Alcaligenes faecalis is a Gram-negative, rod-shaped bacterium with flagella, and belong to the family of Alcaligenaceae. Particularly in immunosuppressed people, the opportunistic pathogen may trigger local infections, including peritonitis, meningitis, otitis media, appendicitis, and bloodstream infection.
The bacterium is known to be resistant to all cephalosporins and often to aminoglycosides, aztreonam and cotrimoxazol.
The transmission commonly occurs via droplets and contact, e.g. via nebulisers and ventilation equipment. Contact infections via contaminated wash lotions have been reported as well.
