Microscopic image of cells of human oral mucosa with bacteria. 400 x magnification. - Mikroskopisches Bild von Zellen der menschlichen Mundschleimhaut mit Bakterien. Vergrösserung 400x.
Cropped image of scientist with microscope
Epithelial Cells in urine sediment.
Ranuncuus Root C.S. under light mircoscope with white background
Buccal mucosa cell is the lining of the cheeks and the back of the lips under the light microscope.
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.

Modern Abstract Background
Characteristics of anatomy and Histological sample Squamous epithelial cells under microscope, Human and isolated Cell.
Urothelial carcinoma, high grade. High-grade tumors have an aggressive appearance under a microscope and are assumed invasive in the kidney or ureter.
Paps smear: Inflammatory smear with HPV related changes. Cervical cancer. SCC

Moderate Red cell on center Mycobacterium Tuberculosis bacteria.
Embryonic stem cells under microscope.
Streptococcus pyogenes, pneumonia bacteria, epithelial cells and clue cells in sputum specimen analysed by light microscope.
Plasmodium falciparum is the most dangerous form of malaria. The parasites can be seen as numerous little red dots in.this thick blood smear scattered around the white blood cells. The red blood cells have been destroyed by tge Giemsa stain, and can therefore not be seen. Malaria is spread by mosquitoes. Millions of people are killed by malaria every year.

Science has never looked so beautiful
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Grunge Black Background
Blood smear of leukemia patient under microscope
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.
Bacteria cell and white blood cell Hemoculture.
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.
