Peritonitis,abscessation and haemorrhage: Complications of transcutaneous caecal decompression     

L. Unger  N. Fouché  D. Schnider  S. Witte 《Equine Veterinary Education》2014,26(8):430-435

Transcutaneous needle decompression of the caecum through the right flank is a valuable, routine procedure performed to resolve cases of large intestinal tympany. Nevertheless, it can be the cause of potentially life‐threatening complications as highlighted by the 3 cases presented in this case report. Abscess formation, septic peritonitis and haemorrhage following needle decompression are described.  相似文献   

Plant regeneration from cotyledons and embryonic axes in apple: Sites of reaction and effect of pre-culture in the light   总被引：1，自引：0，他引：1  

J. Keulemans  K. de Witte 《Euphytica》1994,77(1-2):135-139

Summary Mature embryos of the cultivar Gloster were isolated from seeds of fruits stored at 1 °C. Embryonic axes and wounded cotyledons were pre-cultured in the light for 0 to 6 days on embryo growth medium (experiment 1) or for 0 to 24 hours on shoot induction medium (experiment 2). After a subsequent dark period of 3 weeks for induction of organogenesis, explants were cultured in the light on shoot elongation medium. Up to 95% of the embryos formed shoots, while the mean shoot number per embryo reached 6.4. Regeneration frequency was influenced by the type of explant: embryonic axes reacted better (75%) than the tops of the cotyledons (29%) or wounds on the cotyledons (9%). The mean total shoot number per embryo comprised means of 2.3 for embryonic axes, 1.8 for tops of cotyledons and 2.3 for wounds on cotyledons (experiment 1). Wounds on the proximal part of the cotyledon reacted much better than those on other parts. Shoot differentiation was highest when cotyledons were cultured with the adaxial side on the medium, suggesting that there exist gradations within the cotyledon for regeneration capacity (experiment 2). The number of shoots per reactive site was not normally distributed, while a high frequency of 6 or more shoots per reactive site was found (experiment 1). A pre-culture of more than 24 hours in the light seemed to have negative effect, but there was no clear evidence whether this was a light and/or a medium effect.  相似文献   

Induction of humoral antibodies by a BHV-1 intradermal test]     

R Jungblut  W Hopp  F Wessel-Ellermann  K H Witte 《DTW. Deutsche tier?rztliche Wochenschrift》1991,98(7):286-288

An intradermal test for the diagnosis of BHV 1 (Intrakutantest Behringwerke AG) was applied to 53 nonvaccinated BHV 1-seronegative cattle aged 7 months to 8 years. Serologic blood testing performed subsequently using ELISA (Enzygnost-IBR/IPV, Behringwerke AG) and SNT revealed seroconversion in 24 of 45 animals without previous maternal antibodies. A second application of the intradermal test after these BHV 1-antibodies had declined, lead to a 'booster-effect' while a control group remained negative. Six of nine animals not affected by the first intradermal application of BHV 1-antigen, developed BHV 1-antibodies following the second intradermal test. Eight animals possessing maternal antibodies showed no serological response to the intradermal test at all. Present results strongly suggest an induction of humoral BHV 1-antibodies by the intradermal application of inactivated BHV 1. Consequently, the indirect control of BHV 1 infections, especially in cattle breeding farms, should be done exclusively by serological examination.  相似文献   

Wild fallow deer (Dama dama) as definitive hosts of Fasciola hepatica (liver fluke) in alpine New South Wales     

DJ Jenkins  A Baker  M Porter  S Shamsi  DP Barton 《Australian veterinary journal》2020,98(11):546-549

To determine the extent to which wild deer are contributing in the transmission of Fasciola hepatica (liver fluke) livers from deer shot by hunters, farmers undertaking population control on their farms and vertebrate pest controllers were collected and frozen. The livers were later thawed, sliced and examined for the presence of adult flukes or evidence of past infection. Livers from 19 deer were examined (18 fallow [Dama dama] and one sambar [Rusa unicolor]). Seventeen of the fallow deer were animals collected on farms near Jindabyne, New South Wales. The remaining fallow deer was collected in the Australian Capital Territory and one sambar deer was collected in north-eastern Victoria. Nine of the 17 deer (53%) from the Jindabyne area were either infected with Fasciola hepatica (liver fluke) or had thickened bile ducts indicating past infection. Infection levels in the infected animals varied widely from 3 liver fluke to over 50 per liver. No sign of infection was present in the deer from the Australian Capital Territory or Victoria. Fallow deer are wide-spread in the Jindabyne area and their population is increasing. It is likely their contribution to the maintenance and distribution of F. hepatica to livestock in the Jindabyne area, and in other livestock rearing areas of south-eastern Australia, is important and increasing.  相似文献   

Pore Fluid Constraints on the Temperature and Oxygen Isotopic Composition of the Glacial Ocean     

DP Schrag  G Hampt  DW Murray 《Science (New York, N.Y.)》1996,272(5270):1930-1932

Pore fluids from the upper 60 meters of sediment 3000 meters below the surface of the tropical Atlantic indicate that the oxygen isotopic composition (delta18O) of seawater at this site during the last glacial maximum was 0.8 ± 0.1 per mil higher than it is today. Combined with the delta18O change in benthic foraminifera from this region, the elevated ratio indicates that the temperature of deep water in the tropical Atlantic Ocean was 4°C colder during the last glacial maximum. Extrapolation from this site to a global average suggests that the ice volume contribution to the change in delta18O of foraminifera is 1.0 per mil, which partially reconciles the foraminiferal oxygen isotope record of tropical sea surface temperatures with estimates from Barbados corals and terrestrial climate proxies.  相似文献   

Lost zooplanktivorous cichlid from Lake Victoria reappears with a new trade   总被引：1，自引：1，他引：1  

E. F. B. Katunzi  J. Zoutendijk  T. Goldschmidt  J. H. Wanink  F. Witte 《Ecology of Freshwater Fish》2003,12(4):237-240

Abstract –  The zooplanktivorous cichlid Haplochromis pyrrhocephalus , which was one of the most common haplochromine species in the Mwanza Gulf of Lake Victoria, had almost completely disappeared after the Nile perch upsurge in the 1980s. In the second half of the 1990s, this species suddenly reappeared in the strongly changed ecosystem. Gut content investigation revealed a change in diet. Currently, H. pyrrhocephalus eats large prey more frequently than in the past. These large prey comprise fish, shrimps and molluscs. The latter two were never encountered in specimens from the past. Particularly feeding on molluscs was unexpected, as it had been suggested that, because of anatomical constraints, molluscivory and zooplanktivory are incompatible in cichlid fish. Our observations provide a new example of the extreme versatility in feeding behaviour in haplochromine cichlids.  相似文献
