The importance of tobacco mosaic virus in the history of viruses cannot be overstated. It was the first virus to be discovered, and the first to be crystallised and its structure shown in detail. The first X-ray diffraction pictures of the crystallised virus were obtained by Bernal and Fankuchen in 1941.
Martinus Beijerinck coined the term of "virus" to indicate a non-bacterial nature of the tobacco mosaic disease. In 1935, the tobacco mosaic virus was the first virus to be crystallized. Despite the erroneous conclusion, Mayer's pioneer work on the tobacco mosaic disease served as an important step in the discovery of viruses and led to the ...

Deaths probably numbered in the tens or perhaps over a hundred million, with perhaps 90% of the population dead in the worst-hit areas. Lack of scientific knowledge about microorganisms and lack of surviving medical records for many areas makes attribution of specific numbers to specific diseases uncertain.
Carlos Justiniano Ribeiro Chagas, or Carlos Chagas (Portuguese: [ˈkaʁluz ʒustʃĩniˈɐ̃nu ʁiˈbejɾu ˈʃaɡɐs]; July 9, 1879 – November 8, 1934), was a Brazilian sanitary physician, scientist, and microbiologist who worked as a clinician and researcher.
Scientists made an unexpected discovery in a Massachusetts forest: a collection of “giant” viruses many times larger than typical viral specimens.
A number of “vampire viruses” have been discovered in soil samples in Maryland and Missouri for the first time.. The existence of the eerily-nicknamed viruses has been known to researchers for ...
A disease which can kill cats, both domestic and wild, has been discovered for the first time in the US. A variant of the rustrela virus-- related to the wider-known rubella virus which causes a ...
