Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative ... in the chemical composition of bacterial cell walls that makes a difference in the ...

Gram positive bacteria are those that stain purple. They are usually non-pathogenic and their cell walls contain a thick layer of peptidoglycan.

Gram-positive bacteria are bacteria with thick cell walls. In a Gram stain test, these organisms yield a positive result. Here’s why knowing whether the result is positive or negative is important.

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria ...

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.
