How is Proteus vulgaris transmitted?

MODE OF TRANSMISSION: Proteus spp. are part of the human intestinal flora 1 3- 5 and can cause infection upon leaving this location. They may also be transmitted through contaminated catheters (particularly urinary catheters) 1 4 5 or by accidental parenteral inoculation.

Where is Proteus vulgaris usually found?

Proteus vulgaris is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter.

Does Proteus vulgaris cause meningitis?

Since 1952 there has been no reported case of Proteus meningitis in the neonatal period. Proteus mirabilis is thought to be a fairly common inhabitant of the gastrointestinal tract; yet in a review of the literature it was found that there has never been reported a case of meningitis due to this organism.

What causes 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.

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 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 difference between Proteus mirabilis and Proteus vulgaris?

Proteus mirabilis (indole negative) is the most frequent Proteus species associated with urinary tract infections, but indole-positive Proteus species like Pr. vulgaris, which are more often resistant to ampicillin, may also cause urinary tract infections. These species are often associated with an alkaline urine.

Why is Proteus vulgaris important?

Proteus vulgaris Proteus vulgaris is an facultative anaerobe, rod-shaped, Gram-negative bacterium in the Enterobacteriaceae family. It causes urinary tract and wound infections. In recent years, the resistances to many antibiotic classes (also beta-lactams) has significantly increased.

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.

Is Proteus vulgaris a coliform?

The genera Escherichia, Klebsiella, Enterobacter, Serratia, and Citrobacter (collectively called the coliform bacilli) and Proteus include overt and opportunistic pathogens responsible for a wide range of infections. Many species are members of the normal intestinal flora.

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 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.

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%.

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.

What is the most common way that Proteus mirabilis gets into the urinary tract?

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). This is supported by evidence that some patients with P.

What is Enterococcus faecalis in urinary tract infection?

Enterococcus faecalis is a gram-positive bacterium that can cause a variety of nosocomial infections of which urinary tract infections are the most common. These infections can be exceptionally difficult to treat because of drug resistance of many E.

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 happens if cystitis is left untreated?

An untreated bladder infection can lead to kidney infection, also called pyelonephritis (pie-uh-low-nuh-FRY-tis). Kidney infections may permanently damage your kidneys.

Are Proteus vulgaris motile?

Proteus is a gram-negative, anaerobic bacterium of the Enterobacteriaceae family (Brooker 2008). Under the microscope it is rod shaped, motile (can move due to its flagella) and has a characteristic “swarming” ability that allows it to migrate across catheter surfaces (Armbruster 2013).

Does Proteus vulgaris have a cell wall?
