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.

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.

Cardiac sarcoidosis is a rare condition which affects a small number of people who suffer from a condition called sarcoidosis – an inflammatory condition that can affect multiple organs. The disease tends to affect younger people, generally between 25 and 45 years old. Sarcoidosis is characterized by the presence of granulomas. These are ball-like collections of inflammatory cells that cluster around and react to a foreign substance. The inflammation associated with granulomas can damage virtually every part of the heart, including the electrical system, muscle, valves, arteries and surrounding tissue called the pericardium.
