Over-infection by Candida spp and Staphylococcus aureus in patients with angular cheilitis
##plugins.themes.bootstrap3.article.details##
BACKGROUND: Angular Cheilitis, also called candidiasis by predisposition, is known as a mycotic colonization at the labial commissure due to deep fold or epidermal erosions. It usually is bilateral, does not bleed, and is limited to the vermilion and to the cutaneous surface. A relationship with the presence of microorganisms like Staphylococcus aureus and Candida albicans has been reported; additionally, it is likely associated to a vertical dimension reduction which can be an adjuvant factor for the angular Cheilitis pathogenesis. OBJECTIVE: To observe if an over-infection with Candida Spp and Staphylococcus aureus exists in patients with angular Cheilitis, with or without lost of vertical dimension. METHOD: Microscopic and biochemical characterizations were done to 30 samples of adult patients with clinical signs of angular Cheilitis, 15 patients with lost of vertical dimension and 15 patients without that lost. RESULTS: 4 types of microorganisms were associated to angular Cheilitis, Staphylococcus epidermidis, Staphylococcus aureus, Candida Spp and Streptococcus, in descendent order of frequency. In most of the samples a single microorganism was found. CONCLUSIONS: The angular Cheilitis could not be defined exclusively as an atrophic candidiasis since the presence of other microorganisms indicates a multifactorial etiology.
