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. Key Words: HPAI, H5N1, Reservoir, Water Fowl

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

Colibacillosis by Avian Pathogenic Escherchia coli (APEC) is an infectious disease in poultry. The ability of APEC to cause disease depends on various virulence factors, including hlyF. The study aimed to prove the existence of the APEC hlyF gene in Bali and to find out the DNA sequences of these hlyF genes and their kinship with the hlyF gene from other countries. This study used two APEC isolates from free range chicken in Tabanan and Badung regencies. The isolates have been purified and were available at the Bacteriology Laboratory of Veterinary Medicine Faculty, Udayana University. DNA isolates were isolated using Chelex 10%. The hlyF gene is amplified using published DNA primers by polymerase chain reaction (PCR). PCR products were sequenced at First Base Laboratories in Malaysia using the Sanger’s Dideoxy Nucleotide Termination method. Both the hlyF gene sequences that can be analyzed have 100% homology with a readable length of 518 bp. Phylogenic test with 25 DNA sequences of hlyF gene on Escherichia coli and other bacteria in the world using UPGMA method with bootstrap (500 repetitions) was conducted with MEGA 5.2. All data have six polymorphic sites of nucleic acid and two polymorphic sites of amino acid . The hlyF gene from Bali was in same group with hlyF genes from various countries in the world. This gene can be used as a pathogenic marker of APEC in Indonesia.

Abstract

Penelitian ini bertujuan untuk mengetahui perhatian pemilik anjing dalam mendukung  Bali bebas Rabies. Penelitian dilakukan pada bulan Desember 2010, di Desa Kukuh Tabanan, Desa Jagapati Badung, dan Desa Seraya Karangasem dengan jumlah responden sebanyak 500 orang. Cara pengumpulan data yang digunakan dalam penelitian ini adalah wawancara dengan panduan daftar pertanyaan yang ada pada kuisioner. Hasil penelitian menunjukkan bahwa Jumlah kepemilikan anjing dari satu ekor sampai 4 ekor. Masyarakat memelihara anjing sebagian besar dengan tujuan untuk menjaga rumah (77,6%). Perhatian masyarakat pemilik anjing terhadap kesehatan dan perawatan kesehatan anjingnya, dilihat dari memandikan anjing, jumlah pemberian pakan, dan memeriksakan anjingnya ke dokter hewan masih rendah. Anggota keluarga yang sering  berinteraksi (memberikan pakan, memandikan) dengan anjing adalah ayah. Responden yang menjawab anjing bisa  dipegang pemilik sebanyak 93,6%. Berdasarkan atas jenis kelamin, masyarakat sebagian besar memelihara anjing jantan (84,8%). Anjing yang dipelihara dengan cara dilepas (64%). Kesimpulan dari penelitian ini adalah perhatian masyarakat dalam memelihara anjing dalam upaya mendukung Bali bebas rabies masih rendah. Disarankan perlu dilakukan kegiatan sosialisasi dan  edukasi tentang pemeliharaan anjing pada masyarakat.
