objective(s) rapidly growing mycobacteria (rgm) are capable of producing diseases in humans. since mycobacteria vary in their susceptibility, precise identification is critical for adoption of correct drug therapy. the main aim of this study was molecular identification and evaluation of antimicrobial susceptibility pattern of iranian clinically isolated myocbacterium fortuitum. materials and m...
In the analysis by Parry et al. [Parry, J. M., Parry, E., Phrakonkham, P. and Corvi, R. (2010) Analysis of published data for top concentration considerations in mammalian cell genotoxicity testing. Mutagenesis, 25, 531-538], 24 rodent carcinogens that were negative in the Ames test were identified that were only positive in mammalian cell tests at concentrations between 1 and 10 mM. These carc...
Chemically synthesize carrier-bound peptides have been used as antigens in diagnostic test systems (ELISA) and for raising antipeptide-specific antisera. The method does not require prior cleavage of the peptides from the support used for the solid-phase synthesis. Using the same resin for both the synthesis and the subsequent applications it was possible to avoid expensive and time-consuming p...
OBJECTIVES Rates of macrolide resistance in group A streptococci (GAS) were reported to be low in the US in the 1990s. However, we documented an unexpectedly high rate of macrolide resistance among GAS in Pittsburgh, PA, in 2001 and 2002. In an effort to define the current prevalence of macrolide-resistant GAS in the US, a multicentre surveillance project was initiated. METHODS Between Octobe...
Polysaccharides from marine clams perform various biological activities, whereas information on structure is scarce. Here, a water-soluble polysaccharide MMPX-B2 was isolated from Meretrix meretrix Linnaeus. The proposed structure was deduced through characterization and its immunological activity was investigated. MMPX-B2 consisted of d-glucose and d-galctose residues at a molar ratio of 3.51:...
