Brief summary: The propias, and more recently the update of the recommendations relating to the control of the spread of bacteria highly resistant to emerging antibiotics issued by the High Council of Public Health (December 2019), recommend the implementation of measures to maintain the rate of Carbapenemase-producing Enterobacteriaceae (EPC) such as Klebsiella pneumoniae (K. pneumoniae) isolated from bacteremia in healthcare establishments in France at less than 1%, and that of Vancomycin Resistant Enterococcus (VRE) belonging to Enterococci Resistant to Glycopeptides (ERG) such as Enterococcus faecium isolated from bacteremia in health establishments in France at less than 1% also. At the same time, the prevalence of colonized patients is increasing. One of the recommended measures concerns the fight against cross transmission.

Due to the high technicality of the treatments, the risks of cross-transmission are very high and present at each stage of the dialysis procedure. Screening and isolation of patients colonized with emerging Highly Resistant Bacteria (BHRe) is essential to avoid their spread and the risk of infection with these germs.

Screening is done using rectal swabs. If the patient is found to be a carrier of BHRe, he should be isolated. Isolation is made more difficult in the hemodialysis room due to their architectural configuration, the organization of care and the chronicity of the patients. Patients have a monthly sample.

The isolation is allowed after obtaining six consecutive negative rectal swabs, the number of which has been arbitrarily defined. Indeed, the negativation of the samples does not confirm the disappearance of the carriage (that is to say the presence of BHRe), hence the need to repeat them. Persistence of colonization at a rate below the detection limit is possible. With for corollaries:

* Isolation which could be lifted more quickly in the event of real disappearance of the strain since the investigators know that a prolonged period of isolation can lead to a loss of opportunity for the patient and the investigators know its impact for the patient, on the operation of the service and its cost, with in particular the increase in withdrawals.
* Isolation lifted too early in the event of persistent carriage with risk of secondary transmission.

The interest of this study is to determine the clearance of the carriage of BHRe, i.e. their disappearance, in the chronic dialysis patient and to define, secondly, the factors associated with the prolonged carriage corresponding to the presence of bacteria for more than 3 months. , and elements of answer concerning the early disappearance of the EPC in the event of co-colonization by ERG and EPC. The follow-up of this carriage for 1 year will make it possible to evaluate the relapse corresponding to the reappearance of the bacteria previously identified, the recolonization corresponding to the acquisition of a new BHR, or the reinfection corresponding to an infection with a new highly resistant bacterium.
