Urease positive means that an organism can produce the enzyme urease, which reacts with urea to produce ammonia and carbon dioxide. This reaction can be detected by the change in pH of the media, typically turning it pink or red. Urease positivity is often used in microbiology to help identify certain bacterial species.
