About the Results of Monitoring Researches of Ballast Waters and Data of Identification of the Vibrioes Strains Selected During the Ships Researches in Russian Seaports in 2018

Abstract

Relevance. In September, 2017 the International Convention on Control of Ships’ Ballast Waters and sediments, in which the Russian Federation takes part, came into effect.Aim of article is to cover the results of implementation of the Convention in Russia, regarding selection and analysis of ballast waters tests for compliance with the international standard.Material and methods. The materials for work were data on ship arrivals at the international seaports of the Russian Federation, provided by sanitary and quarantine departments of the Russian ports, and monitoring researches of ballast waters in seaports of some regions of the Russian Federation. Analytical, bacteriological, molecular methods were applied.Results. The studies of ballast waters in the Leningrad and Kaliningrad regions have been conducted for the first time in 2018, and in the Rostov region the study lasts since 2010. The laboratory researches of ships’ ballast showed that E. coli, Enterococcus spp. were in norm, V. cholerae O1 and O139 in ballast were absent. 12 of 21 ballast water tests investigated by specialists of the Rostov region laboratories contained V. cholerae non-O1/non-O139, ballast was taken on the ships which arrived from Romania and Turkey.Сonclusion. The results of the molecular and genetic researches suggest that there is a probability of V. сholeraе introduction brougth with ship ballast. Management decisions are demanded to ensure biological safety of shipping and to decrease intestinal infections incidence in residents of the seaside cities.
