andida spp. merupakan patogen nosokomial yang paling umum diisolasi di antara spesies ragi dan menyebabkan mortalitas yang tinggi. Kontaminasi Candida yang resistan antifungal banyak ditemukan pada berbagai permukaan di lingkungan rumah sakit, sehingga meningkatkan kemungkinan transmisinya dari lingkungan. Penelitian ini bertujuan untuk mengetahui gambaran kontaminasi, efektivitas desinfeksi, serta karakteristik kepekaan Candida spp. terhadap antifungal. Penelitian dilakukan dengan pengambilan sampel permukaan di ruang perawatan intensif rumah sakit rujukan di Jakarta pada area high touch surfaces. Sampel dibiakkan pada medium CHROMagar Candida™, kemudian koloni ragi dihitung untuk mengetahui pengaruh disinfektan. Identifikasi spesies dilakukan menggunakan VITEK, kemudian dilanjutkan dengan PCR dan sekuensing dengan target regio ITS, serta dilakukan analisis filogenetik. Profil kepekaan Candida spp. dianalisis menggunakan VITEK. Berdasarkan hasil dijumpai 7 spesies Candida yang mengontaminasi permukaan yang didominasi oleh C. haemulonii. Hasil uji kepekaan antifungal menunjukkan bahwa seluruh isolat C. haemulonii resistan terhadap amphotericin B, dan satu isolat C. glabrata resistan terhadap caspofungin. Berdasarkan analisis efektivitas disinfektan, terdapat penurunan jumlah koloni Candida spp. sesudah prosedur desinfeksi yang menunjukkan bahwa prosedur desinfeksi sudah cukup efektif. Sebagai kesimpulan, C. haemulonii merupakan kontaminan utama pada permukaan yang resistan amphotericin B. Adapun tindakan desinfeksi sudah efektif namun cara melakukan desinfeksi perlu diperbaiki.

Candida spp. is the most common nosocomial pathogen isolated among yeast species with a high mortality rate. Antifungal-resistant Candida contamination has been found on various surfaces in the hospital environment, thus increasing the possibility of transmission. This study was conducted to determine Candida’s contamination profile, disinfection efficacy, and antifungal susceptibility features. Surface samples were collected in the intensive care unit ofreferral hospital in Jakarta, at the high touch surfaces area. The samples were then cultured on CHROMagar™ Candida, then yeast colonies were counted to determine the disinfectant efficacy. Species were identified using VITEK, PCR and sequencing targeting the ITS region, followed by phylogenetic analysis. Susceptibility characteristic of Candida spp. were analyzed using VITEK. The surface was contaminated by seven species of Candida, with C. haemuloni predominating. All C. haemulonii isolates were resistant to amphotericin B, and one C. glabrata isolate was resistant to caspofungin. The disinfectant efficacy analysis showed that there was a decrease in the number of Candida spp. after disinfection treatment, indicating that the disinfectant is quite effective. In summary, C. haemulonii is the main contaminant on surfaces that are resistant to amphotericin B. Although the disinfection techniques have been effective, they still require improvement
