aminoglycoside antibiotic Drug Class Aminoglycosides are a group of antibiotics that are mostly effective against Gram-negative bacteria. These molecules consist of aminated sugars attached to a dibasic cyclitol. Aminoglycosides work by binding to the bacterial 30S ribosomal subunit (some work by binding to the 50S subunit), inhibiting the translocation of the peptidyl-tRNA from the A-site to the P-site and also causing misreading of mRNA, leaving the bacterium unable to synthesize proteins vital to its growth. antibiotic inactivation Resistance Mechanism Enzymatic inactivation of antibiotic to confer drug resistance. streptomycin Antibiotic Streptomycin is an aminoglycoside antibiotic used to treat different types of bacterial infections. Streptomycin works by binding to the bacterial 30S ribosomal subunit, causing misreading of mRNA and leaving the bacterium unable to synthesize proteins vital to its growth. APH(3'') AMR Gene Family Phosphorylation of streptomycin on the hydroxyl group at position 3''

major facilitator superfamily (MFS) antibiotic efflux pump AMR Gene Family Directed pumping of antibiotic out of a cell to confer resistance. Major facilitator superfamily (MFS) transporters and ABC transporters comprise the two largest and most functionally diverse of the transporter superfamilies. However, MFS transporters are distinct from ABC transporters in both their primary sequence and structure and in the mechanism of energy coupling. As secondary transporters they are, like RND and SMR transporters, energized by the electrochemical proton gradient. chloramphenicol Antibiotic Chloramphenicol is a bacteriostatic antimicrobial originally derived from the bacterium Streptomyces venezuelae. It was the first antibiotic to be manufactured synthetically on a large scale. It functions by inhibiting peptidyl transferase activity of the bacterial ribosome, binding to A2451 and A2452 residues in the 23S rRNA of the 50S ribosomal subunit and preventing peptide bond formation. florfenicol Antibiotic Florfenicol is a fluorine derivative of chloramphenicol, where the nitro group (-NO2) is substituted by a sulfomethyl group (-SO2CH3) and the hydroxyl group (-OH), by a fluorine group (-F). The action mechanism is the same as chloramphenicol's, where the antibiotic binds to the 23S RNA of the 50S subunit of bacterial ribosomes to inhibit protein synthesis. phenicol antibiotic Drug Class Phenicols are broad spectrum bacteriostatic antibiotics acting on bacterial protein synthesis. More specifically, the phenicols block peptide elongation by binding to the peptidyltansferase centre of the 70S ribosome. efflux pump complex or subunit conferring antibiotic resistance Efflux Component Efflux proteins that pump antibiotic out of a cell to confer resistance. antibiotic efflux Resistance Mechanism Antibiotic resistance via the transport of antibiotics out of the cell.

macrolide antibiotic Drug Class Macrolides are a group of drugs (typically antibiotics) that have a large macrocyclic lactone ring of 12-16 carbons to which one or more deoxy sugars, usually cladinose and desosamine, may be attached. Macrolides bind to the 50S-subunit of bacterial ribosomes, inhibiting the synthesis of vital proteins. Erm 23S ribosomal RNA methyltransferase AMR Gene Family Erm proteins are part of the RNA methyltransferase family and methylate A2058 (E. coli nomenclature) of the 23S ribosomal RNA conferring degrees of resistance to Macrolides, Lincosamides and Streptogramin b. This is called the MLSb phenotype. lincosamide antibiotic Drug Class Lincosamides (e.g. lincomycin, clindamycin) are a class of drugs which bind to the 23s portion of the 50S subunit of bacterial ribosomes. This interaction inhibits early elongation of peptide chains by inhibiting the transpeptidase reaction, acting similarly to macrolides. streptogramin antibiotic Drug Class Streptogramin antibiotics are natural products produced by various members of the Streptomyces genus. These antibiotics bind to the P site of the 50S subunit of bacterial ribosomes to inhibit protein synthesis. The family consists of two subgroups, type A and type B, which are simultaneously produced by the same bacterial species in a ratio of roughly 70:30. antibiotic target alteration Resistance Mechanism Mutational alteration or enzymatic modification of antibiotic target which results in antibiotic resistance.

antibiotic target replacement Resistance Mechanism Replacement or substitution of antibiotic action target, which process will result in antibiotic resistance. trimethoprim resistant dihydrofolate reductase dfr AMR Gene Family Alternative dihydropteroate synthase dfr present on plasmids produces alternate proteins that are less sensitive to trimethoprim from inhibiting its role in folate synthesis, thus conferring trimethoprim resistance. trimethoprim Antibiotic Trimethoprim is a synthetic 5-(3,4,5- trimethoxybenzyl) pyrimidine inhibitor of dihydrofolate reductase, inhibiting synthesis of tetrahydrofolic acid. Tetrahydrofolic acid is an essential precursor in the de novo synthesis of the DNA nucleotide thymidine. Trimethoprim is a bacteriostatic antibiotic mainly used in the prophylaxis and treatment of urinary tract infections in combination with sulfamethoxazole, a sulfonamide antibiotic. diaminopyrimidine antibiotic Drug Class Diaminopyrimidines are a class of organic compounds containing a pyrimidine ring substituted by two amine groups. They are inhibitors of dihydrofolate reductase, an enzyme critical for DNA synthesis.

Spectinomycin works by binding to the bacterial 30S ribosomal subunit inhibiting translation.

sulfonamide resistant sul AMR Gene Family The sul genes encode forms of dihydropteroate synthase that confer resistance to sulfonamide. sulfadiazine Antibiotic Sulfadiazine is a potent inhibitor of dihydropteroate synthase, interfering with the tetrahydrofolic biosynthesis pathway. Tetrahydrofolic acid is essential for folate synthesis, a precursor to many nucleotides and amino acids. sulfadimidine Antibiotic Sulfadimidine is an alkaline sulfonamide antibiotic that inhibits dihydropteroate synthase, and enzyme in the tetrahydrofolic acid biosynthesis pathway. This interferes with the production of folate, which is a precursor to many amino acids and nucleotides. sulfadoxine Antibiotic Sulfadoxine is an inhibitor of dihydropteroate synthase, interfering with the tetrahydrofolic biosynthesis pathway. Tetrahydrofolic acid is essential for folate synthesis, a precursor to many nucleotides and amino acids. sulfamethoxazole Antibiotic Sulfamethoxazole is a sulfonamide antibiotic usually taken with trimethoprim, a diaminopyrimidine antibiotic. Sulfamethoxazole inhibits dihydropteroate synthase, essential to tetrahydrofolic acid biosynthesis. This pathway generates compounds used in the synthesis of many amino acids and nucleotides. sulfisoxazole Antibiotic Sulfisoxazole is an inhibitor of dihydropteroate synthase, interfering with the tetrahydrofolic biosynthesis pathway. Tetrahydrofolic acid is essential for folate synthesis, a precursor to many nucleotides and amino acids. sulfacetamide Antibiotic Sulfacetamide is a very soluable sulfonamide antibiotic previously used to treat urinary tract infections. Its relatively low activity and toxicity to those with Stevens-Johnson syndrome have reduced its use and availability. mafenide Antibiotic Mafenide is a sulfonamide used topically for treating burns. sulfasalazine Antibiotic Sulfasalazine is a derivative of the early sulfonamide sulfapyridine (salicylazosulfapyridine). It was developed to increase water solubility and is taken orally for ulcerative colitis. sulfamethizole Antibiotic Sulfamethizole is a short-acting sulfonamide that inhibits dihydropteroate synthetase. sulfonamide antibiotic Drug Class Sulfonamides are broad spectrum, synthetic antibiotics that contain the sulfonamide group. Sulfonamides inhibit dihydropteroate synthase, which catalyzes the conversion of p-aminobenzoic acid to dihydropteroic acid as part of the tetrahydrofolic acid biosynthetic pathway. Tetrahydrofolic acid is essential for folate synthesis, a precursor of many nucleotides and amino acids. Many sulfamides are taken with trimethoprim, an inhibitor of dihydrofolate reductase, also disturbing the trihydrofolic acid synthesis pathway. antibiotic target replacement Resistance Mechanism Replacement or substitution of antibiotic action target, which process will result in antibiotic resistance.
