"Biofilm adalah struktur kompleks tiga dimensi yang terdiri dari bakteri hidup dalam matriks ekstraselular atau excreted polymeric substance (EPS) yang mengandung polisakarida, asam nukleat dan protein. Infeksi yang diakibatkan biofilm sulit untuk dieradikasi, karena EPS pada biofilm dapat meningkatkan resistensi bakteri dan menghambat antibiotik mencapai bakteri tersebut. Biofilm dapat melekat pada alat-alat kesehatan seperti kanul trakeostomi.  Pembentukan kolonisasi bakteri biofilm pada kanul trakeostomi dapat menyebabkan inflamasi kronik yang memicu infeksi stoma dan saluran pernapasan bawah, serta pembentukan jaringan granulasi. Tujuan penelitian ini adalah untuk meningkatkan pengetahuan mengenai biofilm dan mikroba pembentuk biofilm, serta faktor risiko yang mempengaruhi pembentukannya. Penelitian ini menggunakan desain potong lintang, dilakukan di poliklinik THT FKUI-RSCM Dr. Cipto Mangunkusumo pada bulan Februari 2019 sampai dengan Agustus 2019 terhadap pasien yang terpasang kanul trakeostomi usia dewasa.

Biofilm is a three-dimensional complex structure consisting of living bacteria in an extracellular matrix or excreted polymeric substance (EPS) containing polysaccharides, nucleic acids and proteins. Infections caused by biofilms are difficult to eradicate, because EPS in biofilms can increase bacterial resistance and prevent antibiotics from reaching the bacteria. Biofilms can be attached to medical devices such as tracheostomy cannula. The formation of bacterial colonization of biofilms in tracheostomy cannulas can cause chronic inflammation that triggers stoma and lower respiratory tract infections, and the formation of granulation tissue. This study aimed to increase knowledge about biofilms and biofilm-forming microbes, and risk factors that influence its formation. This cross-sectional designs study, conducted at the ENT polyclinic FKUI-RSCM Dr. Cipto Mangunkusumo on February 2019 to August 2019 of adult patients with tracheostomy cannula.There was a statistically significant correlation between risk factors of comorbid disease with an increase of the biofilms formation in patients with tracheostomy cannula."

"Latar Belakang: Temulawak (Curcuma xanthorrhiza Roxb) merupakan tanaman herbal Indonesia yang telah diketahui memiliki efek antibakteri dan antijamur khususnya terhadap S. mutans dan C. albicans. Dalam rongga mulut, S. mutans dan C. albicans memiliki hubungan sinergis dalam pembentukan biofilm. Ikatan sinergis dual species dalam biofilm tersebut dapat meningkatkan resistensi terhadap agen antimikroba. Dalam pengembangan ekstrak etanol temulawak, diperlukan keamanan dan kualitas tanaman yang baik, yang dapat dilihat dari kemampuannya dalam mempertahankan stabilitas fisika, kimia, dan biologisnya dalam durasi dan temperatur penyimpanan yang berbeda. Tujuan: Menganalisis efek ekstrak etanol temulawak dalam mengeradikasi perkembangan biofilm single species dan dual species (S. mutans dan C. albicans), serta pengaruh durasi dan temperatur penyimpanan terhadap stabilitas biologis ekstrak etanol temulawak. Metode: Pemaparan ekstrak etanol temulawak pada biofilm single species dan dual species (S. mutans dan C. albicans) selama 6 jam untuk mencapai biofilm fase awal, dan dilakukan TPC dan MTT Assay. KEBM diuji dengan memaparkan ekstrak etanol temulawak pada biofilm usia 6 jam. Stabilitas biologis ekstrak dapat diamati melalui uji kontaminasi mikroba pada ekstrak etanol temulawak yang disimpan pada temperatur 4°C dan 28°C dan dilakukan pengujian setiap 2 minggu selama 4 minggu. Pengujian dilakukan dengan melakukan pengenceran ekstrak etanol temulawak yang ditumbuhkan pada medium Plate Count Agar (PCA) dan dilakukan perhitungan koloni atau Total Plate Count (TPC), yang kemudian dianalisis secara statistik menggunakan uji Mann-Whitney. Hasil: Ekstrak etanol temulawak memiliki nilai KEBM50 pada biofilm single species (S. mutans maupun C. albicans) pada fase awal sebesar 15%. Sedangkan pada dual species (S. mutans dan C. albicans) fase awal sebesar 25%. Kontaminasi mikroba yang terjadi masih berada di bawah batas produk farmasi non steril (<107 CFU/gr). Kesimpulan: Ekstrak etanol temulawak mampu mengeradikasi biofilm single species dan dual species (S. mutans dan C. albicans) pada fase awal. Diperlukan konsentrasi ekstrak etanol temulawak yang lebih tinggi untuk menghambat dan mengeradikasi biofilm dual species dibandingkan single species.

Background: Javanese turmeric (Curcuma xanthorrhiza Roxb) is an Indonesian native herbal plant which is known to have antibacterial and antifungal effects, especially against S. mutans and C. albicans. In the oral cavity, S. mutans and C. albicans have a synergistic relationship in the formation of biofilm. The synergistic bond of dual species in the biofilm can increase resistance to antimicrobial agents. In the development of Javanese ethanol extract, good safety and quality of the plant is needed, which can be seen from its ability to maintain its physical, chemical, and biological characteristics in different storage duration and temperatures. Objective: To analyze the effect of Javanese turmeric ethanol extract in eradicating the development of single species and dual species (S. mutans and C. albicans) biofilm, and the effect of storage duration and temperature on the biological characteristic of Javanese turmeric ethanol extract. Methods: Exposure of Javanese turmeric ethanol extract to single species and dual species (S. mutans and C. albicans) biofilm for 6 hours to achieve early phase, and measured by TPC and MTT Assay. MBEC was tested by exposing Javanese turmeric ethanol extract to a 6 hour old biofilm. Biological characteristic can be observed through microbial contamination test on Javanese ethanol extract stored at 4°C and 28°C and tested every 2 weeks for 4 weeks long. The test was carried out by diluting the Javanese turmeric ethanol extract grown on Plate Count Agar (PCA) medium and total plate count (TPC), then were statistically analyzed using the Mann-Whitney test. Results: MBEC50 of Javanese turmeric ethanol extract for single species (S. mutans as well as C. albicans) in early phase were 15%. And for dual species (S. mutans and C. albicans) in early phase were 25%. The microbial contamination that occurred was still below the limit for non-sterile pharmaceutical products (<107 CFU/gr) Conclusion: Javanese ethanol extract has the ability to eradicate single species and dual species (S. mutans and C. albicans) in the early phase. Higher concentrations of Javanese turmeric ethanol extract are required to eradicate dual species than single species biofilm. Javanese turmeric ethanol extract stored at 4°C and 28°C still maintained its biological characteristics even after 4 weeks of strorage."
