Abstract

Gut commensals profoundly affect host immunity and intestinal homeostasis, but the impact of commensal eukaryotic protozoans is poorly understood. In a recent Cell paper, Chudnovskiy et al. (2016) identify a commensal protozoan, Tritrichomonas musculis, that can enhance anti-bacterial defenses, but at the cost of increasing intestinal inflammation.
