Children's nasal carriage of Streptococcus pneumoniae
Official title: Observatory of Streptococcus Pneumoniae Nasopharyngeal Carriage in Infants With Acute Otitis Media (AOM) and in Healthy Children"
Run by Association Clinique Thérapeutique Infantile du val de Marne · NCT04460313 · Data updated 2026-11-12
This project will test whether pneumococcal vaccines changed which Streptococcus pneumoniae types children carry in their noses and whether those bacteria became more resistant to antibiotics.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children seen in participating outpatient pediatric clinics who are either 6–36 months with suppurative acute otitis media or healthy children aged 6 months–15 years, whose parents provide consent and who have not taken antibiotics within 7 days before enrollment.
✕Probably not a fit
Children with severe underlying disease, those enrolled in the study in the prior 12 months, those with bullous myringitis, or those recently treated with antibiotics are excluded and unlikely to benefit from participation.

What this trial studies
Beginning in 2001, pediatricians in the ACTIV network across France enrolled children with suppurative acute otitis media (ages 6–36 months) and a separate group of healthy children (ages 6 months–15 years) during the October–June seasons each year. All participants had nasopharyngeal samples collected, with optional stool or anorectal swabs and an ancillary subgroup tested for ESBL-producing E. coli. Collected samples were serotyped and tested for antibiotic susceptibility to detect shifts in serotype distribution and resistance patterns after introduction of 7- and 13-valent pneumococcal conjugate vaccines. The study was conducted in outpatient pediatric settings with standardized sample collection and laboratory analysis over multiple years.
Why it matters
Potential benefit: If successful, the findings could help guide vaccine policy and antibiotic prescribing to reduce resistant pneumococcal infections in children.
How similar studies have gone: Other national and regional surveillance studies have documented vaccine-driven serotype shifts and changes in pneumococcal antibiotic resistance, so this approach is consistent with prior successful surveillance efforts.
