Objective To estimate the specificity of an absorbed enzyme-linked immuno-sorbent assay kitd for Johne's disease (JD) when used in mature cattle populations resident in northern Australia. Design Blood samples were collected from beef cattle in north

Objective To determine the sensitivity and specificity of an absorbed ELISA and an AGID test for the detection of clinical and subclinical paratuberculosis in sheep. Design By testing a panel of sera from 1257 Australian Merino and crossbred sheep gr

Cadmium chloride was administered to Sprague-Dawley rats in drinking water at 100 ppm for 39 weeks. The mean cadmium concentration in kidneys from 5 rats at the end of this period was 102 +/- 17 micrograms g-1 wet weight (mean +/- SE) compared with 0

The morphological changes in renal proximal tubules of Sprague Dawley rats given acute or chronic exposure to cadmium were analysed. Cadmium chloride was administered either by five subcutaneous injections of cadmium at 2 mg kg-1 body weight or in dr

The technique for X-ray microanalysis of frozen-hydrated bulk specimens was used to determine the intracellular and luminal fluid electrolyte concentrations in the proximal tubules of kidneys from chickens infected with infectious bronchitis virus. E

Summary Water and electrolyte balance was examined throughout the course of an experimental infection with T strain infectious bronchitis virus in colostomised chickens. Significant losses of water and negative sodium and potassium balances were obse

The secretory tubule epithelium of the avian nasal salt gland has been thought to secrete a hyperosmotic fluid containing high concentrations of Naα and Cl−. It is shown by X-ray micro-analysis that the average composition of the luminal fluid of

SUMMARY In coated frozen-hydrated gelatin gels the backscattered electron yield does not increase during electron irradiation as it does in uncoated samples. Neither is the backscattered electron yield greater from coated frozen-hydrated gels than th

summary It is shown by X-ray point analyses and line scans that the concentrations of sodium and potassium, as crown ether complexes, in epoxy resin may not be of uniform distribution. The concentrations may be substantially higher in a thin layer at

SUMMARY X-rays from light elements (Z=6–12) experience marked absorption in biological or organic matrices. Consequently surface tilt has a strong effect on X-ray intensity. Using epoxy resin models with well-defined surface tilt variations the eff
