Demam berdarah dengue merupakan salah satu penyalcit wabah di didunia yang telah merenggut banyak nyawa. Pada tahun 2004 tetjadi wabah demam berdarah dengue di Jakarta dengan lebih dati 10.000 kasus dengan angka kematian dilaporkan sebanyak 603 orang dengan kasus infeksi serotipo virus dengue terbanyak adalah serotipe 3. Penelitian ini menggueakan metode PCR. Pada penelitian ini dilakukan analisls variasi genetik genE, NSI, dan NS3 dari virus dengue tipe 3 yang diisolasi dari pasien dengan manifestasi klinis yang berbeda Strain DS2207 (DD), DS4607 (DBD), DSA0206 (DSS) yang diisolasi dari kasus dengue 2006-2007 dan dibandingkan dengan 12 strain yang berasal dati Indonesia, Thailand, Tahiti, Venezuela, Malaysia. Homologi etikleotida genE berkisar antara 92,4- 100 % sedangkan asam amino E 97- 100%. Homologi nukleotida gen NSI berkisar antara 93,4- 100 %, sedangkan asam amino NSl 97,2- 100%. Homologi nukleotida gen NS3 berkisar antara 92,8 - 99,5 % sedangkan asam amino NS3 98,2-99,7 % terdapat variasi pada ketiga gen, tapi belum ditemukan adanya perbedaan spesifik dari manifestasi klinis yang ditimbulkan.
Dengue hemorrhagic fever is one of the epidemically disease that widely spread and has taken many lives. In the year of 2004, the epidemic of dengue hemorrhagic fever occurred in Jakarta with more than 10,000 number of cases, and 603 reported to death, where stereotype 3 showed as the most dengue virus stereotype infection cases. This research used the PCR (polymerase chain reaction) method, along with an analysis in genetically variety of E, NSI, and NS3 Gene of isolated Type 3 Dengue Virus (from the patient with any different clinical symptom). Strain of DS2207 (Dengue fever), 084607 (Dengue hemorrhagic fever), DSA0206 (Dengue shock syndrome) has been isolated of the 2006-2007 dengue cases, and compared' with 12 strain from Indonesia, Thailand, Tahiti, Venezuela, and Malaysia. Nucleotide homology of the E gene is somewhere around 92,4% up to 100%, with theE aroino acid reached 97% up to 100%. Nucleotide homology of the NSl gene is somewhere around 93,4% up to 100%, with the NSI amino acid reached 92,2 % up to 100 % nucleotide homology of the NS3 gene is somewhere around 92,8 % up to 99,5 % with the NS3 amino acid reached 98,2 % up to 99,7 %. There were also variety of those genes, without any specipic differences among different manifestations. |
