During a health survey in the Province of Alessandria (NW Italy) 267 free ranging red-legged partridge (; 137 males and 130 females) were captured in 2009 (n = 101), 2010 (n = 130) and 2011 (n = 36). After biometric data and blood samples collection, animals were released on site. Blood samples were used for the preparation of blood smears. A total of 1.5% of smears presented parasites with a light blue finely granular cytoplasm in red blood cells. The parasites were identified, on the basis of their morphology (no molecular identification was possible), as being sp. juvenile forms. The infestation prevalence was 0.8% in 2010 and 8.3% in 2011. No parasite was observed in 2009. The size of the infested erythrocytes was not altered ( > 0.05) and the nuclear displacement ratio was 0.8 ± 0.2. All the birds were apparently in good health status. To our knowledge this is the first description of sp. in red-legged partridge, and more in general in birds belonging to Galliformes Order in Italy.
在意大利西北部亚历山德里亚省的一次健康调查中，2009年（n = 101）、2010年（n = 130）和2011年（n = 36）共捕获了267只自由放养的红腿鹧鸪（；137只雄性和130只雌性）。采集生物特征数据和血样后，动物被就地放归。血样用于制备血涂片。总共1.5%的涂片显示红细胞内有寄生虫，其细胞质呈浅蓝色、细颗粒状。根据其形态（无法进行分子鉴定），这些寄生虫被鉴定为 sp. 的幼体形式。2010年的感染率为0.8%，2011年为8.3%。2009年未观察到寄生虫。受感染红细胞的大小未改变（>0.05），核移位率为0.8±0.2。所有鸟类的健康状况显然良好。据我们所知，这是红腿鹧鸪中 sp. 的首次描述，更一般地说，是意大利鸡形目鸟类中 sp. 的首次描述。
