centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification
superior view of heart showing opening of aorta, superior vena cava, pulmonary trunk with related valve
In vitro bacterial culture
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.

Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
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.
Euglena is a genus of single cell flagellate eukaryotes under microscopic view for study.

Freshwater aquatic zooplankton and algae under microscope view
Blue Square wooden box filled with blue book replicas
Moderate epithelial cells in urine specimen with yeast cells and bacteria real sample
Intricate bubble texture macro in bright colors for abstract background. Liquid bubbles lit from below with colors injected into the liquid as a design or art abstract.
Raspberry rust is a malignant disease caused by the phytoparasitic fungus Phragmidium rubi-idaei. This pathogen forms small ulcers on the leaves through which a huge mass of orange spores breaks through. Under a microscope, this pathogen does not look so sinister.
Concentric patterns and textures of Natural Agate slice for background.
