Whole-Genome Sequence of Multidrug-Resistant Escherichia coli Strains Isolated from Mice with Mastitis.

ABSTRACT: We sequenced the genomes of Escherichia coli isolates G2M6U and G6M1F, two multidrug-resistant strains that were isolated from mammary tissue and fecal samples, respectively, from mice with induced mastitis. The complete genomes of G2M6U and G6M1F consist of chromosomes of 4.4 Mbp and 4.6 Mbp, respectively.

Project description:The spread of carbapenem-resistant Escherichia coli and Klebsiella pneumoniae is a global concern. The management of infections caused by multidrug resistance (MDR) isolates poses substantial clinical challenges in both hospitals and communities. This study aimed to investigate the genetic characteristics and variations of MDR E. coli and K. pneumoniae isolates. Bacterial identification and antibiotic susceptibility testing against 19 antibiotics were performed by standard methods. Whole genome sequencing (WGS) was carried out on eight carbapenem-resistant isolates using an Illumina MiSeq platform. The assembled draft genomes were annotated, then sequences were blasted against antimicrobial resistance (AMR) genes database. WGS detected several resistance genes mediating the production of β-lactamases, including carbapenems and extended-spectrum β-lactamase genes as (blaOXA-1/-48, blaKPC-2/-29, blaCMY-4/-6, blaSHV-11/-12, blaTEM-1, blaCTX-M-15, blaOKP-B, blaACT and blaEC). Furthermore quinolone resistance including oqxA/oqxB, aac(6')-Ib-cr5, gyrA_D87N, gyrA_S83F, gyrA_S83L, parC_S80I, parE_S458A, parE_I355T, parC_S80I, and qnrB1. In addition to aminoglycoside modifying enzymes genes (aph(6)-Id, aph(3″)-Ib, aac(3)-IIa, aac(6')-Ib, aadA1, aadA2 and aadA5), trimethoprim-sulfamethoxazole (dfrA12/A14/A17 and sul1/sul2), tetracycline (tetA and tetB), fosfomycin (fosA and uhpT_E350Q) resistance genes, while other genes were detected conferring chloramphenicol (floR, catA2, and efflux pump cmIA5), macrolides resistance (mph(A) and erm(B), and quaternary ammonium efflux pump qacEdelta. Bleomycin and colistin resistance genes were detected as ble and pmrB_R256G, respectively. Comprehensive analysis of MDR strains provided by WGS detected variable antimicrobial resistance genes and their precise resistance mechanism. WGS is essential for control and prevention strategies to combat the growing threat of AMR and the implementation of multifaceted interventions are needed.
