Erysipelas is a bacterial infection in pigs that is sometimes referred to as which skin condition?

• A. Diamond skin disease
• B. Blue eye disease
• C. Red skin syndrome
• D. Green skin disease

Answer: (A)

Diamond skin disease describes erysipelas in pigs because the infection creates distinctive diamond-shaped reddened patches on the skin, usually along the back and flanks. These diamond patterns arise from vascular damage and small clots caused by the bacteria Erysipelothrix rhusiopathiae. Besides the skin lesions, the disease can bring fever, lameness, and in chronic cases arthritis or vegetative endocarditis; the acute form can even cause sudden death. The nickname directly reflects the most recognizable sign, making it the best choice. Other labels don’t capture the characteristic diamond-shaped skin pattern. Vaccination and good management help prevent outbreaks.
