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, ...

The emergence of multi-drug resistance bacteria and healthcare-associated infections are frequent issues in the treatment of suppurating wounds. A group of researchers has created a bactericidal ...

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, ...

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. This ...

Urinary tract infections (UTIs) are common, but increasingly hard to treat because the bacteria that cause them are developing resistance to many antibiotics. Researchers headed by a team at the ...
