Using Nanoparticles to Treat Antibiotic Resistant Bacteria

Recent advances in the treatment of pathogenic infections using antibiotics and nano-drug delivery vehicles SUMMARY: This article talks about the different ways to combat antibiotic resistant bacterial infections. Most of the articles and methods focus on nanoparticles, coating nanoparticles with antibodies to detect pathogens, and creating an immune response using vaccination-like methods. LESSON COMMENTS: An… Continue reading Using Nanoparticles to Treat Antibiotic Resistant Bacteria

Structure and Function of MCR-4

Action and mechanism of the colistin resistance enzyme MCR-4 SUMMARY: Colistin is an antibiotic that is considered to be a last resort against antibiotic resistant bacteria. Unfortunately, an enzyme called MCR-4 has evolved which makes bacteria resistant to colistin. Researchers want to understand the structure and function of MCR-4 in order to combat it. There… Continue reading Structure and Function of MCR-4

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

Effects of Antibiotics on Plankton

Interspecies Interactions Reverse the Hazard of Antibiotics Exposure: A Plankton Community Study on Responses to Ciprofloxacin hydrochloride SUMMARY: Antibiotics that have made their way into aquatic ecosystems may have an effect on the food chains there. This study tested the effects of ciprofloxacin hydrochloride on 2 different types of algae (phytoplankton) and a species of… Continue reading Effects of Antibiotics on Plankton
