The overuse of fluoroquinolone and other antibiotics fuels antibiotic resistance in bacteria, which can inhibit the treatment of antibiotic-resistant infections. [27] [28] [29] Their excessive use in children with otitis media has given rise to a breed of bacteria resistant to antibiotics entirely. [30]
Doxycycline is a broad-spectrum antibiotic of the tetracycline class used in the treatment of infections caused by bacteria and certain parasites. [1] It is used to treat bacterial pneumonia , acne , chlamydia infections , Lyme disease , cholera , typhus , and syphilis . [ 1 ]
Other research has been devoted to finding antibiotic resistance breakers (ARB's) which enhance an antibiotic's potency. This effect is mediated through direct antibacterial activity of the ARB, targeting and destroying mechanisms of bacterial resistance thereby allowing the antibiotic to function properly, interacting with the host to trigger ...
Knowing what genes cause antibiotic resistance -- and where they are in the body -- is critical for preventing further antibiotic resistance. Antibiotic resistance: new discovery could change the ...
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
Tetracyclines are generally used in the treatment of infections of the urinary tract, respiratory tract, and the intestines and are also used in the treatment of chlamydia, especially in patients allergic to β-lactams and macrolides; however, their use for these indications is less popular than it once was due to widespread development of resistance in the causative organisms.
Backup treatments can have serious side-effects; for example, antibiotics like aminoglycosides (such as amikacin, gentamicin, kanamycin, streptomycin, etc.) used for the treatment of drug-resistant tuberculosis and cystic fibrosis can cause respiratory disorders, deafness and kidney failure.
[104] Inappropriate antibiotic treatment and overuse of antibiotics have contributed to the emergence of antibiotic-resistant bacteria. However, potential harm from antibiotics extends beyond selection of antimicrobial resistance and their overuse is associated with adverse effects for patients themselves, seen most clearly in critically ill ...
