Effects of some plant extracts on root-knot nematodes in vitro and in vivo conditions

İlker KEPENEKÇİ

One of the major pests of the vegetables, root knot nematodes (Meloidogyne spp.) (Tylenchina: Meloidogynidae) (RKNs) can cause economic losses by forming knots on the host plant roots. RKNs are more prevalent in the greenhouse vegetable growing areas of the coastal regions. In this study, the effects of plant extracts from five different plants; Capsicum frutescens, Hyoscyamus niger (Solanaceae), Melia azedarach (Meliaceae), Xanthium strumarium and Achillea wilhelmsii (Asteraceae) were evaluated against RKNs. In the first studies; the effects of plant extracts (0.5, 1.0, 1.5, 3.0, 6.0 and 12.0 ...More

The effect of ovulatory follicle size at the time of insemination on pregnancy rate in lactating dairy cows

Abdulkadir KESKİN

The aims of this study were to determine the factors that affect follicle size at the time of artificial insemination (AI) and to detect the relationship between ovulatory follicle size at the time of AI and pregnancy rate in dairy cows. A total of 1428 follicle size measurements were obtained from Holstein-Friesian (HF) and Swedish Red (SR) cows that were inseminated with the fixed-timed AI protocols used in this study. Follicle size was affected by breed (P - 0.0001), milk production (P - 0.01), parity (P - 0.05), and season (P = 0.04). Follicle size was greater (P = 0.0001) in the HF (15.55 ...More

The effects of varying levels of dietary starch on reproductivetraits in lactating dairy cows

Abdulkadir KESKİN

The aim of this study was to determine the effects of three different dietary starch levels on postpartum milk yield, blood metabolites, and reproductive traits in cows. A total of 23 primiparous Holstein-Friesian cows were fed three different diets including different starch levels on a dry matter basis from parturition until day 80. Cows were randomly assigned into the three groups according to the starch levels: low (LS, 16%, n = 7), medium (MS, 20%, n = 8), and high (HS, 24%, n = 8). Milk yields were recorded daily, and body condition score (BCS) was determined every week. Transrectal ultr ...More

Biological Control Potential of Turkish Entomopathogenic Nematodes Against Holotrichapion pullum (Gyllenhal) (Coleoptera, Apionidae)

İlker KEPENEKÇİ

Potential of three native Turkish isolates of entomopathogenic nematodes (EPNs) (Steinernema feltiae, S. carpocapsae and Heterorhabditis bacteriophora) was evaluated against Holotrichapion pullum (Gyllenhal) (Coleoptera, Apionidae) under laboratory conditions. Suspensions of EPNs were applied at three concentrations (500, 1000 and 2000 IJs ml-1) and at two temperatures (15 and 20°C). After one week, mortality rate of H. pullum adults was assessed. Mortality rate was higher in the nematode treatments than in the control. All nematodes showed more effect depending on temperature increase. At 20° ...More

Effects of Some Indigenous Plant Extracts on Mortality of the Root Lesion Nematode, Pratylenchus thornei Sher & Allen

The gen us of roo t lesio n nematod es (RLN), Pratylench us, feeds an d reprodu ces in the roo t co rtex of man y plant s pecies. RLN was rep roduced on carrot cu lture by using a pu re cu lture. In vitro tes ts were carried out to determine the effects of plant extracts from three ind igenous plants: h enbane, Hyoscyamus niger; b ead-tree, Melia a zedarah and commo n cocklebu r, Xanth ium strumarium on P. tho rn ei (the major wh eat root-les ion nematode). The nematodes were expos ed for 12, 24, 48, 72 an d 96 hrs in three concen tratio ns of plant extracts. Th e effect of plant extracts was ...More

Quantification of Mitral Regurgitation in Anatolian Shepherd Dogs with Asymptomatic Degenerative Mitral Valve Disease

Hasan GÜZELBEKTEŞ

Degenerative mitral valvular disease (DMVD) is the most frequent cardiac disease, causing mitral regurgitation (MR) in dogs. The purpose of this study was to compare the ratio of the regurgitant jet area (RJA) to the left atrial area (LAA) (RJA/LAA) with subtracting method to quantify regurgitant volume (RegV) and regurgitant fraction (RF) in asymptomatic Anatolian Shepherd Dogs (ASHs) with DMVD. Thirty-eight ASHs with DMVD were used as experimental group. The control group consisted of 35 healthy ASHs. In 38 ASHs with DMVD (20 B1 dogs and 18 B2 dogs), the severity of MR was assessed by RJA/L ...More

Cardiac biomarkers in premature calves with respiratory distress syndrome

Hasan GÜZELBEKTEŞ

The aim of this study was to determine the clinical relevance of cardiac biomarkers [troponin I and T, creatine kinase-MB fraction (CK-MB) and lactate dehydrogenase (LDH)] in premature calves with respiratory distress syndrome. Seventy premature calves were admitted to the clinic within 24 h after birth. Respiratory distress syndrome was diagnosed in premature calves by clinical examination and venous blood gas analysis. Ten healthy calves, aged 5 days, were used as control. Cardiac troponin I and T were analysed using ELISA and ELFA, respectively. Serum CK-MB and LDH were also analysed in an ...More

Canine coronavirus infection in dogs in Turkey: Virological and serological evidence

Orhan YAPICI

In the present study, virological and serological investigations were performed to determine the presence and prevalence of Canine corona virus (CCoV) infection in dog population in Turkey. Sera samples were analyzed for specific antibodies against CCoV by indirect enzyme linked immunosorbent assay (i-ELISA) while leukocyte samples were inoculated onto monolayers of Madin Darby Canine Kidney permanent cell culture. The cells were examined for viral antigen by direct immunofluorescence (IF) test after third passage. CCoV seropositivity was found in 46 (24.46%) of 188 dogs by indirect ELISA whil ...More

Murat KİBAR

The purpose of the study reported here was to determine echocardiographic findings in naturally heartworm-infected dogs, and evaluate these findings to use in the diagnosis of adult worms in the pulmonary artery. Sixteen male dogs (8.8%) of the 180 dogs in our study, weighing 7.5-42.0 kg, ranging in age from 1 to 8 years, were determined to be positive for Dirofilaria immitis according to the results of membrane filtration and antigen ELISA tests. Dogs identified with adult heartworms in their blood were evaluated by parasitological. The mean worm burden in infected dogs was 4730 ± 5479 (min: ...More

Ertan ORUC

This preliminary study was aimed at determining the occurrence of haemosporidian parasites in the blood of sparrowhawks. For this purpose, blood samples were prepared from 9 sparrowhawks. All birds had been collected from different areas of Northeast Turkey. Blood smears were stained with 5% Giemsa solution and examined under the light microscopy. A total of 7 individuals were infected (77.8%). Haemoproteus spp., Leucocytozoon spp. and Plasmodium spp. were detected in 5 (55.6%), 6 (66.7%) and 4 (44.4%) birds, respectively. There were no haemosporidian parasites in 2 birds (22.2%). We observed ...More

Congenital Glaucoma in Two Cats and Surgical Repair with Trabeculectomy

Murat KİBAR

This current work aims to assess the efficacy and tolerability of trabeculectomy procedure for the management of congenital glaucoma in two cats. Filtration surgery was performed using a limbus-based approach, and flap was raised smoothly to nearly limbus on sclera. Sclera-corneal trabecular block was removed both with surgical knife and microsurgery scissors. Successful result was defined as resolution of leakage with no need for additional surgery, together with maintaining intraocular pressure in the range of 5-21 mmHg with anti-glaucoma medications. In conclusion, trabeculectomy decreased ...More
