Four multidrug-resistant strains of extraintestinal pathogenic Escherichia coli (ExPEC) were identified in puppies with acute pneumonia, carrying resistance genes such as TEM, CTX-M-55, mec, tet, AAC-IId, cmlA, dfrA, and sul. These strains were classified as ST131 or ST43 and showed resistance to cephalosporins, tetracyclines, and penicillins, but were susceptible to aminoglycosides, beta-lactamase inhibitors, carbapenems, chloramphenicols, and sulfonamides.

The study identified blaEC-8 and blaZEG-1 genes conferring resistance to beta-lactams, and dfrA gene conferring resistance to trimethoprim in Shigella sonnei isolates.

The study identified multiple AMR genes in multidrug-resistant E. coli isolates from Taihe Black-Boned Silky Fowl farms, including blaTEM, blaOXA-10, tetA, tetR, floR, cmlA, qnrS, strA, strB, aadA, aac(3)-IId, sul, and dfrA. These genes were associated with resistance to beta-lactams, tetracyclines, chloramphenicol, fluoroquinolones, aminoglycosides, and sulfonamides.

The study identified high levels of multidrug resistance in Staphylococcus aureus isolates from diabetic foot infections in Beira, Mozambique, with resistance genes blaZ, mecA, vancA, vancB, ermB, ermC, dfrA, and dfrG being prevalent.

The study identifies multiple AMR genes and mutations associated with colistin and carbapenem resistance in Klebsiella pneumoniae and Enterobacter isolates, including beta-lactamases, fosfomycin resistance genes, and efflux pumps. Mutations in ompK35 were found to contribute to carbapenem resistance.

The study established tentative CLSI M45 antimicrobial susceptibility testing breakpoints for Pseudomonas other than Pseudomonas aeruginosa (POPA). It identified various beta-lactamase genes, including metallo-beta-lactamases (MBLs) such as bla POM-1, bla POM-2, bla PAM-1, bla PST-1, bla VIM-2, bla CARB-2, bla DHA-1, and bla IMP-13, which confer resistance to carbapenems. Additionally, multidrug-resistant efflux pumps like ttgABC and tmexCD-toprJ were found to contribute to carbapenem resistance. Other resistance genes for aminoglycosides, trimethoprim-sulfamethoxazole, quaternary ammonium compounds, chloramphenicol, and fluoroquinolones were also detected.

The study characterizes the plasmid diversity in Klebsiella pneumoniae ST307 isolates co-producing KPC and NDM carbapenemases, identifying multiple resistance genes and plasmid types involved in carbapenem resistance.

The study identified several antibiotic resistance genes in Staphylococcus isolates from dogs in Vietnam, including aacA-aphD, tetK, gyrA, mecA, msrA, dfrA, and ermA, highlighting the prevalence of multidrug-resistant Staphylococcus species.

The study identified several antimicrobial resistance (AMR) genes in a dairy wastewater sample, including beta-lactamases, aminoglycoside acetyltransferases, tetracycline resistance proteins, quinolone resistance proteins, and macrolide ribosome methyltransferases. These genes were found in various bacterial species such as Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa.

The study identified bla CTX-M, bla TEM, dfrA, stx1, and stx2 genes in E. coli isolates from meat products in Sohag Governorate, Egypt, highlighting the presence of multidrug-resistant and extended-spectrum beta-lactamase-producing strains.

The study identifies various AMR genes and mutations in Klebsiella pneumoniae, highlighting knowledge gaps in existing annotation tools and databases for accurate resistance prediction.

PanARGMiner effectively identifies key resistance genes from pan-genomic datasets, including both known and novel AMR genes, across multiple bacterial species.

The study characterizes the complete nucleotide sequence of the conjugative multiresistance plasmid pSK41 from Staphylococcus aureus, identifying resistance genes such as aacA-aphD, aadD, smr, and dfrA, which confer resistance to aminoglycosides, neomycin, antiseptics/disinfectants, and trimethoprim, respectively.
