What does P. vulgaris cause?
P. vulgaris, previously considered biogroup 2, has been reported to cause UTIs, wound infections, burn infections, bloodstream infections, and respiratory tract infections (71, 137).
How is P. 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.
How is Proteus vulgaris 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.
Where can P. vulgaris be 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.

How common is Proteus infection?
Proteus infection accounts for 1%-2% of UTIs in healthy women and 5% of hospital-acquired UTIs. Complicated UTIs (ie, those associated with catheterization) have a prevalence of 20%-45%. UTIs are more common in males then females in the neonatal population.
How does Proteus vulgaris affect humans?
It is grouped with the Morganellaceae and is an opportunistic pathogen of humans. It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. P. vulgaris was one of the three species Hauser isolated from putrefied meat and identified (1885).
What causes Proteus bacteria in urine?
It is thought that the majority of Proteus mirabilis UTI (urinary tract infections) result from ascension of bacteria from the gastrointestinal tract while others are due to person-to-person transmission, particularly in healthcare settings 12).
Is Proteus hauseri motile?
Proteus hauseri Known as: Proteus genomosp. 3, Proteus genomospecies 3, Proteus vulgaris biogroup 3 A species of facultatively anaerobic, Gram-negative, rod shaped bacteria assigned to the phylum Proteobacteria. This species is motile, indole…
What are the clinical manifestations of Proteus hauseri infection?
P. hauseri, previously considered biogroup 3, has not been associated with infections in humans. The clinical manifestations of infections with Proteus spp. are, in the main, non-specific. However, urinary tract infections involving struvite stones are characteristic.
How many colonial variants of Proteus hauseri are there?
SUMMARY: Cultures of Proteus hauseri may consist of one or more of five colonial variants. Population pressure experiments… Expand
Is Proteus bacilli a virulence factor?
[Proteus bacilli: features and virulence factors] In this article, different aspects of virulence factors of Proteus bacilii (P. mirabilis, P. vulgaris, P. penneri i P. hauseri) are presented. These are opportunistic pathogens that cause different kinds of infections, most frequently of the urinary tract.
