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 ...

Figure 1: Toll pathway activation in the absence of a functional PGRP-SA–GNBP1 receptor complex. Figure 2: Effects of PGRP-SD mutation on Toll pathway activation by Gram-positive bacteria. Figure 4: ...

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 ...

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 ...

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 ...

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 ...

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 ...

Compared with other urine analysis methods, urine Gram stain has a moderate predictive value for detecting gram-negative bacteria in urine culture but does not significantly improve urinary tract ...
