“…Although rarely recovered in the United States, most isolates of M. malmoense have been found in northern Europe, Zaire, and Japan (124,132,151,458). Worldwide, the prevalence of M. malmoense is second only to the MAC in isolates from sputum samples and lymph nodes of children.…”

SUMMARY Within the past 10 years, treatment and diagnostic guidelines for nontuberculous mycobacteria have been recommended by the American Thoracic Society (ATS) and the Infectious Diseases Society of America (IDSA). Moreover, the Clinical and Laboratory Standards Institute (CLSI) has published and recently (in 2011) updated recommendations including suggested antimicrobial and susceptibility breakpoints. The CLSI has also recommended the broth microdilution method as the gold standard for laboratories performing antimicrobial susceptibility testing of nontuberculous mycobacteria. This article reviews the laboratory, diagnostic, and treatment guidelines together with established and probable drug resistance mechanisms of the nontuberculous mycobacteria.

Clinical and Taxonomic Status of Pathogenic Nonpigmented or Late-Pigmenting Rapidly Growing Mycobacteria

2002

The history, taxonomy, geographic distribution, clinical disease, and therapy of the pathogenic nonpigmented or late-pigmenting rapidly growing mycobacteria (RGM) are reviewed. Community-acquired disease and health care-associated disease are highlighted for each species. The latter grouping includes health care-associated outbreaks and pseudo-outbreaks as well as sporadic disease cases. Treatment recommendations for each species and type of disease are also described. Special emphasis is on the Mycobacterium fortuitum group, including M. fortuitum, M. peregrinum, and the unnamed third biovariant complex with its recent taxonomic changes and newly recognized species (including M. septicum, M. mageritense, and proposed species M. houstonense and M. bonickei). The clinical and taxonomic status of M. chelonae, M. abscessus, and M. mucogenicum is also detailed, along with that of the closely related new species, M. immunogenum. Additionally, newly recognized species, M. wolinskyi and M. goodii, as well as M. smegmatis sensu stricto, are included in a discussion of the M. smegmatis group. Laboratory diagnosis of RGM using phenotypic methods such as biochemical testing and high-performance liquid chromatography and molecular methods of diagnosis are also discussed. The latter includes PCR-restriction fragment length polymorphism analysis, hybridization, ribotyping, and sequence analysis. Susceptibility testing and antibiotic susceptibility patterns of the RGM are also annotated, along with the current recommendations from the National Committee for Clinical Laboratory Standards (NCCLS) for mycobacterial susceptibility testing

“…Other mycobacteria recovered included isolates with phenotypic profiles similar to species known to cause disease in humans: Group B: M. triplex; Group C: M. interjectum; Group D: M. scrofulaceum, and Group E: M. szulgai. (Falkinham 1996, Horsburgh 1996, Anonymous 1997, Zenone et al 1999, Hazra et al 2001. However, assignment of these environmental isolates to existing species is tenuous and requires additional genotypic studies.…”

Mycobacteriosis in striped bass Morone saxatilis of Chesapeake Bay, USA, was first diagnosed in 1997 based on the presence of granulomatous inflammation and acid-fast bacteria in skin and spleen. To confirm histopathology, bacteriological detection and identification of mycobacteria were begun using splenic tissue from fish with and without skin ulcerations. On the basis of initial studies using a variety of selective and nonselective media, decontamination, homogenization and incubation conditions, a simple and quantitative recovery method using aseptic necropsy of splenic tissue was developed. Optimal recovery was obtained by spread-plating homogenates on Middlebrook 7H10 agar with incubation for 3 mo at 23°C. Mycobacteria were recovered from 76% (n = 149/196) of fish examined. Mycobacterial densities exceeded 10 4 colony forming units · g tissue -1in 38% of samples (n = 63/168) that were examined using a quantitative approach. The most frequently recovered mycobacterium, present in 57% (n = 109/192) of characterized samples, was the recently named new species Mycobacterium shottsii. Polyinfections of M. shottsii and other mycobacteria were observed in 25% of samples (n = 47/192) with densities of M. shottsii usually 1 or more orders of magnitude higher than co-isolate(s). Other mycobacteria recovered included isolates that, based on phenotypic traits, resembled M. interjectum, M. marinum, M. scrofulaceum, M. szulgai and M. triplex. M. marinum, commonly associated with fish mycobacteriosis and human disease, was recovered infrequently (3%, n = 6/192). The presence of multiple mycobacterial types occurring at high densities suggests that a variety of mycobacteria could be causative agents of mycobacteriosis in striped bass from the Chesapeake Bay. Striped bass is the major recreational fish species in the Chesapeake Bay, and the significance of the current epizootic to human health and the potential adverse effects on fish stocks are not known.

An epizootic in Chesapeake Bay striped bass, characterized by skin lesions and granulomatous inflammation with associated acid-fast bacteria, was first described in 1997 (Baya 1998, Vogelbein et al. 1998. Bacterial diseases in striped bass exhibiting skin lesions and scale loss have been attributed to a variety of aetiologies, including Aeromonas, Edwardsiella, Flexibacter, Pseudomonas, and Vibrio spp. (Toranzo et al. 1983, Mitchell 1984, Sindermann 1988, Plumb 1991, Baya et al. 1997. However, in the current epizootic the presence of nonbranching acid-fast bacteria within granulomas implicated mycobacteria as the causative agent and represented the first time that fish mycobacteriosis had ...
