Abstract
We present the draft genome of Shewanella frigidimarina Ag06-30, a marine bacterium from King George Island, Antarctica, which encodes the carbapenemase SFP-1. The assembly contains 4,799,218 bp (G+C content 41.24%). This strain harbors several mobile genetic elements that provide insight into lateral gene transfer and bacterial plasticity and evolution.
Highlights
Shewanella spp. are Gram-negative bacteria with highly versatile respiration systems that thrive in aquatic niches under different environmental conditions; some species are opportunistic pathogens [1, 2]
We report the draft genome of Shewanella frigidimarina strain Ag06-30, which was isolated from intertidal seawater on a resting area of southern elephant seals (Mirounga leonina) on Potter Peninsula, King George Island (Isla 25 de Mayo), South Shetland Islands, Antarctica (62°15=22Љ S, 58°37=24Љ W)
Bacteria were grown on mineral basal media with 1.6% agar at 4°C
Summary
Shewanella spp. are Gram-negative bacteria with highly versatile respiration systems that thrive in aquatic niches under different environmental conditions; some species are opportunistic pathogens [1, 2]. Shewanella spp. have very plastic genomes as a result of the presence of several mobile genetic elements (MGE), which contribute strongly to bacterial evolution and adaptation [3]. Some Shewanella spp. encode OXA-48-type emerging carbapenemases, which have been transferred to multidrug resistant Enterobacteriaceae [4, 5]. Analyses of Shewanella genomes provide useful information on the evolution and adaptation of this organism to many niches and their participation in MGE and antimicrobial resistance gene transfer.
