Engineered probiotic bacteria provide accurate 3D images of tumors in mice, reports study published in the journal PLoS ONE.

According to the authors, led by Mark Tangney of University College Cork in Ireland, "before now, researchers used luminescence to provide an approximation of where a test organism was within the body, and would then follow up with multiple further experiments using different techniques to try to find a precise location". This new research suggests that such bacteria can be engineered to contain diagnostic or therapeutic agents that would be produced specifically within the tumor for targeted treatment.
