The effects of regular hot black tea consumption on nasal carriage of methicillin-resistant Staphylococcus aureus.

Abstract

OBJECTIVES This study aims to evaluate the possible relationship between oral consumption of hot black tea and methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage in a mid-sized town population in central Anatolia. PATIENTS AND METHODS Nasal swabs were taken from a total of 109 subjects (53 females, 56 males; mean age 34.4 years; range 18 to 65 years) including 55 non-tea drinkers and 54 subjects consuming more than 10 cups of tea a day. The MRSA positivity in the nasal cultures was investigated. RESULTS In the tea consumer group MRSA was cultured in 10 subjects. Twenty-one subjects' nasal cultures were positive for MRSA in the non-tea drinkers. We found a statistically significant difference in the nasal MRSA carriage among tea drinkers and non-tea drinkers. CONCLUSION Our study findings indicate a lower incidence of nasal MRSA carriage in tea drinkers, suggesting that certain soluble tea compounds may exhibit some antibacterial properties when consumed orally.
