Abstract

The aim of the study was to know avian influenza (AI) infection in field by using serology test in threemarketing area of AI vaccines. Haemagglutination inhibition methode was used in this test. There werefour antigen strains of AI subtype H5N1 clade 2.1.3 (AIstrainA/Chicken/West Java/PWT-WIJ/2006, AIstrain A/Chicken/Garut/BBVW-223/2007, AI strain A/Chicken/West Java-Nagrak/30/2007, and AI strainA/Chicken/Pekalongan/BBVW-208/2007) and 2 antigen strains of AI subtype H5N1 clade 2.3.2 (AI strainA/duck/Sukoharjo/BBVW-1428-9/2012 and AI strain A/duck/Sleman/BBVW-1463-10/2012) was used inthis study for HI test. The result presents that 93,33% chicken farms in three marketing area of PT. SanbioLaboratories have positive antibody titre to AI subtype H5N1 clade 2.1.3. This titre may be obtained fromAI clade 2.1.3 vaccination. From 15 samples, 92,86% are positive to AI subtype H5N1 clade 2.3.2A/duck/Sukoharjo/BBVW-1428-9/2012 and 92,31% are positive to A/duck/Sleman/BBVW-1463-10/2012 evenwithout AI clade 2.3.2 vaccination. This antibody titre may be obtained from AI clade 2.1.3 vaccine crossprotection or field infection.

Abstract

The aim of this study was to investigate antibody response of specific pathogen-free (SPF) chickens vaccinatedwith single inactivated Newcastle disease (ND) vaccine and combined inactive ND and avian influenza(AI) vaccines and to known the efficacy of both vaccines. The vaccines used were killed ND vaccine andkilled ND-AI vaccine produced by PT. Sanbio Laboratories Bogor, West Java. SPF chickens were vaccinatedwith 3 different doses. Antibody titer of SPF chickens against ND virus were determined byhaemagglutination inhibition (HI) test. As many as 130 two week old SPF chickens were used and theywere divided into 2 groups (A and B) consisting of 60 chickens and 10 chickens were used as control withoutvaccine. Group A chickens were vaccinated with ND-K vaccine and group B were vaccinated with combinedkilled ND-AI vaccines. Each group was further divided into 3 subsgroups (1, 2 and 3) consisting 20 chickens.Subgroups 1, 2 and 3 were vaccinated intramuscularly respectively with intramuskular 1, 1/10 and 1/100doses of each vaccines. Antibody response of chickens against ND virus was examined before vaccinationand every three week after vaccination and was expresses as geometric mean titre (GMT) HI units. Theresult showed that the titre antibody against ND increased at the second week following the vaccination.The antibody titer against ND virus of chickens vaccinated single killed ND at the second week in eachdose were 6.05 GMT HI unit, 4.05 GMT HI unit, and 0.9 GMT HI unit. The antibody titre at the third week were 7.90 GMT HI unit ,5.40 GMT HI unit and 2.20 GMT HI unit. The antibody titre against ND virus ofchickens vaccinated with combined ND-AI vaccine at the second week were 6.30 GMT HI unit , 4.15 GMTHI unit , and 2.05 GMT HI unit. At the third week, the antibody titre against ND virus of chickensvaccinated with combined ND-AI vaccine in each subgroup were 7.45 GMT HI unit, 5.60 GMT HI unit , and2.40 GMT HI unit . It showed that the antibody titers at single doses of killed ND vaccine (7.90 GMT HIunit) and combined ND-AI vaccine (7.45 GMT HI unit) at the third week after vaccination were both stilleffective as both titres were above standard protective titre.
