A Consideration of Antibiotic Resistance

Scientists have confirmed for the first time that bacteria can change form to avoid being detected by antibiotics in the human body. Studying samples from  elderly patients  with recurring urinary tract infections, the Newcastle University team used state-of-the art techniques to identify that a bacteria can lose its  cell wall —the common target of many groups of antibiotics. The research by the Errington lab which turns on its head current thinking about the bacteria's ability to survive without a cell wall, known as "L-form switching", is published today in  Nature Communications .

Antimicrobial Properties of Plant Essential Oils against Human Pathogens and Their Mode of Action

Abstract A wide range of medicinal and aromatic plants (MAPs) have been explored for their essential oils in the past few decades. Essential oils are complex volatile compounds, synthesized naturally in different plant parts during the process of secondary metabolism. Essential oils have great potential in the field of biomedicine as they effectively destroy several bacterial, fungal, and viral pathogens. The presence of different types of aldehydes, phenolics, terpenes, and other antimicrobial compounds means that the essential oils are effective against a diverse range of pathogens. The reactivity of essential oil depends upon the nature, composition, and orientation of its functional groups. The aim of this article is to review the antimicrobial potential of essential oils secreted from MAPs and their possible mechanisms of action against human pathogens. This comprehensive review will benefit researchers who wish to explore the potential of essential oils in the development of ...
