About

Antibiotic resistance is a major public health issue as multiresistant bacteria (MRB) are increasing. Among the actions to control resistance, one is an interesting lead: to prevent the emergence of resistant bacteria by limiting possibilities for bacteria to acquire resistance. Mechanisms of resistance genes acquisition are deeply studied but there are few data on the dynamic of acquisition over time. Among the genetic components that disseminate resistance genes, resistance integrons (RI) play a major role in the acquisition and dissemination of antibiotic resistance in gram-negative bacteria. The digestive tract of the newborn (NB), which is initially sterile, is colonized by a bacterial microbiota during the first days of life. It thus appears to be an appropriate model to study the dynamic of resistance acquisition. This project intends to follow the NB of neonatology over time in order to study the dynamic of the digestive acquisition of RI and MRB

Enrollment: 278 patients

Sex: All

Ages: Under 1 day old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Mother-child pairs that will be included in the study will be the pairs of all the NB, born in the center (in born) and hospitalized in the neonatology units of each center:

with a predictable stay ≥ 3 weeks in the unit

Exclusion criteria

NB will not be included if:

• They exhibit a birth defect, especially on the digestive tract
• They are secondarily hospitalized after a postnatal transfer (out born).
• The parents express their objection for the child to take part in the study
• The stool sample of the mother has not been received
