This thin-section transmission electron micrograph (TEM) revealed the ultrastructural appearance of a single virus particle, or virion, of measles virus. The measles virus is a paramyxovirus, of the genus Morbillivirus. It is 100-200 nm in diameter, with a core of single-stranded RNA, and is closely related to the Rinderpest and canine distemper viruses. Two membrane envelope proteins are important in pathogenesis. They are the F (fusion) protein, which is responsible for fusion of virus and host cell membranes, viral penetration, and hemolysis, and the H (hemagglutinin) protein, which is responsible for adsorption of virus to cells. There is only one antigenic type of measles virus. Although studies have documented changes in the H glycoprotein, these changes do not appear to be epidemiologically important (ie no change in vaccine efficacy has been observed).

This stained transmission electron micrograph (TEM), captured by F.A. Murphy in 1968, depicts a number of Marburg virus virions, which had been grown in an environment of tissue culture cells. Marburg hemorrhagic fever is a rare, severe type of hemorrhagic fever which affects both humans and non-human primates. Caused by a genetically unique zoonotic (that is, animal-borne) RNA virus of the filovirus family, its recognition led to the creation of this virus family. The four species of Ebola viru

This colorized negatively-stained transmission electron micrograph (TEM) captured some of the ultrastructural details exhibited by the new influenza A (H7N9) virus. On April 1, 2013, the World Health Organization (WHO) first reported 3 human infections with a new influenza A (H7N9) virus in China. Since then, additional cases have been reported. Most reported cases have severe respiratory illness and, in some cases, have died. At this time, no cases of H7N9 outside of China have been reported. This new H7N9 virus is an avian (bird) influenza (flu) virus. Human infections with avian influenza (AI, or bird flu) are rare but have occurred in the past, most commonly after exposure to infected poultry. However, this is the first time that this bird flu subtype (H7N9) has been found in people. This virus is very different from other H7N9 viruses previously found in birds.

Agent of feline leucosis, a fatal viral disease specific to cats. This electron micrograph depicts the retrovirus, Feline Leukemia Virus (FeLV). FeLV is a very common, often fatal feline disease passed from one cat to another via adversarial bites, or when one cat sneezes on another, or shares a food bowl. A cat may be vaccinated in order to protect it from acquiring this virus. See image n1302105 on the site.

Influenza virus. Influenza A virus causes flu in humans, swine, birds, horses and dogs. Which species the virus will infect is determined by the glycoprotein spikes on its outer envelope. They are many strains of influenza A virus, among which the avian flu virus (H5N1), swine flu (H1N1) or human. Transmission Electron Micrograph (TEM).

This transmission electron microscope image shows SARS-CoV-2, the virus that causes COVID-19, isolated from a patient in the United States. Virus particles (golden round objects) emerge from the surface of cells cultured in the laboratory. The spikes on the outer edge of the virus particles give coronaviruses their crown-shaped name.
