Healthy urine contains nitrates, a type of nitrogen chemical. When bacteria enter your urinary tract, the bacteria turn these nitrates into a different nitrogen chemical called nitrites. The medical term for nitrites in urine is nitrituria (NI-tri-tur-EE-ah). WebBacteria and cyanobacteria multiply by binary fission, a process in which a cell divides to form two identical daughter cells. Yeasts divide by budding, with a mother cell repeatedly forming single, identical but much smaller daughter cells.
