Silver nanoparticles against pathogens

Streptococcus agalactiae (S. agalactiae) is a contagious pathogen of bovine mastitis. It has financial implications for the dairy cattle industry in certain areas of the world. Since antimicrobial resistance increases in dairy farms, natural antimicrobials from herbal origins and nanoparticles have been given more attention as an alternative therapy.

The unique property of the silver and gold nanoparticles having antibacterial activity drags the major attention towards the present nanotechnology. Synthesis of nanobodies is of great interest in the development of nanotechnological tool for biomedical applications. This study investigates a competent and sustainable route of AgNP and AuNP preparation using Camel milk, well adorned for their wide availability and healing property. The silver and gold nanoparticles were examined by UV-visible spectroscopy (Systonic 2203) that demonstrated a peak at 446 and 551nm respectively.

Green nanomaterials have gained much attention due to their potential use as therapeutic agents. The present study investigated the production of silver nanoparticles (AgNPs) from a silver-resistant Bacillus safensis TEN12 strain, which was isolated from metal contaminated soil and taxonomically identified through 16S rRNA gene sequencing. The formation of AgNPs in bacterial culture was confirmed by using UV–vis spectroscopy with an absorption peak at 426.18 nm.

In our present investigation, synthesis of nontoxic, eco friendly and cost effective silver nanoparticles, Phyllanthus acidus (P. acidus) was used as starting material. The influence of phyto-constituents present in aqueous extracts of Phyllanthus acidus was found to be effective in reduction of silver nitrate to free silver nanoparticles (PA-AgNPs).

Silver nano particles were synthesized using two potential isolates of Trichoderma, Psudomonas fluorescens and one isolate of pathogen Rhizoctonia solani cell free culture filtrates incubated at different days 0, 5, 10 and 15. The present investigation revealed that bionano preparations irrespective of the isolate source used, i.e., Trichoderma, P. fluorescens or R. solani were found better in decreasing the sheath blight incidence in vitro though variation existed in terms of quantum of disease reduction.
