Most UTIs are caused by Escherichia coli (E. coli) bacteria from the intestines that get into the urinary tract. To understand why some women get infection after infection and others get one or none, Hultgren teamed up with Broad Institute scientists Ashlee Earl, PhD, the senior group leader for the Bacterial Genomics Group at Broad and the
The researchers used different types of E.coli bacteria that were modified to produce bioluminescent light when under different stressful conditions: for example, one type glows if its DNA is
The main takeaway from these results, according to Mariana Byndloss, a microbiologist at Vanderbilt University Medical Center who peer reviewed the study, is “that commensal bacteria protect the host from pathogens by competing for nutrients.”. Byndloss adds that as the study used a synthetic community of microbes in a mouse model, “we Overview. Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals. Most types of E. coli are harmless or cause relatively brief diarrhea. But a few strains, such as E. coli O157:H7, can cause severe stomach cramps, bloody diarrhea and vomiting. E. coli O157. Common sources: Cattle farms, where E. coli O157 can live in the intestines of healthy cattle; less commonly, poop from an infected person or animal that gets into the water through sewage overflows, sewage systems that are not working properly, polluted storm water runoff, or agricultural runoff
