Drinking Water Source And The Prevalence Of Giardia Lamblia And Cryptosporidium Parvum Among Children In Selected Villages Of Pawi Special District Benishangul-gumuz Region.

Giardia lamblia and Cryptosporidium parvum are parasitic protozoans that infectrnhumans as well as domestic and wild animals all over the world. These parasites arernimplicated in many water borne disease outbreaks in different parts of the world. Thernpresent study was conducted to assess the prevalence of these two parasites amongrnchildren below 14 years old that drink water from unprotected water sources-Ali-spring,rnDiga dam, and hand dug wells and “protected” wells with hand pumps in selectedrnvillages (Almu, K2V24 and K2V23/45) in Pawi Special District Benishangul-GumuzrnRegion. Single stool specimens were collected from a total of 384 children from the threernvillages. For identification of Cryptosporidium parvum the modified Ziehl-Neelsenrnstaining method was used. Giardia lamblia was detected using direct microscopy basedrnon wet mount and formalin-ether concentration techniques. Out of the 384 childrenrnexamined, 102 (26.6%) and 31 (8.1%) were found positive for G.lamblia and C.parvumrninfection, respectively. Overall co-infection with intestinal parasites was detected inrn4.4% of the study participants, in which G.lamblia and C.parvum comprised the highestrnproportion. Prevalence of giardiasis in female children was significantly higher than inrnthe males (p0.05). G.lamblia and C.parvum infectionrnprevalence was not significantly different among the different age groups (p>0.05). Onrnthe other hand, the prevalence of G.lamblia and C.parvum was associated with thernsource of drinking water with more cases of giardiasis detected in study participantsrnusing water from unprotected water sources than those using the “protected” waterrn(p
