For the first time, high quality images of metal nanoclusters which were recorded in the constant height mode of a dynamic scanning force microscope (dynamic SFM) are shown. Surfaces of highly ordered pyrolytic graphite (HOPG) were used as a test substrate since metal nanoclusters with well defined and symmetric shapes can be created by epitaxial growth. We performed imaging of gold clusters wi...

Drug susceptibility profile of 53 Mycobacterium tuberculosis clinical isolates was studied by conventional solid and liquid culture methods. Forty three isolates were drug resistant to at least one drug and 10 were susceptible. The strain identification was performed by PCR amplification of mtp40 gene and strain subtyping was performed by Double Repetitive Element-PCR (DRE-PCR), IS6110 outward ...
