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 symptoms does Proteus vulgaris cause?
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 .
Is Proteus vulgaris contagious?
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.
Is Proteus vulgaris normal in the gut?
Proteus species, members of the Enterobacteriaceae family, are usually considered commensals in the gut and are most commonly recognized clinically as a cause of urinary tract infections.
Is Proteus vulgaris harmful?
P. vulgaris, previously considered biogroup 2, has been reported to cause UTIs, wound infections , burn infections, bloodstream infections, and respiratory tract infections (71, 137).
What is the treatment for Proteus vulgaris?
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.
How do you get Proteus bacteria?
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 .
How do you identify Proteus vulgaris?
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.
Where is Proteus vulgaris normally found?
Proteus mirabilis and Proteus vulgaris are commensals of the normal flora of the human gastrointestinal tract , but they also can be found in water and soil. There are opportunistic pathogens that can infect the lungs, or wounds, and frequently cause urinary tract infections.
Is Proteus vulgaris a gram-negative bacteria?
Proteus species are part of the Enterobacteriaceae family of gram-negative bacilli . The first isolates were reported and characterized by Hauser in the late 19th century. The genus is currently composed of Proteus mirabilis, Proteus vulgaris, Proteus penneri, Proteus hauseri, Proteus terrae, and Proteus cibarius.
What is the significance of Proteus vulgaris?
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.
What color is Proteus vulgaris?
| Susceptibility Testing Text: Potassium cyanide : – | Aerobic Growth Tests Text: Urea hydrolysis : + | Temperature For Growth Text: at 37°C : Yes | Colony Appearance Text: smooth : Yes,shiny : Yes | Colony Color Text: cream : Yes |
|---|
Can Proteus be found in stool?
Rare occurrence of Proteus vulgaris in faeces: a reason for its rare association with urinary tract infections.
Does P vulgaris ferment sucrose?
P. vulgaris fermented glucose , sucrose, and maltose readily, while P. mirabilis fermented glucose readily and sucrose slowly and did not ferment maltose.
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.
