It is not susceptible to nitrofurantoin or tetracycline and has experienced increasing drug resistance of ampicillin, trimethoprim, and ciprofloxin. Treatment and Prevention: Proteus mirabilis infections can be treated with broad-spectrum penicillins or cephalosporins except in severe cases. Then, an oral quinolone, cephalosporin, or TMP/SMZ for 14 days may be added to complete treatment.
A positive result is a red color in the liquid, and a negative result would be a yellowish color.įor hospitalized patients, therapy consists of parenteral (or oral once the oral route is available) ceftriaxone, quinolone, gentamicin (plus ampicillin), or aztreonam until defervescence. The methyl Red test was used to show which bacterium would be able to produce a mixture of acids that would ferment glucose. The specific mode of transmission, however, has not been identified. They may also be transmitted through contaminated catheters (particularly urinary catheters) 1, 4, 5 or by accidental parenteral inoculation. In recent years, the resistances to many antibiotic classes (also beta-lactams) has significantly increased. It causes urinary tract and wound infections. Proteus vulgaris is an aerobic, rod-shaped, Gram-negative bacterium in the Enterobacteriaceae family. Vulgaris, previously considered biogroup 2, has been reported to cause UTIs, wound infections, burn infections, bloodstream infections, and respiratory tract infections (71, 137).
