“…It has been reported that the long-lasting effects of immunopotentiation of BCG are due to persistence of the bacteria in the lymphoid tissues [29]. These results support the hypothesis in our previous study [13], i.e., that BCG induces transient infection and has the potential to induce a long-lasting immune response in fish.…”

“…Vaccination with extracellular mycobacterial products (Chen et al 1996) and DNA vaccines (Pasnik and Smith 2005) have demonstrated the efficacy of these techniques in stimulating specific antibody production and eliciting an immune response. Similarly, vaccination with attenuated mycobacteria shows some promise for protective immunity in zebrafish (Cui et al 2010) and other aquaculture species (Kato et al 2011). …”

Mycobacteriosis, a chronic bacterial infection, has been associated with severe losses in some zebrafish facilities and low-level mortalities and unknown impacts in others. The occurrence of at least six different described species (Mycobacterium abscessus, M. chelonae, M. fortuitum, M. haemophilum, M. marinum, M. peregrinum) from zebrafish complicates diagnosis and control because each species is unique. As a generalization, mycobacteria are often considered opportunists, but M. haemophilum and M. marinum appear to be more virulent. Background genetics of zebrafish and environmental conditions influence the susceptibility of fish and progression of disease, emphasizing the importance of regular monitoring and good husbandry practices. A combined approach to diagnostics is ultimately the most informative, with histology as a first-level screen, polymerase chain reaction for rapid detection and species identification, and culture for strain differentiation. Occurrence of identical strains of Mycobacterium in both fish and biofilms in zebrafish systems suggests transmission can occur when fish feed on infected tissues or tank detritus containing mycobacteria. Within a facility, good husbandry practices and sentinel programs are essential for minimizing the impacts of mycobacteria. In addition, quarantine and screening of animals coming into a facility is important for eliminating the introduction of the more severe pathogens. Elimination of mycobacteria from an aquatic system is likely not feasible because these species readily establish biofilms on surfaces even in extremely low nutrient conditions. Risks associated with each commonly encountered species need to be identified and informed management plans developed. Basic research on the growth characteristics, disinfection, and pathogenesis of zebrafish mycobacteria is critical moving forward.

“…They are pleomorphic, Gram-positive, acid fast, nonmotile, nonsporulating, and rod shaped (1). The genus Mycobacterium currently contains 148 recognized species, including M. marinum , M. pseudoshottsii , and an unidentified Mycobacterium sp., which are the mostly commonly identified bacterial fish pathogens (2, 3). Some are also zoonotic, causing cellulitis, skin tuberculosis, and foreign body reactions in humans (4).…”
