Abstract

Red sea bream iridoviral disease (RSIVD) is caused by red sea bream iridovirus (RSIV), adouble stranded DNA of Icosahedral virus with a diameter of 120-240 nm [1]. RSIV is  one  of the  species  of  the Megalocytivirus,  Genus  of  the  Iridoviridae Family,  first reported to infect red sea bream (Pagrus major) fish, at Sikoku Island, Japan 1991, and since then it has been noted to cause considerable economic losses to fisheries in Singapore, Taiwan, Thailand, Korea, Philippines, Malaysia and also in Indonesia [2,3,4]. Rapid transmission with high mortality rates in fish populations infected becomes a serious threat to the aquaculture fishery business. Stained imprints or tissue sections [1], monoclonal antibody technique (MAb), Immunofluorescent Antibody Tests (IFAT) [5], Polymerase Chain Reaction (PCR) [6] Electron Microscope and Multiplex PCR [2] methods have been introduced.  Although it is very effective for detecting RSIVD in infected fish, but requires training and specialized equipment at a high cost.Co-agglutination test is a diagnostic method, used both in humans and animals in detecting bacterial or viral diseases [7], this method is fast, easy to use, and does not require special equipment. Test results from co-agglutination are easily seen macroscopically, so it is suitable if developed in RSIVD detection in the field case. This study aims to create and conduct RSIVD co-agglutination kit field tests supported by molecular studies and diagnostic analysis of the sensitivity and specificity of the accuracy and reliability of the kit. Then the test results will be compared from the pooling and individual samples.

Abstract

For the past few years, Edwardsiella tarda has become major problem in African catfish culture in Jambi. Detection by biochemical characteristic can lead to inaccurate result and there is a necessity to develop more specific and accurate method, one of which is Agar Gel Precipitation (AGP) method. Six samples each were collected from two African catfish farm located in District Sungai Gelam and Telanai Pura in Jambi, which was showed clinical signs of E. tarda outbreak with more than fifty percent mortality rate. Heat stable soluble antigen was prepared from 2 groups of pure culture isolated from sample for AGP test. Antiserum for test wells was antiserum of E. tarda (ATCC 15947) that have been produced by inoculating whole-cell antigen (heat-stable) and flagellar antigen (formalin-killed) in rabbit. For control positive, soluble antigen prepared from E. tarda (ATCC 15947), and control negative from Aeromonas hydophila (ATCC 35654) and Edwardsiella ictaluri (NCIMB 13272). Both antiserums were able to show positive reaction visible by the formation of specific precipitin lines between antiserum and antigen wells, and there was no precipitin reaction for negative control. In conclusion AGP method is a one of reliable technique to identify E. tarda.

Abstract

Egg drop syndrome (EDS) is a disease that attacks layer hens in the production phase causing failure of peak eggs production, decreased in eggs production, and presence of eggs without shell. This study was conducted to isolate and identify the EDS virus in the chicken layer that was diagnosed as a disease of EDS by hemagglutination (HA) and  hemagglutination inhibition (HI) assays. Specific pathogen free (SPF) layerchickens which were passing through the production phase fed with food which was mixed with egg without shell from SR/WNO/2011. The chicken together with chicken FF/Sleman/2011 were dissected when pathological lesions, such as the dents or palor eggs observed. The uterine tissues were then collected for samples. Infundibulum of chicken FF/Sleman/2011 was explored and was found out that the eggs were lack ofegg shells. The eggs were then washed using sterile PBS. The three subsequent samples were propagated in the allantoic fluid of embryonated duck eggs for 16 days. Allantoic fluid was harvested after being incubated for 4 days. It was then tested by HA and HI assay by use of avian influenza virus (AIV), Newcastle disease virus (NDV), and EDS anti serum. The HA and HI test with EDS anti serum used chickens erythrocytes in percentageof 0,8. The HA test in uterine sample of both SR/WNO/2011 and FF/Sleman/2011 showed the titer 23 HA units and egg washed water sample of FF/Sleman/2011 showed titer 22 HA units. The HI test for comparison with ND and AI anti serum was negative, while the test with EDS anti serum showed positive results. Based on the HA and HI test results, it was concluded that the virus grown in the allantoic fluid is EDS virus.

Abstract

Infectious Bursal Disease (IBD) adalah penyakit virus yang bersifat akut dan infeksius serta menyerang pada unggas muda yang berumur kurang dari 4 bulan. Sejauh ini data molekuler virus IBD isolat Indonesia sangat minim, oleh karena itu penelitian ini bertujuan untuk mengidentifikasi dan mengarakterisasi gen VP-2 virus IBD yang telah ada di Indonesia. Sampel penelitian diperoleh dari kasus terdiagnosa IBD yang terjadi di peternakan ayam komersial broiler dan layer. Sampel Bursa dipersiapkan untuk dilakukan isolasi menggunakan telur ayam berembrio SPF. Membran korioalantois dipanen dan dilakukan identifikasi dengan metode RT-PCR dengan gen target VP-2. Hasil amplifikasi selanjutnya dilakukan pengurutan DNA. Data nukleotida hasil pengurutan DNA dianalisis dengan program MEGA 6, meliputi pesejajaran, prediksi asam amino, dan konstruksi pohon kekerabatan antara virus yang diteliti dengan beberapa virus yang telah dipublikasi di bank gen terutama virus IBD yang bersirkulasi di Indonesia. Hasil penelitian ini diperoleh data bahwa ayam yang terdiagnosis penyakit IBD dapat ditentukan penyebabnya sebagai virus IBD. Hasil analisis urutan penanda patogenisitas molekuler menunjukkan virus yang virulen. Analisis pohon kekerabatan 2 isolat IBD SR/Lay-WNO-DIY dan IBD Potrow/Lay-SLM-DIY termasuk dalam kelompok virus IBD tipe klasik, sedangkan lima virus lainnya, yaitu IBD Yanti/Lay-SLM-DIY; IBD Lampung/Bro/IL; IBD Fung/Lay-SLM-DIY-BF1, IBD Fung/Lay-SLM-DIY-BF2, dan IBD Fung/Lay-SLM-DIY-BF3 termasuk dalam kelompok vvIBD strain Indonesia.
