| Description | Corynebacterium striatum is a gram-positive, rod-shaped bacterium that thrives optimally at mesophilic temperatures, identifying it as a facultative anaerobe and a chemoheterotroph. This microbe belongs to the family Corynebacteriaceae and is commonly found in various body sites across humans, including the skin, respiratory tract, and urogenital area. These locations make it a notable member of the human microbiome, usually present as part of the normal flora, with specific prominence in areas that are warm and moist. The gram-positive nature of Corynebacterium striatum indicates a thick peptidoglycan layer in its cell wall, which provides structural integrity and protection against environmental stresses. The rod shape, or bacillary form, is characteristic of many bacteria and facilitates its mobility and colonization ability. As a facultative anaerobe, this microbe can switch between aerobic respiration, when oxygen is present, and fermentation or anaerobic respiration when oxygen levels are low, thus adapting to various environmental conditions. As a chemoheterotroph, Corynebacterium striatum derives energy and carbon from organic compounds, primarily utilizing sugars and amino acids available in its niche. Its presence in the human body is generally benign, but it can become pathogenic under certain conditions, particularly in immunocompromised individuals, leading to opportunistic infections. Notably, its ability to form biofilms on medical devices and within tissues enhances its virulence, complicating treatment options. Additionally, Corynebacterium striatum has been recognized for its potential role in antimicrobial resistance, raising concerns for healthcare settings where it can pose challenges due to its resistance to multiple antibiotic classes. |
