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 usin...

The MB/BacT automated system is designed for the isolation of mycobacteria from clinical specimens. It utilizes a colorimetric sensor and reflected light to continuously monitor the CO2 concentration in the culture medium. We compared its performance to that of the BACTEC 12B media for the radiometric BACTEC 460 instrument and that of solid culture media. Respiratory specimens and urine samples...

Slowly growing, scotochromogenic bacteria of a novel Mycobacterium species were isolated from lymph node samples in two children and pulmonary samples in two elderly patients from different regions in the Netherlands as well as from a surface water sample in Zambia. Its 16S rRNA gene, 16S-23S internal transcribed spacer (ITS), hsp65 and rpoB gene sequences are unique in comparison with other my...

The identification of a widespread contaminant of plant cell cultures is reported. Mycobacterium scr~luhtceum Prissick and Masson appears as yellow colonies on the medium and plant tissues of many ornamentals being propagated in vitro. It is a Gram positive and acid fast bacterium and requires a specifically formulated medium for growth in pure culture. Many laboratories have alluded to this co...

INTRODUCTION The objective of the case report is to highlight the possibility of osteomyelitis caused by atypical mycobacteria. Such an infection may simulate tuberculous bone infection and yet fail to respond to standard anti-tuberculous drug therapy. CLINICAL PICTURE A 66-year-old man who suffered from diabetes mellitus presented with osteomyelitis of the right wrist, with extensive synovia...

In world leprosy nowadays, a favorable epidemiologic trend has been provided due to the best effort of the worldwide campaign with chemotherapy providing a bright but one-sided look at the future. However, the numbers of new patients are still higher than those under chemotherapy, leaving a concern over the remaining non-human source of infection. To overcome that plausibility, overall understa...
