Abstract

In Indonesia, data on the phenotype of AI virus subtype H5N1 is very limited, due to the facilities for such testingshould be performed in a laboratory Biosafety level III. Additionally influenza virus has a high error rate duringtranscription of their genome has low RNA polymerase. High error rates generate quasispecies. In this study, wedid some H5N1 viruses infection with different genetic variations and conducted DNA sequencing in severalorgans. To determine the possible emergence detection of quasispecies in different organs and until the virus wasexcreted. We tested the hypothesis that the quasispecies might arise from virus that was infected to theexperimental animals. The results of this study showed that the AI virus subtype H5N1 had different phenotypes inanimal depending on their genetic character. AI virus subtype H5N1 killed chickens within 48-72 hoursdepending on the genetic character of the virus. New AI viruses of subtype H5N1 caused more severe organdamage severe than the character of the old AI viruses. Adaptation of virus in each organ also proved that the viruslikely create variations/quasispecies, which was different from the viral origin.Keywords: Phenotypes, avian influenza, H5N1, genetic character, quasispecies

ABSTRACTGenetic Mapping of Indonesian Avian Influenza Viruses 2007.Department of agricultureimplements vaccination as one a tool to control of avian influenza disease. The vaccinationprogram use virus seed such as H5N1, H5N2 and H5N9. Such as vaccination program for otherdiseases, avian influenza vaccine program have lack implementation in the field. In 2007,department of agriculture evaluated the AI vaccination program such as the master seedvaccine that can be used. Result of the evaluation showed that 11 of AI vaccines that weredistributed in Indonesia did not give protection more than 60% to Indonesian isolates in 2006(A/Ck/Pwt-Wij/06). From this point and many AI cases in the field in 2007, the aim of thisstudy was to conduct genetic diversity of avian influenza viruses which have circulated inIndonesia region. We used virus isolation for propagate the viruses, RT-PCR for identificationand DNA sequencing on HA1 region to analysis genetic diversity for genetic mapping anduseful for master seed candidate. The result of the study showed that there were 6 group ofgenetic diversity in 2007; Isolates from group 1, 5 and 6 can be used for AI vaccine candidate.Key words: genetic mapping, genetic diversity and avian influenza viruses

Abstract

ABSTRACTStatus of avian influenza virus subtype H5N1 in Indonesia until 2014 is still endemic in poultry and recorded, there were two types clade of circulating H5N1 namely clade 2.1.3 and the new introduction of lade 2.3.2 since the end of 2012. Both of the clade of avian influenza viruses subtype H5N1 (clade 2.1.3 and 2.3.2) caused the the  AI vaccination program to control of AI in poultry needs to be evaluated.  In this study, we developed a bivalent AI vaccine (which contains clade 2.1.3 and 2.3.2 viruses as a seed vaccine) that   adapted with  the circulation of AI viruses in the field. Result of the study showed that the bivalent vaccine which developed in this study has good efficacy that was challanged with both of AI clade AI and proven to reduce shedding / viral contamination to the environment. It is expected that  the development of bivalent H5N1 vaccine will increase the effectiveness and efficacy of vaccination programs to control highly pathogenic avian influenza disease in Indonesia. Keywords : avian influenza virus, clade, vaccine, bivalent

Abstract

ABSTRACTThe Newcastle Disease (ND) virus causes the most important disease in chicken, and very contagiuos in poultry in many countries. In Indonesia the Newcastle Disease or is called tetelo became endemic in chicken currently, the ND virus of genotype VII caused morbidity 100% and mortality 80% in chicken. The fusion and haemaglutinin-neuraminidase protein are involved in adhesion to the surface of hert cells to antibodies. HN and F protein induced by the ND vaccines have neutralizing effects. The aim of this study was to compare the antibody level and protection of several ND vaccine genotypes (genotype I, II, VI and VII) in chicken against ND virus chicken / Indonesia/GTT/11 genotype VII. Our result showed that all genotype ND vaccines (I, II, VI dan VII) produce 100% protection in chicken from clinical and mortality, but the challenge virus excretion in chickens vaccinated with ND vaccine VII genotypes were significantly different (p <0.05) to other groups. Response of antibody in chicken vaccinated ND genotype VII show highest mean titer (GMT 122) compered other ND vaccine. In onclusion, the ND virus chicken/Indonesia/ GTT/11 genotype VII is good to be used as inactive vaccine seed, which appropriate to the field virus circulating at this time.Keywords: virus, Newcastle Disease, genotype, vaccine

Abstract

The avian influenza H5N1 virus circulation in 2010 : Genetic Drift Like Virus A/Chicken/West Java/Pwt-Wij/2006 was found in several districts of Sumatra and Java. Until 2011, the H5N1 subtype of AI virus is still circulating in many parts of Indonesia. The discovery of the AI viruses which have undergone genetic drift since 2006 until now requires serious attention from the government in terms of AI disease control, the surveillance and monitoring of virus circulation and execution of genetic mapping to determine the genetic character of the AI virus at the molecular level, especially on the surface of glycoproteins (HA and NA protein).This information is needed to determine the diversity and character of the AI virus in Indonesia. Genetic data are used to evaluate the strategy to control AI in Indonesia, such as vaccination and the vaccine seed used and determine the extent of AI virus mutation in Indonesia has beenmutated. This study conducted by monitoring of the AI virus circulation throughout 2010. The methods used were AI virus isolation, RT-PCR, sequencing of genes coding for viral surface and the prediction of three-dimensional analysis to determine the location of virusmutation. The results of this study showed that most of the AI virus subtype H5N1, which was isolated during the year 2010, showed similar mutations to the genetic drift virus in 2006, A /Ck/West Java/Pwt-Wij/2006. The viruses were characterized by the presence of 18-19 amino acid substitutions at the level of the HA protein. On the NA protein level, there is a single mutation which was buried in the NA molecule. This mutation probably did not influence for NA activity. Genetic mapping of AI virus subtype H5N1 in 2010 showed that the viral genetic driftas the mutan virus A/Ck/West Java/Pwt-Wij/2006 have circulated not only in West Jawa alone but has been found on the island of Sumatra, Banten, West Jawa and East Jawa.Keywords: Circulation, avian influenza H5N1 virus, genetic drift

Abstract

Infectious Bursal Disease (IBD), also known as Gumboro disease, is an acute, highly contagious disease that infects chickens and causes a high mortality rate of up to 100% in young animals. The disease is caused by Infectious Bursal Disease Virus (IBDV) of the genus Avibirnavirus, family Birnaviridae. The disease has been reported in Indonesia since 1976, and management strategies for the disease, such as vaccination, have been applied to prevent and control outbreaks in poultry farms. In this study, we conducted the detection of the disease in chickens from a farm in West Java with a mortality rate of 80%. Chickens showing clinical signs, such as sudden death, anorexia, watery diarrhea, and ruffled feathers, were necropsied, and organ samples, including the bursa Fabricius, brain, and spleen, were collected. The samples were then tested using Reverse-Transcriptase Polymerase Chain Reaction (RT-PCR) to confirm the diagnosis of IBD. Positive results were obtained in this study, highlighting the need for improved biosecurity in poultry farms in Indonesia. These results also provided a basis for further research on viral characterization to develop detection kits or vaccines for IBD using local isolates from the field in Indonesia.

Abstract

This study aimed to determine the ability of highly pathogenic avian influenza virus (HPAI) virus subtype H5N1 originated from Indonesia to induce apoptosis in Madin-Darby Canine Kidney (MDCK) cells. Three HPAI virus subtype H5N1 isolates with different genetic characteristic namely A/Bird/Bali1/2011, A/Chicken/East Java/BwiI2/2010 and A/Chicken/West Java/1074/2003, were cultured in MDCK cells. Apoptosis was identified by deoxyribonucleic acid (DNA) fragmentation of infected MDCK cells using Apoptotic DNA Ladder Kit. The results showed that all three HPAI virus isolates used in this study did not able to induce apoptosis in the MDCK cells within 5 to 72 hours post infection.
