Einbau der Zuchtarbeit in den KB-Betrieb: I. Allgemeiner Teil     

Von K. Eibl  R. Hahn 《Reproduction in domestic animals》1968,3(2):88-96

Inhalt: 1. Der systematische Einbau der Zuchtarbeit in den Besamungsbetrieb ermöglichte sich erst mit der Urnstellung des gesamten KB-Betriebes auf TG-N₂-Samen .
2. Die allgemeine Umstellung auf TG-N₂-Samen brachte bezüglich der Befruchtungsergebnisse keine Nachteile, sondern durch Nutzung der besonderen Möglichkeiten des Gefriersamens vielmehr eine deutliche allgemeine Konsolidierung und Stabilisierung der Befruchtungslage .  相似文献

Phylogenetic characterisation of bluetongue viruses from naturally-infected insects, cattle and sheep in Australia   总被引：1，自引：0，他引：1

SUMMARY The polymerase chain reaction was used to detect the presence of blue-tongue virus (BTV) in a number of clinical and insect samples collected in the Northern Territory of Australia. Sequence analyses of the amplified BTV genes differentiated endemic Australian and exotic viruses. Two potential exotic BTV were detected as a result of PCR analyses of blood from sentinel animals and of the insect vector, Culicoides wadai. The detection of BTV in C wadai was the first direct demonstration of the presence of BTV in this potential vector. This new technology can significantly reduce the time taken for a diagnosis from a clinical sample and increase the amount of useful information obtained on a BTV isolate by using rapid sequencing techniques. Sequence data were used to differentiate between BTV20 isolated in 1975 and two isolates of the same serotype, isolated in 1992, and indicated that the latter were probably a recent incursion into Australia from Indonesia due to their greater VP3 sequence homology to the BTV9 (Java) than to Australian BTV isolates.  相似文献   

Immune complexes in Aleutian disease: demonstration of antibody on isolated virus   总被引：1，自引：0，他引：1  

E C Hahn 《Veterinary immunology and immunopathology》1984,5(4):313-321

The specific binding of Staphylococcal protein A for mammalian immunoglobulin G was used to demonstrate IgG associated with Aleutian disease virus (ADV) when isolated from infected mink tissues. Protein A specifically bound to mink serum Ig with no reaction with other serum or tissue proteins. Protein A labeled with 131Iodine reacted with crude virus preparations but not with virus that had been purified by freon extraction to the point where it became reactive with antibody by counterimmunoelectrophoresis. Binding to purified ADV was restored when the purified virus was first reacted with antibody. Results of urea treatment indicated this as an alternative method for isolation of ADV free from antibody.  相似文献   

Single agent gemcitabine chemotherapy in dogs with spontaneously occurring lymphoma     

Turner AI  Hahn KA  Rusk A  Gamblin RM  Cosgrove SB  Griffice K  Khanna C 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2006,20(6):1384-1388

BACKGROUND: Gemcitabine has been shown to be effective as a single agent in a variety of tumors including nonHodgkin's lymphoma. Its use in veterinary medicine has been limited and to date this drug has not been used as a first-line therapy in dogs with lymphoma. HYPOTHESIS: Gemcitabine as a single agent may be efficacious in dogs presented for the first time with lymphoma. ANIMALS: Twenty-four dogs with spontaneously occurring lymphoma. METHODS: All dogs were clinically staged and given gemcitabine at 400 mg/m(2) over a 30-minute intravenous infusion weekly for 3 weeks and then given 1 week off treatment before starting a second cycle. RESULTS: A single dose of gemcitabine lowered both neutrophil count (decrease in mean neutrophil count from 10,640 cells/ microL to 3,140 cells/microL) and platelet count (decrease in mean platelet count from 201,290 cells/microL to 139,190 cells/microL) 7 days after administration. Consequently gemcitabine dosage was reduced at the second treatment in 8 of 21 dogs or a dose delay of 1-7 days and a reduction of dosage was used in 7 of 21 dogs. Seven dogs completed the assigned 4-week cycle. Two of these dogs had progressive disease and 5 had stable disease. No objective responses were seen in dogs treated with a second cycle of gemcitabine. CONCLUSIONS AND CLINICAL IMPORTANCE: Gemcitabine administration as a single agent resulted in hematologic toxicity and did not reduce lymphoma burden. If gemcitabine is to be used in veterinary medicine, additional prospective pharmacologic studies should be done to determine the appropriate dosage, regimen, and schedule of use before it can be recommended for use in the treatment of dogs with lymphoma as a single agent.  相似文献   

Location of Acidovorax citrulli in infested watermelon seeds is influenced by the pathway of bacterial invasion     

Dutta B  Avci U  Hahn MG  Walcott RR 《Phytopathology》2012,102(5):461-468

Watermelon seeds can become infested by Acidovorax citrulli, the causal agent of bacterial fruit blotch (BFB) of cucurbits via penetration of the ovary pericarp or by invasion of the pistil. This study investigated the effect of these invasion pathways on A. citrulli localization in seeds. Seed samples (n = 20 or 50 seeds/lot) from pistil- and pericarp-inoculated lots were dissected into testa, perisperm-endosperm (PE) layer, and embryo tissues and tested for A. citrulli by species-specific polymerase chain reaction (PCR) and by plating on semiselective media. Less than 8% of the testa samples were A. citrulli-positive regardless of the method of seed inoculation. Additionally, the difference in percentages of contaminated testae between the two seed lot types was not significant (P = 0.64). The percentage of A. citrulli-positive PE layer samples as determined by real-time PCR assay was significantly greater for seeds from pistil-inoculated lots (97%) than for seeds from pericarp-inoculated lots (80.3%). The mean percentage of A. citrulli-positive embryo samples was significantly greater for seeds from pistil-inoculated lots (94%) than for seeds from pericarp-inoculated lots (≈8.8%) (P = 0.0001). Removal of PE layers and testae resulted in a significant reduction in BFB seed-to-seedling transmission percentage for seeds from pericarp-inoculated lots (14.8%) relative to those from pistil-inoculated lots (72%). Additionally, using immunofluorescence microscopy, A. citrulli cells were observed in the PE layers and the cotyledons of pistil-inoculated seeds but only in the PE layers of pericarp-inoculated seeds. These results suggest that pericarp invasion results in superficial contamination of the testae and PE layers while pistil invasion results in the deposition of A. citrulli in seed embryos.  相似文献
