The purpose

The purpose of this study is to find out if the bacteria present in the nose or sinuses of people with seasonal allergies changes during their allergy season. Another purpose of this study is to see if the bacteria present in the nose and sinuses of non-allergic people are the same as allergic people before the allergy season and if it changes during the season. Many bacteria are difficult to grow in the laboratory so the investigators are using analysis of DNA (the genetic material in cells) of the bacteria in the nose and sinus to find them. The investigators will be testing DNA of the bacteria only and not of the human subjects taking part in this study. This research is being done to help us understand how allergy affects bacteria in the nose and sinuses.
