Schistosomula of Schistosoma Mansoni and Schistosoma Margreboweiein the Mouse Liver; a Histological Study

The histo-morphological developmental changes in schistosomula of two groups, Schistosoma (S) mansoni and S. margreboweie inside the liver of definitive host mice was studied at Days post infection (DPI) 7, 10, 14, 21, 28, 35 and 42.In histologically divisions schistosomula groups, S. mansoni and S. margreboweie appeared on 21, 28 and 35 DPI and 10, 14, 21, 28, 35 and 42 DPI respectively in the mice liver. According to the results in branches of hepatic arteries and veinsthe number of S. mansoni and S. margreboweie was six and twelve respectively. At 14 DPI, schistosomula group S. margreboweie was divided into three regions, the thin anterior, wide middle and thin posterior regions. Afterwards DPI 35 schistosomula group S. mansoni was conflicted at middle body region, noticeable substantial musculature nearby the ventral sucker as well as an enlargement in gut caecum was observed. Both groups, Schistosoma (S) mansoni and S. margreboweie mean and standard deviation remained 128.41±22.002 μm and 91.00+-32.41μm. The variance in body diameter of both groups, Schistosoma (S) mansoni and S. margreboweie were statistically analyzed and found to be significantly different. (P 0.4841).
