First, gram-negative bacteria have a thin cell wall that is about 1.5 to 10 nanometers across, whereas gram-positive bacteria have a thick cell wall measuring about 20 to 80 nanometers.

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.

Both Gram-positive and Gram-negative bacteria can cause disease. However, they require different treatments. Therefore, medical professionals need to be able to identify the type of bacteria to ...

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.

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, ...

In a recent study, researchers demonstrated that a novel compound could treat flesh-eating Gram-positive bacterial infections in mice, potentially offering a new class of antibiotics. Researchers at ...
