Gibberellic acid

Giardia lamblia, also known as Giardia intestinalis and Giardia duodenalis, is a flagellated parasite that colonizes and reproduces in the small intestine, causing giardiasis. The parasite is a microaerophile, which means it is able to survive in an environment with low levels of oxygen.

Life Cycle

The life cycle of Giardia lamblia consists of two stages: the trophozoite and the cyst. The trophozoite stage occurs in the host's intestine and is responsible for the symptoms of giardiasis. The cyst stage is the parasite's dormant form, which can survive outside the host and is responsible for transmission of giardiasis.

Transmission

Giardia lamblia is transmitted via the fecal-oral route. The most common methods of transmission include ingestion of contaminated water or food, person-to-person contact, and contact with animals.

Symptoms and Treatment

Symptoms of giardiasis include diarrhea, abdominal pain, nausea, and vomiting. Treatment typically involves antiparasitic medications such as metronidazole or tinidazole.

Prevention

Prevention of giardiasis involves practicing good hygiene, avoiding drinking untreated water, and cooking food thoroughly.
