A profile of Propionibacterium acnes resistance and sensitivity at a tertiary dermatological centre in Singapore

Propionibacterium acnes (P. acnes) is a key component in the pathogenesis of acne. Both topical and oral antibiotics are key therapeutic options. Unfortunately, antibiotic resistance is rapidly increasing globally. Many countries have reported greater than 50% of P.acnes strains acquiring resistance to topical macrolides^1-3. In Singapore, antibiotic resistance rates of 8% in 1999⁴ rising to 14.9%⁵ in 2007 were reported. We aimed to update the local prevalence of antibiotic resistance and identify features which may distinguish patients demonstrating antibiotic resistance from those who are pan-sensitive.
