[Isolation of a rare serovar of Plesiomonas shigelloides]

The authors describe the isolation of a rare serovar Plesiomonas shigelloides from a patient with diarrhoea. The isolated strain belongs according to a combined Japanese-Czechoslovak antigenic scheme to serovar 024 H"o". The interesting finding draws attention to the possibility of routine departments to contribute to investigations of the incidence, importance and antigenic structure of this bacterial species.
