Resistansi Escherichia coli asal feses sapi di wilayah Bogor terhadap antimikrob
Abstract
Resistansi bakteri terhadap antimikrob telah menjadi permasalahan global. Pengujian resistansi antimikrob bakteri dari hewan penting dilakukan terutama dengan adanya resistansi antimikrob pada manusia yang diduga bersumber pada ternak. Tujuan penelitian ini adalah untuk menganalisis gambaran resistansi Escherichia coli (E. coli) yang diisolasi dari feses sapi terhadap berbagai antimikrob, yaitu aztreonam, basitrasin, sefpodoksim, enrofloksasin, fosfomisin, gentamisin, dan kloramfenikol. Uji resistansi antimikrob dilakukan menggunakan metode difusi cakram Kirby-Bauer. Hasil uji diinterpretasi menurut Clinical and Laboratory Standards Institute (CLSI). Isolat E. coli asal feses sapi yang diperiksa resistan terhadap aztreonam (40%), sefpodoksim (40%), fosfomisin (50%), basitrasin (100%), dan gentamisin (10%). Isolat E. coli sebanyak 30% memiliki kepekaan intermediat terhadap fosfomisin. Seluruh isolat sensitif terhadap kloramfenikol (100%), dan sebagian besar sensitif terhadap enrofloksasin (90%) dan gentamisin (90%). Isolat E. coli yang resistan terhadap aztreonam dan sefpodoksim diduga berfenotip extended spectrum β-lactamase (ESBL). Pengobatan infeksi E. coli pada sapi harus memperhatikan gambaran resistansi isolat terhadap antimikrob.
