Candida albicans is normal flora found in the oral mucosa in healthy individuals but has opportunistic pathogenic properties. The change in the oral cavity's environmental conditions can cause C. albicans to turn into a pathogen and cause oral candidiasis. Antifungal drugs that are common used for the treatment of oral candidiasis are topical nystatin preparations. Nystatin is an antifungal drug from the polyene group produced by Streptomyces noursei, which is thought to be very effective in treating diseases caused by C. albicans with a success rate 79.6 - 87.5%. The previous study showed that watermelon peel extract contains active compounds of alkaloids, flavonoids, tannins, and saponins. The active compound is known to have antifungal activity. The study aimed to determine the ability of watermelon peel extract to inhibit the growth of C. albicans. The type of research conducted is experimental laboratories using the post-test only control group design. The observations in this study about the inhibitory power of watermelon rind extract (Citrullus lanatus) on the growth of C. albicans showed that there were inhibitory zones of watermelon skin extract on the growth of C. albicans.

Denture cleaning is needed to keep the denture base clean from contamination by microorganisms. Celery leaves are natural ingredients that contain flavonoids, saponins, tannins, and essential oils that have been proven to have antifungal properties. Previous research only observed the inhibitory zone. This research was aimed to analyse the effectiveness of celery leaf juice as a denture cleaner against the growth of Candida albicans on thermoplastic nylon denture base. Methods: Experimental laboratory with a post-test only control group design was conducted towards 25 disc-shaped thermoplastic nylon samples with a diameter of 10 mm and a thickness of 2 mm, and divided into five groups. Samples were contaminated with C. albicans after immersion in the negative control (aquadest) for 6 hours, positive control (effervescent tablets) for 15 minutes, and celery leaf juice with the concentrations of 25, 50, and 100% for 6 hours. The sample was then placed in the Sabouraud-dextrose broth (SDB) medium. The effectiveness of celery leaf juice was tested by determining the absorbance value of SDB media turbidity using a spectrophotometer. Data were analysed using one-way ANOVA and Least Significant Difference (LSD). Results: The concentration value of C. albicans in the negative control group was 0.380 x 108 CFU / mL, the positive control was 0.310 x 108 CFU / mL, the juice of celery leaves with the concentration of 25% was 0.243 x 108 CFU / mL, the concentration of 50% was 0.160 x 108 CFU / mL, and the concentration of 100% was 0.236 x 108 CFU / mL. Conclusion: Celery leaf juice is effective as a denture cleaner to inhibit the growth of C. albicans, with an effective concentration of 50%.Keywords: Thermoplastic nylon, celery leaf juice, Candida albicans.

Background/Aim. Oral candidiasis frequently causes discomfort in patients treated for malignant diseases, acting as well as a potential source of systemic infection. This disease may present itself through different clinical manifestations of both acute or chronic type. The aim of this study was to identify different Candida species from oral cavities of patients suffering from malignant diseases. Methods. Thirty patients admitted to the hospital for diagnostics/treatment of malignant diseases were included in this investigation. All subjects had visible changes of oral mucosa in the form of pseudomembranes and inflammation corresponding to oral candidiasis. Control group included 30 non-hospitalized patients diagnosed with candidiasis. Diagnosis of oral candidiasis was confirmed in all patients by microbiological analysis of tongue swabs. For microbiota identification, three different tests were used: germination test, fungal growth test on corn meal agar, and biochemical identification with commercially available ID 32 C kit (bio-Merieux, Marcy-l?Etoile, France). Results. Out of 30 isolates collected from hospitalized patients, 90% was related to Candida albicans, 7% was identified as Candida kefyr, and 3% as Candida famata. In samples collected from non-hospitalized controls, we isolated Candida albicans in 90% of the cases, in 7% Candida kefyr, while in 3% we identified Candida glabrata. Conclusion. Based on this investigation, oral candidiasis in patients treated with radiotherapy and chemotherapy is mainly caused by Candida albicans. It is to be expected that Candida albicans will remain the most significant causative agent of oral candidasis, although we must bear in mind the possibility of other pathogenic species.

Abstrak   Candida albicans merupakan salah satu mikrooganisme penyebab infeksi kandidiasis. Daun sirih merah (Piper crocatum) dan biji alpukat (Persea americana) telah diteliti dapat menghambat pertumbuhan Candida albicans. Tujuan penelitian ini adalah untuk mengetahui efektivitas kombinasi daun sirih merah (Piper crocatum) dan ekstrak biji alpukat (Persea americana) dalam menghambat pertumbuhan Candida albicans. Penelitian bersifat eksperimental laboratorium (true experiment) dengan pendekatan post test control group design only. Daun sirih merah dan biji alpukat diekstraksi secara maserasi menggunakan pelarut etanol.    Pada masing-masing ekstrak etanol dilakukan uji pendahuluan untuk mengetahui konsentrasi optimum ektrak dalam memnghambat pertumbuhan C. albicans. Daya Hambat pertumbuhan C. albicans diuji menggunakan metode difusi. Hasil penelitian menunjukkan bahwa ekstraks daun sirih merah dan biji alpukat masing-masing memiliki daya hambat terbesar pada konsentrasi 10%. Kombinasi ekstrak daun sirih merah dan ekstrak biji alpukat memiliki daya hambat yang signifikan terhadap pertumbuhan Candida albicans dibandingakan kontrol negatif, kontrol positif dan ekstrak daun sirih merah. Dengan demikian kombinasi ekstrak daun sirih dan biji aplukat etanol berpotensi sebagai antifungi dalam menghambat pertumbuhan C. albicans sehingga diharapkan bisa mengurangi prevalensi kandidiasis. Kata Kunci :    daun sirih merah,  biji alpukat, Candida albicans,                                                           Abstract Candida albicans is one of the microbialism that causes candidiasis infection. Red betel leaf (Piper crocatum) and avocado seed (Persea americana) have been studied to inhibit the growth of C. albicans. The purpose of this study was to determine the effectiveness of red betel leaf (Piper crocatum) and avocado seed extract (Persea americana) combination in inhibiting the growth of C. albicans. Research is experimental laboratory (true experiment) with post test approach control group design only. Red betel leaf and avocado seeds are extracted by maceration using ethanol solvent. In each ethanol extract, a preliminary test was performed to find out the optimum concentration of extract in inhibiting the growth of C. albicans. C. albicans growth retardant was tested using diffusion method. The results showed that the extract of red betel leaf and avocado seeds each had the greatest inhibitory concentration at 10%. The combination of red betel leaf extract and avocado seed extract have significant inhibitory effect on C. albicans growth compared to negative control, positive control and red betel leaf extract. Thus, the combination of betel leaf extract and ethanol  seed has the potential as an antifungal in inhibiting the growth of C. albicans so it is expected to reduce the prevalence of candidiasis. Keywords: red betel leaf, avocado seed, Candida albicans,
