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 get Proteus bacteria?
mirabilis occur usually in patients under long-term catheterization. The bacteria have been found to move and create encrustations on the urinary catheters. Proteus mirabilis can enter the bloodstream through wounds. This happens with contact between the wound and an infected surface.
Where does Proteus come from?
Proteus bacilli are widely distributed in nature as saprophytes, being found in decomposing animal matter, sewage, manure soil, the mammalian intestine, and human and animal feces. They are opportunistic pathogens, commonly responsible for urinary and septic infections, often nosocomial.
How do I know if I have Proteus mirabilis?
Diagnosis. An alkaline urine sample is a possible sign of P. mirabilis. It can be diagnosed in the lab due to characteristic swarming motility, and inability to metabolize lactose (on a MacConkey agar plate, for example).
How do you get Proteus mirabilis in your urine?
It is thought that the majority of P. mirabilis urinary tract infections (UTI) result from ascension of bacteria from the gastrointestinal tract while others are due to person-to-person transmission, particularly in healthcare settings (1).
How do I get rid of Proteus bacteria?
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.
What kills Proteus mirabilis?
Polymyxin B is bactericidal in vitro against Gram-negative bacteria including Proteus mirabilis, P. aeruginosa, and Serratia marcescens. In vitro activity has also been demonstrated against Acinetobacter baumannii, a multidrug-resistant Gram-negative organism associated with wound infections leading to septicemia.
How does Proteus cause UTI?
Proteus species also produce urease, which has been shown to be associated with an increased risk of pyelonephritis and upper UTIs. Proteus species also hydrolyze urea to ammonia, thereby alkalinizing the urine. Through the production of urease and ammonia, Proteus can produce an environment where it can survive.
What is the best antibiotic to treat 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 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.
What is the most common way that Proteus mirabilis gets into the urinary tract?
To reach the urinary tract, P. mirabilis uses swarming motility to migrate across the catheter surface. This unique type of motility also facilitates migration of non-motile species colonizing the catheter.
Can Proteus cause pneumonia?
The mortality rate in these cases, however, has been high. The only other reported cases of pulmonary involvement due to Proteus organisms have been 2 cases of pleurisy and 1 case of multiple pulmonary abscesses, all of which were fatal. No previous report of pneumonia due to a Proteus organism could be found.
What antibiotic is Proteus mirabilis sensitive to?
P mirabilis is likely to be sensitive to ampicillin; broad-spectrum penicillins (eg, ticarcillin, piperacillin); first-, second-, and third-generation cephalosporins; imipenem; and aztreonam. P vulgaris and P penneri are resistant to ampicillin and first-generation cephalosporins.
What does Proteus mirabilis cause?
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. mirabilis UTI have not been determined.
What bacteria causes UTI?
A UTI occurs when bacteria from another source, such as the nearby anus, gets into the urethra. The most common bacteria found to cause UTIs is Escherichia coli (E. coli).
Does amoxicillin treat Proteus mirabilis?
Amoxicillin was used in the treatment of 36 infections in 35 patients with adequate gmnulocyte counts. The antibiotic was effective against 61 % of all infections, against 90% of infections caused by gram-positive organisms, and against 77% of infections caused by Escherichia coli, and Proteus mirabilis.
