Abstract

Sve su nam više poznate interakcije između patogenih bakterija i protozoa. Neke bakterije postaju patogene tek nakon života unutar praživotinje. Protozoa je skupina unutar koje su neke vrste vrlo dobro prilagođene na razne uvjete na Zemlji. Pronađeno je da neke bakterije iskorištavaju tu rasprostranjenost protozoa u svoju korist i tako si šire areal. Također razvijaju složene patogene sposobnosti kako bi mogle zaraziti kompleksnije organizme. U ovome se radu koriste L. pneumophila i S. enterica kao uzorci patogenih bakterija, koje ulaze u simbiozu s protozoa (Acanthamoeba castellani i rod Tetrahymena). Ove interakcije su značajne za razvoj i preživljavanje tih bakterija. Nama su takva istraživanja bitna da bi mogli predvidjeti, a i potencijalno kontrolirati slijedeće korake patogenih bakterija.

Abstract (english)

Interactions between pathogenic bacteria and protozoa are becoming thoroughly understood. There are bacteria which become pathogenic only after they interact with a protozoa. Protozoa are microorganisms that are very well adapted to the various conditions on Earth today. It has been proven that a variety of bacteria are using these adaptations for their own advantages. These advantages are a wider living area under a big variety of environmental conditions and a more complex system of infection that allows them to infect more complex organisms. In this essay L. pneumophila and S. enterica are the two bacteria used as role models for prokaryotic and eukaryotic interactions, while in the same time Acanthamoeba castellani and the genus Tetrahymena are used as role models for these interactions as protozoans. Interactions between protozoa and bacteria have been well known of but it is only today that we are realizing their significance in bacteria development and survival. Research in this field may be vital for holding a dominant role against desease caused by pathogenic bacteria.
