Prevalence and analysis of associated risk factors for Cryptosporidium infection in lambs in Jammu district

摘要

An epidemiologic study was carried out to investigate the prevalence and analysis of risk of Cryptosporidium infection in lambs in Jammu district. Faecal samples of 120 lambs of different age groups viz., <1 month, 1–3 months and 3–6 months were assessed. Cryptosporidium oocysts were identified by using modified Zeihl Neelsen technique. Statistical analysis showed that infection rates were significantly higher in lambs of <1 month age group (65 %) than other two age groups (p < 0.05). Similarly, cryptosporidial infection rates were significantly higher in diarrhoeic (54.41 %) than in non diarrhoeic lambs (34.61 %). Winter records highest prevalence (73.33 %) which varied significantly. Sex wise higher prevalence was observed in females (51.56 %) as compared to males (39.28 %). The relationship between intensity of infection and various epidemiological factors showed that highest intensity was observed in lambs of 0–1 month age group, having diarrhoea, in winter season.
