Data on the genome and proteome profiles of ciprofloxacin-resistant Acholeplasma laidlawii strains selected under different conditions in vitro

Acholeplasma laidlawii is widespread hypermutable bacteria (class Mollicutes) capable of infecting humans, animals, plants, which is the main contaminant of cell cultures and vaccine preparations. The mechanisms of the development of antimicrobial resistance of this bacterium are associated with the secretion of extracellular vesicles, which can mediate the lateral transfer of antibiotic resistance determinants. We compared the genome profiles of ciprofloxacin-resistant A.laidlawii strains PG8r1 (MIC 10 µg/ml) and PG8r3 (MIC 10 µg/ml) selected under different in vitro conditions - when ciprofloxacin-sensitive (MIC 0.5 µg/ml) A.laidlawii PG8B strain was cultured at increasing concentrations of ciprofloxacin in a broth medium alone, and with vesicles derived from the ciprofloxacin-resistant (MIC 20 µg/ml) A.laidlawii PG8R(10)c-2 strain, respectively. Genome profiles of PG8c-3 (obtained from a single colony of the strain PG8B) and PG8R(10)c-2 were analyzed too. Patterns of the quinolone target genes (gyrA, gyrB, parE, parC) containing in extracellular vesicles of PG8c-3, PG8R(10)c-2, PG8r1 and PG8r3 were determined. Genome sequencing was performed on the NextSeq Illumina platform. Search and annotation of single nucleotide polymorphisms were performed using Samtools and SnpEff, respectively. We also compared cellular proteomes of PG8c-3, PG8r1 and PG8r3. The cellular proteome profiles of the A. laidlawii strains were determined by two-dimensional gel electrophoresis and MALDI-TOF/TOF MS. This work presents data on single nucleotide polymorphisms (SNPs) found in the genomes of the ciprofloxacin-resistant strains selected under different in vitro conditions and proteins that were differentially expressed in the cells of ciprofloxacin-resistant strains selected under different conditions in vitro.
