nitrites and Pyuria

nitrites has been researched along with Pyuria in 21 studies

Nitrites: Salts of nitrous acid or compounds containing the group NO2-. The inorganic nitrites of the type MNO2 (where M=metal) are all insoluble, except the alkali nitrites. The organic nitrites may be isomeric, but not identical with the corresponding nitro compounds. (Grant & Hackh's Chemical Dictionary, 5th ed)

Pyuria: The presence of white blood cells (LEUKOCYTES) in the urine. It is often associated with bacterial infections of the urinary tract. Pyuria without BACTERIURIA can be caused by TUBERCULOSIS, stones, or cancer.

" In contrast to previous studies of African apes, this finding is coupled with the near absence of urinary nitrites, demonstrating pervasive levels of sterile pyuria."3.75Sterile pyuria in a population of wild white-handed gibbons (Hylobates lar). ( Beaman, BA; Dominy, NJ; Hesemeyer, WJ; Reichard, UH; Savini, T, 2009)

"Pyuria was detected in 13/17 patients with a positive nitrate test vs."1.34[Nitrite test in Pseudomonas aeruginosa urinary tract infections]. ( Aladjem, M; Goldman, M; Grisaru-Soen, G; Lazarovitch, T; Rosenfeld-Yehoshua, N, 2007)
