Abstract

This study was carried out in Raparin Pediatric hospital in Erbil city, from the beginning of July 2015 to the end of May 2016. Stool samples (No.= 548) were collected from children of less than 1 month to 13 years of age of both genders (307 males and 241 female). The study was designed to diagnose Cryptosporidium spp. among diarrheic children with the aid of direct and formalin-ether sedimentation acid fast stain.

The study revealed that the total rate of infection with Cryptosporidium spp. among children was 10.77%, and the peak of oocyst positive rate of infection was occurred in children at age 2-4 years (14.28%), followed by the age group ≤ 2 years old (11.29%), while the lowest rate of infection was reported in the age group > 6 years (7.87%).

Regarding to the gender, there was significant differences between males and females (p<0.05), the rate of infection was higher among males (13.68%) than females (7.05%).

The results of infection with cryptosporidiosis revealed non-significant difference among urban, rural and sub-urban area with the rates 12.01%, 10.17% and 7.41% respectively.

In relation to the months of the study, highly significant (p<0.001) differences were revealed. The highest rate of infection with cryptosporidiosis was observed in August 2015 (21.33%), while the lowest was 1.51% in March 2015. On the other hand, there were no reported positive cases (0.0%) for July 2015 and March 2016.

The rate of double-infection with Cryptosporidium spp. and other intestinal microorganisms was 6.94% from a total of 72 positive samples. Out of them, in five stool samples, which were three positive cases (4.17%) with Blastocystis hominis, followed by one positive case (1.39%) for each Alternaria spp. and Rotavirus in combination to Cryptosporidium spp.

From data of the study, it was found that one case (0.18%) for each E. histolytica, Chilomastix mesnilii and Hymenolepis nana was reported, then came three (4.16%) and seven (9.72%) positive cases for both Giardia lamblia and B. hominis respectively. Regarding to Cryptosporidium spp. 59 positive cases (18.94%) were reported, statistically showed highly significant (p< 0.0001) compared to other reported parasite species.
