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.

Trematode parasite under a microscope
Paramecium caudatum is a genus of unicellular ciliated protozoan and Bacterium under the microscope.

Lepocinclis acus or euglena acus, a single cell flagellate eukaryote under the microscope
Cheyletiella blakei Mite - Small Cat pest view under a microscope
Epithelial Cells in urine sediment.
Euglena is a genus of single cell flagellate eukaryotes under microscopic view for study.
Urothelial carcinoma, high grade.  High-grade tumors have an aggressive appearance under a microscope and are assumed invasive in the kidney or ureter.
Freshwater aquatic zooplankton and algae under microscope view
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.
Microscopic image of the operculum of a shrimp with possible disease. Research. Study. Laboratory. Aquaculture. Findings of disease in shrimp.
Cheyletiella blakei Mite - Small Cat pest view under a microscope
Microscopic examination of Stool showing Blastocystis hominis parasite.
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.
Paramecium caudatum is a genus of unicellular ciliated protozoan and Bacterium under the microscope.

Volvox sp. algae under microscopic view, dark background
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
