Pathological Factor
Giardia lamblia infection of the human small intestine is a common protozoan cause of diarrheal disease worldwide and two major Giardia genotypes, assemblages A and B, infect humans. Currently, there are seven defined variants (assemblages) of G. intestinalis, with only assemblages A and B being known to infect humans. Although assemblage B is the most prevalent worldwide
Disease
People get giardiasis by consuming food or water contaminated with cysts (the infective stage of the organism); Giardiasis occurs throughout the population, although the prevalence is higher in children than adults. Chronic symptomatic giardiasis is more common in adults than child.it responsible to cause Diarrhea, malabsorption
