[The importance of serotyping Plesiomonas shigelloides]
1Státní zdravotní ústav, Praha.
Abstract:
The author presents an account of serovars of 432 strains of Plesiomonas shigelloides from various countries and sources; in addition to strains from man and animals also environmental strains. The most frequent serovars are O17 with three H antigens (H2, H11, H34) except for immobile strains, also O32:H4 and non-motile strains, O2:H1a1c and O44:H8. The other serovars did not reach the number of 10 strains, some serovars were found only one strain of each. Serovar O18:H2 was isolated in the course of 30 years only from cats and lynx and once from a pond in the FRG. As regards the distribution of different serovars, e.g. O68:H2 was found only in one district, while strains of the serogroup O17 come from various countries in the world. Between findings of the same serovar sometimes a 20-30-year interval elapses.
Insights
This study details Plesiomonas shigelloides serovars from diverse global sources, identifying O17, O32, O2, and O44 as the most common. Findings highlight the varied distribution and long-term isolation of specific serovars.
Area of Science:
- Microbiology
- Bacteriology
Context:
- Plesiomonas shigelloides is an emerging pathogen with diverse serovars.
- Understanding serovar distribution is crucial for epidemiology and public health.
Purpose:
- To catalog and analyze the serovars of 432 Plesiomonas shigelloides strains.
- To investigate the geographical and host distribution of identified serovars.
Summary:
- Analysis of 432 Plesiomonas shigelloides strains revealed common serovars including O17 (with H2, H11, H34 antigens), O32:H4, O2:H1a1c, and O44:H8.
- Less frequent serovars were identified, with some isolated only once.
- Serovar O18:H2 showed a 30-year isolation history from felines and a German pond, while O17 strains were globally distributed.
Impact:
- Provides a comprehensive overview of Plesiomonas shigelloides serovar diversity.
- Informs future research on the pathogenicity and transmission of specific serovars.
- Contributes to epidemiological surveillance and risk assessment of Plesiomonas shigelloides infections.
