The researchers from The University of Pennsylvania School of medicine examined the prevalence of Staphylococcus aureus bacteria on at least 83 patients who are treated for acne.
The researchers wrote in the journal “While S.aureus colonizes the skin,it can also be responsible for localized cutaneous or skin infection and life threatening systematic infections.”
They further says “Long term use of antibiotics decreased the prevalence of S.aureus colonization by nearly 70 percent.A decreased rate of colonization was noted with the use of both oral and topical antibiotics.”
Surprisingly the study contradict the current beliefs about long term use of antibiotics.
Dr.Doris Day, a dermatologist at Lenox Hill Hospital in New York city says “The result of the study correlate well with our experience minimal to no general bacterial resistance.”However our great concern is that long term use of tetracycline’s and other antibiotics used to treat acne can lead to resistance of the specific bacteria that is underlying culprit in most of the cases of acne,the P.acnes bacteria.”
