Curved, straight or bean-shaped: bacilli come in many variants and are widely spread.

Alcaligenes spp. /
Achromobacter spp.

Alcaligenes spp./Achromobacter spp.comprise Gram-negative, rod-shaped bacteria with flagella, which belong to the family of Alcaligenaceae. The bacteria may trigger bloodstream infection, peritonitis and meningitis in immunosuppressed people. Alcaligenes/Achromobacter bacteria possess natural resistance to all cephalosporins and often to aminoglycosides and aztreonam, too.

The transmission mainly occurs via direct or indirect contact and droplet infection, e.g. through contaminated nebulisers and ventilation equipment.
