Photomicrograph of Paramecium caudatum. Consists of only one cell. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Freshwater aquatic zooplankton and algae under microscope view
Epithelial Cells in urine sediment.
plant Zea Stem C.S. under light mircoscope with white background
Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.
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.
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
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.
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.
Trematode parasite under a microscope
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.
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
Mix eggs of parasite.in stool exam.
Natural agate surfaces, suitable for backgrounds and wallpapers.
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.
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.
Paramecium caudatum is a genus of unicellular ciliated protozoan and Bacterium under the microscope.
Taenia Pisiformis Section under light microscope with white background
Demodex folliculorum - parasitic mite on the eyelashes of a human eye, microscope
Cheyletiella blakei Mite - Small Cat pest view under a microscope
Volvox sp. algae under microscopic view, dark background
Some amoebas like this one form shells. Shell is composed of bits of rock (sand), diatom shells, and other debris. Fresh water. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Lepocinclis acus or euglena acus, a single cell flagellate eukaryote under the microscope
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.
Synedra ulna (unicellular freshwater diatom algae) under the microscope - optical microscope x400 magnification
Abstract Crystal background marble shot, nature pattern.
Euglena is a genus of single-celled flagellate Eukaryotes under microscopic view for education.
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.
Microscopic image of urine granular cast and cellular cast, cause of exercise or dehydration Acute tubular necrosis. kidney diseases.
