Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories ...

Researchers from the National University of Singapore (NUS) have solved a 60-year-old mystery in bacterial cell envelope ...

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 ...

In gram positive bacteria, the large crystal violet-iodine complexes are then unable to penetrate and escape the thick peptidoglycan layer, resulting in purple stained cells. However, in gram negative ...

Gram-negative bacteria are harder to kill because of their harder cell wall. When their cell wall is disturbed, gram-negative bacteria release endotoxins that can make your symptoms worse.

Gram-negative cells, such as E. coli, have a thin peptidoglycan layer sandwiched between a porous outer membrane and an inner membrane. How gram staining really works.

Gram-positive bacteria are bacteria with thick cell walls. In a Gram stain test, these organisms yield a positive result. Here’s why knowing whether the result is positive or negative is important.
