Alcaligenes faecalis
Alcaligenes faecalis 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. Mode of transmission Contaminated medical devices and fluids (e.g., venous lines, haemodialysis, irrigation, disinfectants); often a contaminant. A faecalis may be isolated from blood, sputum, and urine, especially in immunocompromised hosts.Alcaligenes faecalis Acaligenes odorans, Pseudomonas odorans Bacteriology An environmental bacterium which colonizes moist areas in hospitals and may transiently colonize the skin Mode of transmission Contaminated medical devices and fluids–eg, IV, hemodialysis, irrigation, disinfectants; often a contaminant, A faecalis may be isolated from blood, sputum, and urine, especially in immunocompromised hostsAl·ca·lig·e·nes fae·ca·lis (al-kă-lij'ĕ-nēz fē-kā'lis) 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. [alkali + G. -gen, producing]Alcaligenes faecalisA species normally found in the human intestine. It has been associated with hospital-acquired septicemia and urinary tract infections.
