Lamblia, also known as Giardia lamblia or Giardia intestinalis, is a microscopic single-celled parasite that primarily infects the small intestine of humans and animals. It belongs to the genus Giardia and is classified under the phylum Metamonada.
Giardia lamblia is a flagellated protozoan, meaning it possesses whip-like structures called flagella that aid in its mobility. These parasites have a distinct pear or teardrop shape and exist in two forms: trophozoites and cysts. The trophozoite stage is the active form that feeds and reproduces, while the cyst stage is a dormant, environmentally resistant form that allows the parasite to survive in unfavorable conditions such as outside the host's body.
Infections with Giardia lamblia commonly occur through the ingestion of contaminated food or water, as well as through person-to-person contact. Symptoms of giardiasis, the disease caused by Lamblia infection, often include diarrhea, abdominal pain, bloating, nausea, and weight loss. These symptoms are primarily a result of the parasite's ability to attach to the intestinal lining, impairing nutrient absorption and causing inflammation.
Treatment for Lamblia infection usually involves the use of medications such as metronidazole or tinidazole, which are effective in eliminating the parasite. Maintaining good hygiene practices, practicing safe water and food handling, and avoiding contact with infected individuals are important preventive measures to reduce the risk of Lamblia infection.
Overall, Lamblia, also known as Giardia lamblia, is a protozoan parasite that causes giardiasis and primarily infects the small intestine of humans and animals.
