Ruminant trichocephalosis

Ruminant trichocephalosis (trichocephalosis) is a nematodosis disease that occurs acutely or chronically with signs of depression, loss of appetite, emaciation, anemia, and disruption of the gastrointestinal tract.

Etiology. The causative agents of trichocephaliasis of animals are helminths of the genus Trichocephalus, which are parasitic 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, trichocephalus eggs reach the invasive stage in 2-3 weeks. When animals enter the body, larvae emerge from the eggs and develop into a sexually mature individual in 31-52 days.

Epizootology. Ruminant trichocephalosis is ubiquitous. Young animals are most susceptible. Infection of animals occurs mainly in the summer on pastures, indoors, in walking yards. Trichocephalus eggs are resistant to adverse factors.

Pathogenesis. Trichocephals with their head ends penetrate the mucosa of the large intestine, violate its integrity, inoculate pathogenic microflora. The function of the large intestine, liver is impaired, the composition of the blood changes.

Symptoms and course.
Depression, loss of appetite, anemia, exhaustion, pain in the abdomen are observed. Constipation alternates with diarrhea, in the feces they find blood.

Pathological changes. Exhaustion, catarrhal inflammation of the large intestine mucosa, ulcers, and liver dystrophy are detected.

Diagnosis. The intravital diagnosis is made by the detection of trichocephalus eggs in feces, the post-mortem diagnosis is by the detection of adult helminths in the large intestine.

Treatment. An effective department store is 0.0003 g / kg (in terms of DV), 1% rvertin is 0.02 g / kg, fenbendazole is 0.015 g / kg, albendazole is 0.01 g / kg, tetramisole is 0.01 g / kg two day in a row, pharmacin, aversect-2, ivomek - 1 ml per 50 kg of animal weight and other drugs.

Prevention Isolated young animals from adult animals. Deworming of animals before pasture on a pasture and when stalled. Compliance with feeding conditions and animal health requirements.

Ruminant trichocephalosis

  1. Trichocephalosis of pigs
    Trichocephalosis in pigs (trichocephalosis) is a nematodosis 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. Trichocephals are found mainly in the large intestine. Pigs become infected by swallowing invasive eggs
  2. Trichocephalosis
    Etiology, pathogenesis. The causative agent is a whipworm, parasitizing in the human large intestine. The life span of a whipworm parasite is about 5 years. A whipworm injures the intestinal mucosa and is a hematophagous, which contributes to the inoculation of microflora, whipworm causes reflex reactions in other organs of the abdominal cavity. Their metabolic products sensitize in the body. Clinic.
  3. Ruminant paramphistomatidoses
    Paramphistomatidoses (paramphistomatidoses) are trematodose diseases characterized by severe diarrhea, exhaustion, loss of appetite, edema, and disruption of the gastrointestinal tract. Cattle and small cattle, wild ruminants are sick. Etiology. The main causative agent of paramphistomatidoses of domestic ruminants in Belarus is Liorchis scotiae, however, in the southern and central zones
  4. Ruminant bunostomoses
    Bunostomosis (bunostomosis) is a ruminant nematode disease that occurs acutely or chronically with signs of emaciation, anemia, and gastrointestinal tract malfunction. Etiology. The causative agents are the nematodes Bunostomun phlebotomun and B. trigonocephalum of white color, 20-25 mm long. Representatives of the first species parasitize mainly the cattle in the small intestine, while the second
  5. Ruminant trichostrongilidoses
    Trichostrongylidoses of ruminants (trichostrongylidoses) are nematodous diseases that occur more often in a subclinical form with signs of exhaustion, anemia, and disorders of the gastrointestinal tract. Etiology. The causative agents of the disease are geohelminths, small nematodes from the Trichostrongylidae family: gemonkhs, trichostrongils, ostertagia, cooperia, nematodes, which are localized in the abomasum and
  6. Ruminant haberthiosis
    Habertiosis (chabertiosis) is a ruminant nematode disease with signs of anemia, loss of appetite, and emaciation. In lambs, cases are often noted. Etiology. The causative agent of haberthiosis is the nematode Chabertia ovina from this. Strongylidae, about 26 mm long, localized in the large intestine. The body develops from larva to adult helminth within 1-2 months and live in it for up to a year.
  7. Ruminant protostrongilidoses
    Protostrongilidoses (protostrongylidoses) - nematode diseases of small ruminants, manifested by emaciation, damage to the respiratory system, anemia. Etiology. The causative agents of protostrongilidoses are the strongylates of the Protostrongylidae family, among which mulleri (Mullerius capillaris), protostrongil (Protostrongylis kochi) and cystocaula (Cystocaulus nigrescens) are more common. it
  8. Monetiosis of ruminants
    Moniesioses (moniesioses) - cestodose diseases of ruminants (mainly young animals), occurring acutely or chronically with signs of decreased appetite, emaciation, diarrhea and nervous phenomena. Etiology. The causative agents are cestodes of the Anoplocephalidae family, of the genus Moniezia (M. expansa, M. benedeni). The length of the parasite is up to 1 m or more. The segments are short but wide. Hermaphroditic joints have two sets of

Fasciola gigantica (in all animals) The eggs are yellow-golden-yellow 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, at the opposite, more blunted, there may be a tubercle. Inside the yolk cells and

  11. Ruminant esophagostomoses
    Esophagostomoses (oesophagostomoses) are nematodous diseases that occur acutely or chronically and are characterized by a decrease in appetite, emaciation and impaired functioning 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, parasitizing in
  12. Ruminant dictation
    Dictyocaulesis (dictyocauleses) - nematodous diseases of animals that occur acutely or chronically with signs of decreased appetite, cough and emaciation. Etiology. The causative agents of the disease are helminths from the genus Dictyocaulus (D. filaria, D. viviparus). The first species, 30-100 mm long, parasitizes in the lungs of sheep, the second - 20-70 mm - in the lungs of calves. Epizootology. Invasive larvae of dictiocaul
  13. Anesthesia of small ruminants
    Premedication is optional. For anesthesia, a 5% solution of thiopental (pentotal) - sodium is used at the rate of 15 mg / kg of the animal's weight. The solution is injected into the saphenous vein of the forearm. The first quarter of the dose of the solution is administered quickly, and the remaining part is slowly, until complete anesthesia, which lasts 15-20 minutes. If anesthesia needs to be extended, another third of the dose is additionally injected.
