    Diagnostic importance of serum neopterin, procalcitonin and some acute phase proteins in cattle with lung hydatid cyst
    (Hellenic Veterinary Medical Society, 2025) Akyüz, E.; Aydın, U.; Merhan, O.; Karakurt, E.; Sezer, M.; Batı, Y.U.; Yıldız, U.; Nuhoğlu, H.; Erkılıç, E.E.; Ölmez, N.; Özaydın, İ.; Gökçe, G.; Erdoğan, H.M.
    In this study, it was aimed to determine the diagnostic importance of serum neopterin, procalcitonin, and some acute phase proteins in cattle with lung hydatid cysts. In the study, 30 cattle aged 2-8 years, Simmental or crossbred, constituted the patient group, and 10 healthy cattle in the same characteristics and age range constituted the control group. The cattle were included in the study after being diagnosed with lung hydatid cyst as a result of clinical, anamnesis, auscultation, radiographic examinations, laboratory and histopathological findings. Neopterin (21.60 nmol/L) and procalcitonin concentrations (146.77 ng/L) were significantly increased in the disease group compared to the control group (respectively: 7.22 nmol/L, 47.76 ng/L) (P<0.001). Haptoglobin (P<0.001) and ceruloplasmin (P=0.047) of the acute phase proteins werehigher in the patient group compared to the control group, while albumin was found to be lower (P=0.028). In conclusion, the evaluation of serum neopterin, procalcitonin, and some acute phase proteins in cattle with lung hydatid cysts was found to be important. Since hydatid disease is a zoonotic disease, it will be important to perform radiography scans and confirm the diagnosis with relevant biomarkers and take new protective measures. We think that the diagnosis will be strengthened by investigating neopterin and procalcitonin levels, especially in cattle with suspected lung cysts in radiographic findings.

    Redox balance in dairy cattle and their calves at birth and its relationship to colostral passive immunity
    (Hellenic Veterinary Medical Society, 2025) Gökçe, E.; Cihan, P.; Kuru, M.; Atakişi Onur; Erkılıç, Ekin Emre; Makav, M.; Erdoğan, H.M.
    Newborn calves are exposed to oxidative stress (OS) just after birth, and yet the role of colostrum in OS is not well detailed. The redox indicators, total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI)] along with immunoglobulin-G (IgG) concentrations were assessed in 21 healthy Swiss Brown mother-calf pairs. Furthermore, alterations in theseparameters and IgG concentrations were analysed in an additional 23 healthy calves during the first 45 days of life (day 0 = at birth, 1, 3, 7, 14, 28 and 45). TAS and TOS concentrations were determined calorimetrically and IgG level by commercial ELISA kit. A negative correlation was determined between colostral IgG and serum maternal TOS (r:-0.49, P<0.05) and colostral TAS (r:-0.54, P <0.05). Calves exhibited elevated levels of TOS (8.29±0.30), TAS (0.71 ± 0.02) and OSi (1.20 ± 0.08) at birth. However these levels decreased after the 24th hour (6.72 ±0.2, 0.65 ±0.03, and 1.05 ±0.05, respectively) and remained stable throught the study. In conclusion, our results suggest that newborn calves experience OS after birth and colostral antioxidants may highlights its potential role in mitigating OS in these calves. The results may be of help in improving antioxidant capacity, either by treating dams during pregnancy or by treating colostrum with substances with antioxidant properties.
