general, "dysentery" means a disease of the digestive system, but can not be called one agent.Most often we meet with invasive agent such as dysentery amoeba.In latynski such an amoeba called Entamoeba histolytica, is a single-celled organism is anaerobic (ie oxygen, it is not necessary for the development).It is dangerous for humans and primates.Dysentery amoeba has infected at least 50 million people around the world, but because you need to know about the features of her life.
Cats and dogs can be carriers, but their share in the transmission of the disease is negligible.
What is the life cycle of a dysenteric amoeba?
begin with the moment when the pathogen gets into a person's mouth.The cycle of a dysenteric amoeba includes the step of cysts (resting forms) and trophozoite stage (active form).In the mouth gets cyst.It has four cores, the cell divides several times, as a result of a cyst turns out as many as eight trophozoites.In this form, they migrate to the colon, where by dividing a single trophozoite two turns.Some of them form cysts and come out with the feces, alone inside the cysts occur fission and get ready cyst with four nuclei, ready to infect a new host.Cysts do not tolerate heat, but humid environment favorable for them.No owner can live for several months.
Another part of amoeba enters through the mucosa into the blood, affecting the liver, brain and lungs.The amoeba can cause liver abscess.
However dysentery amoeba brings a lot of trouble and without liver disease.Sometimes the infection is not manifested externally, but over the years a person can be a carrier can infect others.On average, a year die of dysentery 70 thousand people in the world.Symptoms may be expressed as light liquid stool, but it is often severe diarrhea with blood and mucous particles Liver abscess can begin and without symptoms of the surface of the intestine.
Even if there are no symptoms, the carrier is dangerous, but because he is being treated on a par with the sick.The infection is transmitted to the food and water contaminated with cysts.However, simple hygiene practices can be helpful.Dysentery often confused with "traveler's diarrhea".The latter is not an amoeba dysentery, and viruses or bacteria.
talk about security measures.They are not very complicated, and their knowledge is very important.What to do to not get into the mouth dysentery amoeba?

Very often the disease begins to appear a year after infection.The amoeba lives in the intestinal lumen and is powered by other bacteria and food particles and mucus does not allow it to gain a foothold on the wall of the intestine.
