What's a GeneRIF?
  1. These results show that the treA gene is needed for optimal production of type 1 fimbriae in extraintestinal pathogenic Escherichia coli strain MT78 and that loss of treA significantly reduces its cell invasion capacity and colonization of the bladder in a murine model of urinary tract infection.
