Overview
Genome Characterization of mcr-1-Positive Escherichia coli Isolated From Pigs With Postweaning Diarrhea in China.
The study identifies multiple antimicrobial resistance genes, including mcr-1.1 and mcr-3.1, in multidrug-resistant E. coli isolates from pigs with postweaning diarrhea in China.
Molecular characterization of carbapenemase and extended spectrum beta-lactamase producing Acinetobacter baumannii isolates causing surgical site infections in Ethiopia.
The study identified several beta-lactamase genes, including bla CTX-M−15, bla CTX-M−65, bla TEM−1B, bla OXA−1, bla OXA−69, bla OXA−23, bla OXA−66, and bla NDM−1, which confer resistance to various beta-lactam antibiotics in Acinetobacter baumannii isolates causing surgical site infections in Ethiopia.
Comparative genomics analysis of Salmonella Enteritidis isolated from clinical cases associated with chicken.
Five Salmonella Enteritidis isolates were analyzed, revealing multiple antimicrobial resistance genes and chromosomal mutations. Key resistance genes included bla CTX−M−55, bla TEM−141, bla TEM−1B, aac(6')-Iaa, aph(3’)-IIa, aph(3’’)-Ib, aph(6)-Id, tet(A), floR, fosA3, and sul2. Chromosomal mutations in gyrA (D87G/D87Y) and acrB (F28L/L40P) were also identified, contributing to fluoroquinolone and multidrug resistance.
Drug resistant Klebsiella pneumoniae from patients and hospital effluent: a correlation?
The study identified multiple antibiotic resistance genes in clinical Klebsiella pneumoniae isolates, including bla TEM, bla SHV, bla CTX-M, and bla OXA families, as well as aminoglycoside, fluoroquinolone, and sulfonamide resistance genes. Effluent isolates showed fewer resistance genes and lower resistance levels compared to clinical isolates.
Molecular epidemiology of extended-spectrum beta-lactamase producing Gram-negative bacteria among surgical site infection patients in Ethiopia: a multicenter prospective study.
The study identified bla CTX-M−15, bla TEM−1B, and bla SHV−187 as the most prevalent ESBL genes among Gram-negative bacteria isolated from surgical site infections in Ethiopia.
Genetic insights into antimicrobial resistance and virulence characteristics of Salmonella enterica isolated from Nile tilapia sourced from retail markets in Thailand.
The study identified multiple antimicrobial resistance (AMR) genes in Salmonella enterica isolates from Nile tilapia, including beta-lactamases (bla TEM−1B, bla CTX−M−55, bla CTX−M−14, bla LAP−2), quinolone resistance genes (qnrS1, qnrS13), tetracycline resistance genes (tet(A), tet(B), tet(M)), aminoglycoside resistance genes (aadA2, aph(3’’)-Ib, aph(6)-Id, aac(6’)-Ia), sulfonamide resistance genes (sul1, sul2, sul3), florfenicol resistance gene (floR), and efflux pump systems (mdsABC, mdtK).
Genomic analysis of multidrug-resistant Salmonellaenterica Serovar Montevideo isolates in China.
The study identified multiple AMR genes in Chinese S. Montevideo isolates, including beta-lactamases (bla TEM−1B, bla OXA−1, bla LAP−2, bla CTX−M−55, bla CTX−M−65, bla DHA−1), quinolone resistance genes (qnrS2, qnrS1, qnrA1, qnrB6, qnrB4, qepA1), macrolide resistance genes (mphA, mphE, msrE, mphB), tetracycline resistance genes (tetA, tetD, tetB), sulfonamide resistance genes (sul1, sul2, dfrA14, dfrA12, dfrA27, sul3), and chloramphenicol resistance genes (floR, catA2, catB3).
