Urease Test

This test is used to identify bacteria capable of hydrolyzing urea using the enzyme urease. It is commonly used to distinguish the genus Proteus from other enteric bacteria. The hydrolysis of urea forms the weak base, ammonia, as one of its products. This weak base raises the pH of the media above 8.4 and the pH indicator, phenol red, turns from yellow to pink. Proteus mirabilis is a rapid hydrolyzer of urea (center tube pictured here). The tube on the far right was inoculated with a urease negative organism and the tube on the far left was uninoculated.

-
Freddie Mercury's final days in 1991 remain enshrined in mystery, nearly 30 years on. The Queen frontman succumbed to his battle with Aids on November 24, having released a public statement just 24 hours previously that confirmed he was HIV+. Rumours had been swirling about his health status for a number of years, with speculation that he had been tested for HIV and Aids as far back as 1986, after his health declined so rapidly that Queen had to halt their 1987 Magic Tour before it was due to finish.
