Chronic kidney disease (CKD) has long been known to cause significant gastrointestinal and colonic pathology. Recent advances in understanding of the role of colonic bacterial microbiome and its function and composition in health and disease have revealed previously unappreciated effects of CKD-associated colonic pathology on the development of uremic complications. CKD can result in profound c...

A urease color test fluid medium (U-9) for the detection and identification of T (T-strain) mycoplasmas in clinical material is described which is sensitive and specific for this group of mycoplasmas. The medium was prepared from commercially available components and contained 95% half-strength, tryptic digest broth (pH 5.5), 4% unheated horse serum, 0.05% highest-purity urea, 0.001% sodium phe...

objectives the aim of this study was to perform a histopathological and bacteriological evaluation of gastric lesions based on h. pylori and helicobacter-like organisms (hlos) in cats. materials and methods the present study was carried out on 28 cat’s (13 male and 15 female cases) gastric mucosae, which were tested by bacteriological and histopathological methods. biochemical tests such as cat...

Campylobacter sputorum is a nonthermotolerant campylobacter that is primarily isolated from food animals such as cattle and sheep. C. sputorum is also infrequently associated with human illness. Based on catalase and urease activity, three biovars are currently recognized within C. sputorum: bv. sputorum (catalase negative, urease negative), bv. fecalis (catalase positive, urease negative), and...

BACKGROUND Intestinal microbiome constitutes a symbiotic ecosystem that is essential for health, and changes in its composition/function cause various illnesses. Biochemical milieu shapes the structure and function of the microbiome. Recently, we found marked differences in the abundance of numerous bacterial taxa between ESRD and healthy individuals. Influx of urea and uric acid and dietary re...

The aim of the study was to evaluate the suitability of a modified one minute rapid urease test (one day rapid urease test) as a low cost H. pylori detection method. A sample of 205 patients clinically suspected of having H. pylori infection was tested. One day rapid urease test and histology based H. pylori tests (the gold standard) were performed on endoscopic antral biopsies. There were 6 tr...

color from ammonia was produced by an additional 5 min of incubation at 37 C. All strains of Proteus, except those of P. inconstans, generated detectable amounts of ammonia (Table 1). None of the Escherichia organisms was urease-positive. These findings were identical with those yielded by the urease technique of Stuart et al. The sensitivity of the Berthelot color reaction permits detection of...

Some series of arylidene barbiturates and thiobarbiturates were evaluated for their antibacterial, antioxidant, and urease inhibition activities. The arylidene barbiturates and thiobarbiturates were tested for antimicrobial activity using the agar well diffusion technique against 13 bacteria. The synthesized compounds (1a-g) were screened for antiurease and antioxidant activities. The results s...

Streptococcus salivarius 57.I is one of the most abundant and highly ureolytic bacteria in the human mouth. It can utilize urea as the sole nitrogen source via the activity of urease. Complete genome sequencing of S. salivarius 57.I revealed a chromosome and a phage which are absent in strain SK126.
