This study was conducted to evaluate oxidative stress using markers such as malondialdehyde (MDA), glu- tathione (GSH), total oxidant status (TOS), total antioxidant capacity (TAC) and oxidative stress index (OSI) in sheep naturally infected with Toxoplasma gondii (T. gondii). A total of 30 Morkaraman breed sheep were used in this study. Blood samples were obtained from 10 healthy control sheep and 20 sheep naturally infected with T. gondii. malondial- dehyde, GSH, TOS and TAC levels were determined in serum samples. The ratio of serum TOS to TAC levels was assessed as OSI. While the serum MDA level increased significantly (P

The purpose of this study was to investigate the serum lipid and protein profile as well as liver enzyme levels in neonatal calves with diarrhea. The study included 40 calves, 30 with diarrhea and 10 healthy (control). Calves with diarrhea were divided into three groups based on clinical findings: mild, moderate, and severe. Blood samples were taken from the vena jugularis after routine clinical examinations of the calves to determine the lipid profile, protein profile, liver enzyme levels, and glucose levels. Serum total cholesterol (TC) (P

The most common enteropathogens causing diarrhea in neonatal calves are Escherichia coli (E. coli) and rotavirus. Procalcitonin (PCT) is a parameter that has recently become widely used to determine whether infectious diseases are caused by bacteria. Iron is an essential nutrient for almost all bacterial species, and serum iron levels are used as an inflammatory biomarker. Therefore, in this study, we aimed to investigate the differential diagnosis value of serum iron and procalcitonin levels in E. coli and rotavirus diarrhea. The material of the study consisted of 30 calves 1-15 days old. Three groups were formed: E. coli (n=10), rotavirus (n=10) and control (n=10) groups. Calves in the E. coli group had the highest PCT (P=0.005) and CRP (P=0.003) levels, as well as the lowest Fe (P=0.000) levels. As a result, it was determined that serum Fe levels could be used as an inflammatory marker and PCT levels higher than 50 pg/mL could be used in the differential diagnosis of E. coli diarrhea in calves with 100% sensitivity and 100% specificity.
