How Do You Spell BACILLUS ACNES CONTAGIOSAE?

Bacillus acnes contagiosae is a Gram-positive bacterium that is commonly found on human skin. It is a rod-shaped bacterium belonging to the Bacillus genus and specifically among the Propionibacterium species. The term "Bacillus acnes contagiosae" is not frequently used in modern scientific literature, and it may refer to a specific strain or variant of the bacterium Propionibacterium acnes, which is now typically used to designate this species.

Propionibacterium acnes is an anaerobic bacterium that is part of the normal microbiota on the skin of humans and animals. It is involved in various health conditions, including acne vulgaris, which is a common skin disorder affecting many individuals during adolescence and early adulthood.

Despite its name, P. acnes is generally considered to be non-contagious, as it is a commensal bacterium rather than a pathogen. It typically resides within hair follicles and sebaceous glands, where it feeds on sebum. In some cases, however, it can become pathogenic and trigger inflammation and infection, leading to conditions such as acne vulgaris.

In conclusion, "Bacillus acnes contagiosae" likely refers to a specific strain or variant of the bacterium Propionibacterium acnes. However, the more commonly used term in current scientific literature is Propionibacterium acnes, a Gram-positive, anaerobic bacterium that is commonly found on human skin and can be associated with skin conditions such as acne vulgaris.
