Abstract

Ralstonia insidiosa is an opportunistic pathogen and a strong biofilm producer. Here, we present the complete genome sequences of R. insidiosa FC1138 and ATCC 49129. Both strains have two circular chromosomes of approximately 3.9 and 1.9 Mb and a 50-kb plasmid. ATCC 49129 also possesses a megaplasmid of approximately 318 kb.

Highlights

  • Ralstonia insidiosa is a Gram-negative, nonfermentative, aerobic bacillus, along with the closely related better-known species Ralstonia pickettii, widely present in aqueous environments, including municipal water and medical water purification systems [1,2,3]

  • Only eight fully assembled genomes of Ralstonia are available in the NCBI database, which do not include any from R. insidiosa

  • We present the complete and annotated genome sequences of R. insidiosa FC1138 and type strain ATCC 49129

Summary

Introduction

Ralstonia insidiosa is a Gram-negative, nonfermentative, aerobic bacillus, along with the closely related better-known species Ralstonia pickettii, widely present in aqueous environments, including municipal water and medical water purification systems [1,2,3]. Ralstonia insidiosa FC1138 was isolated from a fresh-cut produce-processing plant and determined to be a strong biofilm producer [6] that can promote biofilm formation by Escherichia coli O157:H7 [7] and other foodborne pathogens in dual-species biofilms. Only eight fully assembled genomes of Ralstonia are available in the NCBI database (http://www.ncbi.nlm.nih.gov/genome/), which do not include any from R. insidiosa. We present the complete and annotated genome sequences of R. insidiosa FC1138 and type strain ATCC 49129.
