Abstract: The biocompatibility and strong antimicrobial ability of silver and its derivatives have attracted the biomedical researchers for biomedical implants, water filtration and other bio-applications. Recently silver nanoparticles have also been engineered for biological applications, specifically as antimicrobial agents to overcome the antibiotic resistance in animals and humans. In this context, we have evaluated the antimicrobial activity of silver nanoparticles against the pathogenic poultry strains that affect the poultry production and performance. Silver nanoparticles were synthesized by oxidation reduction method using silver nitrate solution with sodium borohyride as the reducer. The particle size ranging from 168.57nm – 425.41nm was revealed from the SEM micrograph. The absorption wavelength of the UV visible spectroscopy at 392 nm ensured the presence of silver nanoparticles in the sample. The diffraction peak derived from 38° (111) indicates the presence of Face Centered Cubic pure crystalline silver. Antibiotic Disc Diffusion Test (ADDT), microtiter assay and ex-vivo studies revealed the effective antimicrobial activity, biofilm inhibition effect and also increased egg hatch rate than control group.
