Category:Bacterial Myositis

Myositis = inflammation of muscle

Bacterial myositis occurs when bacteria gain entry via direct penetration, blood stream or extension from other areas. Lesions caused tend to be suppurative, serosanguinous or granulomatous.

Abscesses:

They are caused by pyogenic bacteria, usually: Arcanobacterium pyogenes in sheep and cattle, Streptococcus equi in horses, Corynebacterium pseudotuberculosis in sheep and goats. Pasteurella multocida causes cellulitis in cats.

Abscesses usually present with localised suppuration and necrosis of myofibres, they may occasionally spread via the fascia.
