The impact of co-infections with Theileria ovis and Anaplasma ovis on caprine health is very limited knowledge and is rarely documented in the literature. Türkiye is endemic for tick-borne diseases (TBDs), posing a risk of co-infections in goats. To evaluate the impact of single and co-infection with T. ovis and A. ovis on caprine health, four groups of goats were examined: healthy goats, goats infected with T. ovis, goats infected with A. ovis and goats co-infected with both species. Sera from blood samples was tested for oxidant/antioxidant markers [malondialdehyde (MDA), superoxide dismutase (SOD), catalase (KAT), glutathione peroxidase (GPx), glutathione S-transferase (GST)], cytokines [interleukins (IL)-6, IL-1, tumor necrosis factor-α (TNF-α)], DNA damage [8-hydroxy-2'-deoxyguanosine (8-OHdG)] and trace minerals [( copper (Cu), zinc (Zn), manganese (Mn), selenium ( Se)]. MDA, 8-OHdG, TNF-α, IL-1 and IL-6 levels, CAT and GST enzyme activities were found to be significantly increased in both Theileria ovis and Anaplasma ovis single- and co-infections (P
