This 2008 scanning electron microscopic (SEM) image depicts the lumen of a central venous catheter, removed from an asymptomatic patient. The biofilm contained the rod-shaped bacteria, Alcaligenes xylosoxidans in association with fibrin-like material on the catheter’s surface. This image accompanied the Emerging Infectious Diseases® journal article entitled, ”Alcaligenes xylosoxidans Bloodstream Infections in Outpatient Oncology Office”, by Moon J. Kim, et al. See a link to the article below. Alcaligenes xylosoxidans, also known as Achromobacter xylosoxidans, is a Gram-negative, water-borne organism that causes healthcare-associated infections, and bacteremia in immunocompromised patients with indwelling catheters; it can also contaminate liquids. A. xylosoxidans is found in soil and water, and grows in saline.
