Quick Answer: What Antibiotics Treat Proteus?

Where does Proteus come from?

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 Antibiotics kill Proteus mirabilis?

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.

Does amoxicillin cover Proteus?

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.

How do you get Proteus infection?

Infection occurs either by migration of bacteria up the catheter along the mucosal sheath or by migration up the catheter lumen from infected urine. UTIs are the most common clinical manifestation of Proteus infections.

How do you treat Proteus UTI?

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 is a Proteus infection?

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.

What is Proteus 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.

Can Proteus mirabilis be sexually transmitted?

Each day of catherization gives an infection rate of 3-5%. Urinary tract infections caused by P. mirabilis also occur commonly in sexually active women and men, especially those engaging in unprotected intercourse.

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.

What are the symptoms of Proteus infection?

Proteus mirabilis commonly causes urinary tract infections and the formation of stones….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)

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.

Is Proteus sensitive to amoxicillin?

Most types of antibiotics are sensitive to P. mirabilis such as penicillin’s, cephalosporins, aminoglycosides, refamycin, fluoroquinolones, and phenicols while resistant to amoxicillin, cefotaxime and carbenicillin [8,9].
