Threadworm (Enterobius vermicularis) eggs containing worm larvae, computer illustration. Threadworms are nematode worms that parasitize the large intestine and caecum of many animals. In humans they cause the common infection enterobiasis. Nematodes are unsegmented worms that may be parasitic or free-living depending upon the species.

An MRI PET scan of the abdomen in axial view provides a detailed cross-sectional image, helping to detect abnormalities with high precision.
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.

Mitosis of Human Cells
PAPS Smear study of a young women under microscopy showing Atrophic changes in uterus which is unusual at young age.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Diffuse large B-cell lymphoma, or DLBCL, is a cancer that starts in white blood cells called lymphocytes.
Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
corn stem micrograph with dye
Photomicrograph of Stomach Adenocarcinoma. Gastric Adenocarcinoma.
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.
Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
