Information ⬇

On multiple days, fecal samples should be examined for oocysts (4-5 µm in diameter, smaller than most parasites). Although conventional stool examination for ova and parasites does not detect Cryptosporidium, modified acid-fast staining, direct immunofluorescent techniques, and EIAs can facilitate diagnosis.

Treatment: Cryptosporidiosis

  • Nitazoxanide (500 mg bid for 3 days) is effective for immunocompetent pts but not for HIV-infected pts; improved immune status due to antiretroviral therapy can alleviate symptoms in the latter pts.
  • In addition to antiprotozoal agents, supportive measures include replacement of fluid and electrolytes and use of antidiarrheal agents.
