Age-related dynamics of protozoan and helminth infections in the red-legged partridge, Alectoris rufa, were studied in an intensive breeding aviary in the Czech Republic before releasing birds for hunting purposes. Pooled fecal samples (n = 900) were examined over 3 rearing seasons (2012–2014). A total of 4 protozoan species, Cryptosporidium baileyi, Cryptosporidium meleagridis, Eimeria kofoidi, and Eimeria legionensis, and 4 helminths, Capillaria phasianina, Eucoleus perforans, Heterakis gallinarum, and Syngamus trachea, was found. The most common parasite was S. trachea (prevalence 20–26%) in dead birds (n = 99), which represents a high risk for breeders. Co-occurrence of protozoans and helminths indicated similarities in infection dynamics throughout the 3 breeding seasons. Mixed infections of Cryptosporidium baileyi and C. meleagridis with other parasitic species are reported for the first time. Our findings provide new insights into breeding of A. rufa and may help to improve the efficacy of disease control strategies and prevention, especially with the potential for spreading of parasitic infections to wildlife through released birds into open areas.

在释放鸟类作狩猎用途之前，在捷克共和国的一个密集繁殖鸟舍中研究了红腿part Alectoris rufa中原生动物和蠕虫感染的年龄相关动态。在三个饲养季节（2012-2014年）中检查了粪便样本（n = 900）。共有4种原生动物，隐孢子虫贝氏，隐孢子虫火鸡，艾美球虫kofoidi，和艾美球虫legionensis，和4个蠕虫，毛细phasianina，Eucoleus穿通，异刺线虫鸡，和Syngamus气管，被发现。最常见的寄生虫是气管链球菌死鸟（n = 99）中的患病率（患病率20–26％），对育种者来说是很高的风险。原生动物和蠕虫的共存表明在三个繁殖季节中感染动力学相似。首次报道了百色隐孢子虫和米氏梭状芽胞杆菌与其他寄生虫的混合感染。我们的研究结果为了解黑曲霉的育种提供了新的见解，并可能有助于提高疾病控制策略和预防的功效，特别是具有通过释放的鸟类将其感染传播到野生生物并传播到开放区域的潜力。
