Consequently, prevention includes good sanitation and hygiene, including proper sterilization of medical equipment. SIRS has a mortality rate between 20 and 50 percent. One-hundred thousand cfus per milliliter in the urine are usually indicative of a urinary tract infection.
The bacteria have been found to move and create encrustations on the urinary catheters. It is not susceptible to nitrofurantoin or tetracycline and has experienced increasing drug resistance of ampicillin, trimethoprim, and ciprofloxin. Increased pH allows stone formation to take place.
The encrustations cause the catheter to block. Please help improve this section by adding citations to reliable sources. Indole -negative and nitrate reductase -positive no gas bubbles produced Methyl red -positive and Voges-Proskauer negative Can be both MR- and V-P-positive. Infections caused by P.
Urinary Proteus mirabilis unknown report infections caused by P. Diagnosis[ edit ] An alkaline urine sample is a possible sign of P. Symptoms for pneumonia include fever, chills, chest pain, rales, and cough.
It can produce hydrogen sulfide gas, and forms clear films on growth media. On occasion the stones fill the entire renal pelvis. Younger women are at greater risk than younger men; however, older men are at greater risk than older women due to the occurrence of prostate disease.
Pyelonephritis is marked by nausea and vomiting. Proteus mirabilis is part of the normal flora of the gastrointestinal tract, and as a result the bacteria enters the urinary tract or infects medical equipment by the fecal route. Prostatitis can occur as a result of P.
The most common infection involving Proteus mirabilis occurs when the bacteria moves to the urethra and urinary bladder. Unsourced material may be challenged and removed.
Although Proteus mirabilis mostly known to cause urinary tract infections, the majority of urinary tract infections are due to E.
The length of catherization is directly related to incidence of infection. When this organism, however, enters the urinary tract, wounds, or the lungs it can become pathogenic. It is a small gram-negative bacillus and a facultative anaerobe. Also present are endotoxins, responsible for induction of the inflammatory response system and pore-forming hemolysins.
Proteus mirabilis is part of the Enterobacteriaceae family. The flagellum of P. Disease[ edit ] This rod-shaped bacterium has the ability to produce high levels of ureasewhich hydrolyzes urea to ammonia NH3so makes the urine more alkaline.
Proteus species can also cause wound infections, sepsis, and pneumonia, mostly in hospitalized patients. Proteus mirabilis is characterized by its swarming motility, its ability to ferment maltose, and its inability to ferment lactose.
It is commonly found in the human digestive system. Cystitis bladder infection symptoms are easier to distinguish and include back pain, concentrated appearance, urgency, hematuria presence of red blood cells in the urineand suprapubic pain as well as increased frequency of urination and pyuria.
It can also be found free living in water and soil. This line is named the Dienes line after its discoverer Louis Dienes. The bacteria can be found throughout the stones, and these bacteria lurking in the kidney stones can reinitiate infection after antibiotic treatment.
Important to Proteus mirabilis is urease, responsible for raising the pH and consequently making it easier to thrive. Pyelonephritis kidney infection can occur when the bacteria migrates from the lower urinary tract. Proteus mirabilis is part of the normal flora of the human gastrointestinal tract.Identification of Proteus vulgaris from an Unknown Sample.
Praise Selah G. Dagoc Mambajao, Camiguin Abstract Identification of microorganisms from unknown sample is a routine work for a Registered Medical Technologist assigned.
Proteus mirabilis is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. It shows swarming motility and urease activity. P. mirabilis causes 90% of all Proteus infections in humans. It is widely distributed in soil and water. Diagnosis. An alkaline urine sample is a possible sign.

UNKNOWN LAB REPORT Report by TABITHA MATTHEWS MICROBIOLOGY FALL INTRODUCTION The discipline of microbiology has many applications in science and medicine. This unknown laboratory study was an exercise. The unknown had a positive result for H2S production, and as such, eliminated Proteus myxofaciens from the possible identities of the unknown, thus bringing down the possible identity of the unknown organism into one: Proteus mirabilis.
The goal of this report is to identify two unknown bacteria using a series of tests while eliminating unlikely choices. One test tube has been provided with a mixture a Gram positive and a Gram negative bacteria. Gram negative unknown is Proteus vulgaris.
