Bettoli V, et al. - Purulent material from 137 skin lesions was estimated to assess the prevalence and antibiotic (AB) resistance of bacterial growths in hidradenitis suppurativa (HS) cases and also to estimate the clinical relevance of collected data in the management of the disease. They collected samples from the axillae, groin and perianal areas and observed 163 single bacterial growths (55% Gram-positive and 44% Gram-negative). The most prevalent families were enterobacteriaceae (30.7%), Staphylococcus (25.2%) and Streptococcus (14.1%) whereas most common genus/species were Proteus spp. (13.5%) and Escherichia coli (9.8%). They noted a higher prevalence of AB resistance for clindamycin, rifampicin, penicillin, ciprofloxacin, tetracycline, and erythromycin.
