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.
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.

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

Bacteria Aggregatibacter, 3D illustration. Aggregatibacter aphrophilus and A. actinomycetemcomitans, Gram-negative bacteria, part of the normal flora of the mouth and throat, also cause endocarditis
Photomicrograph of newly hatched freshwater leech. Note multiple eyes at head and second attachment sucker at tail. Body length approx. 3 mm. Live specimen. Wet mount, 5X objective, transmitted 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.
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.
Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
