Plesiomonas shigelloides : an extremely rare cause of Spontaneous Bacterial Peritonitis
Abstract:
Plesiomonas shigelloides, a rare cause of gastroenteritis in humans, is a gram negative rod belonging to the Enterobacteriaceae family. In addition, it has also been implicated in extra-intestinal infection, but prevalence data on such infections have been limited to case reports. To date there has been only one published case of P. shigelloides causing spontaneous bacterial peritonitis (SBP). We describe another patient with P. shigelloides SBP and compare our findings with those from the original case.
Insights
Plesiomonas shigelloides, a rare cause of gastroenteritis, can lead to spontaneous bacterial peritonitis (SBP). This report details a second case of P. shigelloides SBP, offering new insights into this uncommon infection.
Area of Science:
- Microbiology
- Infectious Diseases
Background:
- Plesiomonas shigelloides is a gram-negative bacterium, part of the Enterobacteriaceae family, known to cause gastroenteritis.
- Extra-intestinal infections by P. shigelloides are infrequently reported, with limited prevalence data.
- Spontaneous bacterial peritonitis (SBP) is a rare extra-intestinal manifestation of P. shigelloides infection.
Observation:
- This study presents a second documented case of spontaneous bacterial peritonitis (SBP) caused by Plesiomonas shigelloides.
- The clinical presentation and microbiological findings of this case are compared with the sole previously reported instance of P. shigelloides SBP.
Findings:
- Plesiomonas shigelloides can cause spontaneous bacterial peritonitis (SBP) in humans.
- The comparison of findings may elucidate patterns or risk factors associated with this rare infection.
Implications:
- This case contributes to the limited body of knowledge on Plesiomonas shigelloides as a cause of SBP.
- Further research is warranted to understand the epidemiology and clinical significance of P. shigelloides-associated SBP.
