Myt is an acute infectious disease of horses, characterized by catarrhal-purulent inflammation of the mucous membrane of the nasal cavity and pharynx, as well as purulent inflammation of the submandibular lymph nodes.
Epizootological data
Young horses are affected, most often from 6 months to 5 years old. Cases of the disease in older horses are rare. The source of the infectious agent are sick and recovered animals, as well as healthy carriers of bacteria. Infection occurs most often by alimentary means, less often by airborne means. Predisposing factors are colds, transportation, poor conditions of detention, etc. Myt manifests itself sporadically or in the form of epizootic outbreaks. Usually, the mortality rate does not exceed 5%, however, under unfavorable factors, myt can spread quickly and in such cases the mortality rate reaches 30-70%.
Course and symptoms
The incubation period lasts 1-15 days. The disease can be acute or subacute. There are typical and atypical forms, sometimes there is a genital form of myta.
The typical form is characterized by high body temperature (40-41°C), decreased appetite, depression, rhinitis, mucopurulent nasal discharge, cough, inflammation of the submandibular lymph nodes with subsequent suppuration and opening. Breathing is rapid and wheezing. Many lymphatic vessels are involved in the process.
With the atypical form of myta, abscesses form in the lungs and other internal organs and lymph nodes, the temperature is constantly high, the animal is exhausted.
The abortive form is characterized by an increase in body temperature, rhinitis, a slight increase in the submandibular lymph nodes without suppuration. Recovery occurs after 5-7 days.
The genital form of mastitis is manifested by catarrhal-purulent inflammation of the vaginal mucosa, regional lymph nodes, and sometimes purulent mastitis. In stallions, it occurs as acute catarrhal-purulent inflammation of the glans penis and urethra.
Diagnosis of mastitis is based on epizootic data (mass cases of the disease in young horses), clinical signs (fever, rhinitis), the results of pathological examination and laboratory tests.
Treatment
Sick animals are immediately isolated in a separate dry, warm room without drafts. Abscesses are opened and wounds are treated. Antibiotics and sulfonamides are used.
Prevention and control measures
- To prevent mastitis, young animals must be provided with adequate feeding, kept in dry, well-ventilated stables, and given daily exercise;
- constantly protect foals from exposure to cold factors (drafts, drinking from cold water sources, staying in cold rain).
- To prevent possible introduction of the causative agent of myt, horses are brought in and forage is purchased only from farms that are free of this disease.
- All newly arrived horses are kept separately in preventive quarantine for 30 days.
- Disinfection of premises, walking areas - chemical disinfectants in normal concentrations have a detrimental effect on the pathogen.
