Amoebic dysentery in children
Amoebic dysentery in children – endemic protozoal disease of the colon, characterized by deep ulcerative lesions of the intestinal wall, inclination to the chronic course with periodic exacerbations and to metastatic damage to other organs (liver, spleen, lungs, etc.).
There are several different varieties of amoebae, but the most dangerous is the type Entamoeba histolytica. It is widely distributed in tropical latitudes. Ent. histolytica exists in the form of vegetative and encysted forms. The first of them has in its turn two forms – a large vegetative form (BVF) and a small vegetative form (IMF). BVF – a typical parasitic form, resides in the intestinal wall, without leaving the lumen of the intestine, feeds on red blood cells. In the patient’s chair it is found only in the acute period of the disease and then exclusively in the blood-mucous lumps, but not in the feces. When leaving the intestinal wall in the lumen of the gut, it either degenerates, or passes into the IMF, most often found in the stool of patients, especially with the cessation of an acute period. In the unfavorable conditions of the existence of an amoeba, there is an incest, i.e. transition of an amoeba to a resting state, characterized by high stability.
The causes of amoebic dysentery in children consist in the transmission of infection, the focus of which is mainly a person who carries amoeba. The greatest value in the spread of amoebic dysentery, according to epidemiological observations, is water. The maximum incidence comes usually at the end of the hot season, when, due to lack of water, the population begins to use for drinking by any water body. If you eat contaminated food containing free amoebae, infection will not happen because they usually die in the stomach due to its acidic environment. Food products are polluted by cysts especially often in places without adequate control by sanitary supervision. In addition to direct contamination by carriers, an important role is played by the transfer of infection by flies and only partly by dust. Salads washed with contaminated water are a common cause of infection. In water, the viability of cysts persists from 2 to 4 weeks, in the intestines of flies – up to 40-50 hours. Water heated to 68 ° C kills cysts for 5-10 minutes, 50% alcohol and boiling – instantly.
In practice, the only way to avoid infection is to ensure that everything that you eat or drink has been washed or sterilized properly and properly cooked. Prevention of amoebic dysentery is the rules of personal hygiene. Drinking water can be disinfected in the following ways:
- Boiling water from 10 to 15 minutes (a little more in mountain altitudes) and storing it then in a closed container;
- add water-cleansing tablets, then leave the mixture to stand for at least 15 minutes before use;
- use a water filtration device.
However, chemical methods of sterilization do not guarantee the complete destruction of all possible harmful microorganisms. Of great importance is sufficient supply of boiled water, protection of food from flies. In endemic foci, boiled water should be consumed not only for drinking, but also for washing, brushing teeth, washing dishes, etc. Do not eat dishes containing frozen foods, unpurified fruit. Ice cubes can be made from contaminated water, so you should avoid drinks containing ice cubes if you are not sure that water is decontaminated.
