Thanks for responding. The first was (2018) and associated with apparent diverticulitis and diagnosed after ER and admission after blood culture - bacteria had entered the bloodstream requiring 30 + days of IVs of meropenem in hospital and at home. The second was after Mohs surgery for squamous cell on left hand. Culture of the wound determined a second infection .Of interest, after 2020 TAVR at Mayo I take an antibiotic to prevent infections.
