Backgrounds of Bacteria and Mold under the microscope in Lab.
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.
PAPS Smear study of a young women under microscopy showing Atrophic changes in uterus which is unusual at young age.
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.
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
Green algae cells background
The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,
Cells in the body examined by endoscope
Close up 3D illustration of microscopic Cholera bacteria infection
High-grade serous ovarian carcinoma with SET features
Colored pollen grains of different species under the microscope.
Fetus with dna 3D rendering
Secreted by Staphylococcus aureus, this toxin binds with the outer membrane, with subsequent oligomerization of the toxin monomers to form water-filled channels. These are responsible for osmotic phenomena, cell depolarization and loss of vital molecules (v.gr. ATP), leading to cell death. 3D cartoon model in two purpendicular projections, chain id color scheme, based on PDB 3anz, white background.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
Microscopic view of a blood smear from leukemia patient showing many abnormal white blood cells, blood cancer cells or leukemia cells.
Liver Fluke Section under light microscope with white background
HER3 and the epidermal Growth Factor Receptor (EGFR) activate the  MEK/ERK (MAPK) signaling pathway. They play a  crucial role in cellular proliferation, survival, and differentiation. Dysregulation of this pathway is linked to cancer progression.
Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
Thermometer with a collection of assorted pills.  The thermometer reads Tripledemic instead of a temperature.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  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 abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Nucleosome, molecular model. 3D illustration. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins.
Cryptococcal pneumonia. Cryptococcal pneumonia is a fungal infection caused by Cryptococcus neoformans predominantly in immunosuppressed individuals and rarely in the immunocompetent population.
Dna structure on science background. 3d illustration
3D rendering of microscopic molecular structure
3D cartoon and Gaussian surface models, PDB 2j0D, white background.
What micro plastic is made of - Chemical ingredients.\nClose up of microplastic on finger concept of water pollution and global warming
Collection of horizontal or vertical banners with pathogenic bacterias and viruses. Virus under microscope. Fast multiplication of bacteria. Infection and microbe. 3d render
