Infectious bacteria are growing increasingly resistant to drugs, which is becoming a serious threat to public health worldwide. Bacteria can be classified based on various characteristics, such as by ...

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 ...

UNTIL recently it had been assumed on the basis of earlier work that the amino-acid composition of the mucopeptide in Gram-positive bacteria always included either αɛ-diaminopimelic acid or lysine.

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 ...
