Staphylococcus aureus is a frequent inhabitant of the nasal cavity and can change from an opportunistic pathogen to a threat, particularly in clinical environments. Although the sociobiology and immunobiology of colonization have been thoroughly examined, the possibility of the nasal structure assisting bacterial retention is still under investigation. Examine the relationship between the structural variations of the nasal cavity and the susceptibility to colonization of Staphylococcus aureus among fully grown adults without any nasal infections.
