Antimicrobial Resistance in Bacteria: Mechanisms and Current Challenges
This paper characterizes several beta-lactamases, including TEM-1, SHV-1, CTX-M-15, and NDM-1, which confer resistance to various beta-lactam antibiotics. It also identifies erm(B) and mef(A) as mechanisms of macrolide, lincosamide, and streptogramin B resistance. Additionally, aadA1 and aac(6')-Ib are noted for aminoglycoside resistance, while catA1 and floR contribute to chloramphenicol resistance. The vanA gene is associated with glycopeptide resistance, and mcr-1 is linked to polymyxin resistance.
Genome-based characterization of two Colombian clinical Providencia rettgeri isolates co-harboring NDM-1, VIM-2, and other β-lactamases.
Two Colombian clinical Providencia rettgeri isolates co-harboring NDM-1, VIM-2, and other β-lactamases were characterized. The isolates exhibited resistance to multiple antibiotics, including carbapenems, cephalosporins, and aminoglycosides.
Population genomics of the food-borne pathogen Vibrio fluvialis reveals lineage associated pathogenicity-related genetic elements.
The study identified 21 antimicrobial resistance genes in Vibrio fluvialis, with 19 of them predominantly present in VflPop2. The tetracycline resistance gene tet(35) was found in 95% of VflPop2 strains, highlighting its significance in the population. Additionally, the plasmid pBD146 was associated with resistance to trimethoprim-sulfamethoxazole, and the presence of dfr6 gene in pBD146 was linked to this resistance.
Incidence, genetic diversity, and antimicrobial resistance profiles of Vibrio parahaemolyticus in seafood in Bangkok and eastern Thailand.
The study identified several antimicrobial resistance genes in Vibrio parahaemolyticus isolates from seafood in Bangkok and eastern Thailand, including blaCARB, tet(34), tet(35), qnrC, dfrA6, and blaCTX-M-55, which confer resistance to various antibiotics such as ampicillin, amoxicillin, piperacillin, tetracycline, doxycycline, ciprofloxacin, and trimethoprim.
Genomic mining of Vibrio parahaemolyticus highlights prevalence of antimicrobial resistance genes and new genetic markers associated with AHPND and tdh + /trh + genotypes.
The study identified several antimicrobial resistance genes in Vibrio parahaemolyticus strains, including bla CARB-21, bla CARB-23, tet(B), and dfrA6, which confer resistance to beta-lactams, tetracycline, and trimethoprim-sulfamethoxazole.
