Diagnosis. Lice or their eggs are found in the hairline of animals.

Treatment. In winter, especially in horses, treatment is carried out: gas-chamber or disinsectalin, or hexachloran dusts. During the summer, subject to availability warm rooms and in winter, emulsions, liniments or solutions are used: 3-4% soap emulsion, 2% chlorophos solution, 0.25 creolin-based hexchlorane emulsion.

Infection occurs when sick people come into contact with healthy people. The disease is most common in winter.

Diagnosis. Detection of lice and lice when examining animals and birds is the basis for establishing a diagnosis for these diseases.

Treatment. With lice, the same remedies are used as with lice. Birds affected by the lice are treated with a nicochloran emulsion containing 0.3-0.4% of the hexachlorane gamma isomer. The treated bird is removed from the premises, the latter, after cleaning, is disinfected with insecticidal preparations

32 .ECHINOCOCCOSIS larvaceous in ruminants and pigs

A chronic disease, manifested by exhaustion, is diagnosed posthumously by detection in the liver, lungs, less often in other organs - the larvacyst of the cestode Echinococcus granulosus. Agricultural and wild animals and humans are sick. Man and agricultural animals are intermediate hosts, while dogs and wolves, foxes, arctic foxes are definitive. Lok-I liver, lungs, spleen, kidneys.

Pathogen: Echinococcus granulosis loci in the liver, lungs, sometimes in the brain, eyes and bones. Larvocysts - single or multiple water bubbles with a diameter of 1.5 - 15 cm. The wall of the bladder is made of elastic translucent whitish tissue. Through outer shell- nutrition; and the inner one forms scolexes and daughter bubbles and brood capsules (they can come off and swim freely in the liquid of the echinococcus bladder. Development cycle: definitive hosts >> mature segments capable of moving and secreting eggs, scattering them>> herbivores and omnivores swallow eggs and in their to-ke Oncospheres are released from the embryophore and migrate into the thickness of the intestinal wall>> into the blood >> organs and tissues.After 5 months, the oncospheres that have entered the organs form small vesicles of echinococcus (2-3 mm).They increase and become invasive after about 6 months.When eating dogs of parenchymal organs containing hydatids of echinococcus >> scolex stick to the mucous membrane and after 1.5 months the 1st segment reaches development.

wingless insects

Wingless insects 1) primary insects, Apterygota, forms of a primitive structure that do not have wings, and, moreover, such, relatively to which. there is no indication that they ever had them and then lost them; they are considered descendants of organisms that lack wings, namely centipedes. Their primitive structure is indicated by the complete absence or incomplete development of faceted eyes, the isolation of the tracheal bundles, and direct development; chewing jaws; many species have a body with uniform articulation and abdominal legs. The abdomen is equipped with long bristles or a jumping fork. The closest of them to the original forms are the species of the family. Campodeidae, with underdeveloped ventral legs. Not much higher fools, or springtails(see), Poduridae, and silverfish(see), Lepismidae. 2) Forms, cat. there is reason to assume a regressive development of wings, since either forms related to them are equipped with wings (bugs, lice, aphids), or one mouth of individuals (male black cockroaches, sexual individuals of ants and termites) is still in the form of winged forms.
