Major outbreaks of avian type C botulism have been rarely reported from Central Europe. In this paper, we report the first severe outbreak of avian type C botulism in Poland. In 2011-12, two epizootics caused by Clostridium botulinum took place at Jeziorsko dam reservoir and affected an estimated number of 5500 birds in 2011 and 1600 birds in 2012. In total, 24 species ofwaterbirds were affected, including mainly waterfowl (37.0%), shorebirds (27.0%), rallids (25.7%), and larids (9.1%). Mallards (Anas platyrhynchos) and coots (Fulica atra) were most commonly represented among all affected species (27.5% and 25.0% of all recorded carcasses, respectively). Laboratory analyses confirmed the presence of type C botulinum toxin in the internal organs of paralyzed birds. This case study from the Jeziorsko dam reservoir demonstrates that this type of shallow-water habitat is especially prone to avian botulism outbreaks in the climatic conditions of Central Europe.
中欧地区鲜有禽C型肉毒中毒大规模暴发的报道。在本文中，我们报告了波兰首例严重的禽C型肉毒中毒疫情。2011年至2012年期间，杰济奥尔斯科大坝水库发生了两起因肉毒梭菌引起的动物疫病流行，2011年估计有5500只鸟受影响，2012年有1600只鸟受影响。总共24种水鸟受到影响，主要包括水禽（37.0%）、滨鸟（27.0%）、秧鸡科鸟类（25.7%）和鸥科鸟类（9.1%）。在所有受影响的物种中，绿头鸭（Anas platyrhynchos）和白骨顶鸡（Fulica atra）最为常见（分别占所有记录尸体的27.5%和25.0%）。实验室分析证实，在瘫痪鸟类的内脏中存在C型肉毒毒素。来自杰济奥尔斯科大坝水库的这个案例研究表明，在中欧的气候条件下，这种浅水栖息地特别容易暴发禽肉毒中毒疫情。
