Alcaligenes

 [al″kah-lij´ĕ-nēz]
a genus of gram-negative, aerobic, rod-shaped bacteria, found in the intestines of vertebrates, as part of the normal skin flora, and in dairy products. Occasionally it causes opportunistic infections, A. faeca´lis being a cause of nosocomial septicemia in immunocompromised patients.

Alcaligenes

(al-kā-lij'en-ēz),
A genus of gram-negative, rod-shaped, nonfermenting bacteria (family Achromobacteraceae) that are either motile and peritrichous or nonmotile. They are strictly aerobic; some strains are capable of anaerobic respiration in the presence of nitrate or nitrite; their metabolism is respiratory, never fermentative; they do not use carbohydrates. Found mostly in the intestinal canal, decaying materials, dairy products, water, and soil; they can be isolated from human respiratory and gastrointestinal tracts and wounds in hospitalized patients with compromised immune systems; occasionally the cause of opportunistic infections, including nosocomial septicemia. Type species is Alcaligenes faecalis.
[alkali + G. -gen, producing]

The dramatic improvement in the survival of patients with cystic fibrosis (CF) has been complicated by the development of highly resistant strains of Pseudomonas aeruginosa and Staphylococcus aureus; the appearance of new virulent pathogens, such as Burkholderia cepacia; and the emergence of organisms of undetermined clinical importance, such as Alcaligenes xylosoxidans, Stenotrophomonas maltophilia, and the nontuberculous mycobacteria (NTM) (1-4).
The most tow successful strains able to degrade both phenol and PHA were characterized by stander criteria as Alcaligenes xylosoxidans subsp.
