There has been an increase in outbreaks of neuropathogenic equine herpesvirus-1 (EHV-1) in the United States and Europe. However, the presence and frequency of neuropathogenic EHV-1 in Turkish horses are not known at present. This study aimed to investigate the frequency of EHV-1 and neuropathogenic strains of EHV-1 in the Marmara Region of Turkey. Samples were analyzed for the presence of EHV-1 and neuropathogenic EHV-1 by real-time PCR TaqMan probe assays. Overall detection rate of EHV-1 was 45.5% (51 of 112). The detection rates were 70.5% (24 of 34) in aborted fetuses, 53.3% (8 of 15) in neonatal deads, 66.6% (4 of 6) in foals, 40% (2 of 5) in dead mares, and 25% (13 of 52) in living mares. Overall detection rate of neuropathogenic EHV-1 was 7.8% (4 of 51), and the real-time PCR results were confirmed by sequencing. Neuropathogenic strains of EHV-1 were detected in the brain and lung of two mares with neurological disease but without a history of abortion, in the brain of a foal that died of respiratory disorder, and in the nasal swab from a mare with a history of abortion. On histopathology, nonpurulent meningoencephalitis, hemorrhages, and vasculitis were seen in the brain. In conclusion, results of this study indicated, for the first time, that the neuropathogenic EHV-1 is circulating in the Marmara Region of Turkey. The results of this study also show that the current risk for non-neuropathogenic strains is high, whereas risk for the neuropathogenic EHV-1-G2254 strain seems to be low. As outbreaks of EHV-1 continue in the Marmara region of Turkey, surveillance for neuropathogenic EHV-1 genotype should be maintained. 相似文献

The effects of vitamin E and vitamin E-selenium combination on seminal plasma arginase activity and nitric oxide level and some spermatological properties in rams were investigated in this study. For control group, animals were injected intramuscularly with physiological saline. For vitamin E group, rams were injected intramuscularly with 300 mg/ram vitamin E. For vitamin E + selenium group, animals were injected intramuscularly with 5 ml/ram vitamin E + selenium. The semen was collected by artificial vagina at 1st, 4th, 24th, 48th and 72nd hr after administration in each group. Significant decreases in seminal plasma arginase activity (at 1st, 24th and 48th hr), nitric oxide level (at 72nd hr) and abnormal sperm rate (at 1st, 24th and 72nd hr), and significant increases in semen volume (at 24th hr), semen mass activity (at 24th and 48th hr), sperm motility (at 24th, 48th and 72nd hr) and concentration (at 1st hr) were observed in vitamin E group compared with control group. Similarly, significant increase in semen volume (at 1st, 24th and 48th hr), mass activity, (at 48th hr), motility (at 48th and 72nd hr) and concentration (at 4th, 24th and 48th hr), and significant decrements in abnormal sperm rate (at 1st, 24th, 48th and 72nd hr), seminal plasma nitric oxide level (at 1st, 4th, 24th and 48th hr) and semen pH (at 24th and 48th hr) were detected in vitamin E + selenium group in comparison to the control group. As a result, it is suggested that vitamin E and/or vitamin E + selenium applications may improve reproductive performance. 相似文献

Total anthocyanins were extracted from eleven sweet cherry cultivars grown in Sakarya, Turkey. In vitro inhibition effects of extracted total anthocyanins on purified carbonic anhydrase I and II were investigated by using CO2 as a substrate. The results showed that all extracted total anthocyanins inhibited the hCA I and hCA II enzyme activities. Among all cultivars, ‘Merton Premier’ was found to be the most active one against both hCA I (IC50?=?0.83?µg/mL) and hCA II (IC50?=?1.16?µg/mL). Additionally, the DPPH activities of the extracts were investigated as antioxidant properties. The results exhibited that ‘Churchill’ and ‘Merton Premier’ have high antioxidant activity with 74.102% and 73.503% DPPH activity, respectively.

Current experiment was laid out in order to compare different kinds of organic manure and chemical fertilizer application in growing spinach under the open-field conditions in two successive seasons. Matador type spinach (Spinacea oleracea L.) was cultivated organically and conventionally and spinach growth, yield, vitamin C and nitrate concentrations were checked throughout two successive seasons (autumn and winter). Commercial chemical fertilizer was used as conventional application, and chicken manure (CM), farmyard manure (FM) and blood meal (BM) were used as organic manure applications as a single and as mixtures at different quantities by aiming to receive 150 kg N ha−1 for each, totally 19 applications. In general, autumn season gave the better results in terms of spinach growth, yield and resulted in lower nitrate concentration, whereas the vitamin C concentration was found to be higher in winter season. Reasonable applications to be recommended should be as follows with regard to the seasons; 3.5 ton ha−1 CM and 0.6 ton ha−1 BM + 0.85 ton ha−1 CM + 4.0 ton ha−1 FM for spinach growth; 3.5 ton ha−1 CM and 5.0 FM + 1.2 CM + 0.4 BM applications for spinach yield; 5.0 ton ha−1 FM + 2.5 ton ha−1 CM and 15.0 ton ha−1 FM for vitamin C and nitrate concentration in the autumn and the winter season, respectively. In conclusion, FM and CM can be used effectively in growing organic spinach especially in the autumn season and can be transferred successfully into an asset. 相似文献

This experiment aims to elaborate the influence of different organic manure applications on soil iron （Fe）, copper （Cu）, manganese （Mn） and zinc （Zn） contents in three successive seasons. Farmyard manure （FM）, chicken manure （CM） and blood meal （BM） and their mixtures and 1 control collectively 18 applications were tested under the open field conditions. All micro nutrients tended to increase with regard to the successive applications some of which were found to be statistically significant to a different extent. Considering the seasonal mean, an increase between the seasons in Fe, Cu and Mn contents were found to be statistically insignificant, whereas the Zn content was found to be statistically significant. CM gave rise to an augmentation in Cu, the Mn and Zn contents, BM also showed a tendency to increase in Fe contents of soils, but we recommend using BM only in small quantities due to the unfavorable features of the material. Summing up, 2.5 ton ha^-1 CM ＋ 0.3 ton ha^-1 BM and 2.5 ton ha^-1 CM ＋ 4.0 ton ha^-1 FM applications gave the better results. 相似文献

It is crucial to know how management factors influence soil test phosphorus (P) since non-point P sources for surface waters are becoming recognized as a problem throughout the USA. Phosphorus fertilizer and crop residue can impact the cycling of P in soils. An eight-year crop residue removal and P fertilization (0, 7.3, 14.7 and 29.4 kg P/ha) as triple superphosphate (TSP) experiment were conducted to determine the effect of P applications on soil P fractions. Significant differences in Bray-l extractable P were observed after only one year of P applications. Extractable P at the highest P rate was significantly higher than all the other rates. For each 5.6 kg P/ha added or removed, Bray-l P changed by 1 mg/kg. Fertilizer P applications did not significantly change the organic P (Po) levels, microbial P (Pm) or soil pH, whereas residue treatments had effects on them except for soil pH. Residue-retained plots had significantly higher Pm in the last two years of study, and Po in the 8th year, compared with residue-removed plots. 相似文献

The aim of this study was to investigate Bovine Spongiform Encephalopathy (BSE) in Turkish cattle in the Marmara region which borders the European Union (EU). For this, cattle brought to abattoirs in Istanbul were analysed. The high risk group were selected and therefore 384 cattle above 2 years old were included in the study. They were primarily examined for the presence of any clinical signs of nervous system and also other clinical disorders. The whole brains were taken and analysed for the presence of vacuolar degeneration and prion protein by PLATELIA BSE test kit. Only 5 cattle were found to be nervous and showed aggressive behaviour. There were no cattle showing incoordination or other neurological disorders. Cysts were observed in 3 brains. Histopathologically, no vacuolar degeneration indicative of BSE was found in any cattle examined. However, in 8 brains, few vacuoles were observed in neurons in sections taken from the brain, cerebellum, medulla oblongata and medulla spinalis. Slight mononuclear cell infiltration in 9 brain, intensed mononuclear cell infiltration in 1 brain, haemorrhages in 5 brains and gliosis in 11 brains were also found. No infective prion was detected by ELISA in samples taken from 384 cattle brain. 相似文献
