Capnocytophaga: a review of the literature
The American Journal of Medical Technology
|August 1, 1983
Abstract:
Capnocytophaga species are normal mouth flora but can be opportunistic pathogens causing juvenile peridontitis and bacteremia in the compromised host. Indole-negative fusiforms isolated anaerobically or in the presence of increased CO2 can presumptively be identified as Capnocytophaga species.
Insights
Capnocytophaga bacteria, normally in the mouth, can cause infections like juvenile periodontitis and bacteremia in vulnerable individuals. Identifying indole-negative fusiforms under specific conditions aids in their presumptive diagnosis.
Area of Science:
- Microbiology
- Oral Health
- Infectious Diseases
Background:
- Capnocytophaga species are commensal bacteria residing in the oral cavity.
- These bacteria can act as opportunistic pathogens, particularly in immunocompromised individuals.
- Infections associated with Capnocytophaga include juvenile periodontitis and bacteremia.
Purpose of the Study:
- To highlight the pathogenic potential of Capnocytophaga species.
- To describe a presumptive method for identifying Capnocytophaga species based on their morphology and biochemical characteristics.
Main Methods:
- Isolation of fusiform bacteria under anaerobic or increased CO2 conditions.
- Assessment of indole production as a key differentiating test.
Main Results:
- Indole-negative fusiform bacteria isolated under the specified conditions are likely Capnocytophaga species.
- This finding aids in the presumptive identification of these opportunistic pathogens.
Conclusions:
- Capnocytophaga species represent a significant opportunistic pathogen in dentistry and medicine.
- The described method provides a practical approach for the presumptive identification of Capnocytophaga in clinical laboratories.
