Isolation and characterisation of cervine herpesvirus-1 from red deer semen     

Tisdall DJ  Rowe SM 《New Zealand veterinary journal》2001,49(3):111-114

AIM: This communication describes the isolation of herpesvirus during routine export examination of semen collected from red deer stags in New Zealand. METHODS: Virus isolation was carried out using bovine embryonic lung (BEL) cells and viruses were characterised by direct immunofluorescense, restriction-fragment-length polymorphism analysis (RFLP), polymerase chain reaction (PCR) analysis and nucleotide sequencing. RESULTS: Herpesvirus was isolated from red deer semen on 2 different occasions from different animals. In both cases the virus was identified as cervine herpesvirus-1 (CvHV-1), based on RFLP, PCR and sequence analysis. Nucleotide sequence analysis of the glycoprotein-D gene showed 99.7% homology to the Banffshire strain of CvHV-1 and 89.5%, 89.2%, 85.3% and 79.6% homology to bovine herpesvirus 1.2 (BoHV-1.2), bovine herpesvirus 1.1 (BoHV-1.1), cervine herpesvirus-2 (CvHV-2) and caprine herpesvirus-1 (CpHV-1), respectively. CONCLUSION: This is the first time that CvHV-1 has been isolated in New Zealand. Its inclusion in serological surveys will allow the prevalence of CvHV-1 in the red deer population to be assessed in this country. The clinical significance of CvHV1 infection in New Zealand red deer herds has yet to be determined.  相似文献

Tillage management changes size-distribution of aggregates and macro-structure of soils used for irrigated row-crops     

H.H. Adem  J.M. Tisdall  P. Willoughby 《Soil & Tillage Research》1984,4(6):561-576

The Tatura system for the preparation of seed-beds for irrigated annual row-crops is described, where the soil is tilled when wet and friable and so requires few passes with implements to become suitable for crops, and where seeds are sown into wet soil. In soil prepared by the Tatura system, the percentage of aggregates < 0.5 mm diameter (as measured by dry-sieving) in the seed-bed was about half that found in commercially prepared seed-beds which were tilled up to 50 times when dry. With the Tatura system, the wetter the soil (up to 22% water content) when tilled, or the more passes (up to 4) of the implement at a water content of 22%, the less dust (< 0.5 mm diameter) and/or fewer clods (> 20 mm diameter) were formed.

The macro-structure of the surface layer of soil tilled at different water contents by the Tatura system was also quantified statistically by the method of wax-impregnation. The macro-structures were compared at the 10 mm, 20 mm, 40 mm, 60 mm and 80 mm depths in beds of soil prepared for irrigated annual row-crops by a system which has been described previously. Within each treatment (21.7%; 19.0%; 11.6% water content at 0–100 mm depth at tillage), the linear porosity and mean pore-size each tended to decrease with depth to 40 mm, with no further change or slight decrease to 80 mm depth. In all treatments, the mean aggregate-size tended to increase with depth from 10 mm depth to 80 mm depth. The sizes of pores and aggregates varied across each bed and possibly depended on the position of tines within the bed at each pass at tillage. Water content at tillage led to small differences in structure of the beds of soil. Soil tilled at a water content slightly above the Casagrande Plastic Limit generally had slightly larger pores and aggregates than soil tilled at lower water contents.  相似文献   

Outcomes of cellophane banding for congenital portosystemic shunts in 106 dogs and 5 cats     

Hunt GB  Kummeling A  Tisdall PL  Marchevsky AM  Liptak JM  Youmans KR  Goldsmid SE  Beck JA 《Veterinary surgery : VS》2004,33(1):25-31

OBJECTIVE : To report outcomes after cellophane banding of single congenital portosystemic shunts in dogs and cats. STUDY DESIGN : Retrospective study of sequential cases. ANIMALS : One hundred and six dogs and five cats. METHODS : Medical records were reviewed for breed, sex, age at surgery, shunt anatomy, results of pre- and postoperative biochemical analysis, development of postligation neurologic dysfunction, portal hypertension or other serious complications, and the owners' perception of their animal's response to surgery. RESULTS : Ninety-five dogs and all 5 cats had extrahepatic shunts. Eleven dogs had intrahepatic shunts. Six dogs (5.5%) died as a result of surgery from portal hypertension (2 dogs), postligation neurologic dysfunction (2), splenic hemorrhage (1) and suspected narcotic overdose (1). Serious complications were more common in dogs with intrahepatic shunts than those with extrahepatic shunts (P=.002). Postligation neurologic dysfunction necessitated treatment in 10 dogs and 1 cat; 8 dogs and the cat survived. Clinical signs attributed to portosystemic shunting resolved or were substantially attenuated in all survivors. Postoperative serum bile acid concentrations or results of ammonia tolerance testing were available for 88 animals; 74 (84%) were normal and 14 (16%) were abnormal. Multiple acquired shunts were documented in two animals. CONCLUSIONS : Cellophane banding is a safe and effective alternative to other methods of attenuation. CLINICAL RELEVANCE : Slow occlusion of portosystemic shunts using a variety of methods is being evaluated world wide. Cellophane banding is a relatively simple procedure with comparable safety and efficacy to previously reported techniques.  相似文献   

Nocardia infections in cats: a retrospective multi-institutional study of 17 cases

OBJECTIVE: To record 17 cases of nocardiosis in cats from eastern Australia and to compare this series with cases previously reported. DESIGN: Retrospective/prospective study. RESULTS: Nocardia spp infections were diagnosed in 17 cats over 14 years from the three eastern states of Australia. There were no isolates from dogs during this period, but one isolate from a koala and two from dairy cows. The majority of cats presented with spreading lesions of the subcutis and skin associated with draining sinus tract(s). Early cutaneous lesions consisted of circumscribed abscesses. Infections spread at a variable rate, generally by extension to adjacent tissues. Lesions were generally located in regions subjected to cat bite or scratch injuries, including limbs, body wall, inguinal panniculus and nasal bridge. In some other cases, lesions were situated on distal extremities. The clinical course was variable, from chronic, indolent, initially localised infections to acute fulminating disease. Of the 17 cats, 14 were domestic crossbreds and three were purebreds. There was a preponderance of male cats (12 castrated, 1 entire young adult, 1 entire kitten). Nine of 17 cats were 10 years or older. Interestingly, the majority of infections were attributable to N nova. Immediate and/or predisposing causes could be identified in all cases, and included: renal transplantation [one cat]; chronic corticosteroid administration [three cats]; catabolic state following chylothorax surgery [one cat]; fight injuries [seven cats]; FIV infections [three of seven cats tested]. Of the 17 cats, three were apparently cured. Four were thought to be cured, but infection recurred after several months. Three cats responded partially but were euthanased, while another was improving when it died of unrelated complications. Two died despite treatment and two were euthanased without an attempt at therapy. For two cats there were either insufficient records or the patient was lost to follow up. CONCLUSION: Nocardiosis is a rare, serious disease. Currently it is more common in cats than dogs. Nocardial panniculitis may be clinically indistinguishable from the syndrome caused by rapidly growing mycobacteria. Although the prognosis is guarded, patients with localised infections caused by N nova often respond to appropriate therapy. If definitive treatment is delayed because of misdiagnosis, the disease tends to become chronic, extensive and refractory. Insufficient duration of therapy leads to disease recurrence.  相似文献   

Diaphragmatic hernia in a cat mimicking a pulmonary mass     

White JD  Tisdall PL  Norris JM  Malik R 《Journal of Feline Medicine and Surgery》2003,5(3):197-201

A seven-year-old castrated British shorthair cross cat was presented for coughing of five-weeks duration. Thoracic radiographs and an unguided bronchoalveolar lavage showed changes consistent with inflammatory airway disease. In addition, a soft tissue density was evident in the thoracic films between the heart and the diaphragm. Exploratory thoracotomy demonstrated a diaphragmatic hernia, probably congenital in origin, with incarceration of a portion of the hepatic parenchyma. The herniated portion of liver was resected surgically and the defect in the diaphragm closed. The cat was given a 10-day course of doxycycline post-operatively and the cough did not recur subsequently. In retrospect, the hernia was potentially an incidental problem, the cat's coughing being attributable to inflammatory airway disease.  相似文献
