Probiotic Bacteria Effectively Target Tumors in Mice

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

The specially engineered probiotic bacteria, like those found in many yoghurts, were intravenously injected into mice with tumors, after which the researchers took full body bioluminescent images. The 3D images revealed information about the number and location of the bacteria, to the level of precisely revealing where within the tumour the bacteria were living, providing much more information on the interaction of bacteria and tumors than was previously available using similar two-dimensional imaging methods.
