    Assessment of prevalence of Fasciola hepatica and associated biochemical alterations in the cattle of Siirt province, Turkey
    (Agricultural Research Communication Centre, 2019) Celik, Ozgur Yasar; Celik, Burcak Aslan; Irak, Kivanc; Akgul, Gulsah
    The aim of this study is to determine the prevalence of Fasciola hepatica in the cattle raised in the Siirt province of Turkey and to obtain epidemiologic data about the disease in order to reveal its relationship with certain biochemical parameters. The material of the study consists of a total of 380 cattle. The blood sample was obtained from the jugular vein of the animals. Meanwhile, approximately 50-100 gr of feces were also collected from the animal's rectum for a fecal examination. The zinc sulfate flotation method was used to inspect the fecal samples. 338 (89%) of samples were found to be seronegative, while the remaining 42 (11%) were seropositive. GGT, ALP, ALT, AST, TP and Albumin parameters analyzed on the serum samples. GGT levels of the seropositive animals were found to be statistically higher compared to the control group. As a result, the ELISA method was confirmed to be more accurate in the diagnosis of fasciolosis, and the increased GGT activity in the serum was determined as a significant indicator of the diagnosis.

    Comparison of adiponectin levels and some metabolic parameters in dairy cows with subclinical and clinical ketosis
    (Polish Soc Veterinary Sciences Editorial Office, 2018) Akgul, Gulsah; Mecitoglu, Zafer; Kucuksen, Duygu Udum; Senturk, Sezgin
    The aim of the presented study was to evaluate the relationship between adiponectin and the non-esterified fatty acids (NEFA), beta-hydroxybutyric acid (BHBA), glucose, albumin, gamma-glutamyl transferase (GGT), calcium, phosphorus and blood urea nitrogen (BUN) levels in healthy cows and cows suffering clinical or subclinical ketosis in the early postpartum period. A total of 45 Holstein-Friesian dairy cows, consisting of 15 with clinical ketosis, 15 with subclinical ketosis and 15 healthy controls, was used in the study. The selection of animals was based on blood BHBA levels and urine ketone strip results on day 7 after parturition. Blood adiponectin, NEFA, glucose, albumin, GGT, calcium, phosphorus and BUN were also measured on day 7 postpartum. Adiponectin levels were significantly lower in both clinical ketosis and subclinical ketosis groups compared to the control group. NEFA levels were higher and glucose and calcium levels were lower in both ketosis groups when compared to the control animals. On the other hand, blood albumin, GGT, phosphorus and BUN levels did not differ among study groups. Based on the results of the study, it can be stated that adiponectin may play a role in the pathogenesis of ketosis. This role could be a lower milk yield and better energy balance in early postpartum dairy cows with high adiponectin levels due to increased whole body tissue insulin sensitivity.

    Investigation of Seroprevalence of Toxoplasma gondii in cattle in Siirt province in Turkey
    (Agricultural Research Communication Centre, 2018) Celik, Ozgur Yasar; Ipek, Duygu Neval Sayin; Celik, Burcak Aslan; Irak, Kivanc; Akgul, Gulsah
    Toxoplasmosis is an important zoonotic disease, which is caused by Toxoplasma gondii and is quite common in the world, found in all mammals including humans, poultry, and reptiles. It has been reported that; adult cattle do not have toxoplasmosis clinically, and it is possible they pass the parasite through the placenta to the fetus, and that some infected animals give birth to aborted or infected calves. This study was conducted to determine T. gondii seroprevalence in cattle of Siirt region in Turkey and seropositivity was determined in blood samples of 300 cattle by using ELISA. Results showed that 53 (18%) of the samples were seropositive, while 247 (82%) of the samples were seronegative. In addition, there was a significant difference between their average age groups.
