Mycobacterium leprae infection (i.e., leprosy) is a disease that has been recognized—and often misunderstood—since ancient times. The emergence of HIV/AIDS and the development of newer culture methodologies and molecular diagnostic tools have brought about increased interest in the epidemiology, diagnosis, and treatment of human infections from nontuberculous mycobacteria (NTM). More than 140 species of NTM have been identified; approximately 50 of these may be pathogenic for humans, causing a broad spectrum of disease. This chapter covers both M. leprae and selected NTM organisms, including M. avium complex; M. kansasii; M. marinum; and rapidly growing mycobacteria such as M. chelonae, M. fortuitum, and M. abscessus. The section on leprosy encompasses subsections on diagnosis, clinical manifestations and classification, laboratory studies, treatment, and leprosy reactions. Treatments for nontuberculous mycobacteria infections are also covered. Figures include a natural history of leprosy, tuberculoid leprosy, lepromatous leprosy, and various forms of borderline leprosy, as well as type 1 and type 2 leprosy reaction. Tables include the Ridley-Jopling classification of leprosy, recommendations for treatment of leprosy, clinical characteristics and treatment of leprosy, major clinical syndromes associated with nontuberculous mycobacterial infections, diagnosing nontuberculous mycobacterial lung disease, a listing of slow and rapidly growing mycobacteria that are human pathogens, plus treatment regimens for selected nontuberculous mycobacterial infections in adults. This review contains 59 references.

Outbreaks of rapidly growing mycobacteria have been occasionally described. The article reports an outbreak of cutaneous abscesses due to Mycobacterium chelonae following mesotherapy in Lima, Peru. From December 2004 through January 2005, 35 subjects who had participated in mesotherapy training sessions presented with persistent cutaneous abscesses. Thirteen (37%) of these suspected cases consented to underwent clinical examination. Skin punch-biopsies were collected from suspicious lesions and substances injected during mesotherapy were analyzed. Suspected cases were mainly young women and lesions included subcutaneous nodules, abscesses and ulcers. Mycobacterium chelonae was isolated from four patients and from a procaine vial. In conclusion, it is important to consider mesotherapy as a potential source of rapidly growing mycobacteria infections.

Abstract Background The widespread use of molecular techniques has resulted in increasing numbers of newly characterized rapidly growing mycobacteria (RGM). Many RGM cause soft tissue and orthopedic hardware infection, particularly after trauma. RGM species identification remains challenging with few genetic differences between species. Methods We describe a case involving RGM. We report results of matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry (Bruker Biotyper), sequencing of rpoB, erm(39), and 16S rRNA genes, and antibiotic susceptibility testing (AST). We review previous reports describing similar RGM infections. Results A 58-year-old male sustained multiple fractures and right thigh compartment syndrome after a motorcycle accident. He underwent fasciotomy and multi-stage surgical fixations. 3 months later, he had wound dehiscence, purulence and multiple fluid collections of his right leg and knee requiring surgical drainage and removal of orthopedic hardware. After 4 days, acid-fast bacilli grew on routine bacterial culture media. MALDI-TOF identified the isolate as Mycobacterium mageritense. In contrast, sequencing of 16S rRNA (100% identity) and erm(39) (> 99% identity) identified the isolate as Mycobacterium houstonense; erm(39) only had 80% similarity with Mycobacterium fortuitum. Sequencing of rpoB showed a 19 bp difference with the M. houstonense type strain, and showed similarity to M. fortuitum (97.64%) than M. houstonense (97.45%). AST demonstrated resistance to clarithromycin only. After initial treatment with imipenem, ciprofloxacin, and doxycycline, definite therapy with ciprofloxacin and doxycycline was successful. In the literature, we found one case each of M. mageritense and M. houstonense infection after trauma. Conclusion This case highlights the importance of RGM other than M. fortuitum as a cause of soft tissue and orthopedic hardware infections, and illustrates the difficulty of identifying them to the species level. Sequencing of erm(39) and 16S rRNA gene identified the isolate as M. houstonense, but the larger difference (>2.5%) in rpoB sequence suggests a novel species. Further characterization is underway. Efforts to determine RGM species and antibiotic susceptibility give important insight into diagnosis and management. Disclosures All authors: No reported disclosures.
