Juvenile pustular dermatitis

Superficial juvenile pustular dermatitis is superficial pyoderma of cats caused by Pasteurella multocida and various beta-hemolytic streptococci. No underlying cause has been identified[1]. Although P. multocida can cause infections to humans via bite wounds from cats, it primarily causes skin infections on cats.

Dermatological signs are characterised by non-follicular pustules associated with epidermal collarettes, mainly on the dorsum and trunk. Systemic signs are rare. P. multocida or beta-hemolytic streptococci may be isolated on bacterial culture. Histopathological examination of skin biopsies demonstrates the presence of non-follicular pustules containing lots of degenerate neutrophils.

Treatment involves giving a suitable antibiotic for about 3 weeks.
