Abstract

Latar belakang: Madu Apis dorsata memiliki aktivitas untuk menghambat pembentukan biofilm Candida albicans . Madu mengandung fenolik, steroid, tannin dan flavonoid. Dimana flavonoid merupakan salah satu kelas dari keluarga fenolik (setengah dari jumlah total senyawa fenolik) berfungsi untuk menghambat pembentukan biofilm Candida albicans . Tujuan: penelitian ini bertujuan untuk mengetahui aktivitas antibiofilm madu Apis dorsata terhadap biofilm Candida albicans . Metode: Sampel yang digunakan berupa madu Apis dorsata yang diperoleh dari Gunung Mutis Nusa Tenggara Timur. Sampel madu dilarutkan dalam media RPMI 1640 dengan konsentrasi larutan konsentrasi 50%, 25%, 12,5%, 6,25%, dan 3,125%. Uji aktivitas antibiofilm madu terhadap biofilm Candida albicans  dilakukan dengan metode Mikrotiter plate menggunakan ELISA reader.  Hasil: Hasil penelitian menunjukkan bahwa semua konsentrasi madu memiliki aktivitas menghambat pembentukan biofilm Candida albicans  dengan penghambatan terbesar konsentrasi madu 50% sebesar 69,78%. Penelitian ini menunjukkan bahwa madu Apis dorsata dari Gunung Mutis NTT secara kuat menghambat pembentukan biofilm Candida albicans . Efektivitas ini bersifat dosis-dependen, di mana konsentrasi madu 50% memberikan tingkat penghambatan tertinggi sebesar 69,78%. Kesimpulan: Dengan demikian, madu ini patut dipertimbangkan sebagai sumber agen antibiofilm alami yang potensial, berkat kandungan senyawa fenolik dan flavonoidnya.

Abstract

Escherichia coli is one of the gram-negative bacteria that produces the Extended Spectrum Beta-Lactamase (ESBL) enzyme and has a role in resistance to the beta-lactam group. The presence of E. coli bacteria that produce ESBL in food, especially in fish such as milkfish (Chanos chanos) poses a potential source of the spread of antimicrobial resistance (AMR) in humans. This study aims to determine the prevalence of ESBL-producing E. coli in the intestinal flora of milkfish sold in traditional markets in Surabaya City. This study used a descriptive observational method with a cross-sectional approach. There were 50 samples of milkfish intestines taken from several stalls in traditional markets randomly. Identification of E. coli bacteria by planting in MacConkey media with 4 µL/ml cefotaxime followed by the Double Disk Synergy Test (DDST). Of the 50 milkfish intestine samples used, 34 (68%) samples showed positive results for ESBL-producing E. coli. The high prevalence may indicate that the potential for the spread of antimicrobial resistance through the food chain, food hygiene management and controlling the use of antibiotics in fish farming need serious attention.

Abstract

Candida albicans infection is a serious health concern, particularly in immunocompromised individuals, due to its ability to form biofilms that are resistant to conventional antifungal therapies. Curcuma xanthorrhiza Roxb. (temulawak) possesses antifungal properties; however, its effectiveness is limited by poor solubility and bioavailability. Nanoemulsion formulation offers a promising strategy to enhance the penetration of active compounds. This study aimed to develop and evaluate the effectiveness of temulawak nanoemulsion as an antibiofilm agent against multidrug-resistant (MDR) C. albicans. Using a post-test control group only design, the antibiofilm assay was conducted via the microtiter plate method and analyzed based on Optical Density (OD) measurements. The results showed that temulawak nanoemulsion significantly reduced biofilm formation, with an 89% reduction in OD at the 100% concentration. These findings support the potential use of temulawak nanoemulsion as an alternative therapeutic strategy for Candida albicans infections, particularly those involving drug-resistant biofilms.

Abstract

Antimicrobial resistance (AMR) has become a serious global health issue, affecting both humans and pets. Cats, which frequently interact closely with humans, can serve as reservoirs of resistant Escherichia coli. This study aimed to assess the prevalence of ESBL-producing Escherichia coli in the intestinal flora of pet cats in Balongbendo, Sidoarjo, applying a One Health approach to explore the transmission interface between animals, humans, and the environment.A descriptive observational study with a cross-sectional design was conducted. A total of 50 fecal samples were collected by simple random sampling from pet cats in RW 01, Desa Jabaran, Sidoarjo (January–February 2025). Samples were incubated on MacConkey agar enriched with 4 µg/mL cefotaxime for screening ESBL, and confirmation was conducted utilizing the Double Disk Synergy Test (DDST). Prevalence was determined as the ratio of positive isolates to the overall total . The results showed that 20 of 50 samples (40%) were positive for ESBL-producing Escherichia coli. The highest prevalence was found in Area 1 (60%), which was characterized by poor sanitation and high population density. This indicates widespread ESBL-producing Escherichia coli in domestic animals and underscores the risk of cross-transmission to humans. Therefore, educating animal owners, monitoring antibiotics, and ensuring environmental sanitation are crucial for preventing cross-transmission to humans.
