The study identified several AMR genes, including blaOXA61, blaOXA184, tet(O), tet(O/32/O), aadE-Cc, and aph(3')-III, which confer resistance to beta-lactams, tetracyclines, and aminoglycosides in Campylobacter isolates. Additionally, mutations in the cmeR gene were linked to increased resistance to erythromycin, fluoroquinolones, and macrolides.

The study identified seven resistance genes and several mutations associated with antimicrobial resistance in Campylobacter jejuni isolates, demonstrating the effectiveness of whole-genome sequencing in predicting resistance.

The study identified various AMR genes including aminoglycoside-modifying enzymes, tetracycline resistance genes, and beta-lactamases in Campylobacter jejuni and C. coli isolates from ruminants. Mutations in gyrA and rpsL were linked to quinolone and streptomycin resistance, respectively. The presence of specific genetic determinants correlated with phenotypic resistance.

The study identified several AMR genes in Streptococcus suis isolates from diseased pigs in Italy, including ermb, tet(O), aac6-aph2, ant6-ia, aph3-iiia, spw, tet(40), tet(W), tet(O/W/32/O), tet(W/N/N), erm(47), lnuB, lsaE, and optrA, which confer resistance to various antibiotics such as erythromycin, tetracycline, gentamicin, lincomycin, and linezolid.

The study identified several AMR genes in Enterococcus hirae isolates from beef cattle feedlots, including tetracycline resistance genes (tet(L), tet(M), tet(O), tet(S/M), tet(O/32/O)), macrolide resistance gene erm(B), and aminoglycoside resistance genes (aac(6')-Iid, ant(6)-Ia, aph(3')-III, sat4).

The study identified 18 AMR genes in Limosilactobacillus species, primarily in L. reuteri from animal sources, including tetracycline, aminoglycoside, macrolide-lincosamide-streptogramin, and lincomycin resistance genes.

The study found that the withdrawal of antibiotic growth promoters in China led to an increase in antibiotic resistance in Campylobacter coli, particularly for gentamicin and florfenicol. Several resistance genes, including aadE-Cc, aac(6')-aph(2"), ant(6)-la, aph(3")-lll, aph(2")-lf, tet(O), tet(M), tet(O/32/O), cat, fexA, cfr(C), optrA, blaOXA-193, blaOXA-489, and blaOXA-61, were identified. Mutations in 23S rRNA and gyrA were also associated with resistance to erythromycin and ciprofloxacin, respectively.

The study identifies a novel low-level tetracycline resistance gene, tet(O)_3, in two Campylobacter jejuni isolates from chicken meat. This gene is highly responsive to low tetracycline concentrations and shows similarity to a tet(O) gene in Streptococcus pneumoniae.

The study identified 22 different resistance genes and gene variants, including erm(B), aph(3')-IIIa, aadE, catA, lnu(C), blaOXA, sat4, tet(O), and point mutations in gyrA, 23S rRNA, and rpsL, associated with antimicrobial resistance in thermotolerant Campylobacter spp.

The study identified antimicrobial resistance genes such as erm(X), tet(O), tet(O/23/O), tet(Q), and tet(W) in Bifidobacterium isolates from Cambodian infants, highlighting the presence of resistance mechanisms in the gut microbiota.

The study identified several AMR genes in Campylobacter strains from NAE and conventional broiler complexes, including bla OXA-61, bla OXA-184, tet (O), tet (O/32/O), and aph (3′)-III. These genes conferred resistance to various antibiotics such as tetracycline, cefoxitin, aztreonam, and gentamicin.

The study identifies tetracycline and clindamycin resistance genes (tet and erm) in various Clostridia species from preterm infants, highlighting their role as reservoirs of antimicrobial resistance.

The study identified 29 ARG subtypes across eight types in 13 known, five unknown, and 18 unclassified species, highlighting the complex and dynamic nature of antimicrobial resistance in the gut microbiome. Notably, the cfr(C) gene was detected in 11 bacterial species following antimicrobial treatment, with mutation patterns characterized in several species.
