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.
centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification
Orange Square wooden box filled with orange book replicas
grey book isolated on white, blue frame for title on the spine
Pattern Design on Banknote
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.
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.
Transmission electron microscope micrographs showing the aspect of muscle fiber sarcomere components in longitudinal (below) and transverse (above) sections at the Z-line, I and A bands and H zone
pokeberry root, poke root, Radix Phytolaccae
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.
Algae under microscopic view, Diatoms, phytoplankton, fossils, silica, golden yellow
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.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Photomicrograph of Volvox globator, a green algae in various stages of development. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
plant stem (dahlia stem) cross section under the microscope showing epidermis, bascular bundles (phloem and xylem) cortex and pith - optical microscope x100 magnification
Old orange and black scuffed damaged marbled paper, Original over 150+ years old
Demodex mange from a microscope view. The parasite causing a skin disease -Demodecosis.
Blue Square wooden box filled with blue book replicas
Close up Plant epidermis with stomata or Leaf Epidermis (Stomata) under microscope.
