Researchers knew NAIPs were responsible for detecting Salmonella Typhimurium, Pseudomonas aeruginosa and other gram-negative bacteria in macrophages, and ... NLRC4 is unique because it is activated solely to fight gram-negative bacteria, particularly Salmonella, Legionella and Pseudomonas.
In particular, a class of bacteria called 'Gram-negative bacteria,' which include the well-known species E. coli, are causing major problems in our hospitals. The problem is that most antibiotics that we know today work according to only a few mechanisms of action and so when a bacterium becomes tolerant to one ...

Genentech researchers have found a chink in the armor of drug-resistant, gram-negative bacteria called the BamA enzyme, which is found in the bugs' outer membrane. And they've found a way to attack this protein with an antibody--an approach that they say could pave the way for a new class ...

In the late 1800s, bacteriologist Hans Christian Gram discovered a way to classify bacteria, most of which fall into one of two groups: Gram-positive or Gram-negative. He developed a stain, still in use today, which bacteria either absorb or repel. Gram-positive, with their adsorbent cell wall, glow violet, flush ...
Gram staining is dependent on the interaction between the negatively charged surface of bacteria and the positive ions within common stains. Gram negative bacteria are often pathogenic and contain endotoxins within their outer membranes. The cell wall structure of Gram negative bacteria also confers an increased ability ...
Compared with antibiotics, nano-antibacterial agents have the following two advantages: i) broad-spectrum bactericidal effects against Gram-positive and Gram-negative bacteria and ii) long-lasting bactericidal effects on the prevention of bacterial growth due to their extraordinary stability. Significant ...
Bacteria have long been a prolific source of potentially therapeutic natural products. But scientists estimate that only about 1% of bacteria can be grown in the lab, making most unavailable for drug discovery. As a result, scientists have largely abandoned screening microbes to find new antibiotics and other ...
“The primary advantages in Defender is it's effective against both gram-negative and gram-positive bacteria,” he says. “It can be used at a very high rate, unlike antibiotics, which have a GRAS (generally recognized as safe) of one part per million, while ours can be used at 173 (parts per million). Because ...
