The Microscopic Examination of Milk

The microscope has been used to observe and count bacteria and somatic cells in raw milk since the early 1900’s. It has proven to be a valuable tool to the dairy industry. The milk smear procedure in use today is outlined in detail in the most recent edition of Standard Methods for the Examination of Dairy Products (i.e., SMEDP, 17 ed) and other references. For somatic cell counting, the Direct...

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...

The Comparison of Direct Microscopic Examination and Culture Results in Diagnosis of Cutaneous Leishmaniasis

Abstract Background and Objectives: one of the endemic foci for Cutaneous Leishmaniasis in Iran is Mashhad in which limited outbreak have recently been reported. The commonly used method for diagnosis is the clinical features confirmed by direct microspic examination and culture or biopsy. We compared these two tests to determine the level of their sensitivity, specificity and positive predicti...

Microscopic surface structure of liquid alkali metals

We report an x-ray scattering study of the microscopic structure of the surface of a liquid alkali metal. The bulk liquid structure factor of the eutectic K67Na33 alloy is characteristic of an ideal mixture, and so shares the properties of an elemental liquid alkali metal. Analysis of off-specular diffuse scattering and specular x-ray reflectivity shows that the surface roughness of the K-Na al...
