Abstract:
Pasteurella multocida (P. multocida) is an immobile, anaerobic, Gram-negative coccobacillus fermenting bacterium. This pathogen is commonly prevalent in the upper airways of healthy pets, such as cats and dogs, but was also confirmed in domestic cattle, rabbits, pigs, birds, and various wild animals. Infection in humans occurs as a result of biting, scratching, or licking by animals and contact with nasopharyngeal secretions. Inflammation at the site of infection develops within the first day from the injury. It is usually confined to the skin and subcutaneous tissue but, in particular situations, may spread to other organs and manifest as a severe systemic infection. Careful history-taking and microbiological confirmation of the infection enable diagnosis and appropriate treatment. Any wound resulting from an animal bite should be disinfected. The preferred and highly effective treatment against local P. multocida infection is penicillin or its derivatives. The prognosis for P. multocida infections depends on the infected site and the patient's comorbidities.
Insights
Pasteurella multocida, a common pet bacterium, can infect humans through animal contact, causing localized or systemic inflammation. Penicillin is the preferred treatment for Pasteurella multocida infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Veterinary Medicine
Background:
- Pasteurella multocida (P. multocida) is a Gram-negative coccobacillus commonly found in animal respiratory tracts.
- Infections in humans typically result from animal bites, scratches, or licks, leading to inflammation.
Purpose of the Study:
- To summarize the characteristics, transmission, and treatment of Pasteurella multocida infections in humans.
Main Methods:
- Review of existing literature on P. multocida infections.
- Clinical case analysis of human infections.
- Microbiological diagnostic considerations.
- Treatment guidelines for P. multocida.
Main Results:
- P. multocida infections usually cause localized skin and subcutaneous inflammation but can lead to systemic disease.
- Diagnosis relies on patient history and microbiological confirmation.
- Penicillin or its derivatives are highly effective for local P. multocida infections.
Conclusions:
- Prompt disinfection of animal bite wounds is crucial.
- Treatment effectiveness and prognosis depend on infection site and patient health.
- Understanding P. multocida transmission is key for prevention.
