Hulterström AK, Sellin M, Berggren D. The microbial flora in the nasal septum area prone to perforation. APMIS 2012; 120: 210–4. To explore the colonizing bacterial flora of the nasal septum area, that is mostly afflicted by perforations, 101 healthy police students had swab samples taken from that location. The described culture strategy recovered positive cultures from 95% of the test subjects and from 60% with more than one organism. In total, 191 bacterial isolates were classified according to colony morphology, Gram‐stain and a panel of standard laboratory techniques. A part of the bacteria was identified to species‐level by biochemical methods and by sequencing of the 16S rRNA gene. The predominant finding was Gram‐positive irregular rods – 65 presumptive Corynebacterium isolates, both lipophilic and non‐lipophilic, and 37 anaerobic Propionibacterium isolates. The second largest bacterial group was Gram‐positive catalase‐positive cocci, of which 13 isolates were identified as Staphylococcus aureus and 53 as coagulase‐negative staphylococci. The few potential airway pathogens included Streptococcus pneumonia (n = 1) and Moraxella catarrhalis (n = 3) isolates. The bacterial flora colonizing the nasal septum mainly consists of Gram‐positive bacteria. Although of low virulence, the microbial flora may impact on occlusion treatment of nasal septum perforations with silicone obturators.
