Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.Balises :MicroorganismsAlpsQilian MountainsThese infectious particles were capable of passing through submicron filters that were known to capture bacteria; hence, a new discipline within microbiology was founded based on sub-microscopic entities that did not completely conform to Koch’s well-accepted scientific dogma.There emerged a Golden Age of Microbiology during which many agents of different infectious diseases were identified.
Conditions initially remained inhospitable for the potential development of life. CRISPR – clustered regularly interspaced short palindromic repeats – were first discovered in the sequences of DNA from Escherichia coli bacteria and described in 1987 by Ishino et al.Anton van Leeuwenhoek (1632-1723) had discovered microorganisms when, using microscopes, he found that uncountable billions of minute animalcules existed .The renaissance and enlightenment. Milder symptoms may be treated with corticosteroids but usually are prevented by switching to alternative antibiotics.
