Understanding the molecular Tetracycline resistance by antibiotic inactivation was first identified in commensal organisms but has since been reported in environmental and pathogenic microbes
Antibiotic resistance happens when bacteria change, so antibiotic medicines can't kill them or stop their growth
Antibiotic are mostly used in animals, including chickens, for the treatment or prevention of diseases [1,2,3]
Tetracycline resistance is widespread among Gram-positive and Gram-negative bacteria and can be the result of pumping the drug out of the cell before it reaches it site of action (efflux), protection of the ribosomal binding site, which decreases drug binding, or changes in the permeability of the cell envelope that Tetracyclines are among the most used antibiotics in livestock worldwide

Manure samples, on the other hand, showed that all three manure Antibiotic resistance is a major subset of AMR, that applies specifically to bacteria that become resistant to antibiotics
CDC's NHSN is the nation's most widely used healthcare-associated infection tracking system and includes information on antimicrobial resistance and antibiotic use
The unique 3D chemical shape of tetracycline arises from a bend in the structure at the A,B-ring juncture, and this seems to be a distinguishing feature from other Notably, numerous clinical isolates are co-resistant to MLS and tetracyclines, since both resistance determinants are borne by the same mobile genetic elements
Tetracyclines (tetracycline, doxycycline, minocycline, tigecycline) are a class of medication used to manage and treat various
Resistance to tetracycline emerged soon after its discovery six decades ago
Antibiotic resistance is when bacteria change to resist antibiotics that used to effectively treat them
Tetracycline resistance is widespread among Gram-positive and Gram-negative bacteria and can be the result of pumping the drug out of the cell before it
