"Penyebab utama kandidiasis yang merupakan infeksi jamur tersering pada manusia, adalah Candida albicans. Asupan glukosa yang tinggi merupakan salah satu faktor predisposisi kandidiasis oral. Substitusi asupan glukosa dengan xylitol dilaporkan mampu mengontrol pertumbuhan C. albicans. Berbagai penelitian in vitro terdahulu tentang konsentrasi efektif xylitol dalam menghambat pertumbuhan C. albicans bervariasi, yaitu xylitol 1%, 5%, atau 10%.Tujuan: Mengetahui pengaruh konsentrasi dan durasi pemaparan xylitol dalam menurunkan jumlah koloni C. albicans in vitro.Metode: Sampel C. albicans diambil dari usapan lesi mukosa mulut seorang pasien laki-laki penderita kandidiasis oral. Identifikasi spesies menggunakan CHROMagar dan uji serum. Setelah teridentifikasi positif, dibuat suspensi C. albicans pengenceran 108 kali. Pemaparan xylitol konsentrasi 1%, 5%, 10% (kelompok uji) serta tanpa xylitol (kelompok kontrol) dilakukan dalam Sabouraud Dextrose Broth (SDB) selama 3 hari dan 7 hari. Selanjutnya, C. albicans diinkubasi pada suhu 37oC selama 48 jam dalam Sabouraud Dextrose Agar (SDA) untuk mendapatkan jumlah CFU/ml. Sebagai pembanding, prosedur yang sama dilakukan terhadap C. albicans strain ATCC 10231.Hasil: Pada kultur C. albicans yang diberi xylitol selama 3 hari, peningkatan konsentrasi xylitol menyebabkan penurunan jumlah koloni C. albicans secara bermakna (p = 0,044). Konsentrasi xylitol 10% menyebabkan penurunan jumlah koloni C. albicans yang sangat bermakna dibandingkan kontrol (p = 0,024). Pada kultur C. albicans yang diberi xylitol selama 7 hari, konsentrasi xylitol tidak mempengaruhi jumlah koloni C. albicans secara bermakna (p = 0,396).Kesimpulan: Konsentrasi dan durasi pemaparan xylitol mempengaruhi efek xylitol dalam menurunkan jumlah koloni C. albicans in vitro. Pemaparan xylitol 10% selama 3 hari sangat berpengaruh dalam menurunkan jumlah koloni C. albicans in vitro.

Candidiasis which is the most common fungal infection of human, primarily caused by Candida albicans. The growth of C. albicans is influenced by glucose intake. Substitution of glucose intake with xylitol is reported to inhibit the growth of C. albicans. Several previous studies reported various concentrations of xylitol, 1%, 5%, or 10%, as an effective concentration in inhibiting C. albicans in vitro.Objectives: Investigating the effect of different concentration and duration of xylitol exposure in inhibiting C. albicans growth in vitro.Methods: C. albicans sample was taken from oral swab of a male oral candidiasis patient. Identification of C. albicans was conducted using CHROMagar, confirmed by germ tube test. The cultures were serially diluted and inoculated in Sabouraud Dextrose Broth (SDB) contained 1%, 5%, 10% xylitol, and without xylitol (as control), for 3 and 7 days. These inoculations were then incubated in 37oC on Sabouraud Dextrose Agar (SDA). The Colony Forming Unit (CFU) were counted after 48 hours. As a comparison, the same procedure was conducted for the C. albicans ATCC 10231 strain. Results: After 3 days, increased concentration of xylitol added to C. albicans media lead to decreased growth of C. albicans significantly (p = 0,044). Ten percent xylitol resulted in significant lower growth of C. albicans compared to control (p = 0,024). After 7 days, there?s no significant effect of the three concentrations of xylitol in decreasing the growth of C. albicans (p = 0,396).Conclusion: Concentration and duration of xylitol exposure influent the inhibitory effect of xylitol on the growth of C. albicans. Three days exposure of 10% xylitol could significantly inhibit the growth of C. albicans in vitro."

"Faktor serum yang bersifat antimikroba seperti komplemen dapat menghambat pertumbuhan C. albicans. Konsumsi xylitol dilaporkan mampu menekan pertumbuhan C. albicans. Tujuan: Menganalisis efek xylitol 1%, 5%, 10% selama 3 hari atau 7 hari terhadap resistensi C. albicans dalam serum in vitro, dan menganalisis peran faktor serum dalam menghambat C. albicans dalam serum. Metode: Deteksi C. albicans yang diambil dari lesi mulut pasien kandidiasis oral dilakukan dengan menggunakan media CHROMagar dan dikonfirmasi dengan uji pembentukan germ tube. Setelah melalui tahap pengenceran, C. albicans dipaparkan dengan larutan xylitol 0% (kontrol), 1%, 5%, dan 10% yang dilarutkan dalam media Sabouraud Dextrose Broth (SDB) selama 3 hari atau 7 hari. Tiap konsentrasi dan durasi kemudian dipaparkan dalam serum aktif (Fetal Bovine Serum/FBS) atau serum inaktif (FBS yang sudah dipanaskan pada suhu 65°C selama 30 menit untuk inaktivasi komplemen) pada suhu 37°C selama 2 jam. Jumlah koloni C. albicans pada Sabouraud Dextrose Agar (SDA) dihitung 2 hari kemudian. Prosedur yang sama dilakukan pada C. albicans strain ATCC 10231. Analisis data menggunakan uji one-way ANOVA dengan 0,05. Hasil: Pada kultur C. albicans 3 hari, jumlah koloni dalam serum aktif secara bermakna lebih rendah daripada dalam serum inaktif, baik dengan maupun tanpa paparan xylitol (p = 0.032). Peningkatan konsentrasi xylitol meningkatkan jumlah koloni C. albicans klinis dalam serum aktif, walaupun secara statistik tidak bermakna (p = 0.689). Hanya paparan xylitol 10% selama 7 hari yang meningkatkan jumlah koloni C. albicans secara bermakna (p = 0.034). Faktor serum tidak mempengaruhi jumlah koloni C. albicans usia 7 hari. (p = 0.404). Simpulan: Pemberian xylitol 1%, 5%, dan 10% selama 3 dan 7 hari tidak mempengaruhi efek inhibisi C. albicans oleh faktor serum. Efek inhibisi C. albicans oleh faktor serum hanya bermakna pada kultur usia 3 hari dan tidak terlihat pada kultur usia 7 hari.

Serum factor with antimicrobial effect like complement, could inhibit C. albicans growth. Xylitol is reported to inhibit the growth of C. albicans.

Objectives: Investigating the effect of 1%, 5%, 10% xylitol for 3 or 7 days on C. albicans resistance in serum in vitro, and investigating whether serum factor plays role in inhibiting the growth of C. albicans.

Methods: Identification of C. albicans taken from oral swab of candidiasis patient was conducted using CHROMagar, and confirmed by germ tube test. The cultures were serially diluted and inoculated in Sabouraud Dextrose Broth (SDB) contained 0% (control), 1%, 5%, or 10% xylitol and kept for 3 or 7 days. These inoculations were then exposed to either active or inactive serum (Fetal Bovine Serum heated in 65°C for 30 minutes to inactivate the complement) for 2 hours in 37°C. The Colony Forming Unit (CFU) of C. albicans in Sabouraud Dextrose Agar (SDA) were counted after 2 days. The same procedure was conducted for C. albicans ATCC 10231 strain. Data was analyzed using one-way ANOVA with 0.05.

Results: After 3 days cultured in media with or without xylitol, the CFU of C. albicans exposed to active serum were significantly lower than those exposed to inactive serum (p = 0.032). Increased concentration of xylitol lead to increased resistance of C. albicans in active serum, though it was not significant statistically (p = 0.689). Only 7 days exposure of 10% xylitol resulted in significantly higher growth of C. albicans (p = 0.034), but no significant difference on C. albicans CFU between in active or inactive serum (p = 0.404).

Conclusion: Exposure of 1%, 5%, or 10% xylitol for 3 or 7 days has no significant effect on C. albicans resistance in serum. The inhibition effect of serum factor to C. albicans growth was significant after 3 days, but not effective anymore after 7 days."
