Reuters Collectively, the defendants accused of raping Gisèle Pelicot are facing more than 600 years in jail They are young, old, burly, thin, black and white. Among them are firefighters, lorry drivers, soldiers, security guards, a journalist and a DJ. These are the 50 men accused of raping Gisèle Pelicot at the behest of her husband, Dominique Pelicot, 72, who drugged her for a decade with prescription sleeping pills.

Next week they are due to be sentenced, at the end of a trial that started in September. If found guilty, collectively they face more than 600 years in jail.

Bacteria are microscopic organisms found everywhere – in soil, water, plants, animals, and humans. They are classified into two main groups based on the structure of their cell wall: Gram-positive and Gram-negative bacteria. This classification is done using a scientific method called Gram staining, which reveals specific characteristics of the bacterial cell wall. What is Gram Staining? Gram staining is a laboratory technique used to identify bacteria by staining their cell walls. The bacteria either appear purple or pink depending on their cell wall structure. Gram-Positive Bacteria Gram-positive bacteria have a thick layer of peptidoglycan in their cell walls, which gives them strength and stability. These bacteria also contain teichoic acids, which help in cell wall maintenance.
