Where is Corynebacterium Xerosis found?
Corynebacterium xerosis is a commensal organism found in skin and mucous membranes of humans. It is considered an unusual pathogen, and it is rarely found in human and animal clinical samples.
How do you identify Corynebacterium Xerosis?
C. xerosis grows in colonies of 0.2–1.0 mm in diameter, brown-yellowish in colour, slightly dry in appearance and non-haemolytic when cultured in blood agar. Microscopically, C. xerosis is irregularly stained, pleomorphic Gram positive rods presenting club-like ends.
What disease does Corynebacterium Xerosis cause?
Corynebacterium xerosis has been reported as a rare but serious cause of bacteremia, septicemia, pneumonia, septic arthritis, vertebral osteomyelitis, meningitis and, most commonly, endocarditis in adults.
Is Corynebacterium Xerosis normal flora?

Is Corynebacterium Xerosis aerobic?
Structure and Physiology. This bacteria is a Gram positive, rod shaped aerobe.
Is Corynebacterium Xerosis aerobic or anaerobic?
Corynebacteria are chemoorganotrophic, aerobic, or facultatively anaerobic, and they exhibit a fermentative metabolism (carbohydrates to lactic acid) under certain conditions. They are fastidious organisms, growing slowly on even an enriched medium.

What is Corynebacterium in microbiology?
Corynebacterium (/kɔːˈraɪnəbækˌtɪəriəm, -ˈrɪn-/) is a genus of bacteria that are Gram-positive and most are aerobic. They are bacilli (rod-shaped), and in some phases of life they are, more specifically, club-shaped, which inspired the genus name (coryneform means “club-shaped”).
Is Corynebacterium Xerosis motile?
Distinctive features for the identification of C. xerosis include negative reactions for hemolysis, urease, and motility, and positive reactions for catalase, glucose, sucrose and nitrate reduction.
