Insulin immunostaining of pancreatic islet cell from MLDS-treated mice. (a) Immunostaining of insulin in islets from BALB/c mice, insulin immunostaining in pancreatic islets of different uninfected (normal), uninfected and MLDS-treated mice (STZ), or T. crassiceps-infected MLDS-treated mice (STZ/Tc). Mice () were sacrificed 6 weeks after the initial injection of MLDS and pancreata were processed for immunohistochemistry to specifically detect insulin. (b) Same as (a), just the sections belong to C57BL/6 mice. Note the lack of insulin staining in uninfected MLDS-treated mice. Magnification 400.
