When was Proteus mirabilis discovered?
Proteus was first discovered by Gustav Hauser [Figure 1], a German pathologist, in 1885. [1] Accounting for more than 90% of proteus infections, Proteus mirabilis is a highly motile Gram-negative bacterium.
Where is Proteus mirabilis found in nature?
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.
When was the UTI discovered?
Urinary tract infections have been described since ancient times with the first documented description in the Ebers Papyrus dated to c. 1550 BC.
What is Proteus mirabilis known for?
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.
How did I get Proteus mirabilis?
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.
How did I get Proteus mirabilis in my urine?
mirabilis occur usually in patients under long-term catheterization. The bacteria have been found to move and create encrustations on the urinary catheters. Proteus mirabilis can enter the bloodstream through wounds. This happens with contact between the wound and an infected surface.
How were UTIs cured before antibiotics?
19th Century: In addition to bed rest, healthy dieting, plasters, narcotics, and herbal enemas and douches, physicians began using bleeding with cupping and leeches to treat infections. Scientists eventually discovered that UTIs were caused by microorganisms, which led to deeper investigation into treatment options.
What color is Proteus?

Why does my pus smell sweet?
Gram-negative and anaerobic bacteria can create foul odors due to tissue breakdown. Many bacteria have a distinct odor such as the sweet odor that characterizes Pseudomonas or the ammonia-like odor of Proteus.
What is the historical significance of Proteus mirabilis?
Description and significance. Proteus mirabilis was first discovered by a German pathologist named Gustav Hauser (Williams and Schwarzhoff, 1978). Hauser named this genus Proteus, after the character in Homer’s The Odyssey that was good at changing shape and evading being questioned (Williams and Schwarzhoff, 1978),…
Is Proteus mirabilis Gram positive or negative?
Proteus mirabilisis 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.
How does progressiveproteus mirabilis get into the urinary tract?
Proteus mirabilis often gets into the urinary tract via a urinary catheter. Sometimes, patients require a urinary catheter in order to control the excretion of urine, like Nancy.
What is the treatment for Proteus mirabilis?
Proteus Mirabilis Treatment. Since Proteus mirabilis is a form of bacteria, infections caused by Proteus mirabilis are usually treated using antibiotics. Antibiotics are used to kill bacteria in the body.
