Enterocytozoon bieneusi infection in patients without evidence of immunosuppression: two cases from Zimbabwe found to have positive stools by PCR.
Patients infected with human immunodeficiency virus (HIV) often also have intestinal infections with Enterocytozoon bieneusi. Recently, infection with this microsporidian has been described in immunocompetent subjects, mainly from Europe. When the stools of six HIV-negative patients who presented with diarrhoea in Zimbabwe were investigated, using a recently described protocol based on PCR, two patients were found to have E. bieneusi infections. These two individuals presented with a self limited diarrhoea, abdominal cramping and nausea. These data indicate that E. bieneusi may be a more common cause of diarrhoea in Zimbabwe than previously thought. Larger, prospective studies are needed.
