Detection of attaching and effacing virulence gene of E. coli
<p>Abstrak<br />Latar belakang: Bakteri Escherichia coli (E. coli) ada yang telah bermutasi menjadi patogen yang menimbulkan berbagai penyakit seperti hemorrhagic colitis (HC), hemolytic uremic syndrome (HUS), sepsis, pnemonia, neonatal meningitis, dan infeksi saluran kemih. Mutasi terja...

Mutasi terjadi karena bakteri ini menerima transfer gen yang virulen dari bakteri lain yang hidup di sekitarnya. E. coli yang biasanya hidup normal di dalam usus manusia telah beradaptasi sehingga bisa hidup di tanah, makanan, dan saluran kemih. Penelitian ini mendeteksi gene yang virulen pada DNA isolat E. coli. Metode: Untuk deteksi E. coli yang virulen pada penelitian ini digunakan metode Real-time PCR dengan mencocokkan hasil sekuensing dengan sekuens E. coli virulen yang telah di publikasikan sebagai rujukan. Hasil: Sekuens RT PCR menggambarkan DNA gen eae pada BLAST mempunyai kesesuaian dengan rujukan segmen E. coli yang virulen. Dari sampel yang berasal dari E. coli di sekitar perairan lingkungan didapatkan gen Eae sebagai gen yang menyebabkan E. coli menjadi virulen sebesar 7,3%.
