Abstract

Penelitian ini bertujuan mengetahui respons antibodi dalam serum ayam petelur terhadap ekskretori/sekretori, dan ditantang dengan telur infektif Ascaridia galli (A. galli) Sebanyak 12 ekor ayam dibagi dalam empat kelompok. Kelompok pertama adalah ayam yang tidak diimunisasi dan tidak diinfeksi (kontrol), kelompok kedua adalah ayam yang diimunisasi dengan dosis 260 µg ekskretori/sekretori larva A. galli, kelompok ketiga adalah ayam yang diinfeksi dengan dosis 1000 telur infektif A. galli, dan kelompok keempat adalah ayam yang diimunisasi dengan dosis 260 µg ekskretori/sekretori dan satu minggu kemudian ditantang dengan dosis 1000 telur infektif A. galli. Respons antibodi pada masing-masing kelompok dianalisis dengan uji enzymelinkedimmunosorbantassay (ELISA) setiap satu minggu selama 10 minggu pascainfeksi. Hasil penelitian menunjukkan bahwa imunisasi dan atau infeksi dapat memicu peningkatan titer antibodi serum secara signifikan (P0,05) selama 10 minggu pascainfeksi. Titer tertinggi adalah 2,63±1,20 OD (optical density) dicapai pada minggu ke-3 pascainfeksi dan titer terendah adalah 1,51±0,48 OD pada minggu ke-0. Ekskretori/sekretori dapat memicu respons antibodi serum ayam petelur terhadap A. galli.

Abstract

Tujuan dari penelitian ini adalah memperoleh informasi infeksi dan sifat-sifat biologis virus Newcastle disease (ND) pada ayam ras maupunayam buras. Sejumlah 529 sampel usap kloaka dikoleksi dari pasar-pasar tradisional dan peternakan rakyat di daerah Bogor dan Tangerang. Sebanyak 20 sampel terdeteksi positif melalui real time reverse transcription-polymerase chain reaction (RRT-PCR) sedangkan dengan isolasi virus terdeteksi positif sebanyak 11 sampel. Selanjutnya empat isolat representasi lokasi dipilih untuk karakterisasi patogenisitas dengan metode mean death time (MDT) pada telur ayam berembrio (TAB) specific pathogen free (SPF), dan karakterisasi antigenisitas menggunakan metode haemagglutination inhibition (HI) dan virus netralisasi (VN) untuk melihat keragaman antar isolat virus. Uji MDT memperlihatkan dua isolat(kode isolat II dan XIII) adalah mesogenik, satu isolat (kode isolate VIII) termasuk lentogenik, dan satu isolat (kode isolat TW) bersifat velogenic. Tiga dari empat isolat menunjukkan hubungan antigenik dengan virus ND strain Komarov dan G7 (genotipe 7) tetapi tidak dengan strain referensi Lasota, sementara isolat velogenic (kode TW) yang berasal dari ayam kampung menunjukkan reaksi silang tinggi dengan antiserum terhadap tiga strain referensi di atas. Sampel-sampel yang diambil di lapang baik itu berasal dari pasar dan peternakan rakyat meskipun secara klinis tidak memperlihatkan gejala sakit dapat diisolasi virus ND dengan karakteristik yang beragam.

Abstract

The Mx gene is an antiviral gene used to determine the resistance or the susceptibility to different types of viruses, including the Avian Influenza (AI) virus subtype H5N1. The AI virus subtype H5N1 infection in chickens causes Mx gene polymorphism. The Mx+ gene shows resistant to the AI virus subtype H5N1, whereas the Mxgene shows signs of susceptible. The objective of this research was to detect the Mx gene in wild aquatic birds using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method with the primer pairs F2 and NE-R2/R and the RsaI restriction enzyme. DNA samples were obtained from eight species of wild waterbirds with positive and negative exposure to the AI virus subtype H5N1. DNA amplification results showed that the Mx gene in wild aquatic birds is found in a 100 bp fragment, which is the same as the Mx gene found in chickens. However, unlike chickens, the Mx gene in wild aquatic birds did not show any polymorphism. This study proves that Mx- based resistance to AI virus subtype H5N1 in different in wild birds than in chickens.

Abstract

Further detailed research is required to obtain deeper information on the role of wild birds on the distribution of Avian influenza in Asia. A research has been carried out on February–June 2007 focused on blood sampling (serosurveillance) of wild birds in Pulau Dua Nature Reserves (CAPD), Serang, Banten. The research is aimed to investigate the infection of AI virus sub-tye H5N1 on the studied wild birds. The blood samples were taken from studied aquatic birds, followed by HI (haemagglutination-inhibition) test. A total of 183 samples represent 7 water bird species were taken i.e Cattle egret Bubulcus ibis, Javan pond-heron Ardeola speciosa, Little egret Egretta garzetta, Intermediate egret Egretta intermedia, Black-crowned night heron Nycticorax nycticorax, Great egret Casmerodius albus and Grey heron Ardea cinerea. The result revealed that 41 (23.27%) samples showed the present of AIV antibodies serotype H5N1 which is identified as positive. Data showed 5 positive-test species, including B. ibis (29.27%), E. garzetta (29.27%), E. intermedia (4.88%), Ardeola speciosa (7.32%), and N. nycticorax (29.27%). A total of 41.46% were infected adult individual, whereas 58.54% were juveniles.

Abstract

Avian Influenza (AI) is one of the strategic animal diseases still considered a priority for control by the Indonesian government. This study aimed to examine the immune response of chickens to various types of H5N1 subtype AI vaccines in Indonesia and to determine the correlation of factors influencing the post-vaccination AI antibody response. Serum samples were tested using the hemagglutination inhibition (HI) test with the standard AI antigen subtype H5N1 strain A/Chicken/Barru/BBVM/41-13/2013 (Clade 2.1.3) and strain A/Chicken/Semarang/04141225-07/2014 (Clade 2.3.2). Antibody titer was calculated using the Geometric Mean Titer (GMT). The correlation analyses were performed to assess the correlation of antibody titer against each of the following factors: age of chicken at the time of sampling, the interval between sampling time and the previous vaccination, and the number of vaccinations performed. The results showed that the average antibody titer value against the AI antigen subtype H5N1 strain A/Chicken/Barru/BBVM/41-13/2013 (Clade 2.1.3) was highest in samples from the South Sumatra Province, namely, Palembang City, which was 26.42 HIU. The results showed a significant correlation (p-value <0,05) between antibody titer and the interval between sampling time and the previous vaccination, the number of vaccination performed and age of chicken at the time of sampling. Therefore, results showed that the immunity developed from vaccination using the AI vaccine seed subtype H5N1 could induce immunity with a protective value of ≥16.

Abstract

Antibody production is becoming a trend, especially during a pandemic like now, although there have been many developments in antibody production in previous research. Antigen synthesis and characterization is one of the determining factors for the success of antibody production. This research developed a method of antigen characterization using the Nuclear Magnetic Resonance (NMR) method. The research conducted in these 4 stages begins with antigen synthesis, then continues with antigen characterization using NMR, then antibody production, and the last stage is antibody characterization using the Enzyme Linked ImmunoAssay (ELISA) method. The results of antigen characterization using NMR show that NAS has been perfectly conjugated with BSA and produces a NAS-BSA conjugate. This is shown by the presence of 1 methylene (CH2) olefinic at δH chemical shift of 6.27 ppm with an integral of 4 and having 1 piece of methine (CH) sp2 at δH chemical shift of 5.73 ppm with an integral of 2. NAS-BSA antigens have been shown to successfully produce antibodies. This is shown from the anti-NAS-BSA, NAS, and Acrylamide antibodies that begin to appear in the second, third and fourth boosting (respectively)

Abstract

Abstract This study aimed to evaluate the acceptance and effectiveness of an Augmented Reality (AR)-based English language learning system, ELSA, among students. Through the analysis of Technology Acceptance Model (TAM) questionnaire data and statistical tests, it was found that students had a positive perception of the usefulness and ease of use of the AR system. The use of ELSA significantly improved students' English language proficiency, particularly in vocabulary and pronunciation. Moreover, ELSA was also able to increase student motivation. However, this study identified disparities in student abilities and a lack of relevance of the material to the local context as challenges. Efforts have been made to address these issues, such as adjusting learning groups and revising materials. Overall, the results of this study demonstrate the great potential of AR in revolutionizing English language learning, especially for young learners, by providing a more interactive, personalized, and effective learning experience.
