Phenotypic traits of inbred Biomphalaria glabrata lines that correlate with susceptibility to Schistosoma mansoni. Traits were measured in 12 mm snails. Trait values were calculated as a percentage of the highest mean of all the lines. (A) The four most susceptible inbred lines (i36, i93, i159, i163) have less than 40% of the highest average spread cell numbers (Sprd Hem) and low allograft inflammatory factor (aif) expression which is consistent among the lines. (B) Four resistant lines (i7, i31, i113, i156) with the lowest numbers of spread cells consistently expressed high peroxiredoxin 1 (prx 1) and similar mid-levels of aif and the inferred phox subunit (infPhox). (C) Three resistant lines (i84, i147, i170) with high numbers of spread cells showed mid to lower levels of expression in nearly all depicted genes.
