Study Notes
Giardia Lamblia
- Giardia Lamblia is a parasite that can be spread through contaminated water and food, and is commonly found in travelers and campers who drink unfiltered or unpurified water.
Transmission and Risk Factors
- Contaminated water and food are the main sources of transmission.
- Backpackers and campers are at high risk due to lack of access to clean water and proper sanitation.
Symptoms
- Bloating, flatulence, and foul-smelling diarrhea are common symptoms of Giardia infection.
- Steatorrhea (fatty diarrhea) can occur due to excessive mucus production, leading to impaired absorption of nutrients in the intestine, particularly vitamins A, D, E, and K.
Trophozoite Form
- The trophozoite form is flagellated and has four flagella, two nuclei, and a ventral sucking disk (adhesion disk) for attachment to the intestinal wall.
- It absorbs nutrients from the intestinal lumen via pinocytosis.
Cyst Form
- The cyst form has a rounded triangular shape and exhibits "falling leaf" motility.
- It is the infectious form of Giardia and can survive outside the human body for weeks.
Diagnosis and Treatment
- Giardia infection can be diagnosed using ELISA stool antigen testing.
- Metronidazole is the common treatment for Giardia infection.
