Proteus is a genus of Gram-negative bacteria commonly linked to urinary tract infections (UTIs), especially in individuals with prolonged catheter use or weakened immune systems. They can also cause wound infections and, less frequently, respiratory infections. Proteus species are notable for their resistance to multiple antibiotics, which can make treatment more difficult.
Individuals showing symptoms of a UTI, such as burning during urination, frequent urination, or cloudy urine, would benefit from testing for Proteus, especially if they have recurrent infections or are immunocompromised. People with non-healing wounds or healthcare-associated infections, such as those in hospitals or long-term care facilities, may also need testing to identify Proteus as the causative agent.
Elevated levels of Proteus bacteria can cause a variety of symptoms, depending on the location of the infection. The most common symptoms are:
It is important to note that elevated Proteus levels do not always cause symptoms. In some cases, the bacteria may simply be present in the stool without causing any problems.
People can become infected with Proteus through contact with contaminated food, water, or soil, or through contact with the mucous membranes or wounds of an infected person.
Specifically, Proteus can be spread through the following routes:
There is some evidence to suggest that Proteus bacteria may play a role in the development of Crohn’s disease in some people. Proteus bacteria are opportunistic pathogens that can cause infections in a variety of body systems, including the digestive system. In some cases, Proteus bacteria have been found to be present in the intestines of people with Crohn’s disease.
