Understanding the Proteus species and how it infects your urinary tract or vagina Pus in the urine (cloudy urine, pyuria).Symptoms of Proteus urinary tract infection In men, having unprotected anal or vaginal sex and not being circumcised increase UTI risk. Women who are sexually active have a greater risk of UTIs. In babies, boys see more Proteus infections than girls due to more anatomical abnormalities found in boys than girls.Īfter age 50, the balance of infection between genders evens out, however, UTIs overall are most common in people aged between 20 and 50, particularly women. In those who are catheterised or have what’s known as a ‘complicated UTI’, the incidence is 20-45 per cent. Urinary tract infections are the most common clinical manifestation, with Proteus being responsible for 1-2 per cent of UTIs in healthy women and about five per cent of hospital-acquired UTI. The Proteus infection occurs due to the migration of bacteria up the catheter or by migration up the catheter from infected urine.
Proteus infection rates are increased in women, those with long catheterisations, anyone with an underlying illness, faulty catheter insertions, and lack of antibiotic therapy. People with indwelling catheters are at an increased risk of Proteus infection of 3-5 per cent per day of catheterisation. People suffering recurrent infections are most at risk, along with those with structural abnormalities of the urinary tract, those who have had instruments inserted into the urethra, and those with a hospital-acquired infection. Proteus species that can cause urinary tract infections (UTIs): Proteus species can be antibiotic-resistant, and therefore susceptibility testing should be conducted on fluid samples prior to offering antibiotic treatment. Some Proteus species are able to develop biofilms, a protective coating on cells that defends the microbes from treatments. Proteus organisms are believed to be responsible for serious infections in humans, being most commonly found in the digestive tract, but also in the urinary tract.Īnyone can become infected with Proteus species in the urinary tract or vagina, but some groups are more at risk than others.
