Abstract

Dengue Hemorrhagic Fever (DHF) is a global health problem in tropical and subtropical regions, as well as endemic in110 countries around the world. Indonesia is one of the largest countries in the region of endemic dengue. In Indonesia, dengue virus infection has become a contagious disease that was very important and was reported in 1968. Many molecular epidemiological approaches have been developed to look for factor that has been assumed as the cause of the increase of prevalence dengue virus infection in the world. The aim of this study is for the detection and determination of serotype of dengue virus in Surabaya. The method used was the technique of Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and Polymerase Chain Reaction (PCR) with specific primers for dengue virus. Samples suspected DHF patients were obtained from various health center and hospital in Surabaya. Results of this research detected negative result for dengue virus in all samples of patients suspected DHF. Negative results caused by dengue virus titers in serum samples of patients who had been dropped due to long storage time and taken after the third day of fever in early period.

Abstract

Dengue virus (DENV) serotypes DENV-1 to DENV-4 are enveloped viruses that belong to the genus Flavivirus of the Flaviviridae. Dengue vaccine or antiviral has not yet been clinically approved for humans, even though there have been great efforts toward this end. Antiviral activity against DENV is needed to develop to be an alternative drug for DENV virus. Cobalt(II) chloride have been used in the treatment and prevention of diseases of humans since ancient times. The aim of this study is to investigate the antiviral effects and Cytotoxicity of Cobalt(II) chloride. This compound was further investigated for its inhibitory effect on the replication of DENV-1 in Vero cells. Antiviral activity and Cytotoxicity measured by WST-1 assay. The IC50 value of the Cobalt(II) chloride for DENV-1 was 0.38 μg/ml. The cytotoxicity of Cobalt(II) chloride to Vero cell suggest that the CC50 value was 2.91 µg/ml The results of this study demonstrate the anti-dengue serotype 1 inhibitory activity of Cobalt(II) chloride was a high toxic compound.
