Overview

Mycobacterium immunogenum is a species of the phylum actinobacteria (Gram-positive bacteria with high guanine and cytosine content, one of the dominant phyla of all bacteria), belonging to the genus mycobacterium.

These non-tuberculous mycobacteria are sometimes found in fouling water-based cutting fluids, often causing hypersensitivity pneumonitis to the machinists in the affected grinding plants.^[2]

Type strain

Strain BH29 = MC 779 = ATCC 700505 = CCUG 47286 = CIP 106684

Treatment

Antimicrobial regimen

M. immunogenum isolates ^[3]

susceptible: Amikacin AND Clarithromycin but
resistant: Ciprofloxacin, Doxycycline, Cefoxitin, Tobramycin, and Sulfamethoxazole
NOTE: The optimal therapy for this organism is unknown; however, successful therapy is likely difficult due to the extensive antibiotic resistance of the organism
