Anti-parasitic activity of zinc oxide nanoparticles against Eimeria tenella in broilers experimentally infected

In the study, zinc oxide nanoparticles (ZNOPs) at concentrations of 20, 40, and 60 mg/kg were tested for their antimicrobial action against oocysts Eimeria tenella. The E. tenella isolated from feces broilers received veterinary hospital in Diwaniyah Province initially diagnosed by compound optical microscopy. confirmed molecularly polymerase chain reaction targeting ITS1 gene with a molecular weight 409 bp. results first week showed that ZNOP 20 40 possess various activities tenella, while was most effective reducing excreted compared to positive control amprolium group, along appearance mild symptoms mortality rate 0.8%. second infection, rates generally decreased all treated groups. A comparison groups ZNOP-treated group had significantly lower number oocysts, birds this recovered during infection. These findings revealed prospect using ZNOPs challenging situations resistance anticoccidial agents.
