Which among the following bacteria is microaerophilic?
Correct Answer: Campylobacter
Description: Campylobacter is a microaerophilic organism, which means it requires oxygen to survive, but requires environments containing lower levels of oxygen than are present in the atmosphere (~20% concentration). Campylobacter is a motile, non spore forming, curved, oxidase positive, gram negative rod. They have a polar flagella attached at their ends giving it 'S' shape. In contrast to the vibrios, it does not break down carbohydrates, but uses amino acids and metabolic intermediates for energy. Ref: Ray C.G., Ryan K.J. (2010). Chapter 32.
