Is Alcaligenes aerobic?
Alcaligenes are Gram-negative, aerobic bacteria although some strains are capable of anaerobic respiration in the presence of nitrite or nitrate. They are catalase and oxidase positive.
Is Alcaligenes a lactose fermenter?
Abstract. Stenotrophomonas maltophilia, Burkholderia cepacia complex, Elizabethkingia spp., Chryseobacterium spp., Achromobacter spp., and Alcaligenes spp. are less-common non–lactose-fermenting bacteria that have emerged as important opportunistic pathogens.
Is Alcaligenes faecalis obligate Aerobe?
A bacillus which is a motile, non-nitrate reducing, oxidase positive, catalase positive, and citrate positive gram-negative obligate aerobe that colonises humid areas in hospitals and may transiently colonise the skin.
Is P vulgaris gram positive?
Proteus vulgaris Proteus vulgaris is an facultative anaerobe, rod-shaped, Gram-negative bacterium in the Enterobacteriaceae family. It causes urinary tract and wound infections.
Is Pseudomonas aeruginosa aerobic or anaerobic?
Pseudomonas aeruginosa had been considered as an obligately aerobic bacterium previously, but it is now recognized to be highly adapted to anaerobic conditions.
Is Alcaligenes faecalis VP positive?
*Test for oxidase activity Alcaligenes faecalis, used for an earlier test, is oxidase positive and Escherichia coli is oxidase negative.
What diseases does Alcaligenes faecalis cause?
A. faecalis has been associated with endocarditis, bacteremia, meningitis, endophthalmitis, skin and soft tissue infections, urinary tract infections, otitis media, peritonitis, and pneumonia [1, 2, 7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28].
What disease does Alcaligenes faecalis cause?
A. faecalis has been associated with endocarditis, bacteremia, meningitis, endophthalmitis, skin and soft tissue infections, urinary tract infections, otitis media, peritonitis, and pneumonia [1, 2, 7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28]. A.
Is P. vulgaris aerobic or anaerobic?
Proteus vulgaris Proteus vulgaris is an facultative anaerobe, rod-shaped, Gram-negative bacterium in the Enterobacteriaceae family. It causes urinary tract and wound infections. In recent years, the resistances to many antibiotic classes (also beta-lactams) has significantly increased.
Where is the genus Alcaligenes located in the world?
Alcaligenes is phylogenetically located among the beta subgroup of proteobacteria, which also contains the genus Pseudomonas. Therefore it is not surprising that species in this genus are quite metabolically diverse like the pseudomonads.
Which is the related genus Achromobacter or Alcaligenes?
Alcaligenes piechaudii now is placed in the related genus Achromobacter as A. piechaudii. The status of A. xylosoxidans subsp. denitrificans as a member of the genus Alcaligenes or Achromobacter is currently under question.
How are Alcaligenes used in the real world?
Lab-scale experiments have been performed using engineered strains of Alcaligenes able to catabolize xenobiotic compounds, as well as remove metals. In this case, the bacteria are able to consume the contaminating xenobiotic as sole carbon source, thus reducing the cost of providing an outside substrate.
What kind of infections can Alcaligenes cause?
Systemic infection with this organism is very uncommon. It has been reported to cause sepsis, meningitis, peritonitis, enteric fever, appendicitis, cystitis, chronic suppurative otitis media, abscesses, arthritis, pneumonitis, and endocarditis.
