Experimental invasion of Strongyloides papillosus [Wedl, 1856] in sheep

Studies on the pathogenesis of strongyloidosis in sheep aged 6 to 8 months and infected with 10⁵ of invasive L₃ Strongyloides papillous Iarvae were carried out. A negative effect of the pathogenic form of the parasite on the sheep was found. More than 50% of the sheep died and the survived sheep revealed suppressed development, progressive wasting, a decreased number of erythrocyte, haemoglobin concentrations, haematocrite indexes and leukocyte counts.
