Sickle cell disease children’s gut colonization by extended-spectrum β-lactamase (ESBL)-producing Enterobacterales: an antibiotic prophylaxis effect? (original) (raw)

Journal of Medical Microbiology

Abstract

Introduction. Sickle cell disease (SCD) children have a high susceptibility to pneumococcal infection. For this reason, they are routinely immunized with pneumococcal vaccines and use antibiotic prophylaxis (AP). Hypothesis/Gap Statement. Yet, little is known about SCD children’s gut microbiota. If antibiotic-resistant Enterobacterales may colonize people on AP, we hypothesized that SCD children on AP are colonized by resistant enterobacteria species. Objective. To evaluate the effect of continuous AP on Enterobacterales gut colonization from children with SCD. Methodology. We analysed 30 faecal swabs from SCD children on AP and 21 swabs from children without the same condition. Enterobacterales was isolated on MacConkey agar plates and identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) (bioMérieux, Marcy l'Etoile, France). We performed the antibiogram by Vitek 2 system (bioMérieux, Marcy l'Etoile, France), and the resis...
