Mycobacterium florentinum is a strain of bacteria found in humans that can cause infections and other disease conditions, and prolong sickness. It presents a high resistance to antimycobacterial drugs. It is characterized by: slow growth and a short helix 18 in the 16S rDNA.

Etymology: florentinum, of the Italian city of Florence, where the majority of the strains were collected and investigated.

Type strain

First isolated and characterized in Florence, Italy. Strain FI-93171 = CCUG 50992 = CIP 108409 = DSM 44852
