Vesicular Stomatitis Indiana Virus, TEM


This negatively-stained transmission electron micrograph (TEM) revealed the presence of numerous negative-sense, single-stranded RNA ((-) ssRNA) vesicular stomatitis virus (VSV) virions. VSV is responsible for causing vesicular stomatitis in horses, cattle and pigs, however, this virus infects, and is transmitted by insects to its mammalian hosts. Note the bullet-like shape of these virions, which are very similar to other Rhabdoviruses. It has particular importance to farmers in certain regions of the world where it can infect cattle. This is because its clinical presentation is identical to the very important foot and mouth disease virus is zoonotic and leads to a flu-like illness in infected humans.
