Study Endpoints
Primary Endpoints
Number of Participants With Microbiological Response at the Test of Cure (ToC) Visit
Day 10 to Day 13 (ToC Visit)

Microbiological response (success/failure) is used to measure microbiological efficacy. Microbiological success was defined as a reduction in E. coli count to less than (\<) 10\^3 colony-forming units (CFU) per milliliter (CFU/mL) for any E. coli at the ToC visit. Microbiological failure included all other microbiological outcomes (for example but not limited to \>=10\^3 CFU/mL for any E. coli identified at ToC visit, use of rescue medication prior to ToC, lost to follow-up before ToC, missing/unevaluable samples at ToC, etc).

Secondary Endpoints
Number of Participants With Adverse Events (AEs)
From the first dose of study intervention up to Follow-up Visit (up to Day 31)
Number of Participants With Serious AEs (SAEs)
From the signing of informed consent up to Follow-up Visit (up to Day 31)
Number of Participants With Clinically Significant Changes in Vital Signs Findings
Up to Day 31
