Accelerating invasion rate in a highly invaded estuary   总被引：4，自引：0，他引：4  

AN Cohen  JT Carlton 《Science (New York, N.Y.)》1998,279(5350):555-558

Biological invasions are a major global environmental and economic problem. Analysis of the San Francisco Bay and Delta ecosystem revealed a large number of exotic species that dominate many habitats in terms of number of species, number of individuals and biomass, and a high and accelerating rate of invasion. These factors suggest that this may be the most invaded estuary in the world. Possible causes include a large number and variety of transport vectors, a depauperate native biota, and extensive natural and anthropogenic disturbance.  相似文献   

Isolation of very virulent Marek''s disease viruses from vaccinated chickens in Australia     

JL McKIMM-BRESCHKIN  JT FARAGHER  J WITHELL  WM FORSYTH † 《Australian veterinary journal》1990,67(6):205-209

Very virulent Marek's disease viruses (vvMDV), defined as isolates against which the herpesvirus of turkey (HVT) vaccine provide poor protection, have been isolated from poultry flocks in both the United States and Europe. Twenty-one samples from vaccinated Australian flocks, experiencing problems with excessive Marek's disease (MD), were tested for the presence of transmissible MD viruses (MDV). Of the 16 samples which contained a transmissible agent, 14 were pathogenic in chickens, based on the development of MD lesions or depression of the bursa/body weight ratio. Of the pathogenic isolates which have been successfully typed 10 were serotype 1, and one was serotype 2 MDV. Pathogenicity of isolates varied. Several isolates caused tumours in 20-30% of both vaccinated and unvaccinated chickens. Two isolates, MPF6 and MPF23, caused tumours in more than 50% of chickens. When MPF6 and MPF23 were tested in vaccine trials bivalent vaccine gave no better protection against development of MD lesions than a monovalent vaccine. Isolate MPF23 was so pathogenic that lesions were produced in all chickens, regardless of the vaccine protocol used. Therefore vvMDV have been isolated in Australia, and unlike the vaccines tested overseas, bivalent Australian vaccines do not appear to provide greater protection against these vvMDV.  相似文献

Secondary lymphoedema in a dog     

N. G. CARMICHAEL†  A. D. J. WATSON†  T. L. W. ROTHWELL 《The Journal of small animal practice》1986,27(5):335-341

Oedema associated with obstruction of the lymphatic pathways is termed lymphoedema. A number of cases of primary lymphoedema attributed to congenital lymphatic abnormalities have been reported in dogs. Cases associated with secondary or acquired lymphatic drainage failure are rare. This paper reports a dog with generalized peripheral oedema in which a presumptive diagnosis of secondary lymphoedema was made and discusses the causes, investigation and treatment of lymphoedema.  相似文献   

Johne's disease in alpacas (Lama pacos) in Australia     

SE RIDGE  JT HARKIN† ‡  RT BADMAN†  AM MELLOR§  JWA LARSEN¶ 《Australian veterinary journal》1995,72(4):150-153

SUMMARY: Johne's disease was diagnosed in 10 alpacas ( Lama pacos ) in Australia between February 1993 and May 1994. Eight of the animals were between 12 and 24 months of age, one was a 6-year-old female, and one was a 4-year-old male. Five, including the 6-year-old and the 4-year-old alpacas, showed weight loss and diarrhoea before death or slaughter. The other cases showed no clinical signs of Johne's disease but 4 gave a positive result on faecal culture and one gave a positive result on testing with the caprine ACID assay and had acid-fast organisms in its faeces. At necropsy, all cases had grossly enlarged mesenteric lymph nodes. Johne's disease was diagnosed after histological examination of the lymph nodes with conventional culture and polymerase chain reaction testing of tissue samples. This report outlines the clinical, epidemiological, and pathological findings in these cases.  相似文献   

Glomerulopathy in dogs with congenital portosystemic shunts     

PLC TISDALL  TLW ROTHWELL †  GB HUNT ‡  R. MALIK 《Australian veterinary journal》1996,73(2):52-54

Kidney specimens from 12 dogs with congenital portosystemic shunts were examined histologically. Glomerulopathy of variable severity was present in the kidney sections of all 12. Marked irregular thickening of the glomerular capillary wall was the most prominent pathological change, the renal interstitium being largely unaffected. The severity of lesions was not correlated with the age of dogs at the time of necropsy. An immunoperoxidase technique failed to demonstrate significant IgA or IgG deposition in affected glomeruli. Proteinuria was generally mild or absent despite significant glomerular lesions, except in dogs with concurrent urinary tract infection.  相似文献
