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