Aeromonas species in human septicaemia & diarrhoea
1Department of Microbiology, Christian Medical College Hospital, Vellore.
Abstract:
An increase was observed in the isolation of Aeromonas sp. from clinical specimens, especially faeces, from patients with diarrhoeal disease and blood cultures from patients with suspected septicaemias. The isolation rate from diarrhoeal patients was 0.2 per cent in 1978-79 and this increased to 5.0 per cent in 1986-87. It is noteworthy that 13 patients of septicaemia due to Aeromonas species were encountered, predominantly in adults with lowered resistance due to underlying disease states including chronic diseases of the liver and kidney.
Insights
Aeromonas species are increasingly isolated from patients with diarrhea and sepsis. This rise in Aeromonas infections highlights a growing concern in clinical settings, particularly for vulnerable patient groups.
Area of Science:
- Microbiology
- Clinical Medicine
- Infectious Diseases
Background:
- Aeromonas species are increasingly identified in clinical samples.
- This includes isolation from fecal samples of patients with diarrheal disease.
- Aeromonas species are also detected in blood cultures from patients with suspected bloodstream infections.
Purpose of the Study:
- To report the observed increase in Aeromonas species isolation.
- To highlight the clinical significance of Aeromonas in diarrheal disease and sepsis.
Main Methods:
- Retrospective analysis of clinical specimen data.
- Monitoring isolation rates of Aeromonas species over time.
Main Results:
- A significant increase in Aeromonas isolation from diarrheal patients was observed, rising from 0.2% in 1978-79 to 5.0% in 1986-87.
- Thirteen cases of Aeromonas-associated septicemia were identified.
- Septicemia cases predominantly occurred in adults with compromised immune systems due to underlying chronic conditions.
Conclusions:
- Aeromonas species represent a growing etiological agent in diarrheal disease and septicemia.
- Patients with underlying chronic diseases, particularly liver and kidney conditions, are at higher risk for Aeromonas-related sepsis.
