This colorized negative stained transmission electron micrograph (TEM) shows recreated 1918 influenza virions that were collected from supernatants of 1918-infected Madin-Darby Canine Kidney (MDCK) cells cultures 18 hours after infection. To separate these virions, the MDCK cells are spun down (centrifugation), and the 1918 virus in the fluid is immediately fixed for negative staining. The solid mass in lower center contains MDCK cell debris that did not spin down during the procedure.

This highly-magnified negatively-stained transmission electron micrograph (TEM) revealed ultrastructural morphology of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV), which was formerly known as novel coronavirus. (MERS-CoV) was identified in 2012 as the cause of respiratory illness in people. Investigations are being done to figure out the source of MERS-CoV and how it spreads. So far, there are no reports of anyone in the US getting infected with MERS-CoV. Most people who got infected with MERS-CoV developed severe acute respiratory illness with symptoms of fever, cough, and shortness of breath. About half of them died. Some people were reported as having a mild respiratory illness. MERS-CoV has been shown to spread between people who are in close contact. Transmission from infected patients to healthcare personnel has also been observed. Clusters of cases in Saudi Arabia, Jordan, the UK, France, Tunisia, and Italy are being investigated.

Bacillus Koch (Bk) or Mycobacterium tuberculosis, it is responsible for tuberculosis. Tuberculosis is making a comeback due to the appearance of multi-resistant bacterial strains. Pulmonary tuberculosis (phthisis) is the most widespread, but there are bone disorders (Pott's disease, white tumor of the knee), renal, intestinal, genital, meningeal and skin disorders (tuberculomas).

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.
