Ladakh is the high altitude (11,184 ft above sea level) cold desert region in the state of Jammu & Kashmir (India), where winter temperature goes below - 35 °C. A total of 37 faecal samples were collected from local Changthangi and Russian merino sheep of the Leh region of Ladakh, having the history of diarrhoea and emaciation, followed by death. Of the 37 samples collected, 20 (54.05%) showed presence of Cryptosporidium sp. infection on faecal smear examination after Ziehl-Neelsen staining. The number of samples positive for sp. infection on faecal smear examination was 7 and 13 for Russian Merino and local Changthangi sheep, respectively. The occurrence of sp. infection was similar in both sexes, 11/20 (55%) in females and 9/20 (45%) for males. The Age-wise occurrence of sp. infection in different age groups was found to be: 50% in less than 2 year age group and 50% in more than 2 year age group. To the best of our knowledge, this is the first report of sp. infection in adult sheep from India. The survival of the parasite at such freezing temperature gives the insight about its cold-resistant nature.
拉达克是印度查谟和克什米尔邦的高海拔（海拔11,184英尺）寒冷沙漠地区，冬季气温会降至零下35摄氏度以下。从拉达克列城地区当地的羌塘羊和俄罗斯美利奴羊中总共采集了37份粪便样本，这些羊都有腹泻、消瘦并最终死亡的病史。在采集的37份样本中，20份（54.05%）经齐-尼氏染色后粪便涂片检查显示存在隐孢子虫属感染。粪便涂片检查中，俄罗斯美利奴羊和当地羌塘羊隐孢子虫属感染阳性样本数分别为7份和13份。隐孢子虫属感染在两性中的发生率相似，雌性为11/20（55%），雄性为9/20（45%）。不同年龄组隐孢子虫属感染的年龄分布情况为：2岁以下年龄组为50%，2岁以上年龄组为50%。据我们所知，这是印度成年绵羊隐孢子虫属感染的首次报告。该寄生虫在如此低温下存活，揭示了其耐寒特性。
