Cover Story: The 22nd Lancefield International Symposium on Streptococci and Streptococcal Diseases (LISSSD 2025) was held on 1–5 June 2025 in Brisbane, Australia. LISSSD 2025 was co-chaired by Assoc Prof Manisha Pandey and Prof Michael Good, and organized by the Lancefield Society, an international association that brings together professionals in the field of streptococci and streptococcal diseases to raise awareness, promote scientific collaboration and research, and improve diagnosis, prevention, and treatment. The meeting offered a cutting-edge scientific program covering the latest advances in clinical aspects, pathogenesis, novel diagnostics, therapeutics, and vaccine developments related to acute streptococcal infections as well as post-streptococcal sequelae.
