Abstract
Abstrak Selama ini diagnosa kandidiasis masih terbatas pada kultur darah standar. Metode konvensioanal dengan kultur mikrobiologi ini kurang sensitif, beberapa pasien kandidiasis mempunyai kultur darah negatif dan memerlukan waktu yang lama. Hal ini mendorong beberapa peneliti mencari metode alternatif diagnosa lainnya. Tujuan penelitian ini adalah untuk menentukan potensi ekstrak protein Candida albicans sebagai bioreseptor pada imunosensor untuk mendeteksi Candida albicans dan biofilmnya dalam darah pasien kandidiasis. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dengan tahapan sebagai berikut: (1) isolasi enzim dari cairan pencernaan bekicot; (2) ekstraksi protein Candida albicans melalui metode enzimatis dan mekanik dan (3) analisis ekstrak protein sebagai bioreseptor melalui immunodot assay. Hasil penelitian menunjukkan bahwa enzim bekicot memiliki kadar protein 1,35 mg/ml dan aktifitas spesifik 1,96 Unit/mg. Enzim ini mampu menghidrolisis dinding sel C. albicans dan dengan bantuan sonikasi menghasilkan ekstrak protein ekstrasel planktonik (PEP) dan biofilm (PEB), ekstrak protein intrasel plantonik (PIP) dan biofilm (PIB), dengan kadar protein masing-masing 1,44; 1,29; 1,29 dan 1,21 mg/ml. Ekstrak protein PIB bersifat antigenik terhadap antibody anti-Candida (kontrol positif) dengan memberikan spot berwarna merah pada immunodot assay. Immunodot assay dapat membedakan serum kontrol negatif (orang sehat) dan kontrol positif dengan menggunakan antigen 1 ng/nl dan 50 nl serum. Kata Kunci : Candida albicans, kandidiasis , biofilm, pemeriksaan immunodot THE POTENCY OF Candida albicans PROTEIN EXTRACT AS BIORESEPTOR ON IMMUNOCENCOR TO DIAGNOSE CANDIDIASIS Abstract So far, diagnosing on candidiasis has still been limited in standard blood culture. The traditional method of this microbiology culture is less sensitive, many patients withJurnal “Ilmiah Kedokteran” Volume 3 Nomer 2 Edisi Oktober 2014, hal. 26-39 27 candidasis infection have negative blood culture, and need a long time. This case encourage many researchers to use another alternative methode to diagnose. The purpose of this research is to examine the potency of Candida albicans protein extract as bioreseptor on immunocencor to detect Candida albicans and its biofilm in the blood of candidiasis patients. The research method which is used is descriptive with the following steps : (1) isolating enzim from the liquid of digestive gland of snail (Achatina fulica); (2) extraction of protein candida albicans through enzimatis and mechanic methods and (3) Analyzing the protein extract as bioreseptor through immunodot assay. The research result shows that the snail enzyme has the protein content 1.35 mg/ml and the specific activity 1.96 unit/mg. This snail enzyme can hydrolyze the cell wall of Candidia albicans and, with the help oh sonication, produce extract of planktonic extracel protein (PEP) and biofilm (PEB), extract of planktonic intracell protein (PIP), and biofilm (PIB), with each protein content 1.44; 1.29; 1.29 and 1.21 mg/ml. The characeristic of biofilm intracell protein (PIB) is antigenic on antibody anti-candida (positive control) with giving red spot on immunodot assay. Immunodot assay can distinguish negative control serum (health man) and positive Candidiasis control by using antigen 1 ng/nl and 50nl serum. Keywords: Candida albicans, candidiasis, biofilm, immunodot assay
