“…We excluded subjects with any medical history of urinary tract corrective surgery or abnormality, bladder catheterization, or hospitalization in the 6 months before the fecal sample collection. As part of a separate study (Rubin, Mussio, Xu, Suh, & Riley, 2020), participants were given a pre‐addressed kit containing a rectal swab in Cary‐Blair transport media (Becton Dickinson BBLTM), two biosafety bags, detailed collection instructions, and a questionnaire asking about age, gender, recent antibiotic use, history of UTI, and lifestyle characteristics.
