Roundworms.



Roundworms. Morphology and anatomy. Some features of the nutrition and metabolism of nematodes. Reproduction and life cycles.

Parasitic roundworms are causative agents of many dangerous diseases (nematodes) in humans and domestic animals. The economic damage caused by nematodes in agriculture is very large. They pose a serious threat to human health.

Nematodoses. Ascaridosis (Ascaris lumbricoides). Enterobiosis (Enterobius vermicularis). Ankylostomidoses (Ancylostoma duodenale, Necator americanus). Strongyloidosis (Strongyloides stercoralis). Filariasis (neg. Filariata). Trichinosis (Trichinella spiralis). Pathogens. Features of their structure. The final and intermediate hosts. Epidemiology. Spread. The main foci in the Russian Federation. Ways to defeat a person.

Roundworms.

  1. Suspension of the uterus by the round ligaments
    Uterus ventrosuspension (ligamentoventrosuspensio uteri) is part of the complex of operations used for prolapse and prolapse of the genital organs. It is also used to correct uterine motility or fixed retrograde There are a number of methods for uterine ventilation: Dzhilliam — Kiparsky, Dartig — Webster, Doleri — Dzhilliam, Menges, Menges — Kozinsky, and others (Fig. 77). {foto120} Figure 77.
  2. Tapeworms.
    Morphology and anatomy of cestodes. Features of nutrition and metabolism of cestodes. Reproduction and life cycles of tapeworms. Hypothesis of poly - and monozoicity of cestodes. Human cestodoses. Many tapeworms cause serious and sometimes life-threatening diseases for their host. In some cases, the most pathogenic are sexually mature worms that parasitize the intestines, in others -
  3. Vladimir Filatov: plastic on a round stem
    Vladimir Petrovich Filatov (1875-1956) was a major ophthalmologist, one of the luminaries of this branch of medicine in the 20th century. However, in many scientific studies, he "stepped over" the scope of this specialty, enriched medical science and practice with major discoveries and achievements. Filatov made a particularly significant contribution to the development of surgery. Filatov received a medical diploma from Moscow University in 1897,

  7. Class of tapeworms (Cestoda)
    About 1800 species of tapeworms are known. All representatives of this class are endoparasites living in a sexually mature form in the intestines of humans and animals. The cestode body is flattened in the dorso-ventral direction and has the appearance of a tape. Body sizes vary greatly - from 1 mm to 10-18 m in length. At the front end of the body is the head (scolex), which carries the fixing organs - suckers, proboscis with hooks,
  8. LECTURE No. 15. Helminthiasis in children. Clinic, diagnosis, treatment, prevention
    Helminthiasis - a disease that develops when localized in the body of parasitic helminth worms and their larvae. Classification of helminthiases: 1) on the biological principle: nematodoses (roundworms), cestodoses (tape), trematodoses (flukes); 2) according to the epidemiological: geohelminthoses, biohelminthoses,
  9. Helminthiasis and their prevention
    Helminthiasis is a disease caused by parasitic organisms - helminths (worms). In total, about 250 types of helminths are known that can infect (infect) humans. They belong to two types of wildlife: flatworms (Plathelmintes) - include the class of tapeworms (cestodes) and the class of flukes (trematodes); roundworms (Nemathelmintes). The largest helminths are significantly
  10. Helminthic diseases
    Helminthic diseases (helminthiases) occur in humans as a result of damage to the body by worms (helminths), whose eggs or larvae came from food prepared in violation of sanitary rules. Worms are the simplest worms that parasitize in various organs and tissues of a person. They come in different shapes (round, flat, ring-shaped) and sizes (from a few millimeters to several meters).
  11. CHOICE OF ANTIHELMINTIC CHEMICAL DRUGS
    Helminthiasis - a group of diseases (invasions) caused by parasitic worms - helminths. Helminths parasitizing in humans belong to two types: roundworms - Nemathelminthes (class Nematoda) and flatworms - Plathelminthes. The latter is divided into two classes: tapeworms (Cestoidea) and flukes (Trematoda). When choosing a remedy for specific treatment of patients with helminth infections

  13. Helminthiases
    Helminthiasis is a widespread disease of cats caused by parasitic worms, among which the most common are nematodes or roundworms, trematodes (flat flukes, flukes) and cestodes (tapeworms). Diseases are characterized by a chronic course leading to depletion of the body and a decrease in natural resistance. Some helminths are capable of
