Article Synopsis
- * The study tested different concentrations of ivermectin and EOCs on Rhipicephalus annulatus tick isolates, finding that while all EOCs were toxic to the ticks, no true synergistic effect with ivermectin was identified despite some combinations showing increased mortality.
- * The research suggests that combining ivermectin with certain EOCs, especially D-limonene and cinnamaldehyde, could enhance tick control methods, and further research is recommended to assess effectiveness in real-world scenarios.

Therefore, the present study was carried out to evaluate the protective effect of ultraviolet (UV)-irradiated sporulated oocysts of Eimeria species against coccidiosis in layer chickens. One hundred forty-four one-day-old layer chicks were randomly divided into 4 groups (n = 36), including non-immunized/non-challenged negative control group (NC group), non-immunized/challenged control group (NIC group), non-irradiated sporulated oocyst/challenged group (CA group), and UV-irradiated sporulated oocyst/challenged (UV group).
