It is a superficial skin infection of pups and kittens characterized by small vesicles which lead to small pustules. Similar lesions are observed in the udder of cattle, buffalo and goat known as udder impetigo. Contagious pyodermatitis of pig is also similar disease.
Aetiology
This is caused by Streptococcus aureus.
Clinical Findings
Initially there is macule formation and then papules. This is followed by formation of thick walled vesicles, surrounded by zone of erythema. The vesicles ultimately turn into pustules. Honey coloured fluid is discharged from ruptured pustules. Finally the lesions are covered with scab.
On occasion, subcutaneous tissues are involved resulting to development of furuncles or boils.
Diagnosis
It is based on:
Characteristic clinical lesions on the skin.
Isolation and identification of causative organism from vesicular or pustular fluid through culture.
Treatment
There may be spontaneous regression of lesions.
Antiseptic solution or ointment may be applied.
Ancillary treatment include oral zinc therapy.
