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 ...

Gram-negative meningitis is a form of meningitis. The term gram-negative refers to a way of differentiating bacteria. This type of bacteria is typically resistant to drugs and most available ...

• Require X (hemin) and/or V (nicotinamide adenine dinucleotide) factors for growth • Responsible for 0.5–1% of all cases of IE • Haemophilus aphrophilus is the most common species responsible for IE ...

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, ...

Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis, while sparing healthy microbes in the mouse ...

A team led by Paul Hergenrother at the University of Illinois Urbana-Champaign has discovered a new antibiotic that exclusively targets gram-negative bacteria and avoids wiping out the ecosystem of ...

Vancomycin is a common antibiotic used to treat gram-positive bacterial infections. It targets a key building block of the bacterial cell wall called Lipid II, but it can’t reach this lipid in ...

Clostridium perfringens is a spore-forming bacteria that can function without oxygen (anaerobic bacteria). These gram-positive bacteria are typically found in human and animal intestines. Bacteria are ...

Animals house thousands of commensal bacterial species in their guts, which play an important role in maintaining the host’s health. 1 However, antibiotic treatment indiscriminately wipes out both ...
