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 ...

A new crop of drug-resistant superbugs is in our midst, and experts believe that they could rival the deadly superbug MRSA. A ...

When exposed to antibiotics, approximately one out of every 10 8 -10 9 bacteria develops resistance due to spontaneous ...

1-5 What Bacteria Use Quorum Sensing? Both gram-negative and gram-positive bacteria use quorum sensing. Generally, gram-negative bacteria employ acylated homoserine lactones as autoinducers, which ...

This medium is both selective and differential. The selective ingredients are the bile salts and the dye, crystal violet which inhibit the growth of Gram-positive bacteria. The differential ingredient ...

A new study by researchers at George Washington University has found that certain bacteria living in the nose may influence ...

Saccharin destabilizes bacterial membranes and interferes with DNA replication, causing lysis and impairing virulence traits. The sweetener also re-sensitizes multidrug-resistant pathogens to ...

That process led to the group discovering a lasso peptide that exhibited broad-spectrum antibiotic activity and was effective at killing both gram-positive and gram-negative pathogenic bacteria, along ...

In gram-negative bacteria, the most common mechanism of resistance is the hydrolysis, or breaking apart, of the antibiotics by enzymes referred to as the beta-lactamases. There are two broad classes ...

Antimicrobial resistance is a global issue, making the search for a new generation of antibiotics imperative. Scientists ...
