Symbolic illustration of infectious viruses under the microscope, for example influenza viruses, smallpox, measles or similar. Medical research and investigation of diseases and healthcare concept.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Epithelial Cells in urine sediment.
Fungal Ear Infection, Need to Use Antifungal Ear Drops to Treat Otomycosis.
The nematode Steinernema feltiae under the microscope, the species used as a biopesticide to infect fungus gnats in agriculture and gardening.
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.
Hyperproliferation, adenomatous polyps and pre-cancerous polyps are benign. Adenocarcinoma and colorectal cancer are malign.
Squash preparation of stained onion root tip cells showing late telophase and metaphase stages of mitosis. Bright field illumination on a Leica microscope, Image taken with the X100 objective lens.  Depth of focus is extremely shallow (less than one micron).  Optimum setting of the aperture for maximum resolution and good contrast. Chromatic aberation is inevitable in light microscopy, especially at this scale of magnification, but has been kept to a minimum in this image.
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
plant Stem of Nymphaea tetragona T.S. under light mircoscope with white background
Transmition Electron microscopy of an epithelial cell where mitochondria of several sizes can be seen with the characteristic double membrane and internal cristaes. Mitochondria are believed to be of bacteria origin. It has its own genome and RNA and protein which are similar to those of bacteria.

Mesenchymal dysplasia. Site: Placenta
ascaris megalocephala cross section under the microscope showing its cuticle, mesodermal cells, pseudoceloma and ovaries - optical microscope x100 magnification
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.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Computational tomography image of the abdominal and pelvic regions.
normal head  scan brain window
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Showing Light micrograph Type of Tissue Human under the microscope in Lab.
From left to right, axial, coronal and sagittal contrast-enhanced CT of the abdomen and pelvis of a young child demonstrating a large, aggressive abdominal tumor arising from the left kidney. This tumor and the attached kidney were removed and found to be a Wilms tumor. Named after Max Wilms, a German doctor who described the disease in 1899, Wilms tumor or nephroblastoma is the most common abdominal cancer and most common kidney cancer in children. It is often only diagnosed once it is large enough to feel or be seen pushing out of the abdomen. Fortunately, the vast majority of Wilms tumors are favorable histology and have a good chance of being cured with treatment. Treatment depends on the stage (size, location, spread) of tumor and begins with surgery to remove the tumor followed by chemotherapy, and often also radiation therapy.
Ciliary body. Two ciliary processes lined by a double epithelial layer, the non-pigmented inner epithelium and the pigmented epithelium.
Nephroblastoma with heterologous elements (teratoid Wilms' tumor). Wilms tumor (also called Wilms' tumor or nephroblastoma) is a type of childhood cancer that starts in the kidneys. It is the most common type of kidney cancer in children.
