Brief Summary:
This research focuses on antibiotic resistant bacteria that may reside in the digestive tract (intestinal flora) of everyone.
When we develop an infection, the bacteria in question is, often, already present in our flora. Face to the growing phenomenon of multi-resistance, which is a public health problem, it is essential to follow the frequency of these bacteria but also to find new strategies and effective means to fight against their spread.
It has been discovered long time ago that it exists viruses able of destroying bacteria: they have been called bacteriophages .They was used before the arrival of antibiotics for the treatment of various infections (phagotherapy). Today, with the problems of resistance, phagotherapy could become a good way to fight against infections with bacteria very resistant but also a way to remove the resistant bacteria that are present in our digestive flora.
Moreover, it is known that these viruses of bacteria are present everywhere in the environment (waters, soils, human digestive tract and animal), it is important to check their presence in our digestive tract. Our objective is to study if the presence of these phages prevents resistant bacteria from set up in our digestive flora.
To answer the question, it is planned to include 460 people hospitalized in intensive care unit (resuscitation). The choice of this unit is linked to the fact that the monitoring of resistant bacteria is carried out regularly during the hospitalization. Three resuscitation services were recruited: 2 in Saint Antoine Hospital and 1 in Tenon Hospital. On stool samples collected at different times of the stay (admission and then during the stay), we will look for 2 types of bacteria and viruses capable of destroying them.

Detailed Description:
Evaluate the association between the presence of phage (s) in patients not carrying E. coli or K. pneumoniae ESBL or carbapenemase (EPC) (Ec-ESBL / EPC or Kp-ESBL / EPC) and subsequent acquisition Of carrying Ec-BLSE / EPC or Kp-BLSE / EPC during their stay in intensive care.
Collection of stools of the patients included at the admission then in a successive way. On the first stool, search for multiresistant bacteria. If positive research: search for bacteriophage directed against the strain of the patient bearing. Continued screening of stools from non-carriers at baseline.
In patients defined as non-carriers at the end of the inclusions and collection, selection of 8 stools for the detection of bacteriophages directed against all BMR strains which were isolated during the study period.
