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.
Freshwater Closterium algae (unicellular charophyte green algae) - optical microscope x200 magnification
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 close view of high vaginal swab Gram stain smear, 100x. diagnosis of Bacterial vaginosis (BV).
Squash preparation of stained onion root tip cells showing late telophase and metaphase stages of mitosis. Bright field illumination on a Leica microscope, Image taken with the X100 objective lens.  Depth of focus is extremely shallow (less than one micron).  Optimum setting of the aperture for maximum resolution and good contrast. Chromatic aberation is inevitable in light microscopy, especially at this scale of magnification, but has been kept to a minimum in this image.

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
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.

Burkitt lymphoma is a form of non-Hodgkin's lymphoma in which cancer starts in immune cells called B-cells. Recognized as a fast growing human tumor, Burkitt lymphoma is associated with impaired immunity and is rapidly fatal if left untreated.

Pyracantha is a genus of thorny evergreen large shrubs in the family Rosaceae, with common names Firethorn or Pyracantha. They are native to an area extending from Southeast Europe east to Southeast Asia, resemble and are related to Cotoneaster, but have serrated leaf margins and numerous thorns (Cotoneaster is thornless).\nPyracanthas are valuable ornamental plants, grown in gardens for their decorative flowers and fruit, often very densely borne. Their dense thorny structure makes them particularly valued in situations where an impenetrable barrier is required. Pyracantha berries are not poisonous as commonly thought; although they are very bitter, they are edible when cooked and are sometimes made into jelly.[2] In the UK and Ireland Pyracantha and the related genus Cotoneaster are valuable sources of nectar when often the bees have little other forage during the June Gap.\nThe plants reach up to six metres tall. The seven species have white flowers and either red, orange, or yellow berries. The flowers are produced during late spring and early summer; the pomes develop from late summer, and mature in late autumn (source Wikipedia).
