[Interhospital spread of Shigella flexneri 2A].
In this article the results of the study of regularities in the development of outbreak morbidity in shigellosis, caused by S.flexneri 2a, in hospitals are presented. The study was carried out with the use of the method of typing by the plasmid profile. The study showed the continuity of the epidemic process in the foci which appeared at intervals considerably exceeding the incubation period. The fact of the interhospital spread of S.flexneri 2a was established. The strain causing the disease was identified by the characteristic set of plasmids and their size. The possibility of reinfection of patients with S.flexneri 2a under hospital conditions was confirmed. The possibility of changes in the main transmission routes in the course of the spread of S.flexneri 2a infection in closed groups was pointed out.
