Pasteurella multocida septicaemia in 2 Swedish patients

Area of Science:

• Infectious Diseases
• Microbiology
• Clinical Medicine

Background:

• Pasteurella multocida is a Gram-negative bacterium commonly found in animal respiratory tracts.
• Human infections with P. multocida usually manifest as localized cellulitis, often following animal bites or scratches.
• Septicemia (bloodstream infection) caused by P. multocida is an uncommon but serious clinical presentation.

Observation:

• Two distinct cases of P. multocida septicaemia occurred in patients within the same hospital ward over a seven-month period.
• Both patients presented with severe systemic infection, deviating from the usual clinical presentation.

Findings:

• The study highlights the rare occurrence of P. multocida septicaemia.
• The simultaneous admission of two such cases in the same ward suggests potential localized transmission or a shared environmental/epidemiological factor.
• Detailed clinical and microbiological data were collected for both patients.

Implications:

• This case series underscores the importance of considering P. multocida as a potential cause of septicaemia, even if rare.
• Further investigation into potential transmission routes and risk factors for severe P. multocida infections is warranted.
• Clinicians should maintain a high index of suspicion for P. multocida septicaemia in relevant patient populations.
