This study synthesized silver nanoparticles (Ag-NPs) using nitrate (AgNO3) as the ion source and sodium tripolyphosphate (STPP) reducing well capping agents. The Ag-NPs were confirmed initially specific λmax at 410 nm with UV-Vis spectrophotometry homogenously distributed, 100–300 size, round-shaped particles realized through atomic force microscopy (AFM) transmission electron (TEM) image analysis. various reaction condition-based studies revealed 0.01 M AgNO3 yields maximum particle after 4...

The inhibitory activities of grapefruit seed extract (GSE) on avian influenza virus (AIV), Newcastle disease (NDV), infectious bursal (IBDV), Salmonella Infantis (SI) and Escherichia coli (EC) were evaluated. Original GSE contained 0.24% benzalkonium chloride (BZC), however, 0.0025% BZC solution could not inactivate bacteria. activity diluted (×100, ×500 ×1,000 with redistilled water) against selected viruses bacteria was evaluated in this study. solutions incubated the pathogens over a...

An alkaline agent, namely food additive grade calcium hydroxide (FdCa (OH)2) in the powder form, was evaluated for its bactericidal efficacies chicken feces at pH 13. The point this evaluation neutralization of agent's time bacterial recovery, since otherwise results are substantially misleading. Without FdCa (OH)2 pH, spiked bacteria were killed within min recovery aqueous phase, but not solid form feces, hence, it has been demonstrated that when solid, took longer than liquid agent to...
