Answer:
Domestic animal bites or scratches can produce acute cellulitis and
lymphangitis. These conditions frequently develop very rapidly and with
particular virulence. Cultures usually identify Pasturella multicocida
as the pathogen. The antibiotic of choice in treating this organism is
penicillin, but the cephalosporins are also effective. No bite should be
sutured primarily. If small or punctate, the wound may require extension.
Thorough debridement and irrigation should be undertaken, and the use of
a Waterpik has been recommended. The wound should be left open.
