Prevalence of newcastle disease virus in broiler chickens (Gallus gallus) in Brazil

Some viral diseases in poultry could lead to huge losses to the farmers. Newcastle Disease (ND) and Egg Drop Syndrome (EDS) are a group of infectious viral disease that can cause the decreasein egg production. Newcastle Disease is caused by Avian paramyxovirus type 1 (PMV-1) Paramyxoviridae family. The causative agent of EDS is Duck adenovirus-I Adenoviridae family. Both of these diseases affect the economic losses to the poultry. The main action to prevent hens from ND and EDS virus diseases is vaccination. The success of vaccination can be tested by serology. ND and EDS virus characteristically agglutinate hen's erythrocyte they have Hemagglutine protein on virus envelope so can be tested by hemagglutination. The study was conducted on a commercial poultry farm in order to determine the success of vaccination against ND and EDS. The hens were vaccinated by Newcastle Disease-Infectious Bronchitis-Egg Drop Syndrome (ND-IB-EDS) inactivated vaccines. Serological test was conducted in pre and post vaccination by using microtiter hemagglutination test. The antibody titre is expressed in units of HI log2. The results of the study, the mean antibody titer against ND pre vaccination was 4,53 ± 1,356 HI log2 and antibody titre in 2 nd , 3 rd and 4 th week were 8,67 ± 0,617 HI log2, 7,73 ± 1,335 HI log2 and 5,20 ± 0,862 HI log2 post vaccination. Antibody titre against EDS pre vaccination was 0 ± 0,000 HI log2 and antibody titre post vaccination in 2 nd , 3 rd and 4 th week were 7 ± 1,363 HI log2, 7,27 ± 1,438 HI log2 and 7,6 ± 1,056 HI log2. It showed that ND-IB-EDS inactivated vaccines is serological protective for ND and EDS titres. Keywords: Newcastle Disease, Egg Drop Syndrome, ND-IB-EDS inactivated vaccines, serology. AbstrakBeberapa penyakit virus pada unggas dapat menyebabkan kerugian yang sangat besar pada peternak. Penyakit Newcastle Disease (ND) dan penyakit Egg Drop Syndrome (EDS) adalahkelompok penyakit virus menular yang dapat mengakibatkan penurunan produksi telur. Penyakit ND disebabkan oleh Avian Paramyxovirus tipe 1(APMV-1) familia Paramyxoviridae. Agen penyebab penyakit EDS adalah Duck Adenovirus familia Adenoviridae. Kedua penyakit tersebut berdampak terhadap kerugian ekonomi pada peternakan ayam. Tindakan utama untuk mencegah penyakit ND maupun EDS dengan vaksinasi. Keberhasilan vaksinasi dapat diuji secara serologi. Virus ND dan EDS dapat mengaglutinasi eritrosit ayam karena mempunyai protein hemaglutinin pada amplop virus sehingga dapat dijui dengan uji hemaglutinasi dan hambatan hemaglutinasi. Penelitian dilakukan pada peternakan ayam petelur komersial guna mengetahui keberhasilan vaksinasi terhadap ND dan EDS. Ayam divaksinasi dengan vaksin Newcastle Disease-Infectious Bronchitis-Egg Drop Syndrome (ND-IB-EDS) inaktif. Uji serologi dilakukan pra dan pascavaksinasi menggunakan uji hemaglutinasi teknik mikrotiter.

“…In addition, farms with poor hygiene were more seropositive compared to those with good hygiene. The prevention of IBD disease is based on hygiene and medical prophylaxis, for this purpose it is important to emphasize that no vaccine can solve the problem of IBD if the necessary precautions are not taken, such as the respect for all-in / allout farming methods, cleaning and disinfection of farms and crawl space (Orsi et al, 2010). Birds older than 30 days were less seropositive than younger birds.…”

The present study was conducted to survey about sero-epidemiological status of Newcastle disease (ND), Infectious bronchitis (IB) and Infectious bursal disease (IBD) on Algerian broiler chicken (30 flocks/1200 sera) using ELISA method and to assess the influence of some risk factors related to each disease. Among all investigated flocks, ND was the most seroprevalent disease (63.33%); however, IB and IBD showed less serological positivity (40% and 16.66% respectively). For ND, Cobb 500 Flocks were significantly more seropositive by 78% (p = 0.025) than other strains. Nevertheless, flocks with good hygiene were significantly less seropositive to ND by 26% (p = 0.022). For IB, the risk of seropositivity was significantly lower in spring by 40% (p = 0.036). Although, flocks with higher density or with more than 30 days old were more seropositive respectively by 47% (p = 0.041) and 45% (p = 0.019). At last, when broiler chicken were not boosted by IBD vaccine, flocks appeared to be more seropositive by 48% (p = 0.047); especially in spring by 45% (p = 0.048); or in farms with poor hygiene by 65% (p = 0.004); however, more than flocks 30 days old flocks were less seropositive by 30% (p = 0.009).
