Gram-negative bacteria pose a significant threat to global health due to their high resistance to antibiotics compared to that of Gram-positive bacteria. Their formidable defensive capabilities stem ...

Pili are filamentous surface structures that play a key role in the adhesion, colonisation and biofilm formation of Gram-positive bacteria. These multiprotein appendages are assembled through a highly ...

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 ...

Researchers at Washington University School of Medicine in St. Louis developed a novel compound that effectively clears Gram-positive bacterial infections in mice, in particular skin and soft tissue ...

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 gut ...

Gram-negative bacteria's thick outer membrane prevents entry of toxic molecules, including antibiotics. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to ...

With delicate hues of purple and pink, a lab technique called gram staining has reliably characterized bacteria for more than a century. Yet many scientists are mistaken about why the vivid method ...

Gram staining is a type of differential staining used to distinguish between Gram positive and Gram negative bacterial groups, based on inherent differences in their cell wall constituents. Stains ...

Engineers at the University of California San Diego have developed a spray-on polymer coating that could help plants resist harmful bacterial infections and survive drought. The advance, published in ...

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 ...
