recently, biosynthesis of nanoparticles has received attention due to an increasing need of developing rapid, simple and ecofriendly protocol. pathogenicity of some of the organisms and lengthy reaction are the drawbacks involved with biosynthesis. we describe a simple protocol for rapid synthesis of silver nanoparticles through biological route using a marine-derived fungus aspergillus niger. ...

dna sequencing is the most conclusive method for emm (m protein gene) typing of streptococcus pyogenes. this method is not a feasible approach in developing countries where streptococcal infection is widespread among adults and children. alternatively the pcr-rflp has the potential for rapid screening of different types of s. pyogenes. to document the emm type distribution of s. pyogenes in a g...

Developing suitable frameworks and paradigms (theoretical and practical) is a challenge for all disciplines in the face of rapid technological changes. Technological advances are fundamentally changing discourse in many well-established areas of research; from advances in understanding the brain, questioning the informed wisdom of sectors of the brain, through to impacts of social networks on s...

background and objectives: rapid clinical manifestation/progression of the meningococcal meningitis and lacunae in conventional bacteriological test often encourages indiscriminate use of antibiotics much before the etiology is established. this study was planned to evaluate ctra pcr for rapid molecular detection. in addition, multiplex pcr and sequencing was done for serogroup prediction to pr...
