What Are the Causes of Antibiotics Resistance?

Antibiotic resistance A type of antibiotic resistance (ie, resistance). Refers to organisms (especially pathogenic microorganisms) that were originally sensitive to an antibiotic. After mutation, they become highly resistant to them.

Antibiotic resistance A type of antibiotic resistance (ie, resistance). Refers to organisms (especially pathogenic microorganisms) that were originally sensitive to an antibiotic. After mutation, they become highly resistant to them.

The reasons are: (1) the formation of an enzyme that can passivate or decompose hanginsin (such as any endophthalinase); (2) change the i) of the cell membrane; t3) change the site of antibiotic action; (4) Change the nature of the enzyme, making it insensitive to antibiotics; (5) change metabolic pathways and so on. Resistance mutations can occur on nuclear chromosomal genes or on plasmids. In some Gram-negative enterobacteria, such as Shigella dysenteriae (Shi); ellu d): seuter: ue, drug-resistant plasmids (that is, R factors or R plasmids) are often present, and their "L" Many different antibiotic resistance genes, this plasmid will be transferred between different strains or strains, which is extremely harmful to the prevention and control of infectious diseases. In microbial genetic research and breeding work, resistance to ^[1] Ideal marker for strain screening and genetic recombination.
