The assembled genome of Colistin-resistant E. coli MRSN 388634 is now available in PATRIC here. Sequence reads for MRSN388634 have been deposited in the NCBI Short Read Archive by researchers at the Walter Reed Army Institute of Research and Walter Reed National Military Medical Center under Accession number SRP075674. The authors report the presence of mcr-1 in an E. coli cultured from a patient with a urinary tract infection in the United States. The early version of the publication can be found at “http://aac.asm.org/content/early/2016/05/25/AAC.01103-16.full.pdf”. A provisional assembly and annotation is provided in PATRIC using the PATRIC Genome Assembly and Genome Annotation services and can be accessed here. We will provide the GenBank version of the assembly once the genome becomes available in GenBank. We would like to thank the members of the Walter Reed team for their early release of the data in the Short Read Archive.
