Video S1. Neurological signs and abnormal swimming behaviour in golden rabbitfish (Siganus guttatus) infected with Streptococcus iniae

This video shows representative neurological signs observed in golden rabbitfish (Siganus guttatus) naturally infected with Streptococcus iniae, including disoriented swimming, loss of equilibrium, and abnormal locomotor behaviour near the water surface. The footage was recorded during disease outbreaks in marine cage culture systems in Vietnam. This video is provided as supplementary material (Video S1) for the article “Streptococcus iniae infection in golden rabbitfish (Siganus guttatus) cultured in marine cages: pathogenicity, virulence profiles and antimicrobial resistance”. The video footage was recorded by Truong Dinh Hoai.

本视频展示了自然感染海豚链球菌（Streptococcus iniae）的金兔子鱼（Siganus guttatus）所表现出的典型神经症状，包括游泳方向紊乱、平衡丧失以及水面附近的异常运动行为。该影像拍摄于越南海水网箱养殖系统的病害暴发期间。本视频作为论文《海水网箱养殖金兔子鱼（Siganus guttatus）海豚链球菌（Streptococcus iniae）感染：致病性、毒力谱与抗菌耐药性》的补充材料（视频S1）提供。本影像由张庭怀（Truong Dinh Hoai）录制。
