Description:Under the low-power magnification of 10X of a digital Keyence scope, this photograph depicts the colonial growth displayed by Gram-negative Achromobacter xylosoxidans bacteria, which were cultured on Thayer-Martin (TM) agar medium, for a 72 hour time period, at a temperature of 37°C.
Recently, Achromobacter xylosoxidans, formerly Alcaligenes xylosoxidans, has been found inhabiting the lungs of cystic fibrosis (CF) patients. This bacterium has also proven to be “innately resistant to many antimicrobial drugs (2), except piperacillin, piperacillintazobactam, and imipenem, and moderately susceptible to ceftazidime (45% of susceptible isolates), which is widely used to treat infection due to Pseudomonas aeruginosa(3,4). (Article 1, below) A. xylosoxidans is often encountered as an inhabitant of aqueous environments, which have included swimming pools, dialysis fluids, and in distilled, deionized, and tap water. (Article 2, below) See the articles below for additional information regarding Achromobacter xylosoxidans.
