AbstractDengue virus is highly pathogenic in humans and spreads rapidly through Aedes aegypti and Aedes albopictus mosquitoes. More than half a billion people from 100 countries in the world are at serious risk of dengue virus infection. The purpose of this study was to prove the existence of transovarial transmission of dengue virus in Aedes aegypti mosquitoes with a transovarial transmission index (TTI) in endemic areas in Pontianak, West Kalimantan. This research method is descriptive observational with a cross-sectional study. The results of the Microscopic Examination of Head Squash Preparations on the Aedes aegypti mosquito, showed the Transovarial Transmission Index in Batulayang Village was 39.60% higher, compared to Sungai Jawi Village, which was 29.30%, but both were still lower than ITT in 2012. The results of the Aedes mosquito examination aegypti using the Polymerase Chain Reaction Transcription Reaction (PCR-TR) method found the dengue virus strain. The conclusion of this study proves that the transovarial transmission of dengue virus in Aedes aegypti mosquitoes in Sungai Jawi Village is 29.30% lower than in Batulayang Village by 39.60%, and the dengue virus serotype, DENV-3, has been found.Keywords: transovarial transmission; dengue virus; Aedes aegypti AbstrakVirus Dengue sangat patogen pada manusia dan menyebar dengan cepat melalui nyamuk Aedes aegypti dan Aedes albopictus. Lebih dari setengah miliar penduduk dari 100 negara di dunia berada pada risiko serius infeksi virus dengue. Tujuan dari penelitian ini adalah untuk membuktikan adanya penularan virus dengue transovarial pada nyamuk Aedes aegypti dengan indeks transmisi transovarial (TTI) di daerah Endemis di Pontianak, Kalimantan Barat. Metode penelitian ini adalah deskriptif observasional dengan studi potong lintang. Hasil Pemeriksaan Mikroskopis Sediaan Head Squash pada nyamuk Aedes aegypti, menunjukan Indeks Transmisi Transovarial pada Kelurahan Batulayang lebih tinggi yaitu 39,60%, dibandingkan dengan Kelurahan Sungai Jawi yaitu 29,30%, tetapi keduanya masih lebih rendah dibandingkan ITT pada Tahun 2012. Hasil pemeriksaan nyamuk Aedes aegypti dengan metode Polymerase Chain Reaction Transcription Reaction(PCR-TR) ditemukan strain virus Dengue-3. Kesimpulan penelitian ini membuktikan adanya transmisi transovarial virus dengue pada nyamuk Aedes aegypti di Kelurahan Sungai Jawi sebesar 29,30% lebih rendah dibandingkan di kelurahan Batulayang sebesar 39,60%, serta berhasil ditemukan serotipe virus Dengue yaitu DENV-3.Kata Kunci : transmisi transovarial; virus dengue; Aedes aegypti

The <em>Dengue virus</em> is the main arbovirus that affects man in terms of morbidity and mortality. The detection of the virus is very important for epidemiological surveillance, so here we propose to standardize and compare the immunodot blot (IDB) and multiplex reverse transcriptase-polymerase chain reaction (M-RT-PCR) techniques to detect and characterize the dengue virus (DENV) serotypes in samples of <em>Aedes aegypti</em> larvae. Thus, the IDB and M-RT-PCR techniques were standardized using macerated samples of larvae collected in nature. The use of monoclonal antibodies in IDB has not shown great results, but DENV detection through this method was possible using polyclonal antibodies. The distinction of serotypes 1, 2 and 3 was carried out by M-RT-PCR.

The present study was aimed to investigate the circulation of four dengue virus (DENV) serotypes in Makkah, Western Saudi Arabia. Blood samples were collected from 25 dengue fever-suspected patients and were subjected to molecular typing for DENV-1, DENV-2, DENV-3, and DENV-4 serotypes of dengue virus, by reverse transcription polymerase chain reaction (RT-PCR), using six sets of primers. Of the 25 samples, only six samples (24%) were found to be positive for dengue virus infection. The prevalence of DENV-1 was higher (50% of DENV-positive samples), as compared to DENV-2 (33.3%) and DENV-3 (16.6%) serotypes. The fourth serotype, DENV-4, was not detected in any of the DENV-positive samples. Although Makkah is considered endemic to dengue fever, we observed low prevalence of dengue virus in the city, which may be attributed to various factors. Nonetheless, the results presented herein confirm the circulation of DENV serotypes in the Western region of Saudi Arabia. To the best of our knowledge, the current study so far is the first report demonstrating the prevalence of the DENV-1 serotype in the city Makkah, Saudi Arabia.

Aims: This study was set to optimize conditions for real time reverse transcriptase polymerase chain reaction (RT-PCR) for detection of dengue virus by using rapid and simple nucleic acid extraction method. Methodology: One step and two step real time RT-PCR were evaluated in different PCR thermocyclers. Extraction of viral RNA was done by using a simple boom method. Results: The real time RT-PCR technique was successfully optimized using simple and rapid method for purification of nucleic acid, ‘boom method’. The technique works better when performed in a two-step procedure and can works well with all range of real time PCR machines. The optimized real time RT-PCR used in the present study is a valuable and reliable technique for routine diagnosis of dengue. Further investigation on the cost effectiveness in adopting this technique for routine screening and monitoring of the dengue infection should be done.
