Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test

Judul: Studi Kemampuan Vaksin ND-IB Lived: Pembentuk Kekebalan dan Perlindungan terhadap Paparan Virus Newcastle Disease pada Ayam Pedaging
Abstrak: The objective of this study was to measure the antibody titer of broilers were vaccinated with lived ND LaSota-IB H120 vaccine, and to observe the clinical signs and pathological lesions on challenged group. As much as 60 commercial Day Old Chicks were used in the experimental. Twenty chickens were bleed at day one to measure maternal antibody against Newcastle Disease (ND) using Hemaglutination Inhibition (HI) Test. The remaining fourty chickens were divided into four groups. Each group consisted of ten broilers. Group K1 and K2 were unvaccinated. Group K3 and K4 were vaccinated on the 2nd day according to the manufacture procedure. Challenge was carried out on 14th day (12th day post vaccination) to group K1 and K3 with ND Indonesia isolate virus. Blood samples from unvaccinated and vaccinated group were taken on 7th, 14th, and 22nd day. The result showed that chickens had high maternal antibody titer. The combination of intranasal and oral vaccination was able to produced protective antibody against ND viral infection. Vaccination was able to reduced lethargy and petechiae cecal tonsil. The clinical signs and pathological lesions were more severe on unvaccinated group.
