Abstract
Virusi su male infektivne čestice promjera 10-100 nm. Nemaju vlastiti metabolizam, a genom im je reduciran samo na gene potrebne za preuzimanje stanične mašinerije stanice domaćina. Ovakva definicija virusa usmjeravala je virologe desetljećima sve do otkrića prvog gigantskog virusa 2003. godine. Do tada smatrani intracelularnim bakterijskim parazitima, gigantski virusi mogu dosegnuti veličinu od 400 nm do 1 µm, čime su neki veći od tipičnih bakterija. Njihov genom kodira na stotine gena, od kojih su neki obilježje staničnog metabolizma. Gigantski virusi su prisutni na gotovo svim staništima, kao što su oceani, tlo, kopnene i boćate vode, vodovodne cijevi, spremišta vode, u probavilu životinja i sl. Smatra se da gigantski virusi imaju značajan utjecaj na ekologiju svih navedenih staništa, no bili su previđeni zbog svoje zavaravajuće morfologije. Gigantski virusi su jedini virusi koji imaju vlastite parazite, malene viruse - virofage. Virofagi su virusi dimenzija oko 50 nm koji proliferiraju jedino u prisutnosti odgovarajućeg gigantskog virusa, ometajući njegovu proliferaciju.
Abstract (english)
Viruses are small infectious particles with a diameter of 10-100 nm. They have no metabolism of their own and their genome is reduced to the genes necessary to take over the cellular machinery of the host cell. This definition of a virus guided virologists for decades until the first giant virus was discovered in 2003. Until then, they were considered intracellular bacterial parasites. Giant viruses can range in size from 400 nm to 1 µm, making some larger than typical bacteria. The genome encodes hundreds of genes, some of which are hallmarks of cellular metabolism. Giant viruses are found in almost all habitats, e.g., in the oceans, soil, terrestrial and brackish waters, aquifers, water reservoirs, animal digestive tracts, etc. Giant viruses are thought to have a significant impact on the ecology of all these habitats, but because of their deceptive morphology they have been overlooked. Giant viruses are the only viruses that have their own parasites, tiny viruses - virophages. Virophages are viruses about 50 nm in size that replicate only in the presence of a corresponding giant virus and inhibit its replication.
