Early and prompt diagnosis of pyelonephritis is of great importance in children. The aim of this study is to evaluate the diagnostic accuracy of urinary carbohydrate antigen 19-9 (CA19-9) levels for predicting acute pyelonephritis (APN) in children with urinary tract infection (UTI). Patients were
The fine structural details of how leukocytes appear in the lumen of tubules and the localization of bacteria in the tubulo-interstitial space were studied by light and electronmicroscopy in renal cortical biopsy specimens from three patients with acute pyelonephritis. The cells of interstitial
The commonest organism in urinary tract infections (UTI) is Escherichia coli. Pyelonephritogenic E.coli strains possess P-fimbriae which firmly attach to uroepithelial cells by recognition of a carbohydrate structure, alpha-D-Galp-(1-4)-beta-D-Galp, which is confined within all glycosphingolipids
Uropathogenic Escherichia coli (UPEC) strains are a leading cause of infections in humans, but the mechanisms governing host colonization by this bacterium remain poorly understood. Previous studies have identified numerous gene clusters encoding proteins involved in sugar transport, in
Earlier investigations have shown that pyelonephritic Escherichia coli specifically recognize and bind to carbohydrate structures correlated to the P blood group antigens. These findings are confirmed and extended in this study. Twenty-two of 23 nonselected E. coli strains from children with acute
Uropathogenic E. coli exploit PapG-II adhesin for infecting host cells of the kidney; the expression of PapG-II at the tip of bacterial pili correlates with the onset of pyelonephritis in humans, a potentially life-threatening condition. It was envisaged that blocking PapG-II (and thus bacterial
Most human pyelonephritis Escherichia coli isolates express both mannose (MS)- and globoside (Gal-Gal)-binding pili. An ascending E. coli urinary tract infection model was established in the 16-wk-old female BALB/c mouse to compare the pathogenic significance of MS and Gal-Gal pili and their
C5a receptor 1 (C5aR1) is a G protein-coupled receptor for C5a and also an N-linked glycosylated protein. In addition to myeloid cells, C5aR1 is expressed on epithelial cells. In this study, we examined the role of C5aR1 in bacterial adhesion/colonization of renal tubular epithelium and addressed
Escherichia coli strains associated with extra-intestinal infections frequently express carbohydrate binding adhesins which are present as minor components of pili. The adhesin protein, PapG, and at least two other minor pilus subunits, PapE and PapF, are associated with the tips of Gal alpha
This review article discusses the stages in the development of research on group B streptococcus (GBS), otherwise called Streptococcus agalactiae. Emphasis was placed on the bacteriology, clinical spectrum of disease, immunity to GBS infections and antibiotic susceptibility of the causative
We studied the nutritional and metabolic features of Eubacterium suis, an anaerobic animal pathogen that causes cystitis and pyelonephritis in pigs. Peptone-yeast extract-starch (PYS) medium, which contained Trypticase (BBL Microbiology Systems), yeast extract, starch, minerals, cysteine, and sodium
A case of hydronephrosis caused by renal stones with elevated serum levels of carbohydrate antigens 19-9 (CA-19-9) and 125 (CA-125) is reported. A 74-year-old woman was hospitalized with pyelonephritis. The results of computerized tomography and endoscopy suggested that the patient did not have
A number of different bacterial strains were analyzed for the presence of common antigens using immunodiffusion techniques. Most of the studied E. coli strains had many common antigens. Especially one antigen was found in all investigated E. coli as well as Proteus and Pseudomonas strains and
A middle aged African-American woman with a stable history of carnitine palmitoyl transferase II (CPT II) deficiency presented with myalgias for 1 week. Physical examination and laboratory findings were consistent with severe sepsis secondary to pyelonephritis leading to rhabdomyolysis. Subsequent
Measurement of cytokine concentrations within body fluids is a means of recognizing subclinical and/or unresolved, infectious and inflammatory states in patients. In the urinary tract, such information may be useful for identifying patients with pyelonephritis, asymptomatic bacteriuria, recurrent
