Bacteria study of male adolescents reveals new insights into urinary tract health

Image
The first study using cultivation independent sequencing of the microorganisms in the adolescent male urinary tract has revealed that the composition of microbial communities colonizing the penis in young men depends upon their circumcision status and patterns of sexual activity.

This study, published Friday in the online journal PLoS One, is the first by Indiana University researchers working with a four-year, $7 million grant from the National Institutes of Health's Human Microbiome Project. It is also the first to reveal that urogenital bacterial communities of young men are surprisingly stable and that some of these bacteria are similar to species that colonize and protect healthy young women from sexually transmitted infections.

The research contradicts the accepted wisdom that pre-sexual men did not have bacteria in their urinary tracts.
