Populærvitenskapelig sammendrag av avhandlingen/ Summary of the thesis

The common, but deadly bacteria Staphylococcus aureus can be found in the nasal cavity of 30 % of healthy adults. These human carriers have increased risk of serious infections and of transmission of the bacteria.

Former studies have shown that male sex and younger age are the two most important risk factors for carriage, could this be because of sex hormones? In this thesis we examined if hormonal exposures influence carriage of this bacteria, and if transmission between humans follows friendship ties.

We used the Norwegian youth health survey Fit Futures to show higher risk of carriage in females using hormonal contraceptives, and the adult health survey, Tromsø 6 study, to show lower risk of carriage with increasing levels of testosterone in women. We also demonstrated transmission of the bacteria through a social network of youths.

We hope that these results will provide better understanding of bacterial carriage, and eventually lead to treatment and elimination of carriage status.
