ABSTRACT: Healthy and/or moribund farmed and wild ballan wrasse Labrus bergylta (>0.5 to 900 g) were sampled from hatcheries (n = 2) and Atlantic salmon Salmo salar cage sites (n = 8) in Scotland between February 2016 and October 2018. Less than half of the sampled individuals (n = 43; 32.3%) had been vaccinated (autogenous polyvalent vaccine; dip and/or injection) against atypical furunculosis (type V and VI), while 20 (15.0%) fish were not vaccinated, and the rest (70 individuals, 52.7%) were of unknown vaccination status. Swab samples from skin lesions, gill, liver, spleen and kidney were inoculated onto a variety of bacteriological agar plates, and bacteriology identification and sequencing analysis was performed on significant bacterial colonies. Atypical Aeromonas salmonicida (aAs) vapA type V was the predominant bacterial species (70/215 bacterial isolates, 32.5% of bacterial samples; 43/117 positive individual fish, 36.8%) isolated in this survey followed by Vibrio species, which were the most geographically prevalent bacteria. Photobacterium indicum/profundum was also isolated from L. bergylta for the first time during this study. The collection of these bacterial isolates provides useful information for disease management. Identifying the aAs isolates involved in disease in ballan wrasse could provide vital information for improving/updating existing autogenous vaccines.

V型非典型沙门氏菌vapA和弧菌spp。是从苏格兰的巴兰濑鱼Labrus bergylta中回收的主要细菌。

摘要：在2016年2月至2018年10月之间，从苏格兰的孵化场（n = 2）和大西洋鲑Salmo salar网箱地点（n = 8）采样了健康和/或濒临灭绝的养殖和野生巴兰濑鱼Labrus bergylta（> 0.5至900 g）。不到一半的样本个体（n = 43； 32.3％）已接种（非自发多价疫苗；浸和/或注射）非典型肺炎（V型和VI型）疫苗，而20种鱼（15.0％）未接种疫苗，其余（70人，占52.7％）的疫苗接种状况未知。将来自皮肤病变，腮，肝脏，脾脏和肾脏的拭子样品接种到各种细菌琼脂平板上，并对重要的细菌菌落进行细菌学鉴定和测序分析。非典型的此次调查中分离出的鲑鱼气单胞菌（a As）vapA型是主要细菌种（70/215细菌分离株，占细菌样品的32.5％；单个鱼的43/117阳性个体鱼，占36.8％），其次是弧菌，其数量最多地理上普遍存在的细菌。在这项研究中，首次也从伯氏乳杆菌中分离出了印度光杆菌/原肠细菌。这些细菌分离株的收集为疾病管理提供了有用的信息。鉴定出与Ballan濑鱼中的疾病有关的As分离株可以为改善/更新现有自体疫苗提供重要信息。
