Occurrence And Importance Of Enteric Protozoan Infections On Different Sheep Farms In District Swat - 2005

A study was conducted to determine the prevalence of various enteric protozoan infections in sheep. A total of 225 fresh faecal samples were collected from different sheep farms in District Swat N.W.F.P. These animals belonged to three different age groups i.e. Group I (up to 6 months of age), Group II (7-12 months of age) and Group III (above 1 year of age). Faecal samples were processed for the detection of Eimeria spp. oocysts, Giardia cysts, Cryptosporidium oocysts and other parasites by three different techniques. By Direct smear method, Sheather,s sugar flotation and zinc sulphate flotation technique. A total of faecal samples found positive for Eimeria oocysts 63 (28%), Giardia cysts 35 (15.55%), Cryptosporidium oocysts 16 (7.11%) and mixed parasitic infection 58 (25.77%). Data recorded for various protozoan infections indicated that prevalence rate in Group-I (Eimeria 37.33%, Giardia 22.66% and Cryptosporidium 12%) was higher than the Group-II (Eimeria 28%, Giardia 16% and Cryptosporidium 3%) and Group-III ( Eimeria 18.66%, Giardia 8% and Cryptosporidium 5.33%). Prevalence rate was also higher in diarrhoeic animals (Eimeria 35.71%, Giardia 23.80% and Cryptosporidium 16.66%) than the non diarrhoeic animals (Eimeria 26.22%, Giardia 13.66% and cryptosporidium 4.91%). A large number of faecal samples (25.77%) were found positive for various other parasitic infections. No significant difference was noted in males and females. Results of this study indicated wide spread prevalence of parasitic diseases in sheep population and mostly young animals were found to be infected by different protozoan parasites.
It can be concluded that enteric protozoan infections in sheep can be controlled through improved managemental practices, hygienic measures and avoidance of overcrowding the animals.
