(Walter de Gruyter Gmbh, 2018) Oguz, Bekir; Ozdal, Nalan; Deger, M. Serdar
Introduction: Toxocara canis and Toxocara cati are roundworms of dogs and cats. The purpose of this study was to investigate the infection caused by these ascarids in cats and dogs, using microscopic and molecular analysis methods. Material and Methods: Adult ascarids were gathered from the faeces of dogs and cats in Van province, in 2015-2016. Existing keys and PCR sequencing of the ITS-2 fragment were used to identify the morphological features of the parasite species. Results: It was observed that out of 20 adult ascarids, 17 and 3 were found to be Toxocara canis and Toxocara cati, respectively. The ITS-2 gene region was amplified by PCR to perform molecular analysis. Genotyping indicated that the dogs and cats were infected with T. canis and T. cati, respectively, and none had Toxascaris leonina. Conclusion: To the best of our knowledge, this is the first report on the molecular characteristics of adult ascaridoid nematodes from cats and dogs in Turkey. The molecular approaches established in this study enable molecular identification and genetic structure studies of the ascaridoids.

(Kafkas Univ, veteriner Fakultesi dergisi, 2010) Yetkin, Aysen; Deger, Serdar; Ozdal, Nalan
This study was carried out to investigate the prevalence of intestinal parasites among the students of Van Health High School and Faculty of Veterinary Medicine. Faeces samples were collected from 40 females and 70 males, a total of 110 students. Then, the samples were examined by using the methods of saturated salt water (Fulleborn's flotation technique), native-lugol and trichrome stain. Of the 110 students surveyed for intestinal parasites, 34 (30.9%) had one or more parasites. Infection was observed in 8 female (20%), and 26 male (37.1%) students. Twelve intestinal parasite species were detected in stool specimens. The most common intestinal parasites are Entamoeba coli (18.18%), Giardia intestinalis (14.54%), Entamoeba histolytica (13.63%) and Blastocystis hominis (11.81%) in the present study. In conclusion, the Students of University of Yuzuncu Yil, Faculty of Veterinary Medicine and Van Health High School had high intestinal parasitic infection. Thus, the results suggest that both students and community must be fully aware of this public health risk.

(Natl veterinary Research inst, 2009) Ozdal, Nalan; Tanritanir, Pinar; Goz, Yasar; Deger, Serdar; Kozat, Suleyman
This study was conducted to investigate the prevalence of parasitic protozoan agents in lambs with diarrhoea in the Van province (Eastern Turkey). Faecal samples from 132 diarrhoeic lambs aged from one day to two months old were collected at 12 different herds from January 2005 to May 2005. The faecal samples were examined by using, native-Lugol, Fulleborn's salty water technique, and a Modified Ziehl-Neelsen staining technique for Cryptosporidium. The parasitological examination revealed that 98 (74.24%) of the lambs were infected with one or more of parasitic protozoan agents. Eimeria, Giardia, and Cryptosporidium were detected in 80 (60.60%), 64 (48.48%), and 18 (13.63%) of the lambs, respectively. According to statistical analysis, Eimeria sp. oocysts were significantly higher (P < 0.01) in lambs aged between 3 1 and 60 d (76.81%, 53 of 69) than in those of 16-30 d of age (50%, 21 of 42) and 1-15 d of age (28.57%, 6 of 2 1). There were significant differences in Giardia prevalance when lambs of 1-15 d of age were compared with those 16-30 d of age (P < 0.05). Statistical analysis revealed that Cryptosporidium sp. oocysts were significantly higher (P < 0.01) in lambs aged between I and 15 d (66.66%, 14 of 21) than in those of 16-30 d of age (4.76%, 2 of 42) and 31-60 d of age (2.89%, 2 of 69). Moreover, Giardia sp. and Eimeria sp. showed significant co-occurrence (34.84%). The results obtained confirmed the fact that protozoan infections are widespread in diarrhoeic lambs in this geographical region.
Preliminary Studies on the Prevalence and Genotyping of Echinococcus Granulosus Infection in Stray Dogs in Van Province, Turkey
(Walter de Gruyter Gmbh, 2018) Oguz, Bekir; Ozdal, Nalan; Kilinc, Ozlem Orunc; Deger, M. Serdar
Introduction: Echinococcus granulosus is a zoonotic helminth of the Taeniidae family living in the small intestines of dogs. The hydatid cyst, which is the larval form of this parasite, is observed in sheep, goat, cattle, and many other organisms including humans. It causes a disease called cystic echinococcosis. Identification of strains of E. granulosus in dogs is critical in parasite control and eradication where possible. This study aims to determine the genotype of E. granulosus eggs and prevalence of this parasite in the faeces of dogs in the Van Province using the copro-PCR method. Material and Methods: This study was conducted between 2015 and 2016 on the faeces obtained from 100 stray dogs from different parts of the Van Province. The coprological examination was conducted using the formalin-ether concentration method. Results: Taeniidae eggs were found in 10 (10%) out of 100 faecal samples. E. granulosus was detected in 4 out of 10 of these (40%) infected samples. Sequence analysis of positive amplicons obtained from PCR showed that there were sheep strains (G1). Conclusion: Dogs in Van area are primarily infected with the livestock genotype of E. granulosus, which is thought to be a potential zoonotic threat to humans.

(Univ Zagreb vet Faculty, 2016) Ozdal, Nalan; Tanritanir, Pinar; Ilhan, Fatma; Deger, Serdar
This study was carried out to estimate the prevalence, larval burden and some risk factors of ovine oestrosis in 328 heads of randomly selected sheep slaughtered in one year at Van, eastern Turkey. Of the total heads, 127 (38.71 %) were infested with Oestrus ovis (Linnaeus, 1761, Diptera: Oestridae) larvae. The prevalence of O. ovis was 51.68 % in summer, 40.69 % in spring, 35.80 % in autumn, and 23.61 % in winter. The differences between seasons were statistically significant (P<0.05). Out of a total of 511 larvae collected, 17 % were L1, 29 % L2, and 54 % L3 larvae. All three larval instars were observed in all study months, apart from the fact that no first-stage larvae were seen in December and March. The overall larval intensity for the infested sheep was 4.02, with 3.42 in spring, 3.80 in summer, 4.03 in autumn and 5.82 in winter. The infestation rates were 41.26 % in female and 34.42 % in male sheep. The infestation rate in sheep less than 2-years-old was 23.33 %, in those 2 to 4 years-old 36.42 % and inj those older than 4 years old 48.43 %. Sheep with dark head color had a higher risk than sheep with white and spotted heads (P<0.05).

(Polish Soc veterinary Sciences Editorial office, 2018) Kilinc, Ozlem Orunc; Ozdal, Nalan; Bicek, Kamile; Deger, M. Serdar; Yuksek, Nazmi; Yilmaz, Ali Bilgin; Oguz, Bekir
This study was undertaken to investigate the effects of theileriosis on the cardiovascular system in cattle. Blood samples were collected from 50 cattle naturally infected with Theileria spp. (before and after treatment) as well as from 30 non-infected cattle. Hematological parameters and the serum concentrations of total cardiac troponin I (cTnI), aspartate aminotransferase (AST), creatine kinase (CK), and creatine kinase MB (CK-MB) were measured. Also coagulation parameters, plasma levels of activated partial thrombo plastin time (APTT), prothrombin time (PT) and D-dimer were measured. The presence of anemia and the levels of cTnI, CK-MB, CK and AST indicated statistically significant differences between infected and healthy cattle, but no statistically significant differences between the two groups were found in DD levels at the end of the study. Reduction in anemia and reduced levels of cTnI, CK-MB, CK, AST, APTT and PT were also found in post-treatment analyses. The results indicate that anemia, coagulation disorders and hypoxia in theileriosis in cattle can induce myocardial tissue damage.

(Medwell online, 2009) Tanritanir, Pinar; Ozdal, Nalan; Ragbetli, Cennet; Yoruk, Ibrahim; Ceylan, Ebubekir; Deger, Serdar
The aim of this study was to investigate the changes in the blood serum concentration of some biochemical parameters and lipid-soluble vitamin levels in the goats naturaly infested with lice and Trichostrongylidae sp. before and after treatment with moxidectin and effects of moxidectin treatment on these blood parameters. In this study, 20 hair goats naturaly infected with lice (Linognathus africanus) and Trichostrongylidae sp. and 10 healthy hair goats (control) were used as material. Blood samples were collected from infested and control groups. Serum samples were seperated and analysed for biochemical parameters with autoanalyser and some vitamins with high performance liquid chromatography. Animals in infested group were treated with ecto-endoparasitic drug (moxidectin) and in 8 and 15 days after treatment blood samples were again collected to determine some vitamins and biochemical parameters. As a results, concentrations of retinol, sodium, potassium, calcium and albumin were lower (p<0.05) and activity of alanine aminotransferase was higher (p<0.05) in infected goats than in the controls. There was no statistically significant difference in the concentration of vit D-3, tocopherol, total protein, glucose and activity of aspartate aminotransferase and alkaline phosphatase between infected and control group.
Status of Lipid Peroxidation, Antioxidants, and Oxidation Products of Nitric Oxide in Equine Babesiosis: Status of Antioxidant and Oxidant in Equine Babesiosis
(Elsevier Science inc, 2009) Deger, Serdar; Deger, Yeter; Bicek, Kamile; Ozdal, Nalan; Gul, Abdurrahman
Equine babesiosis is a tick-borne protozoal disease of horses caused by Theileria equi and Babesia caballi. The disease is endemic in most tropical and subtropical areas. The aim of this paper is to assess the antioxidant status, lipid peroxidation, and oxidation products of nitric oxide (NO) in horses and mules naturally infected with T equi and B. caballi. East and Southeast Anatolian horses and mules living in rural region of the Eastern border of Turkey were used as the material for this Study. These animals are used as pack animal (3-7 years of age). Infected animals were in acute or subacute infection period. In the current Study, malondialdehyde (MDA), oxidation products of NO (nitrate and nitrite), serum glutathione (GSH), vitamin E, and retinol levels were analyzed in 58 equids (horse and mule) infected with T equi and B. caballi as well as in 44 healthy equids. Compared with controls, the level of MDA and nitrate increased significantly (P < .01, P < .05, respectively), whereas GSH concentration and levels of vitamin E decreased significantly (P < .01). There was no significant change in the level of nitrite and retinol between two groups, The results of the current study suggest that in equids infected with T. equi and B. caballi, this alteration in the lipid peroxidation, oxidants, and antioxidants may be related to the host's defenses against parasitic infection and may play a central role in the pathologic conditions associated with babesiosis.
