Pasteurella multocida is frequently part of the normal flora of the na
sopharynx and digestive tract of several wild and domestic animals. Al
though P. multocida can produce a variety of upper and lower respirato
ry tract infections, only four previous cases of tonsillitis caused by
this organism have been reported. We present a case of pasteurella to
nsillitis in a 30-year-old female who was exposed through her cat, whi
ch manifested upper respiratory symptoms.
