The usual active lifestyle can change and the bacteria can remain in intracellular vacuoles entering into a slow non-growing state of persistence thus promoting their survival from antibiotics. [12] Fungal persister cells are a common cause of recurring infections due to Candida albicans a common biofilm infection of implants. [5]
TGA is effective in eradicating biofilms in otolaryngologic infections, [2] as biofilms are often resistant to treatment with antibiotics. [3] Biofilms are complex communities of bacteria that can adhere to surfaces and are known to be highly resistant to antibiotic treatment and immune responses, [4] [5] so the ability of TGA to effectively ...
Antibiotics are largely ineffective in clearing biofilms. The most common treatment for these infections is to remove or replace the infected implant, though in all cases, prevention is ideal. The drug of choice is often vancomycin, to which rifampin or an aminoglycoside can be added.
An alternative to postsurgical antibiotic treatment is using antibiotic-loaded, dissolvable calcium sulfate beads, which are implanted with the medical device. These beads can release high doses of antibiotics at the desired site to prevent the initial infection. [48] Novel treatments for S. aureus biofilm involving nano silver particles ...
The level of antibiotic resistance in a biofilm is much greater than that of non-biofilm bacteria, and can be as much as 5,000 times greater. [50] The extracellular matrix of biofilm is considered one of the leading factors that can reduce the penetration of antibiotics into a biofilm structure and contributes to antibiotic resistance.

Phage therapy is the use of bacteriophages to treat bacterial infections. Bacteriophage treatment offers a possible alternative to conventional antibiotic treatments for bacterial infection. [55] It is conceivable that, although bacteria can develop resistance to phages, the resistance might be easier to overcome than resistance to antibiotics.
Cecropin A can destroy planktonic and sessile biofilm-forming uropathogenic E. coli (UPEC) cells, either alone or when combined with the antibiotic nalidixic acid, synergistically clearing infection in vivo (in the insect host Galleria mellonella) without off-target cytotoxicity. The multi-target mechanism of action involves outer membrane ...
Biofilms help to hinder the action of antibiotics and can contribute to treatment failure. [30] [31] To successfully colonize its host, H. pylori uses many different virulence factors including oxidase, catalase, and urease. [32] Urease is the most abundant protein, its expression representing about 10% of the total protein weight. [33]
