Causes

It is caused by Klebsiella rhinoscleromatis—subspecies of Klebsiella pneumoniae— a gram-negative, encapsulated, nonmotile, rod-shaped bacillus (diplobacillus), member of the Enterobacteriaceae family. It is sometimes referred to as the "Frisch bacillus," named for Anton von Frisch who identified the organism in 1882. It is contracted directly by droplets or by contamination of material that is subsequently inhaled.
