Zeocin is a trade name for a formulation of phleomycin D1, a glycopeptide antibiotic and one of the phleomycins from Streptomyces verticillus belonging to the bleomycin family of antibiotics. [1] It is a broad-spectrum antibiotic that is effective against most aerobic organisms including bacteria, filamentous fungi, yeast, plant, and animal cells.

Sometimes, whether an antibiotic is marked as resistant is also based on bacterial characteristics that are associated with known methods of resistance such as the potential for beta-lactamase production. [28] [20] Specific patterns of drug resistance or multidrug resistance may be noted, such as the presence of an extended-spectrum beta ...
An illustrative diagram explaining drug resistance. Drug resistance is the reduction in effectiveness of a medication such as an antimicrobial or an antineoplastic in treating a disease or condition. [1] The term is used in the context of resistance that pathogens or cancers have "acquired", that is, resistance has evolved.
Two other mechanisms conferring unstable heteroresistance, resulting in an increased gene dosage of the resistance genes, are plasmid copy number increase and transposition of the resistance genes onto cryptic plasmids which increases in copy number. However, this mechanism is considered unstable, leading to a rapid return to susceptibility ...

This resistance mechanism underscores the importance of the structural integrity of the β-lactam ring for the antibiotic's function. [24] The color change from colorless or light yellow to amber or even red in an aqueous solution of a β-lactam antibiotic can denote β-lactamase hydrolysis of amide bonds in the β-lactam ring.
