A total of 24 strains of the Mycobacterium fortuitum complex were tested for susceptibility to antimicrobial agents by the disk diffusion and agar dilution techniques. By comparing zones of inhibition obtained with the disk diffusion technique with results of minimal inhibitory concentration determinations, it was shown that disk diffusion results could predict in vitro susceptibility to select...

We consider diffusion in a disk, representing cell with circular interior compartment. Using bipolar coordinates, we perform exact calculations, not restricted by the size or location of intracellular find Green functions, hitting densities and mean times to move from compartment cellular surface vice versa. For molecules diffusivity $D$, are proportional $R^2/D$, where $R$ is radius cell. expl...

methicillin-resistant staphylococcus aureus (mrsa) is the main cause of hospital infection emerged over the last decades. rapid detection of mrsa is important for patient care and proper usage of infection control. detection of meca genes (encoding resistance to methicillin and other similar antibiotics) and nuc genes (encoding staphylococcal thermostable nuclease) by pcr method is now consider...

conclusions our findings showed a high occurrence of metallo-β-lactamase production among p. aeruginosa isolates in burn patient infections in our region. also, there are p. aeruginosa isolates carrying the bla-vim-1 and bla-vim-2 genes in isfahan province. background metallo-β-lactamase-production among gram-negative bacteria, including pseudomonas aeruginosa, has become a challenge for treatm...

Large scale magnetic field threading an accretion disk is a key ingredient in the jet formation model. The most attractive scenario for the origin of such a large scale field is the advection of the field by the gas in the accretion disk from the interstellar medium or a companion star. However, it is realized that outward diffusion of the accreted field is fast compared to the inward accretion...
