Protozoan Parasite

A healthy, normal, clean person still has 0.14 g of stool sticking on him. The stool may then have unicellular parasites attached, such as Giardia amoeba
Swimming in lakes can also be infected with protozoan parasites
Swimming is a good sport for everyone's health. However, if swimming in an unhygienic water environment, there is a possibility of infection with some protozoan parasites and microorganisms living in the water. Chlorine in swimming pool water does not kill all microorganisms immediately as many people think

. There are many species of microorganisms resistant to chlorine. So, even if chlorine water reaches an antiseptic concentration, it can take several hours, even days, to destroy them. While learning to swim, just swallowing a mouthful of pool water can make you sick When soaking in a pool, the amount of manure from all bathers can easily contaminate pool water If one person in the swimming pool has diarrhea, the amoeba parasite can be transmitted to all people in the pool.
Swimming outside of streams becomes more susceptible to protozoan parasites
Swimming in lakes, rivers, canals, oceans .



... is even more potential than the pool water. Water can be contaminated from upstream, due to many different reasons such as human excrement, animal dung, factory waste, domestic sewage, chemical waste, metal. Water will be more at risk of contamination after a heavy rain, sweeping upstream waste down with large numbers of protozoan parasites causing diseases, especially intestinal diseases
Infection can occur when drinking water while swimming, breathing in steam, or by direct contact with pool water, hot tubs, water parks, fountains, lakes, rivers, streams or the ocean
In the common microbiological agent that can be harmful to health in the country, Giardia is a type of intestinal protozoan parasite common in our country.
Giardia usually occurs in children more than adults. People infected with Giardia by swallowing the cocoon of Giardia protozoan parasite: by swallowing water from swimming pools, rivers, streams and lakes while swimming, drinking ice made from uncooked water, eating undercooked food Cocoon of Giardia protozoan parasite. In addition, close contact with a person who is ill due to Giardia is also a risk of infection.



. Direct contact with patient's blood does not infect Giardia protozoan parasites. Cocoons have an outer covering that makes them resistant to physical and chemical agents of the environment. The source is caused by an infected person or healthy person who has no clinical symptoms. After being cocooned into the body, it will escape cocoon in the small intestine, forming two nutritious forms The phytoplankton reproduces by dichotomy, living freely in the lumen of the intestine, or may attach to the small intestine epithelium. When Giardia moves to the large intestine, it will create cocoons. Can be picky about human excretion, infiltrate into other people through the digestive tract, through contaminated food and drink. The Gardia cystic form also follows the stool, but cannot spread the disease because it does not exist in the environment outside the body. Cocoons can survive for weeks or months in the external environment. Giardia is not spread by contact with dogs or cats, which are parasitic on humans.

Manifestations of patients infected with Gardia protozoan parasite
People infected with Giardia protozoan parasites may have no symptoms or may have acute, or chronic, diarrhea. Incubation period is about 1 to 3 weeks Diarrhea will progress from mild to severe. Patients with stools became more and more fluid, the number of bowel movements increased with mucus, but there was no blood. Stool has a foul odor, often has bubbles.

Gardia's disease lasts from 2 to 6 weeks in a person with a normal immune system. Children, the elderly, and people with chronic illness may extend the duration of the illness. If you are chronically infected with a Gardia protozoan parasite, the symptoms of diarrhea that occur over and over can lead to malabsorption syndrome.



In children, severe Giardia protozoan infection can cause mental and physical retardation. Gardia makes children lose weight, unable to absorb fat, lactose, vitamin A and vitamin B12.
Diagnosis of protozoan parasitic disease Giardia
Giardia protozoan parasite is diagnosed by finding cysts and trophic bodies in the stool. Occasionally, multiple stool tests can be performed, so the conclusion is negative only when there are at least 3 negative samples.
Treatment of Giardia protozoan disease
There are many drugs used to treat Giardia protozoan parasites, the first ones being Metronidazole, Tinidazole and Nitazoxanide.
