FIG. 1. Urea agar test results. Urea agar slants were inoculated as follows: (a) uninoculated, (b)Proteus mirabilis (rapidly urease positive), (c) Klebsiella pneumoniae (delayed urease positive), (d)Escherichia coli (urease negative). All samples were incubated at 37 oC for 16 hours. Stuart’s Urea Broth (4, 5)
• Understand the biochemical basis of the urease test; • Properly perform the urea test and distinguish between positive and negative reactions; and • Discern how this information can be used to differentiate and identify microbial species. Figure 1. Urease Test Results. The three tubes contain rehydrated Urease Test tablets. The left ...

21 kwi 2023 · Of the pathogenic Klebsiella species, K. pneumoniae is the most prevalent and clinically important. Infections with K. pneumoniae are usually hospital-acquired and occur primarily in patients with impaired host defenses.
The objectives are to determine the frequency of UTIs with Klebsiella pneumoniae in CKD, assessing clinical forms of the chronic kidney disease, favorable factors, co-morbidities and the influence of the infection on the evolution of chronic kidney failure and the degree of antibiotic susceptibility of uropathogenic K. pneumoniae.
Klebsiella pneumoniae usually shows up as positive in the urease test, meaning that the urease enzyme is present. The medium changes color and the pH rises as a result of this enzyme hydrolyzing urea to create ammonia and carbon dioxide.
