Transmition Electron microscopy of an epithelial cell where mitochondria of several sizes can be seen with the characteristic double membrane and internal cristaes. Mitochondria are believed to be of bacteria origin. It has its own genome and RNA and protein which are similar to those of bacteria.
plant Stem-Collenchyma C.S. under light mircoscope with white background
Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
amazing inhabitants of the microworld under a microscope
Photomicrograph of Volvox globator, a green algae. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
In vitro bacterial culture
Symbolic illustration of infectious viruses under the microscope, for example influenza viruses, smallpox, measles or similar. Medical research and investigation of diseases and healthcare concept.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Transmission electron micrograph (TEM) showing a desmosome (macula adherens) with prominent dense plaques where keratin intermediate filaments were attached.
stx2a is a subtype of Shiga toxin-producing E. coli (STEC) linked to Hemolytic Uremic Syndrome (HUS), a severe condition impacting kidney function and blood clotting. STEC poses a significant risk of foodborne illness and can spread within communities including family members.

Algae under microscopic view, Diatoms, phytoplankton, fossils, silica, golden yellow
microscopic cross section showing the Adrenal gland of a rat
In vitro bacterial culture
Epidermis. Electron microscope micrograph of an epidermis spinous layer. The keratinocytes show polygonal shapes, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous desmosomes crossing the intercellular spaces.
WHO says that it is estimated that ETEC causes about 220 million diarrhoea episodes globally, with about 75 million episodes in children under 5 years of age, resulting in between 18 700 and 42 000 deaths in children younger than 5 years. Several vaccines are in the pipeline.\nETEC is also a very common cause of traveler's diarrhea, this infection is usually self limiting, with no need for antibiotics. ETEC is common in developing countries.
Abstract designed black, gray and white wallpaper background image for computer desktops.
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.
An electron image represents several nanoparticles made of lipids (liposomes) containing an anticancer drug (doxorubicin)
Perfect shape of sponge cake.
Microscopic image of urine granular cast and cellular cast, cause of exercise or dehydration Acute tubular necrosis. kidney diseases.
In vitro bacterial culture
Transmission electron microscope (TEM) micrograph showing of a kidney convoluted tube cell. The basal infoldings with numerous mitochondria associated can be seen. Dense bodies are lysosomes.
Life-threatening infections are on the rise due to drug-resistant bacteria. Carbapenemase-producing organisms (CPO) are bacteria that have become resistant to a group of antibiotics known as carbapenems. CPO are emerging pathogens world wide.
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Host cells with spores (mold) are inside wood under the microscope for education.
