What is the morphology of Alcaligenes faecalis?
What is the morphology of Alcaligenes faecalis?
Curved, straight or bean-shaped: bacilli come in many variants and are widely spread. Alcaligenes faecalis is a Gram-negative, rod-shaped bacterium with flagella, and belong to the family of Alcaligenaceae.
What is the cell shape of Mycobacterium Phlei?
phlei is a rod-shaped bacterium 1.0 to 2.0 micrometers in length. If grown on an agar plate, M. phlei colonies appear orange to yellow in color, and predominantly dense with smooth edges, although some smaller filamentous colonies have also been described. Like other mycobacteria, M.
What is the size of Alcaligenes faecalis?
Alcaligenes faecalis occur in water and soil. The microbe has peritrichous flagellar arrangement which allows for motility (2). It is a gram-negative, rod-shaped organism observed at 0.5-1.0 μm x 0.5-2.6 μm in diameter.
Is Alcaligenes faecalis Gram positive or negative?
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 Alcaligenes faecalis pathogenic or nonpathogenic?
Alcaligenes faecalis is usually non-pathogenic, but cases of endocarditis, meningitis, peritonitis, and abscesses have been reported [26]. Most infections have been nosocomial, and most commonly occur in those who are immunocompromised as a result of contamination of hospital equipment [26].
Is Alcaligenes faecalis Enterobacteriaceae?

Is Mycobacterium Phlei aerobic or anaerobic?
phlei, M . gordonae and M. kansasi in aerobic conditions only. Anaerobic cultures of both slowly and rapidly growing mycobacteria were sensitive to malachite green.

Is Alcaligenes faecalis an opportunistic pathogen?
Alcaligenes faecalis is usually causes opportunistic infections in humans. Alcaligenes faecalis infection is often difficult to treat due to its increased resistance to several antibiotics.
What is the genus of Alcaligenes faecalis?
Alcaligenes
Alcaligenes faecalis/Genus
What is Alcaligenes faecalis?
Alcaligenes faecalis is a species of Gram-negative, rod-shaped bacteria commonly found in the environment. It was originally named for its first discovery in feces, but was later found to be common in soil, water, and environments in association with humans.
What are the characteristics of Agrobacterium faecalis?
It is alpha-hemolytic and requires oxygen. A. faecalis can be grown at 37 °C, and forms colonies that lack pigmentation. The bacterium degrades urea, creating ammonia which increases the pH of the environment.
What is the flagellar arrangement of a Enterococcus faecalis?
The microbe has peritrichous flagellar arrangement which allows for motility (2). It is a gram-negative, rod-shaped organism observed at 0.5-1.0 μm x 0.5-2.6 μm in diameter. An aerobic microbe, A. faecalis is optimal at temperatures between 20-37 °C (11).
Is Alcaligenes faecalis an autotrophic or heterotrophic nitrifier?
The growth of autotrophic nitrifiers is very slow requiring a long hydraulic retention time in treatment plants. Alcaligenes faecalis has been identified as a heterotrophic nitrifier and aerobic denitrifier and converts ammonium into denitrification products simultaneously.
