Diagnostic Stuarts Urea Broth Base 500g About

Diagnostic Stuart's Urea Broth Base, also known as Urea Broth Base, is a specialized medium used to detect urease production in bacteria. It's particularly useful for differentiating Proteus species from other enteric bacilli. Urease is an enzyme that some bacteria produce to break down urea, releasing ammonia and causing the medium to become alkaline. A positive result, indicated by a color change from yellow to pink or red due to the pH indicator phenol red, signifies urease production. Here's a more detailed breakdown:
  • Urease Test:This medium is used to test for the presence of urease, an enzyme that some bacteria produce to hydrolyze urea. 
  • Urea Utilization:Bacteria with urease produce ammonia from urea, which raises the pH of the medium and causes a color change in the indicator. 
  • Differentiation:Stuart's Urea Broth Base is helpful in distinguishing Proteus species, which are typically urease-positive, from other enteric bacteria like Salmonella and Shigella, which are often urease-negative. 
  • Principle:The broth contains urea, a substrate for urease, and a pH indicator like phenol red. If a urease-positive organism is present, it will break down urea, releasing ammonia and raising the pH, which is indicated by the color change in the phenol red. 
  • False Positives:Protein hydrolysis and excess amino acids can also lead to alkalinity and false positive reactions, so a control medium without urea is recommended. 
  • Commercial Availability:This broth is commercially available in various forms, including dehydrated powder and prepared tubes
