New Delhi metallo-β-lactamase-1-producing <i>Citrobacter portucalensis</i> belonging to the novel ST264 causing fatal sepsis in a vulnerable migratory sea turtle.

"to date there are only two c portucalensis strains (tv06 and ectv13) producing esbls isolated from green sea turtles ( chelonia mydas ) in brazil [ ] which are available in the ncbi database (assembly accession numbers: gca_008370135 1 and gca_008370125 1); whereas no c portucalensis strains have been identified in human hosts in this country so far.; on the other hand data from 4 environmental c portucalensis strains (tk288 ek291 ec_47 and ec_49) isolated from water samples of beaches and the electronic waste dumpsite in nigeria were also included (assembly accession numbers: gca_023910405 1 gca_023910465 1 gca_019584605 1 and gca_019584545 1).; this whole genome shotgun project has been deposited at ddbj/ena/genbank under the accession jaecze000000000 1."
