Gram staining, first developed in 1884 by Hans Christian Gram, remains a foundation of microbiology for separating bacteria into Gram-positive and Gram-negative groups. This simple yet powerful test ...
Gram-negative bacteria deploy a range of protein toxins as mediators of inter-bacterial competition and pathogenicity. Among these, colicins comprise a class of ribosomally synthesised bacteriocins ...
The Tol-Pal complex maintains bacterial outer membrane (OM) stability by regulating lipid homeostasis. (Left) In Gram-negative bacteria, the OM acts as a protective barrier, blocking entry of harmful ...
Expert Rev Anti Infect Ther. 2010;8(8):879-885. We recommend a thorough evaluation of patients with non-HACEK Gram-negative endocarditis to assess the necessity of surgical intervention. Decision to ...
Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories reflect big differences in the microbes' biology, and they also dictate how ...
