There are two main types of bacteria, and these categories reflect the microbes' biology and their vulnerability to different antibiotics.

Gram-negative bacteria pose a significant threat to global health due to their high resistance to antibiotics compared to ...

The results were published on June 25 in Scientific Reports. This finding is a new concept: both Gram-positive and -negative bacteria are involved in the progression of periodontal bone loss.

Being able to differentiate bacterial species is important for a host of reasons. While molecular techniques can determine the specific species, even without getting into the molecular nitty gritty, ...

This means that gram-negative bacteria can be harder to treat than gram-positive bacteria. This type of bacteria gets its name from the gram stain test.

Gram-positive and gram-negative bacteria differ in the composition of their cell walls. Gram-negative bacteria have a double layer of protection, making them more difficult to kill, Muñoz said.

The research team, including, from left, Nandan Haloi, Archit Kumar Vasan, Emily Geddes and Emad Tajkhorshid, invented and tested a new method for determining how chemical compounds interact with ...

Cannabidiol analogs active against wide range of Gram-positive bacteria and a subset of Gram-negative bacteria, including those responsible for gonorrhea, meningitis, and Legionnaires’ disease.
