Urea-hydrolyzing Vibrio parahaemolyticus associated with acute gastroenteritis.
A case of gastroenteritis caused by a urea-hydrolyzing strain of Vibrio parahaemolyticus is presented. Urea-hydrolyzing strains of Vibrio parahaemolyticus have rarely been reported and have not been described previously as a cause of gastroenteritis in the United States. With the exception of urea hydrolysis and the methyl red test, the isolate had all the characteristics of V. parahaemolyticus...
متن کاملLuminometric single step urea assay using ATP-hydrolyzing urease.
An automatic enzyme kinetic luminometric method for determination of small quantities of urea in biological fluids and in microdialysates is presented. The method is based on the ATP-hydrolyzing urease reaction [urea amidohydrolase (ATP-hydrolyzing); EC 3.5.1.45], monitored by a luciferin-luciferase ATP reaction. The assay range is 100 pmol to 50 nmol with a detection limit of 5 micromol/L in t...
متن کاملPurification and characterization of a methylene urea-hydrolyzing enzyme from Rhizobium radiobacter (Agrobacterium tumefaciens)
Slow-release fertilizers are gaining acceptance to increase fertilizer use efficiency and reduce environmental impact. The release of nitrogen from methylene urea, a common slow release N fertilizer, is controlled by microbial decomposition. An enzyme hydrolyzing slowrelease nitrogen fertilizer, methylene urea, was purified from Rhizobium radiobacter (Agrobacterium tumefaciens) to homogeneity u...
متن کاملUrea Tests of Renal Efficiency. I. by I. M. Rabinowitch
The urea tests of renal efficiency commonly mentioned in the literature include (a) simple estimation of blood urea concentration, (b) determination of urine urea concentration following ingestion of urea, and (c) observations on the relationship between blood and urine urea concentrations. From a comparative study of these three methods, the general conclusion reached in this hospital (1) was ...
متن کاملStarch hydrolyzing streptococci.
The ability to hydrolyze starch is a property that is scattered among streptococcal species in 3 of the 4 physiological divisions described by Sherman (1937), the exception being members of the Enterococcus. A single reference to a starch hydrolyzing enterococcus is Mann's (Mann et al., 1954) report of a "starch-fermenting Streptococcus faecalis." Outstanding among the nonhemolytic streptococci...
