The characteristics of common enteric protozoa reported in study of 5792 specimens from US patients collected in 2000[14]. Studies from the 1980's reported Blastocystis was usually found as a co-infection with Giardia or Entamoeba histolytica in symptomatic patients [139, 140], which was not the case in 2000 [14]. In 2000, the number of symptomatic patients who were found to be singly infected with Blastocystis (400) exceeded the number of samples found positive for Cryptosporidium, Giardia, and Entamoeba histolytica combined. Patients singly infected with Blastocystis were as likely to be symptomatic as patients singly infected with Cryptosporidium (69% vs. 70%) [14].
