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.

Microscopic photograph of a professionally prepared slide demonstrating vulvar malignant melanoma. Melanomas of the vulva and vagina are rare, accounting for no more that 2% of melanomas among women. Melanoma of the vulva behaves like melanoma in any other location and may affect a much younger population.
