Malignant catarrhal fever

Malignant catarrhal fever (coruza gangrenosa) is an acute infectious disease of cattle and buffaloes, characterized by croupous inflammation of the mucous membranes of the head, eye and nervous system damage.

Etiology. The causative agent of malignant catarrhal fever belongs to the family Gerpesviridae.

Epizootological data. The peculiarity of the infection is that the disease is not transmitted by direct contact. The main carrier of the pathogen are animals of other species (sheep), and cattle - an epizootic deadlock. Reinfestation occurs by aerogenic means, with feed, drinking water, and it happens only if there is an extracellular pathogen in the environment or biological secrets. In cattle, the virus is located inside epithelial cells and therefore no infection occurs between animals of this species.

The course and symptoms. Clinical signs: chills, increased general (up to 40-42 ° C) and local (at the base of the horns) temperature, increased thirst, appetite decreases, milk secretion stops, hair is disheveled, dry skin, lymph nodes are increased, trembling of certain muscle groups is observed, staggering gait, anxiety attacks; on the 2-3rd day - photophobia, lacrimation, eyelid swelling, purulent discharge from the eyes. With a complicated course of the disease - ulcers on the cornea.
The inflammatory process gradually captures the nasal, frontal and maxillary cavities; there is a cough, shortness of breath, difficulty swallowing. Sick animals die on the 4-10th day with acute (90-100% of animals) and on the 14-20th with subacute disease (50-90% of animals).

Diagnosis. The diagnosis is made on the basis of epizootological data, symptoms of the disease, pathological changes and laboratory research results. The virus is isolated on a bovine thyroid cell culture. In the blood, antibodies are determined using RAC, ELISA. Identification of the culture virus and the pathogen in the biological material (cell lysate, affected tissues, peripheral blood leukocytes) is carried out using PCR.

Differential diagnosis. Exclude plague, foot and mouth disease, rabies, viral diarrhea, spongiform encephalopathy of cattle.

Treatment. Specific treatment methods are not developed. Sick animals are isolated and treated with antibiotics, sulfa drugs, and they also apply methods of symptomatic therapy.

Prevention and control measures. No means of specific prophylaxis. For the eradication of the disease, general antiepizootic measures are used - restriction of livestock movement, disinfection, quarantine of sick animals.

    Infectious non-contagious disease of cattle and buffalo, characterized by persistent fever, croupous inflammation of the mucous membranes of the respiratory tract and the gastrointestinal tract, damage to the eyes and central nervous system. For catarrhal fever, except cattle (especially at a young age), buffaloes, goats, antelopes are susceptible
  3. Malignant phase of hypertension (malignant nephrosclerosis)
    Malignant nephrosclerosis is a kidney disease associated with the malignant or accelerated phase of hypertension. Hypertension of this type usually develops in previously normotensive patients, and also often in patients who have previously suffered from essential benign hypertension, secondary forms of hypertension or chronic renal diseases, especially glomerulonephritis and reflux

    At first glance, it seems strange that a disease that had killed many of its victims before may be a matter of teasing among those people who should fear it most. But it does not look strange if you understand that for people with self-destructive tendencies, the role of a popular joke is death. Blue Devils, or GD, is a psychosis that can occur after a long alcoholic
  5. Exudative-catarrhal diathesis
    Exudative-catarrhal diathesis is the ability of the hereditary congenital and acquired properties of the body to respond with an increased response of the skin and mucous membranes to individual external stimuli. Exudative-catarrhal diathesis is caused by genetic factors (genetic burden - in 70-80% of children), age characteristics of the enzyme system of the digestive tract and

    Acute inflammation of the larynx mucosa (laryngitis satarrhalis acuta) is often observed as an independent disease. Often it is a continuation of catarrhal inflammation of the mucous membrane of the nose, throat with a cold or acute catarrh of the upper respiratory tract, acute respiratory viral infection, flu; it may occur after voice overloads, inhalation of irritating
    Clinic: common symptoms indicate the beginning of an inflammatory infectious process in the form of CNS intoxication, cardiovascular system, etc. Radiological signs are less pronounced than with croupous pneumonia. Blood test: small leukocytosis up to 10 thousand with a small rod - nuclear shift, there is no toxic leukocyte granularity. Urine ECG - no change. Local symptoms speak of

    Chronic catarrhal endometritis refers to chronic inflammation of the mucous membrane of the uterus, characterized by a constant release of catarrhal exudate from the uterus. Etiology. Chronic catarrhal endometritis usually develops from acute endometritis, if the causes that caused it were not promptly resolved. In cows, chronic endometritis is most often the result of acute

    Exudative-catarrhal diathesis (EKD) is a constitutional feature of a child, in which there is a tendency to recurrent infiltrative-desquamatotic lesions of the skin and mucous membranes, the development of allergic reactions, prolonged inflammatory processes, lymphoid hyperplasia, and lability of water-salt metabolism.
