In permanent preparations stained according to Heidenhain, balantidia, as well as in native smears, are easily detected at low magnification of the microscope.

The main features for their recognition are the characteristic oval shape of the body and a large dark-colored bean-shaped or sausage-shaped macronucleus, located inside the cytoplasm of the protozoan in the transverse, oblique or longitudinal direction. Details of the structure of balantidia are studied at high magnification of Inderal pills.

The macronucleus is clearly visible, and sometimes the small micronucleus adjacent to it, contractile vacuoles in the form of light uncolored vesicles in the front and rear parts of the body, digestive vacuoles filled with bacteria, fungi, starch grains, erythrocytes and leukocytes at various stages of digestion. The cilia covering the body of the protozoan are poorly visible. Balantidia cysts are round, 40-65 μm in diameter, with a double-contoured membrane and a well-marked bean-shaped nucleus.
Preparations aimed at eliminating parasites are used in the form of 2-3 five-day cycles. Assign monomycin 0.15 g 4 times a day, oxytetracycline 0.4 g 4 times a day, metronidazole 0.5 g 3 times a day. The interval between cycles is 5 days.

The prognosis for modern therapy is favorable. Without the use of inderal pills therapy, mortality reached 10-12%. Prevention of Balantidiasis. To prevent the disease, it is necessary to observe hygiene measures when caring for pigs, as well as timely detection and treatment of people with balantidiasis. General preventive measures are the same as for dysentery. Balantidiasis - the first symptoms and methods of treatment.
Balantidiasis is a protozoan infection. The causative agents of infection are parasitic protozoans Balantidium coli. These microorganisms parasitize humans, pigs, and very rarely rats and dogs. This type of ciliates can cause not only balantidiasis, but also ciliate dysentery. This pathogen has become a giant in size among ciliates. The etiological agent of balantidiasis is the ciliary ciliate Balantidium coli. Balantidia are the largest representatives of intestinal protozoa that parasitize in the human body.
The life cycle of parasites goes through 2 stages - cystic and vegetative.

Balantidia cysts are about 50 µm in diameter, round in shape, and can survive outside the host for 3-4 weeks. The length of propranolol pills forms of parasites is 30-150 microns, the width is 30-100 microns; the surface is covered with cilia, thanks to which movement is carried out.

In the external environment, vegetative forms are less stable - they die after 3-5 hours. The main reservoir of balantidiasis pathogens are pigs, among which invasion reaches 60-80%; less commonly, humans are the source of protozoal infection. The mechanism of infection with balantidiasis is fecal-oral. The transmission of balantidia (usually cystic forms) occurs through dirty hands, contaminated water, fruits, and vegetables. More often, workers of pig farms, slaughterhouses, and meat shops fall ill with balantidiasis. In the human digestive tract, cysts form vegetative forms that parasitize in the tissues of the blind, sigmoid and rectum. At the site of their introduction into the colon mucosa, areas of inderal and edema are formed, which later transform into erosions and ulcers.
Mucosal defects are crater-shaped, uneven edges, bottom covered with necrotic masses. Ulcerative-destructive changes in the intestine, the absorption of toxic substances, as well as the nutrition of parasites at the expense of their host form the basis of the pathogenesis of balantidae.iasis and determine its clinical manifestations.

Once in the gastrointestinal tract, the microorganism affects the intestinal wall, causing at the initial stage edema and hyperemia of the mucous membrane, which are replaced as the process progresses by hemorrhages and foci of necrosis, accompanied by powerful intoxication, which manifests itself: cramping pains in the abdomen; frequent false urge to defecate; weakness, deterioration in general well-being; an increase in body temperature to 38.5-39 ° C; headache, dizziness; decrease or complete lack of propranolol; liquid fetid stools with an admixture of blood, pus, mucus (10-15 times a day).
For the acute form of the disease, a stormy, detailed symptomatology is characteristic. After infection, the symptoms of balantidiasis are absent for 5-30 days (latent incubation period). Objective signs: the tongue is dry, covered with white coating, the liver and spleen are enlarged, the abdomen is sharply painful when pressed in the umbilical region and in the lower sections. There is a rapid loss of body weight, exhaustion develops within a few days (up to a week).
In chronic balantidiasis, periods of exacerbation that last from several days to a month are replaced by imaginary well-being, the vivid symptoms of the disease disappear for several months (on average, from 3 months to six months). The manifestations of the disease in this case are mild: slight pain in the abdomen, diarrhea 2-5 times a day (sometimes with an admixture of mucus, less often blood), there are no manifestations of intoxication. The main method for diagnosing balantidiasis is scraping of the affected epithelium, which is taken during sigmoidoscopy, and a smear taken from the patient's feces. Balantidia are easy to spot as they are the largest of the ciliates and are easily visible under a microscope.
