This common bacterial infection is spread through contaminated food or water and causes diarrheaa and possibly sepsis.  One of the most prevalent bacterial causes of food poisoning is salmonella and outbreaks of Salmonella Enteritidis linked to eggs have been reported.
Squash preparation of plant cells stained to reveal nuclei and chromosomes, Bright field illumination, light microscopy. This image was taken with the X40 objective lens. Depth of focus is extremely low at this magnification. Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced. The aperture in this image was optimised for contrast and resolution. Chromatic aberration is inevitable in light microscopy, but has been kept to a minimum in this image.
False colour electron microscope micrograph showing the Golgi apparatus (blue), mitochondria (green), very dilated RER cisterns (pale yellow) and secretory granules (dark red) in a gonadotropic cell.\
Adipose tissue under the microscope view show contains large lipid droplet.
In vitro bacterial culture
Haematococcus pluvialis is a freshwater species of Chlorophyta from the family Haematococcaceae. Haematococcus pluvialis is the richest source of natural astaxanthin.

View in microscopic of dog vaginal smear cells.Squamous epithelium cells.Superficial and intermediate epithelial cells.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
