humans and animals. Biological and genetic factors of this organism remain controversial. The present study aimed to develop and implement the Blastocystis in vitro culture of Brazilian human isolates for routine use. The feca...
