A quadrant streak of the bacterium Staphylococcus aureus cultured or inoculated on Baird-Parker agar with egg tellurite .
Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body
Backgrounds of Bacteria and Mold under the microscope in Lab.
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.
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.

Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
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.
Host cells with spores (mold) are inside wood under the microscope for education.
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.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
Viral Infection Monkeypox Virus - 3d rendered image. Abstract biomedical illustration. \nAntibody, Antigen, Vaccine technology concept.
Epithelial Cells in urine sediment.
Curly marble stone with fashion veins.
Microscope photo of a sambucus stem with parenchyma cells.
The pale lactose nonfermenting bacterie (blue arrow) are Salminella typhi.  Salmonella in general does not ferment lactose (colorless colonies),  Salmonella typhi,unlike other salmonallae, produce little hydrogen sulfide (H2S) gas.  The resulting bacterial colonies will appear colorless with colorless or very discrete black centers.
Lymphocyte. Immune cell. Antibody-producing cell. B-lymphocyte or T-lymphocyte in blood with red blood cells.Medical science background.
Fatty liver disease (steatosis) is a common condition caused by having too much fat build up in your liver. A healthy liver contains a small amount of fat. It becomes a problem when fat reaches 5% to 10% of your liver's weight.
