Knowledge about the duration of digestive carriage of ESBL- and carbapenemase-producing Enterobacteriaceae is an essential information, impacting clinical decisions (empiric treatment for known carriers) and infection control measures (preemptive precautions, sequential screening). Ten to 50% carriers are still colonized after one year, but these numbers might be overestimated. Use of genomic typing is required to distinguish endogenous long-term carriage from exogenous recolonization events. Median length of colonization appears to range between 0,5 and 13 months for E-ESBL and 0,7 to 10 months for CPE. We performed a narrative review of the literature on this topic. We finally suggest a few future perspectives.La durée de colonisation digestive par les |
