Proteus mirabilis is a gram-negative facultative anaerobe with swarming motility and an ability to self-elongate and secrete a polysaccharide which allows it to attach to and move along surfaces like catheters, intravenous lines, and other medical equipment. The complications of Proteus pneumonia include associated bacteremia with metastatic foci, particularly meningitis. 20-45% of UTIs in chronically catheterized patients, often associated with biofilm formation. Proteus mirabilis is the most frequent pathogen, causing 1%-2% of all UTIs and 1%-3% of all bloodstream infections.1-4 Spondylodiscitis and septic emboli are rarely reported complications of infection by Proteus species.5 P. mirabilis biofilms formed on foreign materials such as urinary and central venous catheters allow Proteus mirabilis is a type of bacteria that can cause infections in the body, particularly urinary tract infections. Escherichia coli were the predominant pathogen isolated from the urine specimen followed by Proteus mirabilis, Pseudomonas aeruginosa and Enterobacter aerogenes. In addition, P. vulgaris and P. hauseri are sensitive to ceftazidime, ceftriaxone, imipenem, ciprofloxacin, netilmicin, sulbactam, meropenem, and levofloxacin. 15th ed.

UPEC infections account for roughly 80% of all UTIs, causing cystitis in the bladder and acute pyelonephritis in the kidneys. [Medline]. d. it limits phagocytosis of the organism. Fifty samples were collected and processed. A rare but severe health complication caused by untreated UTI is permanent kidney damage or infection of the kidneys (pyelonephritis). Invasion occurs through the actions of Ibe proteins, FimH, OmpA and cytotoxic necrotizing factor 1 (CNF1).28 The K1 capsule – which is found in approximately 80% of NMEC isolates – also has a role in invasion by preventing lysosomal fusion and thus allowing delivery of live bacteria across the blood–brain barrier.66 In the central nervous system the bacterium can induce edema, inflammation and neural damage. a. it is the chief virulence factor of Group A streptococci.

Most Proteus strains are lactose-negative and . Overgrowth becomes apparent between the ages of 6 and 18 months and becomes more severe with age. The enzyme hydrolyzes urea to CO2 and NH3, which initiates struvite or apatite stone formation. Although E. coli causes 86% of UTIs, other pathogens, such as Klebsiella species, Proteus species, and Staphylococcus saprophyticus, may also cause these infections. Proteus mirabilis is commonly the causative agent of complicated urinary tract infections (UTIs), UTIs associated with components that compromises the urinary tract or host defense, especially in individuals with functional or structural abnormalities or with long-term catheterization for patients whose bladders will not empty fully or empty at inappropriate times.

Virulence factors of P. mirabilis. When Proteus infection occurs together with other microbes, infant diarrhea is more severe. This raises the pH of the urine and facilitates the . A number of specific proteins encoded by chromosomal genes have been implicated as virulence factors that allow P. mirabilis to colonize its host, evade host defenses, and cause damage to the host (Figure 3).The production of one of these proteins, urease, is a hallmark of Proteus infection. Like Proteus species, Morganella morganii has properties that enhance its ability to infect the urinary tract; these include motility and the ability to produce urease.

It is commonly associated with pulmonary tuberculosis, Actinomyces, and nontuberculous organisms like Staphylococcus aureus. Mannose resistant, Proteus-like fimbriae are expressed in vivo, and although not essential for infection, they appear to play a significant role in the colonization of both bladder and kidney and their presence correlates with the development of acute pyelonephritis.
