What are the symptoms of Proteus mirabilis?

Common symptoms include:

  • Frequency of urination.
  • Pyuria (presence of white blob cells in the urine)
  • Cystitis (bladder infection)
  • Back pain.
  • Urgency.
  • Hematuria (presence of red blood cells in the urine)

How do I get rid of Proteus mirabilis?

For hospitalized patients, therapy consists of parenteral (or oral once the oral route is available) ceftriaxone, quinolone, gentamicin (plus ampicillin), or aztreonam until defervescence. Then, an oral quinolone, cephalosporin, or TMP/SMZ for 14 days may be added to complete treatment.

How do you get infected with Proteus mirabilis?

How is Proteus mirabilis transmitted? The bacterium spreads mainly through contact with infected persons or contaminated objects and surfaces. The pathogens can also be ingested via the intestinal tract, for example, when it is present in contaminated food. The germs spread quickly because they are very agile.

How do you identify Proteus?

It is oxidase-negative but catalase- and nitrate-positive. Specific tests include positive urease (which is the fundamental test to differentiate Proteus from Salmonella) and phenylalanine deaminase tests. On the species level, indole is considered reliable, as it is positive for P.

What does Proteus mirabilis smell like?

Some characteristics of a Proteus culture are swarming and an ammonia smell. The Proteus habitat is widely distributed in the environment. As an opportunistic human pathogen, Proteus is found in the human and animal gastrointestinal tract, skin, and oral mucosa, as well as in feces, soil, water, and plant.

These infections can also cause bacteremia and progress to potentially life-threatening urosepsis. Additionally, P. mirabilis infections can cause the formation of urinary stones (urolithiasis).

Is a Proteus infection serious?

Proteus is found abundantly in soil and water, and although it is part of the normal human intestinal flora (along with Klebsiella species, and Escherichia coli), it has been known to cause serious infections in humans.

What is the best antibiotic for Proteus mirabilis?

The most appropriate treatment for P. mirabilis may be aminoglycosides, carbapenems (except imipenem), and 3rd generation cephalosporins. Recent P. mirabilis isolates were also mostly susceptible to augmentin, ampicillin-sulbactam, and piperacillin/tazobactam.

What does Proteus in urine mean?

Background/Purpose. Proteus mirabilis is a common pathogen responsible for complicated urinary tract infections (UTIs) that sometimes causes bacteremia. Most cases of P. mirabilis bacteremia originate from a UTI; however, the risk factors for bacteremia and mortality rates from P.
