The avian influenza (AI) H5N1 viruses have caused nearly 600 fatal cases in the world since 2003. The H5N1 AI virus is still circulating in wild birds and domestic. One of the known of AI virus pathogenicity is the ability of the nonstructural protein (NS1 and NS2) to induce cytokine storm. Mutations of the NS1 and NS2 proteins may aggravate infections. Genetic sequences of NS gene that enco…
The epidemic arising out of H5N1 virus infection causes death case and material loss. Mutation of H5N1 virus that signify the increase of pathogenicity and change of dispersal of host response can be used to reference for early warning system of epidemic caused of avian influenza virus. The objective of this research is to obtain information related to molecular markers of pathogenicity of …
Background: Influenza A virus infection can cause pandemic influenza worldwide. The outbreak of the H1N1 virus occurred in Indonesia in April 2009. A total of 1892 suspected cases of H1N1 were reported between April and the end of December 2009. From 1892 suspected cases, there were only 809 confirmed infected by the H1N1 virus. Since the virus is a new strain, we wanted to know how many cases …
In the 20th century, influenza virus A infections caused the pandemic severe respiratory illness in humans, some of the cases were fatal. Therefore, it is important for us to know the transmission mechanism and factors that can affect the virulence of influenza viruses. Virulence of influenza virus in birds, mammals and humans is determined by its ability to inflict damage to host cells caused …
Background:H5N1 Avian Influenza virus is expected to continue to mutate, potentially increasing the capacity to jump the species barrier, and can be easily transmitted between humans. This study aimed to analyze the genetic dynamics of the NS1 gene and to recognize markers of virulence in VAI H5N1 NS1 gene sequences from Balinese poultry. Methods:The method used was isolation of RNA, NS1 gen…
