Trichocephalosis of ruminants

Trichocephalosis of ruminants (trichocephalosis) is a nematode disease, acute or chronic, with signs of oppression, loss of appetite, emaciation, anemia, and disorders of the gastrointestinal tract.

Etiology. The causative agents of trichocephalosis of animals are helminths of the genus Trichocephalus, parasitizing in the large intestine, mainly in the cecum. Their length is 6-8 cm, the front end is thin, hairy, the back of the body is thickened. In the external environment, trichocephalic eggs reach the invasive stage in 2–3 weeks. When ingested by animals, the larvae emerge from the eggs and develop into the mature individual for 31-52 days.

Epizootology. Trichocephalosis of ruminants is widespread. The most susceptible young. Infection of animals occurs mainly in summer on pastures, in premises, on walking yards. Trichocephalus eggs are resistant to adverse factors.

Pathogenesis. Trichocephalus head ends penetrate into the mucous membrane of the large intestine, violate its integrity, inoculate pathogenic microflora. Function of a large intestine, a liver is broken, the structure of a blood changes.

Symptoms and course.
Observed depression, loss of appetite, anemia, exhaustion, pain in the abdomen. Constipation alternating with diarrhea, in the fecal masses detect blood.

Pathological changes. They reveal exhaustion, catarrhal inflammation of the mucous membrane of the large intestine, ulcers, and liver dystrophy.

Diagnosis. Lifetime diagnosis is made by detecting Trichocephal eggs in the feces, postmortem - by detecting adult worms in the large intestine.

Treatment. Universal is effective - 0.0003 g / kg (LW), rivertin 1% - 0.02 g / kg, fenbendazol - 0.015 g / kg, albendazole - 0.01 g / kg, tetramisole - 0.01 g / kg two day in a row, pharmacyn, averse-2, iwomek - 1 ml per 50 kg of animal mass and other preparations.

Prevention. Isolated content of young animals from adult animals. De-worming of animals before pasture on pasture and at setting on stall maintenance. Compliance with the conditions of feeding and animal health requirements of animals.

Trichocephalosis of ruminants

  1. Trichocephalosis of pigs
    Swine trichocephalosis (trichocephalosis) is a nematode disease that occurs more often chronically with signs of anemia, depression, and progressive emaciation. Etiology. The causative agent is the nematode Trichocephalus suis, the males of which have a length of 33-48 mm, the females - 38-53 mm. There are trichocephalus mainly in the large intestine. Pigs become infected by ingesting invasive eggs from which they leave.
  2. Trichocephalosis
    Etiology, pathogenesis. The causative agent - whipworm, parasitizes in the human large intestine. The lifespan of a claw parasite is about 5 years. The whipworm injures the intestinal mucosa and is hematophagous, which contributes to the inoculation of microflora, the whipworm causes reflex reactions in other organs of the abdominal cavity. The products of their exchange are sensitized in the body. Clinic.
  3. Paramptomatosis of ruminants
    Paramphistomatosis (paramphistomatidoses) - trematodozny diseases characterized by severe diarrhea, exhaustion, loss of appetite, edema, disruption of the gastrointestinal tract. Sick cattle and small cattle, wild ruminants. Etiology. The main causative agent of paramptomatosis of domestic ruminants in Belarus is Liorchis scotiae, but in the southern and central zones
  4. Rinse bustonamoza
    Bunostomosis (bunostomosis) - nematodeotic diseases of ruminants, occurring acutely or chronically with signs of emaciation, anemia and disorders of the gastrointestinal tract. Etiology. The causative agents are the nematodes Bunostomun phlebotomun and B. trigonocephalum in white, 20-25 mm long. Representatives of the first species parasitize mainly small cattle in the small intestine, the second species in
  5. Trichostrongidosis ruminants
    Trichostrongidosis of ruminants (trichostrongylidoses) - nematodosis diseases occurring more often in a subclinical form with signs of exhaustion, anemia, disorders of the gastrointestinal tract. Etiology. Disease pathogens are geohelminths of small nematodes from the Trichostrongylidae family: hemonchae, trichostrongyls, ostertags, cooperias, nematodirs, which are localized in the abomasum and
  6. Habertiosis ruminants
    Chabertiosis (chabertiosis) is a nematode disease of ruminants with signs of anemia, loss of appetite, emaciation. Lambs often mark cases. Etiology. The causative agent of habertiosis is the nematode Chabertia ovina from this family. Strongylidae about 26 mm long, localized in the large intestine. In the body they develop from larva to adult helminth within 1-2 months and live in it for up to a year.
  7. Ruminant protostrongilosis
    Protostrongilosis (protostrongylidoses) - nematode diseases of small ruminants, manifested by emaciation, damage to the respiratory system, anemia. Etiology. Pathogens of the Protostrongylidae family are the causative agents of protostrongylidosis, among which are the most common mullaria (Mullerius capillaris), the protostrongyl (Protostrongylis kochi) and cystocaules (Cystocaulus nigrescens). it
  8. Moniesiosis ruminants
    Moniesiosis (moniesioses) - cestodose diseases of ruminants (predominantly young), occurring acutely or chronically with signs of loss of appetite, emaciation, diarrhea and nervous phenomena. Etiology. The causative agents are cestodes of the family Anoplocephalidae, of the genus Moniezia (M. expansa, M. benedeni). The length of the parasite to 1 m or more. Segments short, but wide. Hermaphroditic segments have two sets each.

Fasciola gigantica (in all animals) Eggs are yellow-gold or yellow-brown, large - 0.125—0.157 x 0.06 - 0.07 mm. The shell is smooth, thin. The sides are convex. At one pole there is a cap, on the opposite, more dulled, there may be a hillock. Inside the yolk cells and

  11. Esophagostomosis of ruminants
    Esophagostomoses (oesophagostomoses) are nematode diseases that occur acutely or chronically and are characterized by a decrease in appetite, emaciation and disruption of the gastrointestinal tract. Etiology. The causative agents are geohelminths from the genus Oesophagostomum, in sheep — O. venulosum and O. columbianum, in cattle — O. radiatum. These are thick white nematodes up to 20 mm long, parasitic in
  12. Dictiocauleses of ruminants
    Dictyokaulezy (dictyocauleses) - nematode diseases of animals, occurring acutely or chronically with signs of loss of appetite, cough and emaciation. Etiology. Helminths of the genus Dictyocaulus are the causative agents of the disease (D. filaria, D. viviparus). The first species with a length of 30-100 mm parasitizes in the lungs of sheep, the second - 20-70 mm in the lungs of calves. Epizootology. Dictyocaul invasive larvae
  13. Narcosis of small ruminants
    Premedication is not required. For anesthesia, a 5% solution of thiopental (pentothal) - sodium is used at the rate of 15 mg / kg of animal weight. The solution is injected into the saphenous vein of the forearm. The first quarter of the solution is injected quickly, and the rest slowly, before the onset of full anesthesia, which lasts 15–20 minutes. If the anesthesia needs to be extended, an additional third part of the dose is injected.
