DNA microarray-based identification of genes associated with glycopeptide resistance in Staphylococcus aureus.
The study identifies 17 genes associated with glycopeptide resistance in Staphylococcus aureus, including 8 novel genes. Overexpression of these genes, particularly graF and msrA2, significantly increases resistance to vancomycin, teicoplanin, and oxacillin.
Different bacterial gene expression patterns and attenuated host immune responses are associated with the evolution of low-level vancomycin resistance during persistent methicillin-resistant Staphylococcus aureus bacteraemia.
The study identifies transcriptional changes in Staphylococcus aureus associated with low-level vancomycin resistance, including down-regulation of spa and up-regulation of capsular polysaccharide biosynthesis genes and ureA.
Whole genome sequence and comparative genome analyses of multi-resistant Staphylococcus warneri GD01 isolated from a diseased pig in China.
The study identified 19 AMR genes in S. warneri GD01, including efflux pumps and target modifications, contributing to resistance against multiple antibiotics such as penicillin, amoxicillin, ampicillin, cefalexin, vancomycin, and sulfisoxazole.
Characterization of methicillin-resistant Staphylococcus aureus through genomics approach.
The study characterized methicillin-resistant Staphylococcus aureus (MRSA) isolates, identifying genes such as mecA, blaZ, norA, gyrA, gyrB, tet-38, mepA, mepR, arlS, arlR, mgrA, clsA, dfrC, msbA, rpoB32, mprF, and mrpA, which confer resistance to various antibiotics.
Genomic analysis revealed a novel genotype of methicillin-susceptible Staphylococcus aureus isolated from a fatal sepsis case in dengue patient.
The study identified a novel genotype of methicillin-susceptible Staphylococcus aureus (HS-MSSA) that caused a fatal sepsis case. The strain carries a strain-specific blaZ-bearing plasmid, indicating resistance to penam antibiotics.
Phenotypic and Genomic Profiling of Staphylococcus argenteus in Canada and the United States and Recommendations for Clinical Result Reporting.
The study characterizes the antimicrobial resistance genes and mutations in Staphylococcus argenteus isolates from North America, highlighting the presence of mecA, mgrA, arlR, mepR, blaZ, fosB, lmrS, and aac(6')-Ie-APH(2')-Ia, which confer resistance to various antibiotics.
Prevalence and antimicrobial resistance profiling of Staphylococcus aureus isolated from traditional cheese in Yunnan, China.
The study identified 18 antimicrobial resistance genes in Staphylococcus aureus strain DC.RB_015, including mecA, blaZ, mepA, tet(K), tet(38), arlR, arlS, norA, mgrA, LmrS, APH(3′)-IIIa, aad(6), ErmB, SAT-4, mecR1, GlpT, murA, and bacA, which confer resistance to various antibiotics such as methicillin, beta-lactam, tetracycline, fluoroquinolone, macrolide, aminoglycoside, nucleoside, fosfomycin, and bacitracin.
Transcription tuned by S-nitrosylation underlies a mechanism for Staphylococcus aureus to circumvent vancomycin killing.
The study identifies MgrA and WalR as transcriptional regulators that undergo S-nitrosylation, which is crucial for vancomycin resistance in Staphylococcus aureus. Disruption of S-nitrosylation at specific cysteine residues reduces resistance.
Antibiotic Susceptibility Profiling of Human Pathogenic Staphylococcus aureus Strains Using Whole Genome Sequencing and Genome-Scale Annotation Approaches.
The study identified several AMR genes in multidrug-resistant S. aureus strains, including blaZ, mecA, mecC, norA, norC, MgrA, tet(45), APH(3′)-IIIa, ermC, AAC(6′)-APH(2″), and fusC. These genes confer resistance to various antibiotics such as beta-lactams, fluoroquinolones, tetracyclines, aminoglycosides, macrolides, lincosamides, streptogramin B, and fusidic acid.
Population structure, resistome, and virulome of Staphylococcus chromogenes strains from milk of subclinical bovine mastitis in South Africa.
The study identified four core antimicrobial resistance genes (dfrC, mgrA, norA, and tet(38)) in bovine-derived Staphylococcus chromogenes isolates, which confer resistance to trimethoprim, fluoroquinolones, and tetracyclines. In contrast, porcine-derived isolates harbored a more diverse set of resistance determinants.
Network analysis of antimicrobial resistance in Staphylococcus aureus: characterization of hub genes and their functional implications.
The study identifies hub genes involved in antimicrobial resistance in Staphylococcus aureus, including mecA, fosB, arlR, mepA, mgrA, arlS, and msrA2, which are associated with mechanisms such as efflux pump regulation, target protection, and target replacement.
