Concerning EAEC/UPEC strains involved in the Copenhagen UTI outbreak (genotype: aatA aggR aap aggA fyuA pic; phylogroup A) (Olesen et al., 2012), it was shown that the expression of AAF/I (gene aggA) allowed a pronounced increase of bacterial adherence to human bladder epithelial cells as well as it allowed biofilm formation at levels significantly higher than those of UPEC prototype strains (Boll et al., 2013). Here, ENSG00000279284 is linked to bacterial urinary tract infection.
