Proteus mirabilis urease, a nickel-containing enzyme, has been established as a critical virulence determinant in urinary tract infection. An amino acid sequence (residues 308 to 327: TVDEHLDMLMVCHHLDPSIP) within the large urease subunit, UreC, is highly conserved for every urease examined thus far and has been suggested to reside within the enzyme active site Abstract. Proteus mirabilis, a Gram-negative bacterium, commonly causes catheter-associated urinary tract infections, wound infections, gastroenteritis and, in some cases, bacteremia.The phenotypic hallmarks of this bacterium include swarming motility, urease and hemolysin production, and synthesis of numerous adherence fimbriae Proteus mirabilis is the third most common cause of nosocomial infections accounting for 90% of all Proteus infections . A major problem in wound infections is the ever-rising antimicrobial resistance in P. mirabilis (12-14). Proteus mirabilis may become resistant to β-lactams upon the acquisition of heterologous β-lactamase genes Proteus spp abundance was assessed by ure gene-specific polymerase chain in 54 pairs of fecal samples and 101 intestinal biopsies from patients with CD and healthy controls. The adherence, invasion, and intracellular presence of 2 distinct isolates of Proteus mirabilis in epithelial cells were evaluated using immunofluorescence and electron microscopy Proteus mirabilis, a gram-negative enteric bacterium, occurs as vegetative swimmer cells and hyperflagellated swarmer cells (6). Individuals suffering from urinary tract infections (UTI) caused by P. mirabilis often develop bacteriuria, kidney and bladder stones, catheter obstruction due to stone encrustation, acute pyelonephritis, and fever.

Proteus mi. rabilis (P. mirabilis) is a species of Gram-negative and facultative anaerobic bacteria that shows swarming motility and urease activity.

Proteus mirabilis UTI. Proteus mirabilis is a Gram-negative, facultative anaerobe bacilli, part of the Enterobacteriaceae family, with an ability to ferment maltose and inability to ferment lactose 1).Proteus mirabilis is well-known in clinical laboratories and microbiology survey courses as the species that swarms across agar surfaces, overtaking any other species present in the process Proteus mirabilis compromises the care of many patients undergoing long-term indwelling bladder catheterization. It forms crystalline bacterial biofilms in catheters which block the flow of urine, causing either incontinence due to leakage or painful distention of the bladder due to urinary retention. If it is not dealt with, catheter blockage can lead to pyelonephritis and septicemia Proteeae Proteus P. Vulgaris P. Mirabilis P. Penneri P.

An intracranial abscess caused by Proteus mirabilis is rarely reported in adults. A 17-year-old girl presented with generalized tonic-clonic seizure, high-grade fever, headache, and vomiting with a history of slowly progressing apathy, clumsiness, and disorientation. She had meningeal signs and altered sensorium with a Glasgow Coma Scale of 10 Proteus mirabilis is a Gram negative bacterium that is a frequent cause of catheter-associated urinary tract infections (CAUTIs). Its ability to cause such infections is mostly related to the formation of biofilms on catheter surfaces. In order to form biofilms, P. mirabilis expresses a number of virulence factors. Such factors may include adhesion proteins, quorum sensing molecules. P. mirabilis is susceptible to most common disinfectants used in animal facilities. Any chemical or mechanical sterilant will also serve to remove P. mirabilis from the environment. Many human isolates of P. mirabilis are susceptible to the fluoroquinones (enrofloxacin is a common one in veterinary use) or trimethoprim/sulfa drugs Proteus mirabilis is a common cause of catheter-associated urinary tract infection (CAUTI) and secondary bacteremia, which are frequently polymicrobial. We previously utilized transposon insertion-site sequencing (Tn-Seq) to identify novel fitness factors for colonization of the catheterized urinary tract during single-species and polymicrobial infection, revealing numerous metabolic pathways. 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 hemolysin and urease to elicit tissue damage that allows entry of these bacteria into the kidney

Introduction. Among the most common community-acquired and nosocomial infections are those of the urinary tract (Kahlmeter, 2000; Johansen et al., 2006).After Escherichia coli, Proteus mirabilis is the most frequent etiological agent, especially in patients with urinary catheters or with structural abnormalities of the urinary tract (Warren et al., 1982; Mobley & Belas, 1995) A bacteriophage typing scheme for differentiating Proteus isolated from clinical specimenswasdeveloped. Twenty-onedistinctpatternsoflysis wereseen when 15 bacteriophages isolated on 8 Proteus mirabilis, 1 P. vulgaris, and 1 P. morganii were used to type 162 of 189 (85.7%) P. mirabilis and P. vulgaris isolates Proteus mirabilis in vitro Biofilms Proteus has been shown to produce biofilms in diverse environ-ments from aquatic conditions6 to indwelling devices [vascular access ports/hemasites, scleral buckles, ureteral stents, urethral catheters and tracheesophageal voice prostheses (Provox2)].7-11 P. mirabilis can produce biofilms on nonliving. Proteus mirabilis is frequently found in soil and wastewater, because it decomposes organic matter.

Proteus are a natural part of the intestinal flora of healthy individuals. In addition, they are found as rot pathogens in soil and water. The diseases caused by them are mostly urinary tract infections, rare systemic infections such as sepsis, endocarditis or meningitis. Proteus mirabilis isolated far more common than Proteus vulgaris The crystalline biofilms of Proteus mirabilis can seriously complicate the care of patients undergoing long-term indwelling urinary catheterisation. Expression of bacterial urease causes a significant increase in urinary pH, leading to the supersaturation and precipitation of struvite and apatite crystals. T Recent Open Access Article Proteus mirabilis is a Gram-negative bacterium and is well known for its ability to robustly swarm across surfaces in a striking bulls'-eye pattern. Clinically, this organism is most frequently a pathogen of the urinary tract, particularly in patients undergoing long-term catheterization. This review covers P. mirabilis with a focus on urinary tract infections (UTI), including disease models. Vitamin C has antimicrobial activity and is often used as an oral supplement accompanying antibiotic treatment in urinary tract infections (UTI). Proteus mirabilis is the third common species responsible for UTIs that are mostly treated with fluoroquinolones or aminoglycosides. Treatment of the UTI caused by P. mirabilis is problematic due to the ability to form biofilm on the urinary catheters Bacterial isolate.
