Using NAC Against Antibiotic Resistance Bacteria

N-acetyl Cysteine Coated Gallium Particles Demonstrate High Potency against Pseudomonas aeruginosa PAO1 SUMMARY: Antibiotic resistant bacterial infections are on the rise, especially in hospitals. One of the culprits is the bacteria Pseudomonas aeruginosa (POA1). Researchers are quickly running out of antibiotics to use against resistant strains. The problem has reached the point where colistin, a… Continue reading Using NAC Against Antibiotic Resistance Bacteria

Phage Therapy on Infected Graft

Phage treatment of an aortic graft infected with Pseudomonas aeruginosa SUMMARY: The first part of this article talks about using phage and antibiotics (separately and together) in vitro to reduce bacteria biofilm. Researchers found that phage alone was enough to reduce biofilm to almost zero; however, there is the concern (noted in other papers) that… Continue reading Phage Therapy on Infected Graft

Cholera Biodiversity in Humans

Vibrio Cholerae genomic diversity within and between patients SUMMARY: Researchers looked at 122 samples of cholera in 8 different cholera patients; five were from Bangladesh and three were from Haiti. They found that the cholera bacteria genomes were different in water versus the human gut; one particularly interesting mutation was that the bacteria stopped forming… Continue reading Cholera Biodiversity in Humans
