Is Alcaligenes faecalis motile?

Is Alcaligenes faecalis motile?

Alcaligenes faecalis is a Gram-negative catalase- and oxidase-positive, motile rod. It is commonly found in a watery environment and is rarely isolated from humans.

Is Alcaligenes faecalis aerobic or anaerobic?

Alcaligenes faecalis is an aerobic bacillus known to inhabit soil and water environments (5).

Is alcaligenes aerobic?

Alcaligenes are Gram-negative, aerobic bacteria although some strains are capable of anaerobic respiration in the presence of nitrite or nitrate.

What does Alcaligenes faecalis cause?

Alcaligenes faecalis is a Gram-negative, rod-shaped bacterium with flagella, and belong to the family of Alcaligenaceae. Particularly in immunosuppressed people, the opportunistic pathogen may trigger local infections, including peritonitis, meningitis, otitis media, appendicitis, and bloodstream infection.

Is Alcaligenes faecalis harmful to humans?

Alcaligenes faecalis is a species of gram-negative, rod-shaped, aerobic bacteria commonly found in the environment. A. faecalis-associated nosocomial infections are common in hospitalized patients, but serious life threatening infections are rare.

What is Alcaligenes faecalis resistant to?

Alcaligenes faecalis is generally resistant to aminoglycosides, chloramphenicol and tetracyclines and usually susceptible to trimethoprim–sulfamethoxazole and β-lactam antibiotics such as ureidopenicillins, ticarcillin–clavulanic acid, cephalosporins and carbapenems.

Does Alcaligenes faecalis reduce nitrate?

faecalis could not reduce nitrate, at three poised potentials of +0.06, −0.06, and −0.15 V (versus normal hydrogen electrode [NHE]), the nitrate was partially reduced with −0.15- and −0.06-V potentials at rates of 17.3 and 28.5 mg/liter/day, respectively.

Is a faecalis Alkaliphile?

faecalis could still slightly show pH tolerance. The acid tolerance response is related to the ability of certain E. faecalis strains to grow in environments with an alkaline pH (9.5–12) within 48–72 hours 12. In general, E.

Where are Alcaligenes faecalis 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].

Is a faecalis urease positive?

It is positive by the oxidase test and catalase test, but negative by the nitrate reductase test.

What does Alcaligenes faecalis smell like?

The distinctive properties of an Alcaligenes-like organism isolated from human pathological material are described. The organism is readily recognizable by its characteristic colonial appearances, fruity smell and greening of blood agar.

What bacteria smells like butterscotch?

Streptococcus anginosus may be beta-hemolytic or nonhemolytic. The small colonies often give off a distinct odor of butterscotch or caramel.
