Determination of Parasite Fauna of Chicken in the Van Region
(2009) Orunç, O.; Biçek, K.
The aim of this study was to determine the parasite fauna of the chicken in Van Province in 2002 and 2003. The material of the present study included endoparasites and ectoparasites determined by rutine parasitological examinations. Direct, flotation and sedimentation techniques for endoparasites were used. The total of endoparasites and ectoparasites were determined as 85% and 76% respectively. The ratios of endoparasites obtained from the chicken were coccidial oocystis 65%, Echinostoma spp. 2%, Davania proglottina 8%, Raillietina spp. 10%, Trichostrongylus tenuis 4%, Dispharynx nasuta 1%, Ascaridia galli 13%, Heterakis gallinarum 15%, Capillaria spp. 30% whereas ratios of ectoparasites were Goniocotes hologaster 32%, Lipeurus heteragraphus 6%, Eomenacanthus stramineus 42%, Menacanthus cornutus 11%, Menopon gallinae 22%.
Determination of the Status of Lipid Peroxidation and Antioxidants in Cattle Infected With Dictyocaulus Viviparus
(2008) Deǧer, S.; Deǧer, Y.; Ertekin, A.; Gül, A.; Biçek, K.; Ozdal, N.
Endoparasites cause significant economic losses and health problems in domestic animals. In this study, lipid peroxidation and the antioxidant status were investigated in the lung tissue taken from twenty cattle infected with Dictyocaulus viviparus and ten healthy cattle. Malondialdehyde superoxide dismutase, catalase, glutathione, vitamin C and beta-carotene were measured. In comparison to the control group, the concentration of MDA was high (p < 0.001), but the activities of Cu-Zn-SOD and CAT, and the concentration of GSH, vitamin C and beta-carotene were low (Cu-Zn-SOD, CAT, GSH, vitamin C, p < 0.001 and beta-carotene p < 0.05) in the parasite infected group. These results suggested that endoparasitic infection is among the major causes of oxidative stress. Lipid peroxidation was observed and the activities and concentrations of antioxidants systems were decreased in the lungs of cattle infected with Dictyocaulus viviparus.
Prevalence of Coenurus Cerebralis in Van, Turkey and the Significance of the Enolase (Nse) Enzyme as a Supporting Parameter in the Diagnosis of Coenurosis
(Ataturk Universitesi, 2019) Biçek, K.; Karakuş, A.; Deǧer, M.S.
This study investigated the prevalence of Coenurus cerebralis in sheep in the province of Van, Turkey, its seasonal incidence and serum Enolase enzym levels with ELISA method. 64.7% of the examined animals (156 out of 241 sheep) were found to be positive in terms of C cerebralis. The rate of infection was found to be 35.7% in male and 29% in female sheep. While coenurosis was seen by 46.9% in sheep in the age range of 0-1 year, it was determined to be seen by 17.8% in sheep over the age of 2 years. Coenurus cysts, 32.1% were in the right hemisphere of the brain, 46.8% were in the left hemisphere, 12.2% were in both hemispheres, 5.1% were in the cerebellum and 3.8% were in the occipital region. It was a statistically significant finding that the incidence of the cysts in both hemispheres was found only in males (female: 0 cysts, male: 19 cysts) (P<0.05). Coenurus cysts was seen the most frequently in November (10.4%), while it was seen the least frequently in May (2.1%). In the sheep with coenurosis Enolase levels in the blood serum of the total of 80 (40 females, 40 males) animals that were found in the range of 5.44-84.96μg/l. Enolase enzym levels were found to be high in all animals with clinical symptoms. In patients with no symptoms, the results were found to be within the Cut-off limits. The results were statistically significant (P<0.05). Moreover, there was no significant difference between the males and the females. As a result, it was concluded that the enolase enzyme can be used as an auxiliary parameter in the diagnosis of sheep with clinical signs of coenurosis. © 2019 Ataturk Universitesi.

Seroprevalence of Fasciola Hepatica in Sheep in the Province of Van and Some Districts
(Ataturk Universitesi, 2018) Denizhan, V.; Biçek, K.
This study was carried out on 352 sheep 110 of which is below the age of 2, 171 is between 2-6 and 71 is above the age of 6 to determine the prevalence of fasciolosis caused by Fasciola hepatica in sheep in the centre of Van and its districs Özalp, Saray, Gevaş and Gürpinar between January and December 2009. All feces and blood samples were examined in the point of the eggs of parasite in feces and specific antibodies, respectively by Benedek sedimentation and antibody ELISA techniques. The origin of sheep, date of sample collection, age and sex of the sheep were recorded. In the research areas, the coprological prevalence and seroprevalence of fasciolasis in sheep were determined as 15.63 % and 49.43%, respectively. In the infected sheep, Fasciola hepatica were found by benedek sendimentation. The highest prevalence seroprevalence of Fasciolosis was observed among the sheep above age of 6 (83.9 %) and followed by 2-6 age group (46.19%) and <2 age group of sheep (36.32%). In the point of statistics, the difference between the age groups was significant (According to Chi-Square testing P<0.001). The seroprevalence of fasciolasis was %50.35 among females and %45.71 among males which was not accepted as a remarkable difference (P>0.001). As a result Fasciola hepatica was commonly detected in sheep in Van province. Epidemiology and control of this parasitic infections in the region for further studies are needed. © Ataturk Universitesi. All rights reserved.
