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 ...

A flexible microplasma discharge device (MDD) was successfully developed for inactivating multi-drug resistant Gram-negative (Escherichia coli, Pseudomonas aeruginosa) and Gram-positive ...

Gram negative bacteria are often pathogenic and include Escherichia coli, a common cause of food poisoning and Vibrio cholerae, the waterborne pathogen responsible for cholera outbreaks.

Over time, bacteria can become resistant to the antibiotics that once killed them. The most dangerous today are resistant Gram-negative bacteria, which have stronger structural defenses.

Published by Hans Christian Gram in 1884, gram staining distinguishes gram-positive bacteria (purple) from gram-negative bacteria (pink). Gram-positive critters, such as staph, have a thick ...
