Through our previous work, we have identified that novel oxazolidinone structures, the biaryloxazolidinone analogues containing a hydrazone moiety, act as promising antibacterial agents against gram-positive bacterial strains. Based on this active structure, in study, synthesized series of oxazolidinones and determined their anti-mycobacterial activities vitro Mycobacterium marinum-infected zeb...
We characterized the Mycobacterium marinum phagosome by using a variety of endocytic markers to follow the path of the bacteria through a mouse macrophage cell line. Using a laser confocal microscope, we found that the majority of viable M. marinum cells were in nonacidic vacuoles that did not colocalize with the vacuolar proton ATPase (V-ATPase), the calcium-independent mannose-6-phosphate rec...
Cutaneous infections caused by Mycobacterium marinum have been attributed to aquarium or fish exposure after a break in the skin barrier. In most instances, the upper limbs and fingers account for a majority of the infection sites. While previous cases of necrotizing soft tissue infections related to M. marinum have been documented, the importance of our presenting case is to illustrate the agg...
Infection of vertebrate hosts with pathogenic Mycobacteria, the agents of tuberculosis, produces granulomas, highly organized structures containing differentiated macrophages and lymphocytes, that sequester the pathogen. Adult zebrafish are naturally susceptible to tuberculosis caused by Mycobacterium marinum. Here, we exploit the optical transparency of zebrafish embryos to image the events of...
An immunocompetent 28-year-old male aquarium store employee presented with 1 month of intermittent epistaxis. A bleeding granulomatous lesion was identified over the right nasal septum ( Figure 1 ). Histopathology from the incisional biopsy revealed granulomatous inflammation with the presence of acid-fast bacilli ( Figure 2 ). Culture of the homogenized specimen on Middlebrook 7H11 agar after ...
Although it has been recommended that photochromogenicity of mycobacteria should be tested after incubation at 25 to 30 degrees C for 2 weeks (Wayne et al., Int. J. Syst. Bacteriol. 24:412-419, 1974), our results indicate that photochromogenicity should be determined at 37 degrees C in the dark and under continuous exposure to light for 2 weeks. The test at 37 degrees C gives more stable result...
