Cara sitasi: Rahayu WP, Rinati R, Nurjanah S, Nurwitri CC. 2016. Identifikasi Listeria monocytogenes pada kerang hijau dan kerang darah. Jurnal Pengolahan Hasil Perikanan Indonesia 19(3): 329-338. AbstrakKerang hijau (Perna viridis) dan kerang darah (Anadara granosa) merupakan salah satu sumber protein hewani yang banyak dibudidaya di Indonesia karena harganya yang relatif terjangkau. Penelitian ini bertujuan untuk mengidentifikasi keberadaan Listeria monocytogenes pada 27 sampel kerang hijau dan 3 sampel kerang darah di Bogor menggunakan real-time Polymerase Chain Reaction (real-time PCR) dan metode biokimiawi. Gen yang dijadikan target untuk amplifikasi pada real-time PCR merupakan gen hlyA karena gen ini merupakan gen penentu virulensi yang menghasilkan listeriolysin O. Primer yang digunakan pada penelitian ini adalah primer forward DG69 (GTG CCG CCA AGA AAA GGT TA) dan primer reverse DG74 (CGC CAC ACT TGA GAT AT) serta sinyal fluorescence menggunakan SYBR Green I. Hasil analisis menggunakan real-time PCR menunjukkan hasil negatif Listeria monocytogenes pada semua sampel. Sedangkan hasil analisis menggunakan metode biokimiawi, menemukan 1 dari 30 sampel teridentifikasi sebagai Listeria welshimeri.Kata kunci: gen hlyA, kerang, Listeria monocytogenes, Listeria spp., real-time PCR AbstractGreen mussel (Perna viridis) and cockle shell (Anadara granosa) are one of many sources of animal protein which is many cultivated in Indonesia because their price is relatively affordable. This study was conducted to identify the presence of Listeria monocytogenes in 27 samples of green mussels and 3 samples of cockle shells using real-time Polymerase Chain Reaction (real-time PCR) and biochemical methods. The target gene for amplification in real-time PCR was an hlyA gene because this gene was a determinant of virulence genes that produce listeriolysin O. Primers used in this study were forward primer DG69 (GTG CCG GGT AAA AGA CCA TA) and reverse primer DG74 (CGC CAC TGA GAT ACT AT) and fluorescence signals indicator using SYBR Green I. The results of analysis using real-time PCR were negative Listeria monocytogenes in all samples, while using biochemical methods there was one of 30 samples contaminated by Listeria welshimeri.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
