Abstract

Patients with H5N1 disease have a characteristic complications of pneumonia with acute respiratory syndromedisterss and multi-organ failure associated with cytokine dysregulation, so it is suspected that the clinical forms ofsevere H5N1 disease in humans is caused by dysregulation of cytokine induction of H5N1 virus. Study oncytokines associated with H5N1 influenza virus infection is still limited, while animal studies using virus H5N1/97give conflicting results. Recent studies, showing that in fact the high cytokine is not a common form of the H5N1viruses, so Pathogenecity of H5N1 viruses were not only determined by whether or not the virus can inducehypercytokinemia. In this study we wanted to determine the phenotype of the Indonesia H5N1 virus in inducingcytokine expression. This study compared three Indonesian H5N1 viruses that have different genetic variations ofthe virus including the clade 2.1.1 and two other viruses included in clade 2.1.3 that were infected in Madin DarbyCanine Kidney (MDCK) cell. The MDCK cell that infected virus were observed for 72 hours. We observed theinfection during 72 hours and the cytokines expression were examined using RT-PCR method. The results showedthat the H5N1 influenza viruses used in this study showed the low expression of cytokines IFN-γ, and did notshow any expression of the TNF-α cytokines in MDCK cells infected with the H5N1 virus within 72 hours afterinfection.Keywords : Expression, H5N1 virus, Cytokines, sel Madin Darby Canine Kidney (MDCK)

Abstract

ABSTRACTThis study aims to determine the cross-reaction between the antigen of avian influenza (AI) H5N1 virus clades 2.1.3 and 2.3.2 in duck and chicken sera, which were vaccinated with inactivated AI H5N1 clade 2.1.3 vaccine against AI H5N1 clade 2.3.2 antigen and those vaccinated with inactivated AI H5N1 clade 2.3.2 vaccine against H5N1 clade 2.1.3 antigen. The sera tested were obtained from postvaccination and control (unvaccinated) chickens and ducks in the laboratory condition, and from AI H5N1 postvaccination ducks in the field condition. HI test was conducted by using AI H5N1 clades 2.1.3 and 2.3.2 antigens. The results of HI titer were analyzed by the geometric means and by ANOVA. The results show that cross-reactions in both chicken and duck sera after AI H5N1 clade 2.3.2 vaccination tested with AI H5N1 clade 2.1.3 antigen occurred with low antibody titers, whereas in chicken and duck sera postvaccination with avian influenza H5N1 virus clade 2.1.3 showed cross-reaction with high antibody titer against clade 2.3.2 antigen. The conclusion of this study, postvaccination sera of AI H5N1 clade 2.1.3 provide better cross-reaction compared to the postvaccination sera of AI H5N1 clade 2.3.2.Keywords: sera, chicken, duck, AI H5N1, clade 2.1.3 and clade 2.3.2.

Abstract

ABSTRACTInfectious Bronchitis Virus (IBV) is an acute viral and highly infectious disease which attacks the respiratory system of chicken. The impact of economic losses is very large since it decreases the egg production and itcauses the abnormal of egg shapes, decreased of body weight and death. In Indonesia, the IBV disease is still a serious problem in poultry regarding to many variants which arise from mutations of the IB virus. The decreasing possibility of the vaccination effectiveness due to incompatibility of strains used towards the virus circulated in the field. The variants of IB virus have not been well-documented in Indonesia since the lack of characterization of this virus. In this study, we characterize the IB virus isolates obtained from our local outbreaks in the field in order to determine the variant of IB virus in Indonesia and provide recommendations for the improvements of IB vaccine seed viruses which is adapted to IB virus circulating in the field. The IB virus characterized in this study shows close genetic relationship with the IB virus from Taiwan and China. However, it did not correlate with the local IB virus that has been found previously.Keywords: Identification, Character, IBV, Indonesia

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

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

An indirect enzyme-linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectiousbronchitis (IBV). Antigen was prepared from whole virus of infectious bronchitis local isolate PTS-III serotype.Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera indeveloped ELISA were determined 0.4μg/well, 1:2000 and 1:100, respectively. Correlation optical densities (OD)were compared with a standard commercial ELISA (R2=0.933). The developed ELISA has a better sensitivity to hemagglutinationinhibition (HI) test. The developed local isolate ELISA can be used to detect antibody against infectiousbronchitis virus and it is suitable for sample screening at the diagnostic laboratories.Keywords: ELISA, antibody, chicken, IB PTS-III local isolate

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
