What is Achromobacter pneumonia?
Achromobacter xylosoxidans, subspecies denitrificans, is a gram-negative rod recently implicated as an emerging cause of infection in both immunosuppressed and immunocompetent populations. Few cases are reported in literature involving multiple body systems.
What causes Achromobacter?
Transmission mainly occurs through contact with contaminated liquids, for example, intravenous solutions, mouthwashes or soap solutions. Improperly reprocessed wipes dispenser systems can also be a source of infection. An infection with Achromobacter xylosoxidans tends to occur only rarely.
Is Achromobacter aerobic or anaerobic?
Although classified as aerobic organisms, Achromobacter species may also thrive in anaerobic environments. The organisms have a global distribution, and may be found in both fresh and brackish bodies of water, as well as municipal and hospital water supplies.
How is achromobacter Xylosoxidans treated?
Trimethoprim-sulfamethoxazole, ceftazidime, piperacillin, and carbapenems are the most active agents against Achromobacter isolates.
Is achromobacter an Enterobacteriaceae?
Achromobacter is a genus of bacteria, included in the family Alcaligenaceae in the order Burkholderiales. The cells are Gram-negative straight rods and are motile by using one to 20 peritrichous flagella….

How is achromobacter treated?
How is Achromobacter Xylosoxidans treated?
Where is Achromobacter found?
Achromobacter species are nonfermenting gram-negative bacilli found in soil and water, including swimming pools, well water, dialysis solutions, and chlorhexidine solutions. They can occasionally be recovered from the respiratory and gastrointestinal tracts, primarily in persons with health care contact.
What antibiotics cover achromobacter?
Is achromobacter motile?
Achromobacter are non-motile, non-pigmented aerobic rods associated with spoilage of meats. They are catalase and oxidase positive (Table 23.1).
Is achromobacter gram positive?
Achromobacter is a genus of bacteria, included in the family Alcaligenaceae in the order Burkholderiales. The cells are Gram-negative straight rods and are motile by using one to 20 peritrichous flagella. They are strictly aerobic and are found in water (fresh and marine) and soils.
What is the difference between Achromobacter and xylosoxidans?
Achromobacter signifies colorless rodlet and xylosoxidans implies oxidizing xylose. Although Achromobacter strains had been previously described, Yabuuchi and Ohyama were the first to isolate Achromobacter xylosoxidans from ear discharge. Colonies are circular, flat to convex, smooth, and have an entire margin.
What kind of rod does xylosoxidans have?
A. xylosoxidans is a Gram-negative rod that does not form spores. It is motile, with peritrichous flagella that distinguish it from Pseudomonas species, and is oxidase-positive, catalase-positive, and citrate-positive.
What kind of rod does Achromobacter spp have?
Achromobacter spp. and Alcaligines spp. are gram-negative, oxidase- and catalase-positive, indole-negative nonfermenting rods, strictly aerobic and motile, with one to eight peritrichous flagella.
What’s the difference between Achromobacter and Alcaligenes?
After it was discovered the only difference between the Alcaligenes and Achromobacter motile strains was the reaction in litmus milk, the genus name Alcaligenes was changed to Achromobacter. Achromobacter signifies colorless rodlet and xylosoxidans implies oxidizing xylose.
