Zbog sve veće rezistencije bakterija na poznate antibiotike, u novije vrijeme provodi se niz istraživanja s ciljem pronalaženja prirodnih tvari, posebice biljaka, koje bi mogle pomoći u prevenciji i liječenju urinarnih infekcija koje se tretiraju antibioticima. Urinarne infekcije su upalne bolesti kojima su podložne sve dobne skupine i čine druge najčešće bakterijske infekcije kod ljudi. Češće se javljaju u žena i uglavnom ih uzrokuju gram negativne bakterije. Najčešći uzročnik je Escherichia coli. Uz liječenje antibioticima, često se koriste i pripravci ljekovitog bilja. Cilj rada je dati pregled istraživanja učinkovitosti zimzelene medvjetke, obične planike i brusnice u liječenju urinarnih infekcija.Due to the increasing resistance of bacteria to antibiotics, a number of studies have been conducted to find natural substances, especially plants, which could help prevent and treat urinary tract infections. Urinary infections are inflammatory diseases that are susceptible to all age groups and are the second most common bacterial infections in humans. They are more likely to occur in women and are generally caused by gram negative bacteria. The most common cause is Escherichia coli. With the treatment of antibiotics, medicinal herbs are often used. The aim of the paper is to give an overview of the study of the efficacy of bearberry tree, the strawberry tree and cranberries in the treatment of urinary infections
