Light microscope images of E. coli cells in transmitted light (left) and reflected light that picks up the red fluorescence of a dye staining the cells' DNA (right). In normal cells (upper panel ...

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 ...

Escherichia coli is an example of a common Gram negative bacterium. Gram stain procedure. The Gram stain procedure was developed by Hans Christian Gram in the 1800s and was one of the first ...

The potentially deadly bug E-coli will come under the microscope today at an international conference. Leading scientists are among those attending the Food Micro 2008 event in Aberdeen, which ...

The team demonstrated the technology's effectiveness using bacterial samples containing both Gram-positive and Gram-negative bacteria (Listeria innocua and Escherichia coli). The virtual staining ...

A new compound has killed antibiotic resistant gram-negative bacteria, including E. coli, during tests. A new compound which visualises and kills antibiotic resistant superbugs has been discovered ...

A cheap holographic microscope capable of detecting E. coli and other bacteria has been developed by researchers in the US. The handheld device uses a laser instead of lenses to identify bugs in ...

Hans Christian Gram, the inventor of the Gram staining technique, was a pioneering biologist who devised the system of classification which led to as many as 30,000 formally named species of ...
