Year: 2025
Type: article
Abstract: The study was conducted to investigate the circulation of the lumpy skin disease virus and evaluate the protective status after vaccination in 3 districts including Moc Hoa, Duc Hue, and Duc Hoa, Long An province from June 2023 to October 2024. The cattle and lumpy skin disease outbreaks were surveyed in 90 households in 3 districts using the questionnaire. The total of 27 nasal-pooled samples were tested by the real-time PCR to determine the circulation of the lumpy skin disease virus. Serum samples were examined to evaluate the protection of Lumpy skin disease after vaccination using the ELISA method, and the virus neutralization test. The results showed that cattle farming had been increasingly invested in breeds, feed, barns, and farmers’ knowledge. According to the questionnaire results, the rate of Lumpy skin disease was 14.18% with the disease commonly happened in the group of beef under one year old. The monitoring results of the circulation showed that all nasal pooled samples were negative by the real time PCR method. The protection after vaccination reached over 50% (using the ELISA method), while neutralizing antibodies only reached about 40%.
