ABSTRACT
The study was conducted at a primary school in Abis 8 Village. Eighty- eight children aged 11 years participated in the present work. After fecal examination, 43 cases were found infected with Cryptosporidium. The mean oocysts number per high power field [HPF] ranged 1.6-48 oocysts/HPF. Azithromycin, praziquantel [PZQ] and mirazid were given to 13, 16 and 14 infected children, respectively. Three weeks after treatment, azithromycin and praziquantel gave cure rates of 91% and 56.2%, respectively, with a% reduction of oocysts in stools of 99% for azithromycin and 71.5% for PZQ. Mirazid was not effective. All the three drugs were well tolerated. The study showed that azithromycin is highly effective in the treatment of children with cryptosporidiosis and that PZQ decreases the infection rate and intensity
