ARCANOBACTERIUM Meaning and
Definition
-
Arcanobacterium refers to a genus of gram-positive bacteria belonging to the family Actinomycetaceae. These bacteria are anaerobic or facultative anaerobic in nature, implying that they have the ability to grow in environments with or without oxygen. The genus Arcanobacterium consists of several species, including Arcanobacterium haemolyticum, Arcanobacterium pyogenes, and Arcanobacterium phocae.
Arcanobacterium species are commonly found in the oral cavity, upper respiratory tract, and genital tract of humans and animals. These bacteria are known to be opportunistic pathogens, meaning they typically cause infections in individuals with weakened immune systems or those suffering from underlying medical conditions. Arcanobacterium haemolyticum, in particular, is associated with causing an illness called pharyngitis, which is characterized by a sore throat, fever, and the production of a specific toxin that causes a distinctive rash.
These bacteria are often implicated in various infections including wound infections, abscesses, cellulitis, and endocarditis. Diagnosis of Arcanobacterium infections is typically made by obtaining clinical specimens from the affected site and conducting microbiological tests such as culture and identification of the bacteria.
Treatment for infections caused by Arcanobacterium species usually involves the use of antibiotics, such as erythromycin or penicillin, which are effective against gram-positive bacteria. However, the choice of antibiotic may depend on the specific strain and its antibiotic susceptibility.
Etymology of ARCANOBACTERIUM
The word "arcanobacterium" is derived from the combination of two main components: "arcano" and "bacterium".
1. "Arcano" is derived from the Latin word "arcanum", which means secret or mystery. It is typically used to refer to something hidden or concealed. In the context of "arcanobacterium", it implies the hidden or secretive nature of this bacterium.
2. "Bacterium" is a term derived from the Greek word "baktḗrion", meaning small rod or staff. It refers to a type of microorganism that may cause diseases or have various other effects.
Thus, "arcanobacterium" essentially denotes a bacterium with secretive or hidden characteristics.
