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.
Cryptococcus neoformans fungus, computer illustration. C. neoformans is a yeast-like fungus that reproduces by budding. An acidic mucopolysaccharide capsule completely encloses the fungus. It can cause the disease cryptococcosis, especially in immune deficient patients, such as those with HIV/AIDS (acquired immunodeficiency syndrome). It can infect the brain, causing meningitis or brain abscesses, lungs or skin. The most common clinical form is meningoencephalitis. It is caused by inhaling the fungus from soil that has been contaminated by pigeon droppings.

A quadrant streak of the bacterium Staphylococcus aureus cultured or inoculated on Baird-Parker agar with egg tellurite .
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.

Overnight culture of lactose non-fermenting  E.coli STEC O157:H7 producing Shigatoxin. Shiga toxin-producing E.coli (STEC) strains can cause serious illness. Most patients were infected through contaminated food; however STEC can also spread among people and family outbreaks are not uncommon.

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
Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange),  that is aggregated to amyloid beta fibrils, which build up amyloid plaques.

Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
A new antibiotic (zosurabalpin, red) traps lipopolysaccharide (orange) in the intermembrane transporter of the Gram-negative bacterium Acinetobacter baylyi
Lymphocytic myocarditis. Myocarditis is an inflammation of the heart muscle. Lymphocytic refers to the type of cell seen in the affected tissue. A lymphocyte is a type of immune function cell.
Microscopic view of Salmonella enterica serotype Typhi that causes typhoid fever. 3D illustration
Photomicrograph of rotifer. Rapidly rotating cilia at top of head, internal organs visible. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Host cells with spores (mold) are inside wood under the microscope for education.
Squash preparation of plant cells stained to reveal chromosomes, various stages of mitosis are visible. 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 aberration is inevitable in light microscopy, but has been kept to a minimum in this image.
