What causes swine erysipelas?

What causes swine erysipelas?

Swine erysipelas is an infectious disease caused by the bacterium Erysipelothrix rhusiopathiae seen mainly in growing pigs and characterised clinically by sudden death, fever, skin lesions and arthritis. The fever can induce abortion in pregnant gilts and sows.

How does pigs erysipelas spread?

Swine erysipelas is caused by a bacterium, Erysipelothrix rhusiopathiae (syn, insidiosa) that is found in most if not all pig farms. Up to 50 percent of animals may carry it in their tonsils. It is always present in either the pig or in the environment because it is excreted via saliva, faeces or urine.

What is pseudorabies swine?

Pseudorabies (PRV) is a highly contagious infectious disease of swine caused by a herpes virus. As the only primary hosts, swine can contract the disease, recover, and remain carriers. Carrier animals with PRV do not shed the virus on a continual or daily basis.

What are the three main clinical forms of swine erysipelas?

Swine erysipelas caused by E. rhusiopathiae is seen in three forms: acute, subacute and chronic [10,11,33].

What causes red spots on pigs?

The Swine Pox virus is widespread and infects swine through skin abrasions, causing circular red lesions on the flank, abdomen, face and head (Taylor, 1995). It affects all age groups although it is unusual in piglets however there is evidence to suggest it is a congenital disease (Thibault et al., 1998).

What are the clinical signs of swine erysipelas?

Erysipelas in swine is caused primarily by Erysipelothrix rhusiopathiae and has acute, subacute, and chronic manifestations. Common clinical signs include characteristic diamond-shaped skin lesions, diffuse erythema, septicemia, and/or arthritis. Pigs are often healthy carriers of the bacterium.

What causes pseudorabies in swine?

Pseudorabies is a disease caused by the pseudorabies virus in the herpes family, which primarily affects swine but is occasionally transmitted from pigs to cattle, sheep, goats, dogs, cats, and wild animals. It is also known as Aujeszky’s disease and “mad itch.” Pseudorabies is not related to rabies.

Which body system does pseudorabies affect in pigs?

Pseudorabies (PRV) is a major viral disease manifested in swine by signs and lesions that vary among different age groups. The disease is characterized by three overlapping syndromes that reflect lesions in the central nervous system (CNS), respiratory system or reproductive system.

Is erysipelas contagious in pigs?

Is it contagious? The bacterium is excreted in saliva, faeces or urine so is easily passed from pig to pig, but it is also present in the environment, so a single pig can contract the disease without any contact with others.

What causes bumps on pigs?

Pigs can also become hypersensitive to the mites (usually 3-8 weeks after the initial infection) causing intense skin reactions of small red pimples covering their entire body.
