SPECIFIC FEATURES OF MOLECULAR EPIDEMIOLOGY OF IMPORTED MORBIDITY CAUSED BY SALMONELLA ENTERITIDIS INTRODUCED STRAINS WITH SPECIFIC PLASMID TYPES

Abstract

Aim. To compare the plasmid characteristics of Salmonella Enteritidis populations isolated from human patients in the Primorsky and Khabarovsk Territories to determine the causes and mechanisms of the morbidity gain associated with Salmonella infections caused by specific plasmid types. Materials and methods. The plasmid analysis of S. Enteritidis isolates from 7057 patients, including 6120 patients in the Primorsky Territory and 937 in the Khabarovsk Territory were performed over the period of 2006-2013. The plasmid profile was analyzed by the method of Kado C.I. and Liu S.T. (1981). Results. The concept of the synchronous morbidity among people living in different administrative territories caused by specific plasmid types of S. Enteritidis was established. The need to identify this type of morbidity is predicated on its targeted control and prevention measures. Conclusion. The nonintegrated epidemiological surveillance of salmonellosis covering certain administrative territories is unable to control the whole process of synchronous morbidity; additional infection control of strategies is needed.
