Аннотация

Цель. Выявить потенциально патогенных бактерий в планктоне солоноватых рек Приэльтонья методом высокопроизводительного секвенирования участка гена 16S рРНК. Материалы и методы. Образцы воды из солоноватых рек Ланцуг и Чернавка, впадающих в озеро Эльтон, отбирали в объеме 50 мл, фильтровали через мембранные фильтры с диаметром пор 0.22 мкм. Тотальную ДНК выделяли методом фенол-хлороформной экстракции с предварительной гомогенизацией и ферментативным лизисом. ДНК-библиотеки для секвенирования создавали по протоколу Illumina с праймерами к вариабельному участку V3-V4 гена 16S рРНК. Секвенирование проводили на платформе MiSeq («Illumina», США). Результаты. В планктонных образцах солоноватых рек Приэльтонья были обнаружены филотипы потенциально патогенных бактерий филума Proteobacteria из семейств Enterobacteriaceae, Pseudomonadaceae, Campylobacteraceae, Vibrionaceae, Aeromonadaceae, Moraxellaceae, Legionellaceae, Alcaligenaceae, Campylo-bacteraceae, а также филумов Firmicutes, Bacteroidetes, Actinobacteria. Вероятным источником бактериального загрязнения является крупный и мелкий рогатый скот. Заключение. Полученные данные демонстрируют, что солоноватые континентальные водоемы наряду с пресными и морскими выполняют резервуарную функцию для потенциально патогенных микроорганизмов. Высокопроизводительное секвенирование может быть использовано для скрининговой оценки присутствия патогенов в воде.

Abstract

Aim. To indicate potentially pathogenic bacteria in plankton of the brackish rivers flowing into the Elton Lake by high-throughput sequencing of 16S ssuRNA gene. Materials and methods. The water samples from brackish rivers Lantsug and Chernavka, flowing into the Elton Lake, were taken up in a volume of 50 ml, filtered through membrane filters (pore diameter - 0.22 pm). Total DNAwas obtained by phenol-chloroform extraction with preliminary homogenization and enzymatic lysis. DNA libraries for sequencing were created by protocol Illumina with primers to a variable V3-V4 region of 16S ssuRNA gene. Sequencing was performed on a platform MiSeq («Illumina», США). Results.There were found the phylotypes of potentially pathogenic bacteria of Proteobacteria phylum from the families Enterobacteriaceae, Pseudomonadaceae, Campylobacteraceae, Vibrionaceae, Aeromonadaceae, Moraxellaceae, Legionellaceae, Alcaligenaceae, Campylobacteraceae, and also of Firmicutes, Bacteroidetes, Actinobacteria phyla in the plankton samples of the brackish rivers. Probable source of bacterial contamination is large and small cattle. Conclusion. These data demonstrate that the continental brackish waters, along with freshwater and marine habitats perform a reservoir function to potentially pathogenic microorganisms. High-throughput sequencing can be used to screen the presence of pathogens in water.
