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?
Characteristics. Achromobacter are non-motile, non-pigmented aerobic rods associated with spoilage of meats.
Is Achromobacter a fermenter?
Achromobacter xylosoxidans (A. xylosoxidans) is a catalase-positive, oxidase-positive, and glucose-non-fermenting Gram-negative rod. Non-fermenting Gram-negative rods have similar properties and are difficult to differentiate.
Is alcaligenes the same as Achromobacter?
Alcaligenaceae. Both Achromobacter and Alcaligenes spp., along with the closely related Bordetella spp., currently are grouped together within the family Alcaligenaceae. The clinically relevant Achromobacter and Alcaligenes spp.
What antibiotic treats Achromobacter?
Trimethoprim-sulfamethoxazole, ceftazidime, piperacillin, and carbapenems are the most active agents against Achromobacter isolates.
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.
Is achromobacter anaerobic?
Achromobacteria are ubiquitous, lactose- nonfermenting, gram-negative bacilli found in aquatic environments and soil. Although classified as aerobic organisms, Achromobacter species may also thrive in anaerobic environments.
Does Alcaligenes faecalis have a capsule?
faecalis was isolated in 1896 by Petruschky from stale beer. Several strains of the organism have been found since then. This species is motile, flagellated, slender, slightly curved, not spore-forming, slowly growing, nonfermenting, capsule forming, Gram-negative aerobe of the family Alcaligenaceae.
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….

Where can Alcaligenes faecalis be found?
Alcaligenes faecalis (A. faecalis) is a Gram-negative, obligate aerobic, oxidase-positive, catalase-positive, and nonfermenting bacterium. It is commonly found in soil, water, and in hospital settings, such as in respirators, hemodialysis systems, and intravenous solutions [1, 2].
What kind of organism is Achromobacter xylosoxidans and what does it do?
Achromobacter xylosoxidans (formerly Alcaligenes xylosoxidans) is a Gram-negative, aerobic, oxidase and catalase-positive, motile bacterium with peritrichous flagella, from the genus Achromobacter. It is generally found in wet environments.
Which is the most common clinical presentation of Achromobacter?
Pneumonia and bacteremia are the two most common clinical presentations of Achromobacterinfections in non-CF hosts (26). Infections of the skin and soft tissue, urinary tract, intraabdominal organs, central nervous system (CNS), eye, and ear are less frequently reported, endocarditis and bone infections being very rare (27,–34).
When was the genus of Achromobacter first established?
INTRODUCTION Genus Achromobacterwas first established in 1923 by the Committee of the Society of American Bacteriologists (today the American Society for Microbiology) as “non-pigment-forming, motile or nonmotile Gram-negative bacteria occurring in water and soil” (1).
What are the symptoms of xylosoxidans bacteremia?
He subsequently experienced 13 other documented episodes of A. xylosoxidans bacteremia. These episodes were each associated with multiple symptoms, including low-grade fever, headache, nausea, diarrhea, hematochezia, abdominal distension, and dizziness.
