Proteus mirabilis is a Gram-negative bacterium which 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.
How do you get Proteus infection?
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.
Is 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 are the symptoms of Proteus infection?
Proteus can cause gastroenteritis, urinary tract infections, and wound infections. The ingestion of food contaminated by Proteus may contribute to the sporadic and epidemic cases of gastroenteritis, which may cause symptoms such as vomiting, fever, abdominal pain, severe nausea, diarrhea, and dehydration.How is Proteus infection treated?
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?
Proteus Mirabilis Treatment Since Proteus mirabilis is a form of bacteria, infections caused by Proteus mirabilis are usually treated using antibiotics. Antibiotics are used to kill bacteria in the body.
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.
How did I get Proteus mirabilis in my 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).Can Proteus cause pneumonia?
The bacteria induce an inflammatory response that can cause sepsis and systemic inflammatory response syndrome (SIRS). P. mirabilis can also, though less common, colonize the lungs. This is the result of infected hospital breathing equipment and causes pneumonia.
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.
Article first time published onDoes 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.
What does Proteus in urine mean?
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.
Does Proteus mirabilis cause kidney stones?
Summary: Scientists now have inside information to use in the fight against Proteus mirabilis — a nasty bacterium that can cause kidney stones, as well as hard-to-treat urinary tract infections.
Is Proteus sensitive to amoxicillin?
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 antibiotic kills Proteus vulgaris?
mirabilis. The tested antibiotics included: ciprofloxacin, ceftriaxone, nitrofurantoin, and gentamicin. Of them, ciprofloxacin showed the highest activity. Up to 93% reduction in biofilm formation was achieved using a concentration of ciprofloxacin corresponding to 1/2MIC.
How long does Proteus mirabilis live on surfaces?
survive only for a few days on inanimate surfaces; and only 1 to 2 days in the case of P. vulgaris 9 . They also survive well within the environment in soil, water, and sewage 3 .
Does Cipro treat Proteus mirabilis?
CIPRO is indicated in adult patients for treatment of lower respiratory tract infections caused by Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Proteus mirabilis, Pseudomonas aeruginosa, Haemophilus influenzae, Haemophilus parainfluenzae, or Streptococcus pneumoniae.
Does cranberry juice help a urinary infection?
Cranberry juice and cranberry juice supplements are perhaps the most popular natural treatments for UTIs. Cranberries contain compounds such as phenolic acids and flavonoids, which may help treat and prevent UTIs.
Can Proteus cause sepsis?
Because Proteus and Pseudomonas organisms are gram-negative bacilli, they can cause gram-negative endotoxin-induced sepsis, resulting in systemic inflammatory response syndrome (SIRS), which carries a mortality rate of 20%-50%.
Is cranberry good for infections?
Topic Overview. For years, people have used cranberry juice to prevent and help cure urinary tract infections (UTIs). There is limited proof that this is worth trying. Pure cranberry juice, cranberry extract, or cranberry supplements may help prevent repeated UTIs in women, but the benefit is small.
How can Proteus vulgaris be prevented?
Proteus is more common in people who have or have had a urinary catheter. Minimizing the incidence and duration of urinary catheterization is an important part of preventing infection.
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).
What color is Proteus?

Is Proteus good or bad?
Proteus spp. are regarded to be an undesired element of intestinal microflora, as the bacteria may also become a causative agent of diarrhea.
What bacteria smells like popcorn?
Proteus bacteria, known for their “sweet, corn tortilla smell” (?!), may be responsible for the popcorn scent of your dog’s feet.
Is Proteus mirabilis resistant to penicillin?
P. mirabilis and P. penneri were naturally resistant to penicillin G, oxacillin, all tested macrolides, lincosamides, streptogramins, glycopeptides, rifampicin and fusidic acid.
Does bactrim treat Proteus mirabilis?
BACTRIM is indicated in the treatment of severe or complicated urinary tract infections in adults and pediatric patients two months of age and older due to susceptible strains of Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis and Proteus vulgaris when oral …
Does Keflex treat Proteus mirabilis?
KEFLEX is indicated for the treatment of genitourinary tract infections, including acute prostatitis, caused by susceptible isolates of Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae.
What is a complicated UTI?
Complicated urinary tract infections (UTIs) occur in the setting of pre-existing metabolic, functional, or structural abnormalities of the urinary tract. They may involve both lower and upper tracts. Complicated UTIs may significantly increase the rate of therapy failures and cause damage that leads to recurrence.
Is Proteus mirabilis in stool?
mirabilis was identified in 2.7% of healthy subjects, which is a probable underestimate as the epithelial preference of P. mirabilis means that it is likely undersampled in stool specimens (92). Proteus penneri and P. vulgaris were isolated from 0.9% and 4.2%, respectively, of the same population (92).
What happens if UTI goes untreated?
The main danger associated with untreated UTIs is that the infection may spread from the bladder to one or both kidneys. When bacteria attack the kidneys, they can cause damage that will permanently reduce kidney function. In people who already have kidney problems, this can raise the risk of kidney failure.
