What is the meaning of Giardia lamblia?
Giardia lamblia: A parasite responsible for a contagious form of diarrhea. The parasite is most commonly transmitted through direct contact with infected feces or by eating food or drinking water contaminated by feces. Giardia is one of the most common intestinal parasites in the world.
Why is it called Giardia intestinalis?
Giardia duodenalis, also known as Giardia intestinalis and Giardia lamblia, is a flagellated parasitic microorganism of the genus Giardia that colonizes the small intestine, causing a diarrheal condition known as giardiasis.
What is the identifying characteristic of Giardia lamblia?
G. lamblia is pear shaped and has one or two transverse, claw-shaped median bodies; G. agilis is long and slender (100) and has a teardrop-shaped median body; and the G. muris trophozoite is shorter and rounder and has a small, rounded median body.
What type of parasite is Giardia lamblia?
Giardiasis is a diarrheal disease caused by the microscopic parasite Giardia duodenalis (or “Giardia” for short). Once a person or animal has been infected with Giardia, the parasite lives in the intestines and is passed in stool (poop). Once outside the body, Giardia can sometimes survive for weeks or even months.
What causes Giardia lamblia?
Swallowing contaminated water The most common way to become infected with giardia is after swallowing unsafe (contaminated) water. Giardia parasites are found in lakes, ponds, rivers and streams worldwide, as well as in public water supplies, wells, cisterns, swimming pools, water parks and spas.
How is Giardia intestinalis transmitted?
You can get giardiasis if you swallow Giardia germs. Giardia spreads easily and can spread from person to person or through contaminated water, food, surfaces, or objects. The most common way people get sick is by swallowing contaminated drinking water or recreational water (for example, lakes, rivers, or pools).
What is the classification of Giardia intestinalis?
ZooflagellateGiardia duodenalis / Class
What disease is caused by Giardia intestinalis?
Giardiasis is a diarrheal illness caused by Giardia intestinalis (also known as Giardia lamblia or Giardia duodenalis), a one-celled, microscopic protozoan parasite. The parasite is passed in the stool of an infected person or animal.
Where does Giardia lamblia live in the body?
Once a person or animal has been infected with Giardia, the parasite lives in the intestines and is passed in stool (poop). Once outside the body, Giardia can sometimes survive for weeks or even months. Giardia can be found in every region of the United States and around the world.
Where is Giardia lamblia found?
Parasites – Giardia Giardia is found on surfaces or in soil, food, or water that has been contaminated with feces (poop) from infected people or animals. You can get giardiasis if you swallow Giardia germs.
Where is Giardia lamblia found in the body?
Giardia parasites live in the intestines of people and animals. Before the microscopic parasites are passed in stool, they become encased within hard shells called cysts, which allows them to survive outside the intestines for months. Once inside a host, the cysts dissolve and the parasites are released.
How is G lamblia transmitted?
What is the morphology of Giardia intestinalis?
The cysts of Giardia intestinalis are 8 – 12 µm in size and are ellipsoid in shape. They contain 4 nuclei which do not tend to be obvious. Longitudinal fibrils consisting of the remains of axonemes and parabasal bodies may also be seen. Cysts may appear to shrink from the cell wall.
What disease is caused by Giardia lamblia?
Giardiasis is a diarrheal illness caused by Giardia intestinalis (also known as Giardia lamblia or Giardia duodenalis), a one-celled, microscopic protozoan parasite.
What are the diseases associated with G lamblia?
Infection with Giardia lamblia causes a chronic diarrheal disease called giardiasis that is characterized by steatorrhea (fatty stools), abdominal cramps, bloating, frequent loose stools, fatigue and weight loss. Reactive arthritis is a common complication after a severe and chronic episode of giardiasis.
What are the two morphological features of Giardia lamblia?
Giardia lamblia has two forms, cyst, and trophozoite.
What is life cycle of Giardia lamblia?
G. lamblia has two life stages: a motile, replicative trophozoite stage, in which the parasite survives in the small intestines of the host, and a nonreplicative cyst stage, in which the parasite survives in the environment.
What is the class of Giardia intestinalis?
