Proteusvulgaris is a rod-shaped, gram-negative bacterium that occupies the intestinaltracts of animals and humans. In my Gram stain test the bacteriacontained rods on the shorter side, so I identified as bacteria to becococobaccilli.
Since the presence of flagella exist, species included in thisgenus are motile and most strains flock in periodic cycles and yield a spreadof uniform film over the nutrient media which was evident in my streak plate. It’s an opportunistic pathogen which can cause urinarytract infections, pneumonia, or septicemia. Outside intestinal tracts of humansand animals, Proteus vulgaris can also be found in soil, contaminated water.
Greatestshared complications related to P. vulgaris are due to patients with asuppressed immune system and is most frequently found in people withimmunodeficiency disease and is also mutual common in patients who need acatheter. While Proteus vulgaris can be pathogenic, it is also part of theintestinal normal flora. Gram negative bacteria regularly colonize both skinand oral mucosa of both patients and hospital employees. So that why diseasescaused by P. vulgaris are generally found in hospitals.
P. vulgaris is the leadpathogen that causes hospital born Proteus diseases. As stated before, iscommonly found in the urinary tract. This is because the urinary tract is ahospital environment for this species of Proteus.
This is caused by the microbes’ability to degrade urea to ammonia with the enzyme ureaseExpandingon the extremely motile of the microbe P. mirabilis its flagella allow themotile microbe can be seen as a wave like look on a petri dish due to growingand stopping on plated colonies. The flagellum of P. mirabilis is vital to itsmotility a characteristics that help the organism inhabit. P.
mirabilis alsorelies on its pili of adhesion to escape being flushed out of the urinary tractsystem. Proteus mirabilis ureas has a very importance to the accountable forraising the pH and consequently making is easier to thrive and increase pHallows stone formation to take place. On occurrence the stones fill the entirerenal pelvis. Likewise present are endotoxins, responsible for induction of theinflammatory reaction system and pore-forming hemolysis. .
The flagellum has alsobeen connected to the ability of P. mirabilis to form biofilms, helping to the bacteria’sresistance to defenses of the host and select antibiotics.The P.vulgaris species is unfortunately not susceptible to ampicillins or cephalosporinlike other Proteus species are though. On the other hand, P. vulgaris issusceptible to Ampicillin, streptomycin, and chloramphenicol. Fluids are alsorecommended as a defense from this.
