BACILLUS EPIDERMIDIS Meaning and
Definition
-
Bacillus epidermidis is a common non-pathogenic bacterium that belongs to the genus Bacillus. It is a facultative anaerobe, which means it is capable of survival and growth in both the presence and absence of oxygen. Bacillus epidermidis is also a gram-positive bacterium, indicating its thick cell wall structure that retains the crystal violet stain during the Gram staining method.
This bacterium is commonly found on the human skin, mucous membranes, and gastrointestinal tract as part of the normal human flora. It is regarded as an opportunistic pathogen, as it typically causes infections in individuals with compromised immune systems, such as those with underlying health conditions or patients with indwelling medical devices like catheters or prosthetic devices.
Despite its potential to cause infections, Bacillus epidermidis is generally considered harmless and commensal. It plays a crucial role in maintaining the balance of the skin microbiota and preventing the overgrowth of other harmful microorganisms. Moreover, its ability to produce a protective biofilm assists in its adherence to artificial surfaces, contributing to its involvement in medical device-associated infections.
In laboratory settings, Bacillus epidermidis is widely studied and utilized as a model organism for various research purposes. Its genome and physiology are being extensively investigated to better understand its colonization and survival strategies, as well as to develop effective preventive and treatment approaches against pathogenic bacteria related to Bacillus epidermidis.
Etymology of BACILLUS EPIDERMIDIS
The term "Bacillus epidermidis" has its etymology rooted in Latin and Greek.
The word "Bacillus" originates from the Latin word "bacillum", meaning a little staff or wand. It refers to the rod-like shape of the bacteria in this genus.
"Epidermidis" comes from the Greek words "epi" meaning on or upon, and "dermis" meaning skin. Thus, "Bacillus epidermidis" can be understood as a rod-shaped bacterium that resides on the skin.
