Salmonella has long been linked to zoonotic risks, including exotic pets. Parrots are popular pets, and we here describe a salmonellosis outbreak involving Blue-fronted Amazon parrots (Amazona aestiva) confiscated from the illegal pet trade in Brazil. High mortality was observed during the rehabilitation for which the causative agent was identified by cultures, and VITEK®2 GN identification card as Salmonella enterica. Genome sequencing of two isolates revealed serovar Newport ST45. The isolates were resistant to aminoglycosides and fluoroquinolones, and genomic analyses detected characteristic Salmonella Pathogenicity Islands (SPIs) and virulence factors. A phylogenetic analysis with other 275 S. Newport ST45 from different international sources showed clustering with poultry and vegetables isolates and closely related clades of intermingled animal, human, food/environmental isolates from different countries (Tables S1 and S2). The virulent profiles and phylogenetic connection to multiple sources bring the attention to the non-host specificity of these strains highlighting the zoonotic potential in the illegal wildlife trade for companion animals.

巴西鹦鹉新港沙门氏菌爆发：从非法宠物贸易中没收的鸟类可能是人畜共患病的来源

沙门氏菌长期以来一直与人畜共患病风险有关，包括外来宠物。鹦鹉是受欢迎的宠物，我们在这里描述了一场沙门氏菌病爆发，涉及从巴西非法宠物贸易中没收的蓝额亚马逊鹦鹉 ( Amazona aestiva )。在康复期间观察到高死亡率，其病原体通过培养鉴定，VITEK®2 GN 识别卡为肠沙门氏菌。两个分离株的基因组测序显示血清型 Newport ST45。分离株对氨基糖苷类和氟喹诺酮类药物具有抗性，基因组分析检测到特征性沙门氏菌致病岛（SPIs）和毒力因子。与其他 275 S的系统发育分析 . 来自不同国际来源的 Newport ST45 与来自不同国家的家禽和蔬菜分离物以及密切相关的混合动物、人类、食物/环境分离物的进化枝聚集在一起（表 S1 和 S2）。与多种来源的毒性特征和系统发育联系引起了人们对这些菌株的非宿主特异性的关注，突出了非法野生动物贸易中伴侣动物的人畜共患潜力。
