The present study was conducted to assess the prevalence of Giardia species infection in cattle
and human. One hundred of animal fecal samples and 139 human stool samples were collected
from different veterinary clinics and its related hospitals respectively. All samples were undergone
to microscopically examination by; direct smears in 0.90% Na Cl solution, Lugol's iodine stain for
cyst detection and formol-ether concentration. 9 (28.1%) calves from 32 were positive in
microscopic examination by the used techniques. 25% of the examined fecal samples of cattle
(17/68) were containing cysts of Giardia species by microscope. 39 of 139 (28.1%) of human stool
samples were found infected by this protozoon. Regarding the sex of human cases, 26.30% of
examined males were positive while 30.20% of females were positive. The age factor in human
infection was clear; the age group of 11 to 20 years were the more infected than the other group (1-
10ys). There is no relation between form of human stool and infection rate. ELISA kits confirmed
that 6 % of animal cases and 15.8% of human were positive. The epidemiological aspects were
discussed in the study.
