The objectives of this study were to describe the in vitro antimicrobial susceptibility and clinical significance of Proteus mirabilis in canine bacteriuria and to identify the risk factors associated with P. mirabilis urinary tract infections. This is a retrospective
OBJECTIVE
patients with rheumatoid arthritis (RA) are reported to have in their sera raised levels of antibody specific to Proteus mirabilis. The aim of the study was to verify this and to determine an explanation for it by investigating the frequency of P. mirabilis urinary tract infection in RA
We performed a retrospective extended-spectrum β-lactamase (ESBL) molecular characterization of Proteus mirabilis isolates recovered from urine of spinal cord injury patients. A incorrectly detected TEM-24-producing clone and a new weakly expressed TEM-derived ESBL were discovered. In such patients,
The in vitro attachment of 335 Proteus mirabilis strains from various human sources to human urinary tract epithelial cells was measured. No significant difference in adhesive capacity was found between P. mirabilis strains isolated from the blood of 89 patients with bacteremia, the stools of 36
Elevated serum antibody titers against Escherichia coli and/or Proteus mirabilis were found in 35% of 89 patients with a conduit urinary diversion. Statistical analysis showed significant correlation between the titers and growth of E. coli or P. mirabilis in conduit urine. But 17 (24%) of 72
Proteus mirabilis, a common agent of nosocomially acquired and catheter-associated bacteriuria, can cause acute pyelonephritis. In ascending infections, bacteria colonize the bladder and ascend the ureters to the proximal tubules of the kidney. We postulate that Proteus species uses the HpmA
Proteus mirabilis, a significant cause of bacteriuria and acute pyelonephritis in humans, produces urease. This high-molecular-weight, multimeric, cytoplasmic enzyme hydrolyzes urea to ammonia and carbon dioxide. To assess the role of urease in colonization, urolithiasis, and acute pyelonephritis in
This study aimed to analyze the proinflammatory cytokine mRNA expression in the urinary tract of BALB/c mice infected with bacterial strains with uropathogenic potential. Groups of four 6-week-old female BALB/c mice were intraurethrally inoculated with 5 × 107 colony-forming units (CFU)
Normal vaginal fluid from premenopausal volunteers was inoculated with 10 strains of Proteus mirabilis and 14 strains of Pseudomonas aeruginosa at pH's of 4.3, 4.6 and 4.9. All bacteria were killed at pH 4.3. Nine of 10 strains of Proteus mirabilis and 12 of 14 Pseudomonas aeruginosa were killed at
Proteus mirabilis, a common agent of bacteriuria in humans, causes acute pyelonephritis and bacteremia. Renal epithelium provides a barrier between luminal organisms and the renal interstitium. We have hypothesized that P. mirabilis may be internalized into renal epithelium. To test this hypothesis,
Proteus mirabilis, a common cause of urinary tract infection, can lead to serious complications including pyelonephritis. Adherence factors, urease, and hemolysin may be virulence determinants. These factors were compared for bacteria cultured from 16 patients with acute pyelonephritis and 35 with
The gram-negative enteric bacterium Proteus mirabilis is a frequent cause of urinary tract infections in individuals with long-term indwelling catheters or with complicated urinary tracts (e.g., due to spinal cord injury or anatomic abnormality). P. mirabilis bacteriuria may lead to acute
OBJECTIVE
Proteus mirabilis is a common cause of urinary tract infection. We determined the role of Tamm-Horsfall protein as a host defense factor against the cystitis and pyelonephritis caused by P. mirabilis.
METHODS
We generated Tamm-Horsfall protein gene knockout mice using homologous
