Abstract
Pulsed-field gel electrophoresis (PFGE) has been used successfully to discriminate between strains of many different bacterial species. In this study, digestion of bacterial DNA with the restriction endonuclease NotI and PFGE were evaluated for the typing of isolates of Shigella dysenteriae type 1, an important cause of epidemic dysentery. There were 27 isolates from four outbreaks of dysentery, and 44 isolates from endemic dysentery cases and a laboratory culture collection. The epidemic isolates yielded two types each with two subtypes, whereas the endemic isolates and culture collection yielded eight types with numerous subtypes. These findings suggest that S. dysenteriae 1 can be typed by PFGE.Keywords
