Gram staining is a type of differential staining used to distinguish between Gram positive and Gram negative bacterial groups, based on inherent differences in their cell wall constituents. Stains ...

There are many ways of classifying bacteria. One method is based on the cell membrane. In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, ...

LpxC inhibitors target a zinc-dependent deacetylase that catalyses the first committed step in lipid A biosynthesis, an essential process for the viability of Gram-negative bacteria. As lipid A forms ...

There are two main types of bacteria, and these categories reflect the microbes' biology and their vulnerability to different antibiotics. When you purchase through links on our site, we may earn an ...

The World Health Organisation (WHO), on Monday, published its first-ever list of antibiotic-resistant “priority pathogens”, a catalogue of 12 families of bacteria that posed threat to human health.

Mouths are filthy, harboring the second largest microbiome of the human body. Some bacteria can help break down food, among other responsibilities; other bacteria can travel into the mouth on food, ...

Gram-positive bacteria have thick cell walls. A Gram stain test, which involves a chemical dye, stains the bacterium’s cell wall purple. On the other hand, gram-negative bacteria stain pink instead.

Gram staining is one way scientists can identify bacteria. Gram-positive bacteria, such as Staphylococcus, appear blue or purple under a microscope when scientists apply a stain. Conversely, ...

Gram-positive bacteria show blue or purple after Gram-staining in a laboratory test. They have thick cell walls. Gram-negative bacteria show pink or red on staining and have thin walls. They release ...
