Vietnam is renovating its animal disease diagnosis, surveillance and control systems with the aim of increasing the productivity of livestock. Current technology for disease detection is based on Enzyme-Linked Immunosorbent Assay (ELISA). However, commercial kits/reagents and equipment are usually expensive and not suitable for routine use in developing countries. An affordable alternative is latex agglutination technology which is robust and requires minimal equipment and training to operate. This small project aims to explore the feasibility of developing latex agglutination antibody detection systems for Classical Swine Fever virus, avian infectious bursal disease, porcine parvovirus and bovine herpesvirus-1.
