Growth, Survival and Physiological Condition of Cultured Marron, Cherax tenuimanus （Smith, 1912） Fed Different Levels of Organic Selenium

引用

Journal of Agricultural Science and Technology(b) 2013年第2期3卷 125-135页

作者： rudy Agung Nugroho Ravi Fotedar Sustainable Aquatic Resources and biotechnology Faculty of Science and Engineering Curtin University Bentley WA 6102Australia

A 90-day feeding experiment was conducted to evaluate the effects of three levels of dietary supplementation of organic selenium （OS） on physiological and immunological responses of marron （Cherax tenuimanus）. Three levels viz. 0.1, 0.2 and 0.3 g kg^-1 of basal diet of Sel-Plex as a source of OS. were prepared and tested against the basal diet, which was used as a control. Each diet was fed to four replicated groups of marron, （initial mean weight of 39.43 ± 0.55 g）, at a rate of 3% body weight every second day. At the end of the feeding experiment, dietary inclusion of all Sel-Plex levels significantly improved specific growth rate （SGR） and survival of marron. Inclusion of Sel-Plex above 0.1 g kg^-1 resulted in significantly higher hepatopancreatic moisture level （HM） and wet hepatosomatic index （Hiw）, of marron than matron fed without Sel-Plex. Total Se level in the hepatopancreas was the highest （5.41 ± 0.28 μg g^-1） in the matron fed 0.2 g kg^-1 of Sel-Plex, whereas muscle accumulated significantly higher level of Se when man-on were fed 0.3 g kgl of dietary Sel-Plex. It is therefore suggested that the beneficial dietary supplementation levels of Sel-Plex in marron should range from 0.2 to 0.3 g kg^-1.

ISBN: (纸本)9781405184090

Over three editions the Handbook of Diabetes has built a reputation as an essential practical manual on the assessment and management of patients with diabetes. Previously written by Gareth Williams and John Pickup, the book has been completely revised by rudy bilous and Richard Donnelly to reflect recent changes in diabetes treatment and care. It contains information on the new IFCC units for measuring blood glucose and the latest drugs being used to combat diabetes, as well as alternative methods of insulin delivery. The book has been fully updated and redesigned to make it even more user-friendly, and contains case histories, practice points, and landmark clinical trials highlighted in color in each chapter where appropriate. It also features an entirely new set of 250 clinical photographs. The Handbook of Diabetes is the ideal practical handbook for all health professionals with an interest in diabetes care.

Evaluation of Real-Time PCR and Culturing for the Detection of Leptospires in Canine Samples

Advances in Microbiology 2012年第2期2卷 162-170页

Hartskeerl MSD Animal Health Department Microbiological Research and Development Boxmeer The Netherlands WHO/FAO/OIE and National Collaborating Centre for Reference and Research on Leptospirosis Department of Biomedical Research Royal Tropical Institute Amsterdam The Netherlands WHO/FAO/OIE and National Collaborating Centre for Reference and Research on Leptospirosis Department of Biomedical Research Royal Tropical Institute Amsterdam The Netherlands

Validated real-time PCRs detecting leptospires for veterinary purposes are not readily available. This paper describes the prospective evaluation of a SYbR Green-based real-time PCR on serum samples collected from experimentally infected dogs. Compared to culturing, the assay had a diagnostic sensitivity and specificity of 91.7% and 90.0%, respectively. Culturing for part is complementary to PCR and preferably both should be applied for diagnosis and vaccine challenge experiments. In a subsequent prospective study on the dynamics of experimental infections with serovars Canicola and Copenhageni and serovar complex bananal-Liangguang in young and adult dogs, the PCR was applied on serum samples in conjunction with culturing on blood, urine and kidney samples with the following results: 1) Leptospires persisted longer in the blood of young dogs than of adult ones;2) Numbers of viable leptospires in the blood are rapidly reduced but DNA remains occasionally detectable up to 7 days post infection;3) Appearance of viable leptospires in the urine follows a biphasic dynamics;4) EDTA hampers effective culturing from blood samples;5) Serovar Canicola persists longer in the blood of dogs than Copenhageni and bananal-Liangguang. Together with a markedly higher recovery rate from kidney samples (71% compared to respectively 33% and 0% in young dogs), this probably reflects the adaptation power of Canicola to its canine maintenance host. Appearance of leptospires in the urine samples indicates that experimental infections have been successful. PCR presents a valuable adjunct to the diagnosis of veterinary leptospirosis and the follow-up in vaccine protection experiments.

Effect of scots pine forest management on soil properties and carabid beetle occurrence under post-fire environmental conditions——a case study from Central Europe

background: Fires have a fundamental impact on phytocoenoses and, depending on the size of the fire, can have a positive or negative effect. The role of fires in the formation of the species composition of plants, restoration of stands and changes in soil properties is well studied. However, the long-term relationship between forest management methods, soil properties and epigeic entomofauna assemblages in post-fire areas is still not clear. The effects of Scots pine stand management methods on biochemical soil properties and ground beetle assemblages in the largest post-fire area in Central Europe after the second World were investigated. The study was conducted in the rudy Raciborskie Forest district in southern Poland. The soil properties and epigeic beetle community structure were analysed. The research covered areas with natural and artificial pine regeneration, which were subjected to various care ***: The tendency for higher accumulations of organic matter in the soil of stands that underwent natural regeneration was proven. The stimulating role of soil organic carbon on the activity of dehydrogenases in the soil of naturally renewed areas with silvicultural treatment(NRAT) was noted. Regardless of the manner of stand regeneration, the activity of β-glucosidase was higher in the areas in which breeding treatments were ***, managed forest stands presented a higher abundance of carabid beetles than stands without treatment practices. Thirteen epigeic beetle species from the families Geotrupidae, Carabidae, Curculionidae,Cerambycidae and Silphidae were captured, with beetles from the first two families being the most numerous. Rare epigeal carabid species in the fauna of Poland and Europe, such as Carabus glabratus(Paykull) and Carabus auronitens Fabr., found appropriate habitat conditions for survival in the post-fire areas. Compared with the other areas, in the NRAT area, there were better stand and soil properties and more fea
