Free Download or read online Medical Urdu Book " Jarasim (virus)" By C. V. Subramanian translated in Urdu by Shareef Ahmed Khan. An infection is a little irresistible operator that recreates just inside the living cells of different life forms. Infections can taint numerous types of life structures, from creatures and plants to microbes and archaea.Since Dmitri Ivanovsky's 1892 article depicting a non-bacterial pathogen contaminating tobacco plants, and the revelation of the tobacco mosaic infection by Martinus Beijerinck in 1898,around 5,000 infections have been portrayed in detail, despite the fact that there are a large number of diverse types. Viruses are found in practically every environment on Earth and are the most bottomless sort of natural element. The investigation of infections is known as virology, a sub-claim to fame of microbiology.
