Abstract:
The most common pathogens associated with peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD) are gram-positive bacteria, which constitute 60 - 80% of all isolates. With the advancement of molecular technologies for bacterial identification, cases of CAPD-related peritonitis caused by bacteria previously not known to be associated with this clinical condition have been reported. Here we report the first case of CAPD-related peritonitis due to Laribacter hongkongensis.
Insights
Peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients is usually caused by gram-positive bacteria. This study reports the first known case of CAPD-related peritonitis caused by the bacterium Laribacter hongkongensis.
Area of Science:
- Microbiology
- Nephrology
- Infectious Diseases
Background:
- Gram-positive bacteria are the most frequent cause of peritonitis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD), accounting for 60-80% of cases.
- Advances in molecular identification techniques have revealed previously unrecognized bacterial causes of CAPD-related peritonitis.
- Laribacter hongkongensis is a bacterium not previously associated with this condition.
