Abstract:

Pasteurellosis is a popular zoonotic infection with animal bite or scratch. We reported six non-Bite/ Scratch (B/S) infection including pneumonia (3), skin and soft tissue infection (2), and bacteremia (1). P. multocida was identified using MALDI-TOF mass spectrometry in all six non-B/S infections, while identification kits were used in 13 of 14 patients with B/S infections. Pneumonia occurred in two patients with underlying pulmonary disease, whereas ventilator associated pneumonia was developed in remaining one patient with cerebral infarction. P. multocida was isolated form blood specimen in patient with liver cirrhosis (Child-Pugh C) and diabetes. A patient with diabetes and normal pressure hydrocephalus who had toe injury with a fall and a patient with diabetes foot ulcer had cellulitis. Three of six patients with non-B/S infections did not have a pet, and there was no episode of recent animal contact. Non-B/S infections could be developed in patients with chronic pulmonary disease, those with open wound or immunocompromised hosts irrespective of the apparent animal exposure. Different from B/S infections, non-B/S infections by P. multocida should be assumed as opportunistic infections.
