After cialis pills, pastures are changed and animals are returned to these areas after 4 years. Infected pigs are kept in stalls until they are naturally free of parasites. Polymorphosis and philicolosis of ducks. The causative agents are various species of the genera Polymorphus and Fillicollis. They are characterized by a spindle-shaped bodyfrom 6 to 25 mm in length, with a proboscis at the front end, armed with hooks. In Fillicollis, the anterior part of the body is also covered with hooks. They parasitize in the intestines of ducks and many species of wild birds.
Parasites develop with the participation of intermediate hosts. For Polymorphus, this is amphipod, for Fillicollis - crustacean (water donkey). The acanthocephalan eggs are excreted with feces into the water and swallowed by the intermediate hosts, in whose body the larva emerges from the egg and reaches infectivity in 60-70 days in polymorphus and in 35-40 days in philicollis. Birds become infected by cialis online intermediate hosts. The crustaceans in the gastrointestinal tract of the bird are digested, and the larvae of the parasites attach to the intestinal wall and reach the sexually mature stage in 27-30 days. Scabs live in the intestines for no more than a year. Forgetfulness is observed in June, July. The source of infection is stagnant water, especially overgrown with grass. Invasive larvae remain in crustaceans during their life of 2-3 years.
Diagnosis. An intravital diagnosis is made by the presence of eggs in the fecal masses, which are detected by the method of successive washings (see Methods for diagnosing helminthiases). Polymorphus eggs are large, fusiform, with a protrusion of the middle shell at the poles; in filikollis they are oval, without protrusion, half the size of the first ones. The post-mortem diagnosis was based on parasites found in the intestines. Polymorphuses are orange, 10-13 mm long, philicollis are white, more than 20 mm long.
The drug at a dose of 0.5 g per 1 kg of bird weight is given with food using a free-group method. Ducks are not released to buy cialis bodies for two days after deworming. There is no treatment for philicolosis. These drugs are weak.
Reservoirs change 3-4 times a season. Prophylactic deworming of adult ducks is carried out 3-4 weeks after being put into stall keeping and preimaginal deworming of young animals 20-25 days after entering the infested water bodies. For grazing, ducks are taken away by deep lakes and flowing reservoirs.
Acanthocephalosis are helminthiases, the causative agents of which are acanthocephala (prickly-headed). The anterior end of the body of helminths is extended into a proboscis, usually armed with hooks. The following three types of acanthocephalans parasitizing humans are described. 1. Moniliformis moniliformis siciliensis. The male is 40-45 mm long, the female is 70-80 mm long. Eggs 0.085X0.045 mm in size. In the stage of puberty, it parasitizes in the intestines of mice and very rarely in humans; larvae were found in the darkling beetle.
2. Moniliformis m. moniliformis (Fig. 1). In the stage of сшфдшы it parasitizes in the intestines of rats and some other animals; described in humans. Intermediate hosts are the American cockroach and the darkling beetle. 3. Macracanthorhynchus hirudinaceus. The male is 100–150 mm long, the female 300–650 mm long (Fig. 2). At the stage of puberty, it parasitizes the intestines of pigs and some other mammals, very rarely in humans; larvae are found in May beetles.
