ABSTRACT
We report a case of systemic inflammatory response syndrome (SIRS) due to septicemia by Pasteurella multocida (P. multocida) who died three days after on admission. A few cases of septicemia by P. multocida were previously reported. In particular, capsular serotype analysis and somatic serotype analysis of P. multocida in human is very rare. Serotype A:3 P. multocida was identified in a diabetic patient with chronic obstructive pulmonary disease (COPD). There was high possibility that the isolate has been transmitted from an indoor companion dog since the patient had had close contact with the dog for one month. Here we discuss our case and 13 human cases of septicemia by P. multocida reported in Japan. Four cases from dogs and eleven cases from cats were included in these cases. The mortality rate of septicemia by P. multocida was 21.4% (3/14 cases). Two out of three cases died were diabetic.
