Abstract:
Pasteurella multocida is a gram-negative coccobacillus bacterium found as a commensal in the oropharynx of domestic animals such as cats and dogs and some farm animals. Soft tissue infections and occasionally bacteremia in immunocompromised patients with direct contact with animals are described. We report a 61 year old male with a history of scratches and close contact with domestic cats, with a septic shock originating from a pulmonary focus, requiring mechanical ventilation and vasopressors. Blood cultures disclosed the presence of Pasteurella multocida. He responded successfully to antimicrobials.
Insights
A cat scratch led to Pasteurella multocida septic shock in an immunocompromised man. Prompt antimicrobial treatment successfully resolved the severe infection.
Area of Science:
- Infectious Diseases
- Bacteriology
- Critical Care Medicine
Background:
- Pasteurella multocida, a Gram-negative coccobacillus, commonly inhabits the oropharynx of domestic animals.
- Infections typically manifest as soft tissue infections or bacteremia in immunocompromised individuals with animal contact.
Observation:
- A 61-year-old male with a history of cat scratches and close contact presented with septic shock.
- The septic shock originated from a pulmonary focus, necessitating mechanical ventilation and vasopressor support.
Findings:
- Blood cultures confirmed the presence of Pasteurella multocida.
- The patient showed a successful clinical response to antimicrobial therapy.
Implications:
- This case highlights the potential for severe Pasteurella multocida infections originating from animal contact.
- Early recognition and appropriate antimicrobial treatment are crucial for managing Pasteurella multocida-induced septic shock, particularly in immunocompromised patients.
