Abstract

The high population of waterfowl subsequently with the high case fatality of poultry and people in West Java regency caused by HPAI H5N1 can raise possibility that waterfowl was a natural reservoir. This research aimed to prove that waterfowl in West Java served as reservoir of AI virus (primarily H5N1) and also identify the virus pathotype based on cleavage site of amino acid sequence. Cloacal swab sample was obtained from healthy and unvaccinated waterfowl from Sukabumi and Bogor Regency. Cloacal swab was propagated in 9 days old embryonic chicken eggs. Allantoic fluid was harvested at the 4th day of incubation and then tested for hemagglutination, and positive isolate continued with virus sub-typing using PCR method. H5 gene from H5N1 isolate then sequenced using dideoxy termination method. Multiple alignment of nucleotide sequences were analysed using MEGA-3.1 program. Sub-typing using PCR method indicated the existence of 25 strain H5N1, 16 strain HxN1, 4 strain H5Nx and 9 virus ND. Characterization of cleavage site amino acid sequence indicated that all H5N1 sample were pathogenic with sequence QRERRRKKR (23 sample) dan QRESRRKKR (2 sample). Waterfowl was HPAI H5N1 virus reservoir. Asymptomatic infection in waterfowl, but the virus shedding gradually occurred and therefore it became potential source of H5N1 virus infection. Our findings suggest that immediate action is needed to prevent the transmission of highly pathogenic avian influenza viruses from the apparently healthy waterfowl into terrestrial poultry or human.

Abstract

Newcastle disease virus (NDV) is very contagious disease agent, and causes many outbreaks trough out thecountry of Indonesia. This study was conducted to determine the virulence of Bali field isolate of NDVbased on haemaglutinin-neuraminidase (HN) protein genes. Four field isolates from different locationswere propagated at fertilized chicken eggs of 9 days old. Allantoic fluid was harvested and NDV wasconfirmed using standard haemaglutination (HA) and haemaglutination inhibition test (HI) methods. Thefragment of HN protein gene was amplified using RT-PCR. The product was sequenced using Big-Dyetermination method. All four isolates grew well with the titer of 2[5]-2[9] HA unit and could be confirmedusing HI test. The HN genes, however, exhibited variations at its 3-D structure and hydrophobicity betweenthe virus that previously circulated in Indonesia and vaccine virus. It is concluded that all four Bali’sisolates under this study are virulent VND of the genotype VII. Further testing is needed to justify the bestformula of NDV vaccine to be used trough out Indonesia.

Abstract

Live Bird Market (LBM) has a high potential for spreading Avian Influenza Virus (AIV) between fowls or from fowl to human. Up to now, a dinamic of avian flue incidents at many LBMs in Bali has not been reported. This research aimed to reveal a dynamic of seroprevalences of avian influenza in ducks at Beringkit (Badung) and Galiran (Kelungkung) LBMs. A total of 35 duck blood samples was collected from each of LBMs. Sampling was conducted monthly from March to August, 2012 . AIV antibody of duck serum was measured using Rapid Hemagglutination Inhibition (Rapid HI) test. Seroprevalence differences were analyzes with Chi-square (?2) Nonparametric statistical test. The results showed that seroprevalences of AIV H5 in ducks at Beringkit and Galiran LBMs were very high, ranged from 68.6% to 100% and 65.7% to 97.1% respectively. A Dynamic of AIV H5 seroprevalences in ducks at Beringkit and Galiran LBM had a similar pattern, except in July 2012. This indicates that VAI H5 has been circulating for a long time and has been to be an endemic virus infection in ducks at LBMs in Bali. It can be suggested that an Avian Influenza Virus monitoring should be done continuously over a long period.

Abstract

Seroprevalence of Newcastle Disease Virus (NDV) infection and the presence of paramyxovirus on ducksat the farmland and the poultry market in Bali have not been known. The purpose of this study was todetermine the comparison of seroprevalence of NDV infection and the presence of paramyxovirus on duckat farmlands and poultry markets in Bali. Locations sampled were Gelgel, Tojan, Akah, Takmung, Tusanvillages in Klungkung Regency, as well as Mengwi, Mengwitani, Lukluk, Sangeh, and Blahkiuh villages ofBadung Regency. The poultry market samples were Galiran of Klungkung Regency, and Bringkit ofBadung Regency. Serum samples and cloacal-tracheal swabs were taken using stratified-random samplingfrom adult ducks of both markets and farmland that had  more than 500 individuals in a flock. Samplingwas carried out every month for 6 months. Antibody against NDV was detected with InhibitionHaemagglutination test (HI). Tracheal and cloacal swabs were propagated in fertile chicken eggs of 9-11days old. Paramyxovirus was detected by the haemagglutination (HA) test and Reverse TranscriptasePolymeraseChain Reaction (RT-PCR). The correlation between NDV seroprevalences at farmland andpoultry markets was analyzed using non-parametric test of Chi-square. The results showed that theseroprevalence of NDV on March until August 2012  reached 45% on farmlands in both regencies, while inthe markets were up to 32.6%. There was no correlation between NDV seroprevalence at farmlands andpoultry markets in the two regencies (r = 0.522, P> 0.05). The paramyxoviruses detected were APMV-5and APMV-8, while NDV was not found.

Abstract

Chicken is important part in Balinese Hindu ceremony. Chicken were used as ceremony are chicken with black feather (siap selem), red feather (siap biing), white feather (siap putih) that a white feather chicken with white colour feet, yellow feather (siap putih siungan), that a white feather chicken with yellow colour feet, and chicken with mixed colour of those four colour (siap brumbun). Limitations of technology owned by community makes the chicken’s breeding doesn’t provide economic added value. The purpose of this service is to provide innovation of artificial insemination technology of chicken production for ceremony. The Innovation is given through counseling and workshops . The results showed that people knowledge about disease and breeding management was increased. The farmer have been able to do artificial insemination and vaccination in chicken. The participant were very enthusiastic in following the activities and understand the disease and how to prevent diseases in chickens. These skills are need to trained constantly to find the comfortable thechnique. The conclusions is farmers have been able to perform artificial insemination in chicken.

Abstract

Background: Single Nucleotide Polymorphisms (SNPs) of the Transcription Factor 7-Like 2 (TCF7L2) diabetes susceptibility gene were located in the noncoding region. Intronic SNP may play a role in mRNA splicing. This study aimed to elucidate whether SNPs of the TCF7L2 gene expressed different mRNA isoforms in the peripheral blood. Methods: Across sectional study was conducted in Legian Bali. A total of 56 subjects were grouped into carrier of TCF7L2SNPs (28 Balinese age 30-74 years,eitherheterozygote or mutant of the rs12255372 SNP [GT or TT], rs7903146 [CT or TT], and rs10885406 [AG or GG])and wild-type of TCF7L2 (28 matched in age and sex Balinese,rs12255372 [GG], rs7903146 [CC], and rs10885406 [AA])which has been identified in the previous study.In this study, the mRNA isolation was done using LS Trizol reagent (Nitrogen®) and variants of the mRNA isoform in the TCF7L2 gene was identified by reverse transcriptase-polymerase chain reaction (RT-PCR) method, using two pairs of overlapping primer.The first primer PCR products were grouped into Group-A, Group-B, Group-C and Group-D. The second primer PCR products were grouped into Group-a, Group-b, Group-c and Group-d. Oral glucose tolerant test (OGTT) was done to both groups.Blood samples were taken during fasting, at 1 hour and 2 hours after the oralglucose load, for blood glucose, and insulin level measurement. Results: There were seven pairs of the group combination including group A-a, A-c, A-d, C-a, C-c, C-dand D-c, and group C-c was the most commonly found among all subjects in this study (42.3%). Subjects with diabetes risk allele were 2.66 times more likely to express group C-ccompared to subjects without diabetes risk allele of SNPs in the TCF7L2 gene (95%CI 1.24–5.72 p=0.011). Mean response of insulin increment after oral glucose load among group C-c was higher compared with the non-group C-c, 84.63±41.01 vs. 62.02±38.09ng/ml (mean difference 22.61 95%CI 0.41–44.80 p=0.046). However, blood glucose level, fasting insulin, HOMA %B and HOMA IR were similar between the two groups. Conclusion: Variants of TCF7L2 gene expressed different mRNA isoformsin the peripheral blood.Compared to subjects without diabetes risk allele of SNPs in the TCF7L2 gene, subject with diabetes risk allele expressed dominant variant isoform mRNA 2.66 timeshigher.The higherresponse of insulin increment after oral glucosewas observedin the dominant variant which may reflectthe early condition of insulin resistant.Keywords: Diabetes, SNP TCF7L2, isoforms mRNA.

Abstract

Penelitian ini bertujuan mengetahui perbedaan respon antibodi yang ditimbulkan oleh vaksin AI dengan seed virus AI H5N1 Indonesia yang dicampur dengan adjuvant berbeda. Formula vaksin yang dicobakan pada penelitian ini adalah monovalen dan polivalen. Tiga isolat virus HPAI subtipe H5N1 yang digunakan adalah Chicken/Denpasar/Unud-01/2004, Chicken/Klungkung/Unud-12/2006, dan Chicken/Jembrana/Unud-17/2006. Adjuvant yang digunakan yaitu Freund's complete dan incomplete adjuvant, aluminium hidroksida, dan immunostimulating complexs (Iscoms). Vaksin monovalen dibuat dengan cara masing-masing isolat virus AI yang telah diinaktivasi dicampur dengan masing-masing adjuvant. Vaksin campuran (polivalen) dibuat dengan mencampur ketiga isolat dengan masing-masing adjuvant. Vaksin disuntikkan secara subkutan pada ayam layer jenis Isa Brown umur 3 minggu dan diulang pada umur ayam 5 minggu  masing-masing sebanyak 0,5 ml/ekor. Pengambilan serum untuk pengujian titer antibodi dilakukan setiap 1 minggu setelah vaksinasi. Pengujian antibodi poliklonal dilakukan dengan uji hambatan hemaglutinasi (HI). Hasil penelitian menunjukkan bahwa ayam percobaan yang divaksinasi dengan adjuvant aluminium hidroksida mempunyai GMT anti-H5 paling tinggi baik pada vaksin monvalen atau polivalen. Adjuvant aluminium hidroksida adalah adjuvant terbaik untuk pembentukan antibodi anti-AI subtipe H5N1 pada ayam.
