从挪威采集了 1190 只野生鹿科动物的粪便样本，并分析了原生动物寄生虫贾第鞭毛虫和隐孢子虫的包囊/卵囊。样本取自狩猎季节期间拍摄的驼鹿 (Alces alces)、马鹿 (Cervus elaphus)、狍 (Capreolus capreolus) 和驯鹿 (Rangifer tarandus) 的幼崽、一岁幼体和成年体。在 455 只驼鹿中发现了 15 只（3.3%）隐孢子虫，在 289 只马鹿中发现了 1 只（0.3%）隐孢子虫，在 291 只狍鹿中发现了 18 只（6.2%）隐孢子虫，但在 155 只驯鹿中没有发现隐孢子虫。在 56 头驼鹿（12.3%）、5 头马鹿（1.7%）、45 头狍子（15.5%）和 11 头驯鹿（7.1%）中发现贾第鞭毛虫。小牛的感染率最高，但这仅对驼鹿中的贾第虫以及狍中的隐孢子虫和贾第虫具有统计学意义。犊牛通常感染强度最高，但这种差异仅对于感染贾第虫且感染强度最高的犊牛才具有统计学意义。在多个地理区域的样本中都发现了贾第鞭毛虫和隐孢子虫，这表明这些寄生虫分布在挪威各地的鹿科种群中，尤其是驼鹿和狍子中。这是首次发表关于驼鹿隐孢子虫和驯鹿贾第鞭毛虫的报告。 (c) 2006 Elsevier B.V 保留所有权利。
Faecal samples were collected from 1190 wild cervids in Norway and analyzed for cysts/oocysts of the protozoan parasites Giardia and Cryptosporidium. Samples were from calves, yearlings and adults of moose (Alces alces), red deer (Cervus elaphus), roe deer (Capreolus capreolus) and reindeer (Rangifer tarandus) shot during the hunting season. Cryptosporidium was found in 15 (3.3%) of 455 moose, 1 (0.3%) of 289 red deer, 18 (6.2%) of 291 roe deer, but was not found in any of 155 reindeer. Giardia was found in 56 (12.3%) moose, 5 (1.7%) red deer, 45 (15.5%) roe deer and 11 (7.1%) reindeer. The calves had the highest prevalence of infection, but this was only statistically significant for Giardia in moose and for Cryptosporidium and Giardia in roe deer. Calves generally had the highest intensity of infection, but this difference was only statistically significant for calves with Giarda and the highest intensity of infection. Both Giardia and Cryptosporidium were found in samples from several geographical areas, indicating that these parasites are distributed among the cervid population in all parts of Norway, especially in moose and roe deer. This is the first published report of Cryptosporidium in moose and of Giardia in reindeer. (c) 2006 Elsevier B.V All rights reserved.
