Abstract:
The clinical course of a malnourished alcoholic in which Neisseria meningitidis was isolated from the blood and Moraxella osloensis from the peritoneal fluid is described. Following bacteriologic diagnosis, the patient was treated and responded to a course of penicillin therapy. To our knowledge, this represents the first case of peritonitis associated with M. osloensis. Clinical reports of the isolation of this organism are rare; its pathogenicity is not clearly established, and the presence of the organism may often be unrecognized.
Insights
This case study details a malnourished alcoholic patient with a rare Moraxella osloensis peritonitis infection. The patient successfully responded to penicillin therapy, highlighting a potential new clinical finding for this organism.
Area of Science:
- Infectious Diseases
- Microbiology
- Clinical Medicine
Background:
- Alcoholism and malnutrition can predispose individuals to infections.
- Neisseria meningitidis and Moraxella osloensis are bacteria that can cause human infections.
- Peritonitis is inflammation of the peritoneum, often due to infection.
Observation:
- A clinical case involving a malnourished alcoholic patient is presented.
- Neisseria meningitidis was identified in the patient's blood.
- Moraxella osloensis was isolated from the patient's peritoneal fluid.
Findings:
- The patient received penicillin therapy following bacteriologic diagnosis.
- The patient showed a positive response to the penicillin treatment.
- This case represents the first reported instance of peritonitis associated with Moraxella osloensis.
Implications:
- The pathogenicity of Moraxella osloensis requires further investigation.
- Clinical recognition of Moraxella osloensis infections may be challenging.
- This finding expands the known spectrum of Moraxella osloensis-related diseases.
