From Dorland's Medical Encyclopedia:
Alcaligenes (Al·ca·lig·e·nes) (al²k[schwa]-lij¢[schwa]-n[emacr]z) [Arabic al-qualy potash + Gr. gennan to produce] a widespread genus of gram-negative, aerobic, rod-shaped, alkaline-producing bacteria of uncertain affiliation, found in the intestines of vertebrates and as part of the normal skin flora, and occasionally the cause of opportunistic infections.
Alcaligenes denitri¢ficans, a species isolated from a variety of clinical specimens.
Alcaligenes faeca¢lis, a species isolated from hospital environments and from blood, sputum, and urine specimens. It is a cause of nosocomial
septicemia in immunocompromised patients, generally arising from contaminated hemodialysis or intravenous fluids. Called also A. odorans and
Bacterium faecalis alcaligenes.
The last one says it could be from contaminated hospital IV fluids!
Probably temporary if it is the last one.
