Preliminary epidemiological screening of Staphylococcus aureus carriage in the upper respiratory tract of healthy people living in Lubelszczyzna region
Keywords:
Staphylococcus aureus, nasal carriage, throat carriageAbstract
Epidemiological screening of Staphylococcus aureus carriage in the upper respiratory tract was performed in healthy people living in two districts from Lubelszczyzna region – Zwierzyniec and Wilków. Three types of carriage were found: exclusive nasal carriage, “mixed” nasal and throat carriage, as a consequence of staphylococci migration from anterior nares to throat, and exclusive throat carriage. The rates of the carriage in healthy people from Zwierzyniec, Wilków or the pooled population were 19.42 %, 32.90%, 25.14% in the case of exclusive nasal carriage, 5.83%, 11.84%, 8.35% in the case of “mixed” carriage or 12.62%, 5.26%, 9.50% in the case of exclusive throat carriage; the rates of nasal carriage, including exclusive nasal carriage plus “mixed” nasal and throat carriage were the following – 25.25%, 44.74%, 32.49%. The rates of nasal S. aureus carriage were statistically significantly higher than those of throat carriage. In order to improve the likelihood of detection of S. aureus carriage within the upper respiratory tract both nasal and throat carriage must be considered.
