Abstract:
We report a patient with chronic lung abscess due to Pasteurella multocida infection that may be caused by the contact with cows in his workplace. Despite its apparent rarity, chronic abscess due to P. multocida should be considered in the differential diagnosis of solitary pulmonary masses. This case report suggests that P. multocida infection can be potentially caused from saliva of cows as well as dogs or cats.
Insights
A chronic lung abscess caused by Pasteurella multocida infection, potentially linked to cow contact, highlights the need to consider this pathogen in lung mass diagnoses. This rare infection can stem from animal saliva, including cows, dogs, and cats.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Pulmonology
Background:
- Pasteurella multocida is a bacterium commonly found in the oral flora of domestic animals.
- Lung abscesses are typically associated with bacterial pneumonia, aspiration, or other predisposing factors.
- Chronic lung abscesses are uncommon and present diagnostic challenges.
Observation:
- A case of chronic lung abscess is presented in a patient with occupational exposure to cows.
- The patient's condition was attributed to Pasteurella multocida infection.
- The source of infection was suspected to be contact with cows in the workplace.
Findings:
- This case suggests Pasteurella multocida can cause chronic lung abscesses in humans.
- The infection may be acquired through direct contact with infected animal saliva.
- Pasteurella multocida should be included in the differential diagnosis for solitary pulmonary masses.
Implications:
- Healthcare providers should consider Pasteurella multocida in the differential diagnosis of chronic lung abscesses, especially in individuals with animal contact.
- Occupational exposure to livestock may pose a risk for zoonotic Pasteurella multocida infections.
- Further research is warranted to understand the epidemiology and transmission dynamics of Pasteurella multocida lung infections.
