Abstract
DETEKSI GEN BlaTEM PADA ISOLAT BAKTERI DARI SAMPEL URINE PASIEN INFEKSI SALURAN KEMIH ABSTRAK Latar belakang: Infeksi Saluran Kemih (ISK) merupakan infeksi bakteri tersering di dunia dengan angka morbiditas tinggi. Meningkatnya resistensi antibiotik β-laktam akibat produksi enzim ESBL yang disandi gen blaTEM menjadi tantangan utama penanganan ISK, terutama pada Enterobacteriaceae. Tujuan: Penelitian ini bertujuan mendeteksi keberadaan gen blaTEM pada isolat Enterobacteriaceae dari sampel urin pasien ISK. Metode: Penelitian deskriptif observasional dengan pendekatan cross-sectional. Sampel berupa isolat Enterobacteriaceae dari urin pasien ISK di RSUD Wangaya Denpasar. Isolasi bakteri dilakukan kultur pada media MacConkey Agar. Deteksi gen blaTEM menggunakan metode PCR dengan primer spesifik (target ±850 bp). Ekstraksi DNA menggunakan metode PCIA. Hasil: Dari 28 isolat Enterobacteriaceae yang diuji, 17 sampel (60,7%) menunjukkan pita DNA pada ukuran ±850 bp yang mengindikasikan keberadaan gen blaTEM. Kontrol positif menunjukkan pita jelas pada ukuran target, sedangkan kontrol negatif tidak menunjukkan amplifikasi, menandakan tidak ada kontaminasi dan proses PCR valid. Kesimpulan: Gen blaTEM berhasil dideteksi pada isolat Enterobacteriaceae dari sampel urin pasien ISK, sehingga metode PCR terbukti efektif untuk deteksi gen resistensi tersebut pada isolat klinis. Kata kunci: blaTEM, Enterobacteriaceae, ISK, PCR DETECTION OF BlaTEM GENE IN BACTERIAL ISOLATES FROM URINE SAMPLES OF URINARY TRACT INFECTION PATIENTS ABSTRACT Background: Urinary Tract Infection (UTI) is one of the most common bacterial infections worldwide with high morbidity rates. The increasing resistance to β-lactam antibiotics due to ESBL enzyme production encoded by the blaTEM gene is a major challenge in UTI management, particularly in Enterobacteriaceae. Objective: This study aimed to detect the blaTEM gene in Enterobacteriaceae isolates from urine samples of UTI patients. Method: This descriptive observational study used a cross-sectional approach. Samples were Enterobacteriaceae isolates from urine of UTI patients at Wangaya Hospital Denpasar. Bacterial isolation was performed by culture on MacConkey Agar. Detection of the blaTEM gene used PCR with specific primers (target ±850 bp). DNA extraction used the PCIA method. Results: Of 28 Enterobacteriaceae isolates tested, 17 samples (60.7%) showed DNA bands at ±850 bp, indicating the presence of the blaTEM gene. The positive control showed a clear band at the target size, while the negative control showed no amplification, indicating no contamination and valid PCR process. Conclusion: The blaTEM gene was successfully detected in Enterobacteriaceae isolates from urine samples of UTI patients. Therefore, the PCR method is proven effective for detecting this resistance gene in clinical isolates. Keywords: blaTEM, Enterobacteriaceae, Urinary Tract Infection, PCR
