[A clinical study on patients detected Pasteurella multocida from sputum]
Summary
Pasteurella multocida infections are increasing, often affecting patients with underlying lung disease or compromised immunity. Cats are a significant reservoir for this bacterium, posing an infection risk.
Area of Science:
- Medical Microbiology
- Infectious Diseases
Context:
- Pasteurella multocida is an opportunistic pathogen.
- An increasing incidence of P. multocida infections has been observed.
- Patients with underlying pulmonary conditions are frequently affected.
Purpose:
- To report on cases of P. multocida infection.
- To identify risk factors and potential sources of infection.
- To assess antibiotic susceptibility.
Summary:
- Ten cases of P. multocida sputum-positive infections were identified between 1990-2000, with a notable increase in the subsequent eleven years.
- The majority of patients (70%) had pre-existing pulmonary diseases like inactive tuberculosis or bronchiectasis.
- Compromised hosts included elderly individuals, steroid-dependent patients, and those with diabetes mellitus.
- P. multocida isolates were generally susceptible to penicillin and cephalosporins, though some erythromycin resistance was noted.
- Oral cavities of cats in two cases yielded P. multocida, with an 85% prevalence in the surveyed cat population, indicating cats as a reservoir.
Impact:
- Highlights the growing threat of P. multocida in clinical settings.
- Identifies high-risk patient populations for targeted prevention.
- Underscores the role of domestic animals, particularly cats, in pathogen transmission.
- Provides insights into antibiotic resistance patterns for treatment guidance.
