Urea splitting bacteria are related to the formation of struvite or apatite. We investigated the urease activity of bacteria by two methods; the direct measurement of urease activity of viable bacteria and sonicated bacteria from amounts of ammonia by the indophenol method, and the measurement of urease activity by alkalization of infected urine. Proteus mirabilis and Pseudomonas aeruginosa had moderate activity of urease, and Morganella morganii and Staphylococcus epidermidis had the most powerful activity. P. mirabilis caused the strongest alkalization in infected urine.
