Question

who is the founder of the virus​

Answer 1

Answer:

The history of virology – the scientific study of viruses and the infections they cause – began in the closing years of the 19th century. Although Louis Pasteur and Edward Jenner developed the first vaccines to protect against viral infections, they did not know that viruses existed. The first evidence of the existence of viruses came from experiments with filters that had pores small enough to retain bacteria. In 1892, Dmitri Ivanovsky used one of these filters to show that sap from a diseased tobacco plant remained infectious to healthy tobacco plants despite having been filtered

Answer 2

Answer:

$\huge \tt \red{ANSWER}$

The name virus was coined from the Latin word meaning slimy liquid or poison. It was originally used to described any infectious agent, including the agent of tobacco mosaic disease, tobacco mosaic virus. In the early years of discovery, viruses were referred to as filterable agents. Only later was the term virus restricted to filterable agents that require a living host for propagation.

• 1892 – Dimitrii Ivanovsky observed that agent of tobacco mosaic disease passes through porcelain filters that retain bacteria

• 1898 – Marcus Beijerinck makes the same observation; concludes that the pathogen must be a distinctive agent

• 1898 – Friedrich Loeffler and Paul Frosch (former students of Koch), find that causative agent of foot-and-mouth disease is filterable (the first animal virus)

• 1901 – Yellow fever virus – Walter Reed (the first human virus)

• 1903 – Rabies virus (Remlinger, Riffat-Bay)

• 1906 – Variola virus (Negri)

• 1908 – Poliovirus (Karl Landsteiner and E. Popper); chicken leukemia virus (Ellerman, Bang)

• 1911 – Rous sarcoma virus (Peyton Rous)

• 1915 – Bacteriophages -Frederik Twort, Felix D’Herelle
