efflux pump regulator
Overview
RamAp Is an Efflux Pump Regulator Carried by an IncHI2 Plasmid.
The study identifies ramAp, a plasmid-borne efflux pump regulator, which enhances resistance to multiple antibiotics including chloramphenicol, azithromycin, nalidixic acid, ciprofloxacin, sulfamethoxazole, trimethoprim, tetracycline, and tigecycline.
Antimicrobial Resistance and Mechanisms of Azithromycin Resistance in Nontyphoidal Salmonella Isolates in Taiwan, 2017 to 2018.
The study identifies mph(A), erm(42), erm(B), and ramAp as the primary mechanisms of azithromycin resistance in non-typhoidal Salmonella isolates from Taiwan.
Carbapenem resistance in extensively drug-resistant Salmonella enterica serovar Agona and AmpC β-lactamase-producing S. Infantis.
The study identifies the loss of porins OmpC_378 and OmpD as critical for carbapenem resistance in Salmonella strains producing AmpC or ESBL β-lactamases. It also characterizes several beta-lactamase genes, including bla CTX-M-55, bla TEM-1B, and bla CMY-2, as well as the efflux pump regulatory gene ramAp.
