Abstract

We investigated the bacteria present in 62 cases of inflammation of the nasal vestibule. Staphylococcus aureus was the most frequently observed bacterium, and was present in 56 cases (90.3%). MSSA (methicillin-sensitive Staphylococci) were found in 40 cases (64.5%) and MRSA (methicillin-resistant Staphylococci) were found in 16 cases (25.8%). CNS (coagulase-negative Staphylococci) were present in three cases. Bacteria that cause sinusitis were rarely observed. We consider that angular cheilitis is often caused by the bacteria preset in saliva, while inflammation of the nasal vestibule is not caused by bacteria in nasal discharge, but by the normal flora following activation by some type of stimulus. The stimulation might be related to allergic rhinitis or the common cold, because it often occurs during the pollinosis season or in the winter, and rarely in the summer. The most effective antibiotic against MSSA was FMOX (100%), followed by MINO (97.5%). MRSA is classified into communityacquired MRSA (CA-MRSA), which is sensitive to MINO, and into hospital-acquired MRSA (HA-MRSA), which is resistant to most antibiotics. CA-MRSA accounted for 10 out of 16 cases of MRSA (62.5%). A high percentage (30.1%) of the patients older than 60 years showed MRSA colonization, and all six cases of HA-MRSA were included in this age group.
