Caused by or produced from bacilli; originating from rod-shaped bacteria.
From bacillus + -genic (Greek -genes, 'producing' or 'caused by'). The -genic suffix attaches to names of organisms to indicate something is produced by them.
Tuberculosis is the classic bacilligenic disease—for centuries people didn't know it was caused by a specific bacillus until Robert Koch identified it under a microscope.
