The objective of this study was to obtain primary information on the occurrence of blood parasites and intensity of infection in the Dunnock Prunella modularis in the montane region of Slovakia. Altogether 109 birds were examined during the years 2006-2010. The occurrence of Haemoproteus sp., Leucocytozoon fringillinarum and Trypanosoma sp. was documented. Blood parasite prevalences of 45% by microscopic examination and 55% by PCR diagnostics were found. The prevalence of Leucocytozoon sp. was found to be dependent on host sex with males showing a significantly higher intensity of infection with Leucocytozoon. Adult birds showed significantly higher infection prevalence than subadults. The prevalences of both Leucocytozoon sp. and Haemoproteus sp. were significantly dependent on bird age. The intensity of infection with Haemoproteus and Leucocytozoon was positively correlated and higher intensity of infection was confirmed in adult birds then in subadults birds. The prevalence of blood parasites in our samples was significantly higher in comparison to most other studies from different countries of Europe conducted at lower altitudes, indicating that the montane zone is especially favourable for the transmission of Leucocytozoon and Haemoproteus species.
本研究的目的是获取斯洛伐克山区褐岩鹨血液寄生虫的发生情况及感染强度的基础信息。2006年至2010年期间共检查了109只鸟。记录到血变原虫属、燕白细胞虫和锥虫属的存在。通过显微镜检查发现血液寄生虫患病率为45%，通过聚合酶链反应诊断为55%。发现白细胞虫属的患病率取决于宿主性别，雄性感染白细胞虫的强度明显更高。成年鸟的感染患病率明显高于亚成鸟。白细胞虫属和血变原虫属的患病率都明显取决于鸟的年龄。血变原虫和白细胞虫的感染强度呈正相关，成年鸟的感染强度高于亚成鸟。与欧洲其他不同国家在较低海拔地区进行的大多数其他研究相比，我们样本中血液寄生虫的患病率明显更高，这表明山区对白细胞虫属和血变原虫属的传播特别有利。
