Giardiasis Treatment and Prevention
The scanning electron micrograph (SEM) above (courtesy of CDC) revealed some of the
external ultrastructural details displayed by a flagellated Giardia lamblia protozoan parasite.
G. lamblia is the organism responsible for causing the diarrheal disease "giardiasis".
Some people suffered from giardiasis do not have any symptoms. However, when the
parasite does cause symptoms, the symptoms include severe watery diarrhea, without
blood or mucus. And, the stool floats, and smells very bad. It contains unabsorbed fats.
Other symptoms include abdominal cramps (gas), loss of appetite nausea and vomiting or
even a low-grade fever. Symptoms of chronic giardiasis include: periods of intestinal gas
abdominal pain in the area above the navel and poorly formed, "mushy" bowel movements.
Drink only from water supplies that have been approved by local health authorities. Wash
hands after every trip to the bathroom and especially before eating.
Protozoan cyst removal throughout all stages of the conventional treatment is largely
influenced by the effectiveness of coagulation pretreatment, which along with clarification
constitutes the first treatment barrier against protozoan breakthrough. Physical removal of
waterborne Giardia cysts can be achieved by properly functioning conventional filters,
providing that effective pretreatment of the water is applied. Disinfection by chemical or
physical methods is also required to inactivate/remove the infectious life stages of these
The current treatment modalities for protozoal diarrhoea include 5-nitrosoimidazoles,
iodoquinol, diloxanide furoate, paromomycin, chloroquine, and

Giardia lamblia is the one of the most commonly detected parasites in the intestinal tract of
humans.The parasite attaches itself to the lining of the small intestines in humans, where it
sabotages the body's absorption of fats and carbohydrates from digested foods.
