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

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan yang ditambahkan laktoferin sapi terhadap berat badan dan leukosit anak babi Landrace. Penelitian dilakukan pada peternakan komersial di Desa Yeh Gangga, Kecamatan Sudimara, Kabupaten Tabanan. Sebanyak 12 anak babi Landrace dari tiga induk yang berbeda digunakan sebagai sampel, dengan pembagian dua kelompok, yaitu kelompok kontrol dan perlakuan. Kelompok kontrol tidak diberikan perlakuan. Kelompok perlakuan diberikan laktoferin sapi selama 7 hari dengan pemberian satu kali dalam satu hari. Penimbangan berat badan anak babi Landrace dilakukan setiap lima hari, kemudian data dianalisis dengan Student’s T-test. Hasil analisis data periode penimbagan berat badan anak babi umur 10 – 35 hari berpengaruh nyata (P<0,05). Pengabilan darah dilakukan pada post perlakuan kemudian diuji dengan uji hematologi. Data yang diperoleh dianalisis menggunakan Student’s T-test. Hasil penelitian menunjukkan bahwa rerata diferensial leukosit tidak berbeda nyata (P>0,05) antara kelompok kontrol dan kelompok perlakuan. Masing-masing komponen leukosit pada kelompok kontrol maupun kelompok perlakuan berada pada rentang nilai normal. Rerata total leukosit anak babi pasca pemberian laktoferin tidak berbeda nyata (P>0,05) antara kelompok kontrol dan kelompok perlakuan.

Abstract

Penelitian ini bertujuan untuk mengetahui persentase anjing lepasan yang memiliki antibodi protektif terhadap virus rabies berdasarkan topografi wilayah tempat tinggal anjing di Kabupaten Badung. Lokasi pengambilan sampel, yaitu di Kecamatan Mengwi (Desa Mengwi, Mengwitani, Sempidi) yang mewakili wilayah perkotaan, Kecamatan Petang (Desa Pangsan, Petang, Belok) yang mewakili wilayah pegunungan dan Kecamatan Kuta Selatan (Desa Jimbaran, Ungasan, Tanjung Benoa) yang mewakili wilayah pantai. Objek penelitian adalah 90 ekor anjing lepasan dengan umur di atas tiga bulan. Sampel serum diuji menggunakan kit enzyme linked immunosorbent assay (ELISA). Rata-rata titer antibodi anjing lepasan terhadap virus rabies di Kabupaten Badung adalah 0,24±0,31 IU/mL. Persentase anjing lepasan yang memiliki antibodi terhadap virus rabies (e” 0,1 IU/mL) adalah 100%. Sementara itu, persentase anjing lepasan yang mempunyai antibodi protektif terhadap virus rabies (e” 0,5 IU/mL) adalah 11,1%. Persentase anjing yang memiliki antibodi dan yang memiliki antibodi protektif terhadap virus rabies di masing-masing wilayah topografi tidak berbeda nyata. Penelitian ini memberikan fakta bahwa semua anjing lepasan yang dijadikan sampel di tiga wilayah topografi Kabupaten Badung memiliki antibodi rabies, dan hanya 11,1% anjing lepasan yang memiliki antibodi protektif terhadap virus rabies. Perlu strategi dari pemerintah untuk memfokuskan sasaran vaksinasi pada anjing lepasan, mengingat wilayah jelajah anjing lepasan lebih luas sehingga penularan rabies oleh anjing lepasan kemungkinan akan sangat besar. Hal ini perlu dilakukan untuk mencapai keberhasilan dalam pemberantasan rabies di Kabupaten Badung.
