A cell wall provides the bacterial cell sturdiness and helps maintain its shape and internal pressure. However, there are some key differences between the two classes of bacteria. First, gram-negative ...

Many gram-negative bacteria are pathogenic, like Pseudomonas aeruginosa, and E. coli, and can evade antibiotics. Researchers have wanted to know more about disrupting the gram-negative cell wall ...

IntroductionPenicillin-binding proteins (PBPs) synthesize and remodel the peptidoglycan layer of the bacterial cell wall, ...

Spheroplasts are created from gram-negative bacteria and only part of their cell walls are removed. Gram-positive bacteria have only one cytoplasmic membrane, while gram-negative bacterium have ...

Mechanisms of resistance. Resistance can be either inherent -- as exemplified by the inability of vancomycin to penetrate the cell wall of gram-negative bacteria -- or acquired.

A transporter which some bacteria use to recycle fragments of their cell wall has been discovered by researchers at Umeå university, Sweden. They found that the transporter controls resistance to ...
