Summary
Most Plesiomonas shigelloides strains belong to common O serovars like O17. Their widespread, seemingly sporadic distribution suggests current detection methods may miss many circulating strains.
Area of Science:
- Microbiology
- Bacteriology
- Public Health
Background:
- Plesiomonas shigelloides is an opportunistic pathogen.
- Understanding its serovar diversity is crucial for epidemiological surveillance.
Purpose of the Study:
- To characterize the O serovar distribution of Plesiomonas shigelloides strains.
- To assess the geographical distribution of identified serovars.
Main Methods:
- Serotyping of 391 Plesiomonas shigelloides isolates.
- Analysis of O serovar frequency and geographical origin.
Main Results:
- 330 of 391 strains were typable into 43 O serovars.
- O17 (23%), O32 (7%), and O12 (4.5%) were the most common serovars.
- Most serovars were found sporadically across Europe, Asia, and America; O68 was repeatedly isolated in one Czech district.
Conclusions:
- Plesiomonas shigelloides exhibits significant O serovar diversity.
- The observed sporadic distribution may be an artifact of under-detection due to cultivation methods.
- Further research is needed to improve detection and understand true prevalence.
