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.

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.

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.
A plant cell is a fundamental unit of plant life, containing various organelles, including the cell wall, chloroplasts, and a large central vacuole, which are unique to plant cells. These cells serve as the building blocks of plants and play essential roles in photosynthesis, growth, and structural support.
