ABSTRACT
<b>Background and Objective:
</b> The proposed study involves the approach from the point of anti-viral activity of gold nanoparticles against the <i>Bluetongue virus</i>. Among viral diseases, Bluetongue is regarded as an economically scouring disease. Neither a vaccine nor an antiviral drug is available for the prevention or treatment of this disease. The antiviral activity of gold nanoparticles synthesized by a novel isolate of <i>Streptomyces tuirus</i> DBZ39 is the breakthrough of the study. <i>Streptomyces tuirus </i>DBZ39, a novel isolate obtained from alkaline soil was proved to be efficient actinomycetes, for the extracellular synthesis of gold nanoparticles. <b>Materials andMethods:
</b> An upstream bioprocess was optimized and developed for the synthesis of controlled size gold nanoparticles with solitary mono dispersal pattern in aurum chloride solution. The characterization and confirmation of gold nanoparticles were illustrated by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray Analysis (EDAX) and Fourier Transmission Infrared Radiation Analysis (FTIR). <b>Results:
</b> Biomass size of 3 g, substrate concentration of 1 mM, pH of 8.5 and temperature of 45°C were observed as optimum conditions for the synthesis of 15-24 nm size gold nanoparticles. The <i>Bluetongue virus</i> (BTV) which belongs to the genus Orbivirus in the family Reoviridae with 26 serotypes is an etiological agent of infectious and non-contagious Bluetongue disease of main sheep and several other domestic animals. <b>Conclusion:
</b> Gold nanoparticles for the 1st time, at a higher concentration of 164 dilutions revealed a very promising and novel antiviral property against the <i>Bluetongue virus</i>.Palavras-chave
