Abstract

Aujeszky 's disease (AD) is a herpesvirus infection causing varying clinical diseases in swine that lead to economic and productivity losses. AD vaccination with marker vaccine has been practised to control AD in swine locally, the latest AD serological status remains unknown. A retrospective analysis was conducted to evaluate the AD seroprevalence among the pig population across 3 regions in Peninsular Malaysia. IDEXX Pseudorabies Virus glycoprotein I (gpI) Antibody Test Kit was used to detect the AD antibodies in the commercial serum samples submitted to Veterinary Laboratory Services Unit (VLSU), Faculty of Veterinary Medicine (FPV), Universiti Putra Malaysia (UPM) during 2019-2020. Descriptive analysis was performed using Microsoft Excel and the results were displayed in tables, pie charts, and bar charts. In 2019,0.60% (5/833) samples from 6.90% (2/29) farms were detected with positive gpI antibodies, while no seropositive samples in 2020. However, there were some samples detected with suspected AD results. The two seropositive farms were located in the central region with samples seroprevalence of 8.70% and 14.29%, respectively within the farm. Among the different age groups, gilts and sows were found positive with seropositivity of 2.56% and 0.83%, respectively. Generally, the results suggest that AD field strains challenges were low or possibly absent in Malaysia from 2019 to 2020; thus, control measures need to be further improved so that AD-free status can be achieved soon.
