Abstract
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 37samples collected, 20 (54.05%) showed presence of Cryptosporidium sp. infection on faecal smear examination after Ziehl-Neelsen staining. The number of samples positive for Cryptosporidium sp. infection on faecal smear examination was 7 and 13 for Russian Merino and local Changthangi sheep, respectively. The occurrence of Cryptosporidium sp. infection was similar in both sexes, 11/20 (55%) in females and 9/20 (45%) for males. The Age-wise occurrence of Cryptosporidium sp. infection in different age groups was found to be: 50% in less than 2year age group and 50% in more than 2year age group. To the best of our knowledge, this is the first report of Cryptosporidium sp. infection in adult sheep from India. The survival of the parasite at such freezing temperature gives the insight about its cold-resistant nature.
