Swine erysipelas

Swine erysipelas is a bacterial infection that primarily affects pigs, but can also infect other animals and humans. It is caused by the bacterium Erysipelothrix rhusiopathiae.

Overview

Swine erysipelas is a common and economically significant disease in the pig industry, causing significant losses due to mortality, reduced growth rates, and decreased reproductive performance. The disease is found worldwide and can affect pigs of all ages, although it is most common in growing pigs.

Causes

The causative agent of swine erysipelas is Erysipelothrix rhusiopathiae, a Gram-positive, rod-shaped bacterium. The bacterium is found in the environment and can survive for long periods in soil and water. Pigs can become infected through ingestion or through skin wounds.

Symptoms

The symptoms of swine erysipelas can vary depending on the form of the disease. In the acute form, pigs may show signs of high fever, loss of appetite, and sudden death. In the chronic form, pigs may develop arthritis, skin lesions, and heart problems.

Prevention and Control

Prevention and control of swine erysipelas primarily involve vaccination and good biosecurity practices. Vaccines are available and are effective in preventing the disease. Biosecurity measures such as regular cleaning and disinfection, controlling rodent populations, and avoiding the introduction of new animals into the herd can also help prevent the spread of the disease.

Treatment

Treatment for swine erysipelas typically involves the use of antibiotics. Early treatment is important to prevent the development of chronic disease and to reduce the risk of spreading the infection to other animals.
