An observational study in Pneumococcal Carriage, sponsored by University of Central Florida. Recruiting at 1 site in United States. Open to participants aged 7 Months and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-12-06.
Sponsored by University of Central Florida · Observational
The PI propose to conduct a genomic epidemiology study of pneumococcal carriage among children and adults in a large metropolitan city. These data will allow PI to assess the post-pandemic population structure, investigate the phylogenetic relationship between isolates from children and adults, and compare pneumococcal populations across diverse geographic areas.
The SARS-CoV-2 pandemic profoundly impacted human health directly and indirectly. As such, elucidating pre- and post-pandemic trends in the epidemiology and population genomics of human respiratory pathogens including those such as the bacteria Streptococcus pneumoniae, a human commensal and the causative agent of invasive pneumococcal disease (IPD), merits study.
Nasopharyngeal samples will be processed at the PIs Laboratory to identify S. pneumoniae. If present, the isolate will undergo bacterial whole genome sequencings and population dynamic analysis. Carriage prevalence and serotype composition will be compared to extant studies and pneumococcal genomic data will be analyzed in the context of samples from the US and abroad.
University of Central Florida is the lead sponsor of 99 studies on the registry; 40 are open to participants now.
Counted across the registry records on this site, refreshed daily.
The PI seeks to recruit 450 children 7-59 months of age and 450 adults 50 years or older over a 16-month period. Children will be equally distributed between 7-23 months and 24-59 months and adults equally distributed in the age ranges: 50-64 years, 65-74 years, and 75 years or older.
Pregnant women may choose to be in the study. The study procedures do not pose a risk to the safety of the unborn child or the woman.
Exclusion Criteria:
This is a non-interventional study with data collection online, chart review, and biospecimen collection (nasopharyngeal swab). The swab will then be used for biomarker discovery. Findings will be compared and analyzed between the children and adult groups.
