Giardiasis

on 20.1.09 with 0 comments



Giardia lamblia (G. intestinalis, G. duodenalis) is a unicellular parasite (flagellate) which causes intestinal infections. The infections are often asymptomatic and Giardia was for a long time thought to be apathogenic. Since 1981 it has been regarded as potentially pathogenic and as the cause of diarrhoea and various forms of abdominal discomfort. In developing countries the infection occurs often in children but its frequency diminishes as they grow older. Related species infect amphibians (G. agilis) and rodents (G. muris). G. psittaci and G. ardeae both infect birds. G. lamblia itself may infect various animals, including dogs, cats and beavers.
