Dear Editor,

Urinary tract infections (UTI) are as bacterial infections, affecting millions of people every year worldwide. Prevotella corporis (P. corporis) and P. Copri are belongs to Prevotella genus as Gram-negative, anaerobic bacilli. P. corporis is present in the mouth and other sites of the human body.[1],[2],[3]P. Copri is present in human gut and has been isolated from rheumatoid arthritis.[4],[5] It has to be said that there are many bacteria that are involved in UTI diseases either directly or indirectly.[6],[7],[8] Possibly there are many bacteria which are not identified at the present time, and maybe introduced in the future possibly P. corporis and P. copri are linked to UTI disease. Researches must be done in order to understand the fact. Why till now these bacteria has not been isolated from UT may be related to many reason such as, new introducing these bacteria in recent years, nonavailability of specific tests in order to the identification of the microorganism, and perhaps they are unknown yet for many microbiologists across the World. There are different question around the question raised above. The best question is may P. corporis and P. copri linked to UTI or not? If yes what causes infection in the UT? Whether the infection is caused by P. corporis alone or with P. copri or even with other bacteria which are present in the UT. The further studies may hopefully clear different aspects of these black-pigmented bacteria in UTI. If the future studies by scientists and researchers are negative, that would be good news for all in particular for patients. In this Letter to the Editor, I would like to bring to your attention the point that I have mentioned in the past, that the role of P. corporis is not clear in oral diseases and in particular in nonoral diseases (i.e., UTI).[9] Still, the question remains about where it comes from into the mouth, gut actually? What causes infection in the gut? Which infections is caused by P. corporis alone or P. copri or even with other bacteria. Anyway, the role of P. corporis and P. copri still unclear in UT. Thus, we have to look forward to see what is going on these unknown bacteria (P. corporis, P. copri) and their possible link in UTI anyway.
