ELECTRON MICROSCOPIC EXAMINATION OF ELASTIC FIBERS

The prevalence of coronavirus in fecal samples of neonatal calf diarrhea using electron microscopic examination

BACKGROUND:Neonatal calf diarrhea (NCD), also known ascalf scours, is caused by viruses, bacteria, and parasites.Coronavirus is one of the important causes of NCD syndrome.Electron microcopy has been used for demonstration of virusesin fecal samples of diarrheic calves since 1969. OBJECTIVES:The aim of this study was to determine the prevalence ofcoronavirus in fecal samples of neonatal calf di...

Electron Microscopic Examination of Subcellular Fractions

Large granule fractions, containing about 80% of the cytochrome oxidase of the tissue, were isolated from rat liver and used to prepare thin pellicles of packed particles which were submitted to quantitative electron microscopic examination. Various parameters describing the mitochondrial population were determined by measuring the size and number of mitochondrial profiles in sections, and the ...

Electron microscopic examination of Corynebacterium ovis.

Corynebacterium ovis (C. pseudotuberculosis) was examined by electron microscopy after being subjected to various methods of fixation. The organism exhibited a fine structure similar to other corynebacterial species in the appearance of its cell wall, plasma membrane, nuclear apparatus, cytoplasmic matrix, wealth and complexity of intracytoplasmic membrane systems, and polyphosphate granules. A...

Electron dense staining affinities of mouse oxytalan and elastic fibers.

The staining affinity of electron dense stains to mouse palatal elastic fibers and periodontal oxytalan fibers was assessed and compared. Tissues were stained routinely with uranyl acetate and lead citrate or with elastic tissue stains including: (1) silver tetraphenylporphine sulfonate, (2) tannic acid technique, and (3) a high iron diamine sequence. Staining results were assessed with an elec...
