The study describes the development of genetic tools for Capnocytophaga canimorsus, including the identification of functional resistance genes ermF, cfxA, and tetQ, which can be used as selection markers for plasmid maintenance in C. canimorsus and other Capnocytophaga species.

The study identified bla TEM-1, cfx A, tet M, tet W, and tet Q as the most prevalent antibiotic resistance genes in endodontic infections. bla TEM-1 was more prevalent in primary infections, while tet M remained unchanged after treatment. Vancomycin resistance genes were not detected.

The study identified several resistance genes, including cepA, cfiA, cfxA, tetQ, ermF, and mefA, in anaerobic bacteria isolated from intra-abdominal infections in Japan. A mutation in the gyrA gene was also found to confer resistance to fluoroquinolones.

The study identifies various antibiotic resistance genes (ARGs) associated with multidrug resistance, including macrolide, beta-lactam, tetracycline, and methicillin resistance genes, highlighting the presence of these genes in postmortem microbiome samples.

The study identified several tetracycline, macrolide, aminoglycoside, beta-lactam, sulfonamide, mercury, and biocide resistance genes in beef feedlots, catch basin water, soil, and urban sewage influent. Tetracycline resistance was predominant in beef production systems, while urban sewage influent showed a diverse resistome with resistance to multiple antimicrobial classes.

The study identifies the cfiA gene as the primary mechanism of carbapenem resistance in Bacteroides fragilis, along with other resistance genes such as cfxA, cepA, ermF, and nim. These genes contribute to resistance against various antibiotics including carbapenems, cefoxitin, clindamycin, and metronidazole.

The study identified several beta-lactamase and vancomycin resistance genes that were significantly increased in placebo-treated patients compared to ribaxamase-treated patients following ceftriaxone exposure.

The study identified high resistance rates in Bacteroides fragilis isolates, particularly to penicillin G, tetracycline, clindamycin, and cefoxitin. Key resistance genes included tetQ, ermF, cepA, cfxA, and cfiA.

The study identifies cfiA and cepA as key carbapenem resistance genes in Bacteroides fragilis sensu stricto, and bla and cfx as important beta-lactam resistance genes in non-fragilis Bacteroides species. It also highlights the role of insertion sequences in activating cfiA-mediated carbapenem resistance.

The study identified ermF, tetQ, and cfxA as key AMR genes in Prevotella species, showing strong correlations with resistance to azithromycin, clindamycin, doxycycline, and ceftazidime. All isolates were resistant to tobramycin.

The study identified increased resistance gene burden in healthy volunteers after antibiotic treatment, particularly with cfxA, tetO, and tet40 genes associated with β-lactam and tetracycline resistance.

The study found that prolonged amoxicillin treatment leads to an increase in the abundance and diversity of antimicrobial resistance genes (ARGs) in the gut microbiome, particularly beta-lactamase genes such as cfxA and its variants, as well as tetracycline and macrolide resistance genes.

The study identifies that root canal microbiota in T2DM patients harbor a higher prevalence of antimicrobial resistance genes (ARGs) compared to non-diabetic patients, particularly for tetW, tetM, ermB, ermC, cfxA, and tetQ.

The study identified various antimicrobial resistance genes (ARGs) in the oral microbiota, including mefA, msrD, ermB, ermF, cfxA, blaCSP(1), tetM, tetQ, and pgpB, which confer resistance to antibiotics such as erythromycin, azithromycin, penicillin, ampicillin, tetracycline, and colistin. These genes were found in multiple bacterial species and were associated with different resistotypes in healthy, caries, and periodontitis groups.

The study identifies several AMR genes in anaerobic Gram-negative bacteria, including nimE for metronidazole resistance, ermF for clindamycin resistance, cfiA for imipenem resistance, cepA for piperacillin-tazobactam resistance, and cfxA for cefoxitin resistance.

The study identified several extended-spectrum beta-lactamase (ESBL) genes during enteric infection, with some persisting post-recovery, indicating potential gene transfer within the community. The research highlights the persistence of antimicrobial resistance genes in specific microbial hosts, emphasizing the need for further investigation into the dynamics of resistance gene transmission.

The study identified and compared the prevalence of antibiotic resistance genes in intestinal Bacteroides, Parabacteroides and Phocaeicola isolates from healthy and carbapenem-treated patients in European countries, highlighting differences in gene carriage between gut microbiota and clinical strains.

The study identifies three antibiotic resistance genes, cfxA, cepA, and copA, in a multidrug-resistant Bacteroides fragilis strain isolated from a giant panda with vaginitis.

The study found that extending surgical antimicrobial prophylaxis beyond 24 hours did not increase postoperative complications but led to a higher abundance of beta-lactam resistance genes, including TEM, BlaZ, SHV, CfxA, and PBP2, as well as aminoglycoside-modifying enzymes like AAC(6'), ANT(3"), ANT(6), APH(2"), APH(3'), APH(3"), and APH(6) in the fecal resistome of horses.
