Microscopic close view of high vaginal swab Gram stain smear, 100x. diagnosis of Bacterial vaginosis (BV).
Diffuse large B-cell lymphoma, or DLBCL, is a cancer that starts in white blood cells called lymphocytes.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
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.
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.

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.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change

Freshwater aquatic zooplankton and algae under microscope view
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.

Cheyletiella blakei Mite - Small Cat pest view under a microscope
newly hatched freshwater fish under a light microscope, isolated on white
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.
Super macro photo of Spider, butterfly caterpillar, Bee, Insects and Other animals in nature.
Pleomorphic liposarcoma. Site: Neck. Pleomorphic liposarcoma is a rare subtype of fat cell cancer in the body. It is a rare and very malignant type of tumor that usually arises from fat cells and deep soft tissues of the upper and lower extremities (shoulder, arms, legs, and thighs).
Frog in pond weed duck weed plant covering a still water sites creating good wildlife habitat Thailand Asia
Photomicrograph of midge fly, Chironomidae family, eggs hatching. Eggs are encased in a gelatinous material that attracts debris. Live specimen. Larva about 0.5 mm long. Wet mount, 10X objective, transmitted brightfield illumination.
Microscopic photo of a thin section of calcareous tufa of Holocene age.
