Fig. 2From: Molecular insights into the heat shock proteins of the human parasitic blood fluke Schistosoma mansoniPhylogenetic tree revealing the evolutionary history of Schistosoma mansoni HSPs. The evolutionary history of the HSP 10, 40, 60, 70 and 90 families was inferred by neighbour-joining method analysis [74]. Evolutionary distances were computed using the Poisson correction method [75]. The analysis involved 54 amino acid sequences (one each of HSP 10 and 60, eleven of HSP 70, three of HSP 90 and 38 of HSP 40); one HSP 70 member was excluded as it contained significant gaps in the alignment. The analysis (unrooted circular tree) was conducted using Molecular Evolutionary Genetic Analysis (MEGA) X [76]Back to article page
