A cross-sectional study was carried out to determine the prevalence of pathogenic zoonotic agents (flaviviruses, avian influenza viruses (AIVs), Salmonella spp. and Toxoplasma gondii) in feral pigeons and sympatric zoo animals from Córdoba (Southern Spain) between 2013 and 2014. Antibodies against flaviviruses were detected in 7.8% out of 142 (CI95%: 3.7-11.8) pigeons, and 8.2% of 49 (CI95%: 0.9-15.4) of zoo animals tested. Antibodies with specificity against West Nile virus (WNV) and Usutu virus (USUV) were confirmed both in pigeons and in zoo birds. Even though seropositivity to AIVs was not detected in any of the analyzed pigeons, 17.9% of 28 (CI95%: 3.7-32.0) zoo birds tested showed positive results. Salmonella spp. was not isolated in any of 152 fecal samples collected from pigeons, while 6.8% of 44 zoo animals were positive. Antibodies against T. gondii were found in 9.2% of 142 (CI95%: 4.8-13.6) feral pigeons and 26.9% of 108 (CI95%: 19.6-34.1) zoo animals. This is the first study on flaviviruses and T. gondii in feral pigeons and captive zoo species in Spain. Antibodies against WNV and USUV detected in non-migratory pigeons and captive zoo animals indicate local circulation of these emerging pathogens in the study area. T. gondii was widespread in species analyzed. This finding could be of importance for Public Health and Conservation of endangered species present in zoo parks. Pigeons and zoo animals may be included as sentinel species for monitoring zoonotic pathogens in urban areas.
2013年至2014年期间，开展了一项横断面研究，以确定西班牙南部科尔多瓦的野生家鸽和同域分布的动物园动物中致病性人畜共患病原体（黄病毒、禽流感病毒、沙门氏菌属和刚地弓形虫）的流行情况。在142只家鸽中有7.8%（95%置信区间：3.7%-11.8%）检测到抗黄病毒抗体，在49只接受检测的动物园动物中有8.2%（95%置信区间：0.9%-15.4%）检测到抗黄病毒抗体。在家鸽和动物园鸟类中均确认存在针对西尼罗河病毒（WNV）和乌苏图病毒（USUV）的特异性抗体。尽管在所分析的家鸽中未检测到禽流感病毒血清阳性，但在28只接受检测的动物园鸟类中有17.9%（95%置信区间：3.7%-32.0%）呈阳性结果。从152份家鸽粪便样本中均未分离出沙门氏菌属，而在44只动物园动物中有6.8%呈阳性。在142只野生家鸽中有9.2%（95%置信区间：4.8%-13.6%）以及在108只动物园动物中有26.9%（95%置信区间：19.6%-34.1%）检测到抗刚地弓形虫抗体。这是西班牙首次对野生家鸽和圈养动物园物种中的黄病毒和刚地弓形虫进行研究。在非迁徙家鸽和圈养动物园动物中检测到的针对西尼罗河病毒和乌苏图病毒的抗体表明这些新出现的病原体在研究区域内存在本地传播。刚地弓形虫在所分析的物种中广泛存在。这一发现可能对公共卫生和动物园中濒危物种的保护具有重要意义。家鸽和动物园动物可作为监测城市地区人畜共患病原体的哨兵物种。
