Mycobacterium farcinogenes infection after fracture repair of the tibia and fibula

Soft tissue infection and osteomyelitis caused by Mycobacterium farcinogenes after heart surgery: Case report and literature review of human cases

Mycobacterium farcinogenes (M. farcinogenes) is rapidly growing mycobacterium, belonging to non-tuberculous mycobacterial (NTM). M. farcinogenes is an exceedingly rare causative agent of human infection. Only seven cases with M. farcinogenes infections in humans were reported. This is a case of soft tissue infection and osteomyelitis caused by M. farcinogenes after heart surgery. Microbial identification was achieved by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The clinical outcome was favorable after surgical debridement and 4-month antibiotics treatment. We also provide a comprehensive literature review on this disease.

Skin infection by Mycobacterium farcinogenes-senegalense group in an immunocompetent patient: a case report

Background

Mycobacterium farcinogenes–senegalense group mostly cause bovine farcy, which rarely infect human beings. We reported one case of cutaneous Mycobacterium farcinogenes–senegalense group infection in an immunocompetent victim.

Case presentation

A 66-year-old Taiwanese woman with hypertension developed tender nodules on her left dorsal foot for 2 months. Tissue culture identified Mycobacterium farcinogenes–senegalense group. The lesion was treated successfully with clarithromycin and sulfamethoxazole/trimethoprim, followed by surgical excision.

Conclusions

Mycobacterium farcinogenes–senegalense group infection should be considered as a potential pathogen of skin infection in immunocompetent patients.
