Abstract

Objective: Oral candidiasis, in the form of Candida-associated denture stomatitis, represents a common disease in a large percentage of denture wearers, and Candida albicans remains the most commonly isolated species. In this study, we aimed to evaluate biofilm production, coagulase and hemolytic activity of Candida species isolated from denture stomatitis patients. Materials and Methods: This study included 70 patients (31 female, 39 male). Forty-eight of the patients were found to have a positive culture. A total of 48 Candida isolates representing five species, C. albicans (n=17), C. glabrata (n=10), C. krusei (n=9), C. kefyr (n=7) and C. parapsilosis (n=5), were tested. Their coagulase activities were evaluated by a classical tube coagulase test with rabbit plasma. A blood plate assay on 3% enriched sheep blood Sabouraud-dextrose agar (SDA) was used to determine their in vitro hemolytic activities. Biofi lm production was determined by a visual tube method.Results: Twenty-one Candida isolates exhibited coagulase activity, and the coagulase activities of the C. albicans (64.7%) isolates were higher than other species. C. albicans, C. glabrata, C. kefyr and C. krusei species demonstrated beta hemolysis. C. parapsilosis strains failed to demonstrate any hemolytic activities. Fifteen (88.0%) of the C. albicans strains were biofilm positive. Six (35.2%) of these strains were strongly positive, 8 (47.0%) C. albicans strains were moderately positive and 1 (5.8%) C. albicans strain was weakly positive. Sixteen (51.6%) of the non-albicans Candida strains were biofilm positive while 15 (48.3%) did not produce biofilms.Conclusion: The results of this present study indicate coagulase, hemolytic activity and biofilm production by Candida spp. isolated from patients with denture stomatitis. Investigations of these virulence factors might be helpful in gaining information about the possible virulence of oral Candida species related to denture stomatitis.

Özet

Amaç: Oral kandidiyazisin Candida ile ilişkili olarak gelişen protez stomatiti şekli, protez kullananların büyük bir kısmında görülen yaygın bir hastalıktır ve Candida albicans en çok izole edilen türdür. Bu çalışmada, protez stomatitli hastalardan izole edilen Candida türlerinde biofilm üretimi, koagülaz ve hemolitik aktivite araştırılması amaçlanmıştır. Gereç ve Yöntem: Bu çalışma 31 kadın, 39 erkek toplam 70 hasta üzerinde yürütüldü. Hastaların 48'inde kültür pozitif bulundu ve izole edilen 48 Candida suşu 5 tür olarak tiplendirildi [(C. albicans (n=17), C. glabrata (n=10), C. krusei (n=9), C. kefyr (n=7), C. parapsilosis (n=5)]. Suşların koagülaz aktivitesi tavşan plazması kullanılarak klasik tüp koagülaz testi ile hemolitik aktiviteleri ise %3 glikoz ile zenginleştirilmiş koyun kanlı Sabouraud-dextrose agar (SDA) kullanılarak araştırılmıştır. Biofilm üretimi tüp adherans testi ile belirlenmiştir.Bulgular: Yirmibir Candida izolatında koagülaz üretimi belirlenmiş ve koagülaz aktivitesi Candida albicans (%64.7) suşlarında diğerlerinden daha yüksek bulunmuştur. Candida albicans, Candida glabrata, Candida kefyr ve Candida krusei suşları beta hemoliz oluşturmuştur. Candida parapsilosis suşları hemolitik aktivite göstermemiştir. On beş (%88.0) C. albicans suşu biofilm oluşturmuş, bunların altısında (%35.2) kuvvetli, sekizinde (%47.0) orta dereceli ve birinde (%5.8) zayıf biofilm oluşumu belirlenmiştir. On altı (%51.6) non-albicans Candida türünde biofilm oluşumu pozitif bulunurken, 15'inde (%48.3) biofilm üretimi belirlenememiştir.Sonuç: Bu çalışma sonucunda protez stomatitli hastalardan izole edilen Candida türlerinde koagülaz, hemolitik aktivite ve biofilm üretimi belirlenmiştir. Bu faktörlerin araştırılması protez stomatit ilişkili Candida türlerinin muhtemel virulansları hakkında bilgi vermesi açısından faydalı olabilir.
