Case of flexor tenosynovitis caused by Mycobacterium arupense

Research output: Contribution to journalArticlepeer-review


Mycobacterium arupense is a member of the Mycobacterium terrae complex (MTC) that is implicated in bone and joint infections, among others. This group of environmental pathogens can be found in soil, reclaimed and drinking water systems, rodents, fish tanks and bioaerosols in duck houses. Interestingly, while M. arupense is genotypically closely related to the other agents in the MTC, antibiotic susceptibility of these mycobacteria can vary widely and empiric antibiotic therapy is controversial. Our case report contributes to the very limited literature on M. arupense tenosynovitis-as only six cases have been reported since 2008-and sheds light on different courses of treatment. While previous cases have been successfully treated, a streamlined course of therapy for M. arupense tenosynovitis is still needed.
