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.

Diffuse large B-cell lymphoma, or DLBCL, is a cancer that starts in white blood cells called lymphocytes.
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
In vitro bacterial culture
p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.

Candida albicans grown on chromogenic agar plates. Candida albicans, a fungus naturally present in small quantities on the body, inhabits areas such as the mouth, skin, and intestines. When the balance with healthy bacteria is disrupted, Candida can lead to infections like thrush and vaginal yeast infections. These infections are frequent and typically addressed with antifungal medications.

Close-up shot of a petri dish for checking an antibiotic in the laboratory.
Coxsackie virus internal structure, 3d illustration set isolated on white
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
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.

Shiny artificial molecular structure in many colors. Horizontal composition, isolated on black background.
Dna structure on science background. 3d illustration
Close-up shot of a petri dish for checking an antibiotic in the laboratory.
From left to right: the NMDA and AMPA receptors transport calcium cations into neurons after being activated by the neurotransmitter glutamate and the GABA receptor (right) transport chloride anions after the activation by gamma aminobutyrate. PDB entries: 6wht, 3kg2, 6d6u
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.
