Analysis of Quality Surveillance Results for Veterinary Chemical Drugs
Chen Yu Lin
Abstract
The management process of veterinary drugs in Taiwan includes licensing applications, ingredient evaluations, marketing authorizations, as well as subsequent quality monitoring and usage management, thereby establishing a comprehensive life-cycle management framework for veterinary drugs. Among these, post-market quality monitoring is a key regulatory measure for safeguarding drug safety. Over the years, the Animal Drugs Inspection Branch has cooperated with the competent authority to conduct quality inspections of marketed veterinary chemical drugs, in order to ensure effective oversight of marketed drug quality. Analysis of sampling inspection results over the past decade indicates that the majority of samples were products manufactured by domestic producers, accounting for approximately 73% of the samples. Injectable preparations were the most common dosage form, comprising about 37% of the samples. The most frequently inspected active ingredient was amoxicillin, followed by lincomycin. Overall quality inspection results were stable across years, with an average pass rate of 96%. Non-compliant products were predominantly penicillin G–containing sterile injectable suspensions, indicating that further strengthening of quality control measures is necessary for this category of products.
The examination of atypical porcine pestivirus in pigs
Kuo-Jung Tsai
Abstract
Atypical porcine pestivirus (APPV) was first identified in 2015 during procine diseases surveillance in the United States, with a genome sequence clearly distinct from typical pestiviruses, including classical swine fever virus, bovine viral diarrhea virus, and border disease virus. Following studies have suggested an association between APPV infection and congenital tremors in piglets, as demonstrated through experimental inoculation of pregnant sows. In recent years, APPV has been reported in commercial swine herds in multiple countries, including the United States, Europe, and Asia; but available data from Taiwan remains limited. In this study, samples from culled pigs were tested for APPV using real-time reverse transcription PCR (RRT-PCR), and the presence of APPV nucleic acids was further confirmed by nucleotide sequencing, providing evidence of APPV presence in Taiwan.
Exploring the serological technique of bat lyssavirus in the UK
Shu-Chia HU
Abstract
From November 22 to December 6, 2025, a researcher from the Veterinary Research Institute (VRI), Taiwan visited the Animal and Plant Agency (APHA), UK and was trained for the serological technique of bat lyssavirus . The training covered the Fluorescent Antibody Virus Neutralization (FAVN) test and a modified FAVN (mFAVN) assay. Three batches of samples were tested by mFAVN. The mFAVN was performed using Taiwan bat lyssavirus 2 provided by the VRI to the APHA, as well as canine and feline serum samples collected by the APHA. During the training period, in-depth exchanges were conducted between researchers regarding bat lyssavirus surveillance strategies and recent research findings, through which participant gained substantial benefits in both professional knowledge and practical experiences. The training also provided an opportunity for both laboratories to discuss potential directions for future collaborative research, with the aim of establishing a long-term and stable partnership. Such collaboration is expected to further strengthen the research capacity of the rabies laboratory of the VRI.
Report of the 11th Asian Pig Veterinary Society Congress
Yu-Liang Huang
Abstract
The 11th Asian Pig Veterinary Society Congress in 2025 was organized by the Asian Pig Veterinary Society, with the aim of promoting collaboration and exchange in swine disease control, pig production technologies, and animal welfare across Asia. The main theme of this congress was “Sustainable Future of Asian Pig Production.” Swine diseases remained a major focus of the meeting, with particular emphasis on the latest international research advances and disease control strategies related to porcine reproductive and respiratory syndrome (PRRS), African swine fever (ASF), classical swine fever (CSF), and porcine epidemic diarrhea (PED). ASF continues to spread in East and Southeast Asia, with the emergence of genotype I/II recombinant strains and increasing reports of chronic ASF cases. In Asia, CSF outbreaks are still reported in Japan, especially among CSFV infection of wild boar, where effective control remains challenging. PRRS and PED persist as endemic diseases in many Asian countries, continuously impacting pig production performance and growing rates. Through this congress, the Veterinary Research Institute (VRI) of Taiwan shared research achievements and experiences in swine disease control with other Asian countries and engaged in scientific exchange with international swine health experts. These interactions contributed to strengthening VRI capacity in the diagnosis, research, and development of prevention and control strategies for transboundary animal diseases.
