Thermo Scientific™ Rapid Urea Broth (Lyophilized)

Description

• Rapidly differentiate microorganisms on the basis of urease production with Thermo Scientific™ Remel™ Rapid Urea Broth (Lyophilized)
• In 1941 Rustigian and Stuart developed a medium for detection of urease activity by Proteus spp
• 1 They further observed that other urea-positive genera within Enterobacteriaceae could be detected in a medium with reduced buffering capacity 2
• Rapid Urea Broth provides such a medium and allows rapid urease detection in enteric gram-negative bacilli other than Proteus spp
• This medium is recommended by the American Public Health Association 3
• The detection of urease activity is routinely used in clinical microbiology to aid in identification of gram-negative bacteria
• Rapid Urea Broth (Lyophilized) is a medium recommended for use in rapid differentiation of microorganisms on the basis of urease production
• Microorganisms that hydrolyze urea by means of urease enzyme produce ammonia
• This alkaline end product causes the pH indicator, phenol red, to change color from yellow-orange to pink-red
• A balance of monopotassium phosphate and disodium phosphate comprise the buffering system to produce a rapid change in pH that changes phenol red indicator accordingly
• Easy to use – Lyophilized medium
• Reconstitute with 3mL demineralized water or neutral saline (pH 7.0 ± 0.2)
• Easy to interpret – A pink red color development indicates a positive test
• No color change indicates a negative test
• Recommended by the American Public Health Association (APHA) 3
