Achromobacter xylosoxidans
Achromobacter xylosoxidans is a gram-negative bacteria species that is part of the Achromobacter genus. It is a pathogen that is known to cause various types of infections, particularly in individuals with compromised immune systems.
Taxonomy[edit | edit source]
The species name xylosoxidans is derived from the Greek words xylon, meaning wood, and oxidans, meaning oxidizing. This is in reference to the bacterium's ability to oxidize xylose, a type of sugar commonly found in wood.
Characteristics[edit | edit source]
Achromobacter xylosoxidans is a rod-shaped, motile bacterium. It is oxidase positive and can grow in the presence of up to 6% sodium chloride. The bacterium is also capable of nitrate reduction, a process that allows it to survive in environments with low oxygen levels.
Pathogenicity[edit | edit source]
Achromobacter xylosoxidans is an opportunistic pathogen, meaning it primarily causes infections in individuals with weakened immune systems. It has been associated with a variety of infections, including bacteremia, pneumonia, meningitis, and endocarditis. The bacterium is also a known cause of hospital-acquired infections, particularly in intensive care units.
Treatment[edit | edit source]
Treatment of Achromobacter xylosoxidans infections can be challenging due to the bacterium's inherent resistance to many commonly used antibiotics. However, it is generally susceptible to aminoglycosides, quinolones, and piperacillin-tazobactam.
