Abstract

Erysipelas of pigs (Erysipelothrix rhusiopathiae) is a widespread natural focal, septic, infectious disease, which occurs both acutely and chronically in the form of epizootic outbreaks. The microorganism is a stationary, straight or slightly curved stick of small size, gram-positive, not forming spores and capsules. At the moment, more than 10 strains and about 30 serotypes are known, more than 80% of the identified isolates belong to serovars 1 or 2, the microorganism is highly resistant to environmental factors and rotting, and specific serological identification of the pathogen is carried out using an agglutination reaction. Considering the problem in more detail, it can be noted that not everything is as simple as it seems at first glance, recently foreign colleagues have made much more progress in this issue than domestic ones. According to foreign literature, from 30% to 50% of pigs are carriers of a latent form of the disease. Erysipelas outbreaks can cause a high degree of morbidity and mortality within a few days, young animals are more susceptible to erysipelas, 3–12 months old, in the maintenance of which a large amount of financial and labor resources is invested.
