Goblet and mast cell responses in the jejunum of four genera, Mesocricetus auratus (Syrian hamster), Phodopus campbelli, Cricetulus griseus (Chinese hamster), and Tscherskia triton, belonging to the subfamily Cricetinae, were examined after infection with Strongyloides venezuelensis. Parasite eggs became detectable in faeces of all four genera on Day 7. Faecal egg count peaked around Day 8 in C. griseus and T. triton and around Day 14 in M. auratus and P. campbelli. In M. auratus and P. campbelli, faecal egg production persisted over 40 days, whereas that in C. griseus and T. triton rapidly terminated within 14 days. In all four genera examined, goblet cell hyperplasia and mastocytosis were observed at the time of expulsion of S. venezuelensis. However, in the comparative study of all four genera, neither the degree of goblet or mast cell hyperplasia nor the phenotype of mast cells correlated to the rapidity of the expulsion of S. venezuelensis. On the other hand, the rapidity of expulsion closely correlated with the degree of sulphation of goblet cell mucins because two genera, C. griseus and T. triton, having highly sulphated goblet cell mucins showed faster expulsion of S. venezuelensis than the other two genera, P. campbelli and M. auratus, having less sulphated mucins. These results suggest that physicochemical nature of mucins is critical for the expulsion of S. venezuelensis from the subfamily Cricetinae.
