Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this highly magnified, digitally colorized transmission electron microscopic (TEM) image highlights the particle envelope of a single, spherical shaped, Middle East respiratory syndrome coronavirus (MERS-CoV) virion, through the process of immunolabeling, the envelope proteins, using rabbit HCoV-EMC/2012 primary antibody, and goat anti-rabbit 10nm gold particles.

This illustration depicts a three-dimensional (3D), computer-generated image of a cluster of barrel-shaped, Clostridium perfringens bacteria. The artistic recreation was based upon scanning electron microscopic (SEM) imagery. See PHIL 21914, for another view of these microbes.

This illustration depicted a three-dimensional (3D), computer-generated image, of a group of Gram-positive, Corynebacterium diphtheriae, bacteria. The artistic recreation was based upon scanning electron microscopic (SEM) imagery.

This illustration, created at the Centers for Disease Control and Prevention (CDC), reveals ultrastructural morphology exhibited by coronaviruses. Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically. A novel coronavirus, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19).

Based on electron microscopic (EM) imagery, this three-dimensional (3D) illustration provides a graphical representation of a single norovirus virion, set against a beige background. The different colors represent different regions of the organism’s outer protein shell, or capsid.

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally colorized scanning electron microscopic (SEM) image depicts four, yellow colored, Group A Streptococcus (GAS), Streptococcus pyogenes bacteria, which were atop the surface of a human white blood cell (WBC), known as a neutrophil.

The Lambert Glacier in Antarctica is the world's largest glacier. The focal point of this image is an icefall that feeds into the glacier from the vast ice sheet covering the polar plateau. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as it bends and twists on its slow-motion descent 1300 feet (400 meters) to the glacier below.

This scar on an arid landscape is the dry riverbed of the Ghadamis River in the Tinrhert Hamada Mountains near Ghadamis, Libya.

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this highly magnified, digitally colorized scanning electron microscopic (SEM) image, revealed ultrastructural details at the site of interaction of numerous yellow colored, Middle East respiratory syndrome coronavirus (MERS-CoV) viral particles, located on the surface of a Vero E6 cell, which had been colorized blue.
