Abstract
In cryptosporidial infection, very scarce literature is available about periparturient pattern of oocyst excretion in goats and its implications in the epidemiology of disease in kids; thus the present investigation was done. Faecal samples (160) were examined from 20 pregnant goats, collected at weekly interval, commencing from 4 weeks before kidding up to 3 weeks after kidding. Faecal sample examination by Sheather’s floatation sedimentation technique followed by modified Ziehl-Neelsen staining technique revealed an overall positivity of 26.25% for Cryptosporidium oocysts. Prevalence of oocysts excretion was high around parturition and the number of oocysts shed oscillated between 20–400 oocysts/g (OPG) of faeces. Examination of 60 faecal samples of 20 kids born to studied goats from 1 to 3 weeks of age revealed 40% samples positive for Cryptosporidium oocysts and 65% kids became infected by the end of the 3 weeks. The OPG of kids ranged from 100 to 1,560. Molecular characterization by PCR-RFLP of 18S small subunit (SSU) rRNA gene showed that 73.80% and 26.19% goat samples, and 87.5% and 12.5% kids samples were positive for C. parvum and C. ubiquitum, respectively. The study indicated periparturient transmission of Cryptosporidium spp. from pregnant goats to their new born kids.
