Protozoan.
Protozoan (protozoanosis) or protozoal disease - a group of diseases caused by protozoan organisms. The simplest organisms are single-celled living organisms that are both a cell and a full-fledged organism, which is characterized by many vital functions: movement, metabolism, reproduction. Parasitic protozoa are of the sporozoan type. Sporozoans can parasitize not only in humans or animals, but also in organisms of fish, marine animals, insects and worms, which puts the latter among potential carriers of parasitic diseases.
The danger of infection by protozoal organisms lies in the intoxication of the host organism and the suppression of its immune system, which occurs as a result of their vital activity, and the possibility of sexual and asexual reproduction (through multiple cell division of the protozoan organism) allows protozoa to travel from one host to another.
Due to their microscopic size, protozoal organisms are able to spread and inhabit not only various tissues of the body, they have the ability to penetrate into the bloodstream and lymph flow, and, moving in this very way, they affect almost any structure of the host's body. Some protozoal diseases can go unnoticed for humans, but many of them can be fatal if medical care is not provided in a timely manner.
You can get a protozoal infection:
- by contact with a carrier of the disease (sexually);
- by consuming contaminated food and water;
- by violating the rules of elementary hygiene, when the source of infection is in soil, water;
- by contact with infected animals;
- through insect bites.
Identification of the causative agent of protozoal infection occurs with the help of bacteriological examination of a smear from the rectum, urethra, vagina; when carrying out the reaction of immunofluorescence and polymerase chain reaction (PCR), enzyme immunoassay.
Signs of protozoal infection in the body are different depending on which systems affect protozoal organisms, but the most frequent manifestations of protozoal infection in the body can be intestinal disorders arising for unknown reasons (diarrhea, vomiting), fever, inflammation of the mucous membranes, general weakness , drowsiness. Each of these symptoms in itself can be a signal for an urgent examination.
