Bacterial artificial chromosome: A laboratory creation involving an artificially constructed chromosome in which medium-sized segments of DNA (100,000 to 300,000 bases in length) that come from another species are cloned into bacteria. Once the foreign DNA has been cloned into the bacteria’s chromosome, many copies of it can be made (amplified) and sequenced.
Bacterial artificial chromosome is abbreviated BAC.

- Bacterial vaginosis
A vaginal condition characterized by an abnormal vaginal discharge due to an overgrowth of normal bacteria in the vagina. Women with bacterial vaginosis also have fewer than the usual population of vaginal bacteria, called lactobacilli. Symptoms of bacterial vaginosis are vaginal discharge and sometimes a fishy odor. A microscopic sign of bacterial vaginosis is an […]
Bacteriaphobia: An abnormal and persistent fear of germs. Sufferers from bacteriaphobia experience undue anxiety even though they realize that most germs are not pathogens (disease-causing germs). To avoid germs, they may repeat cleaning rituals, such as washing their hands or face. (Surgeons may do well to have a mild degree of bacteriaphobia.) “Bacteriaphobia” is derived […]
Bacteriocidal: Capable of killing bacteria. Antibiotics, antiseptics, and disinfectants can all be bacteriocidal.
