22 633 (34 3%) of 1847 travellers had acquired ESBL-E during international travel, especially in southern Asia (75 1%). Median duration of colonisation after travel was 30 days. 65 (11 3%) of 577 remained colonised at 12 months. Onward transmission was found in 13 (7 7%) of 168 household members. The probability of transmitting ESBL-E to another household member was 12%. Calculated effective R0 was around 0.2 (Martin Bootsma personal communication), which might include some overestimation due to false-positive transmission events (no molecular typing).

37 Hypothesis: Infections caused by antibiotic resistant bacteria increase the risk of recurrent infetion. Aim: To quantify the association between antibiotic resistance and the occurrence of recurrent bacteremia. Data source: All blood cultire isolates of Enterobacteriaceae in ISIS- AR, covering 60% of all microbiological culture results since 2010 (analysis till Sept 2016).

38 ESBL ESBL+CRE ESBL ESBL+CRE The absolute risk of a recurrent infection caused by ESBL or ESBL/CRE after a first episode caused by a susceptible isolate was 0.1% (74/ episodes). The estimated number of recurrent bacteremia episodes with ESBL or ESBL/CRE in the Netherlands is 19/year.

39 we used genomics to analyze a systematic 11-yr hospitalbased survey of E. coli associated with bacteremia using isolates collected from across England by the British Society for Antimicrobial Chemotherapy and from the Cambridge University Hospitals NHS Foundation Trust.
