Is Strep Group F considered a pathogen or normal flora in a throat culture? What does it cause? Strep throat or anything else? Particulary in cystic fibrosis patients?
The data in the literature would state that Group A, C, and G would be considered potential causes of pharyngitis. They may cause pharyngitis in CF patients as well. There are no data to suggest that Group F strep has any role in pharyngitis in non-CF patients nor any role in CF lung disease. One caveat, based on data generated by molecular amplification techniques, one group of investigators is suggesting that anaerobes and other members of the oropharyngeal microflora which might include Group F might be involved in chronic CF lung infection. These data are not yet ready for prime time but they are interesting. We hope that we were able to answer your question. Please visit us again at the American Society for Microbiology.
