Formation of sulfhydryl groups in the walls of Eimeria stiedai and E. tenella oocysts subjected to in vitro excystation

Eimeria stiedae or Eimeria tenella oocysts were incubated in aqueous cysteine (cysHCl) under carbon dioxide, aqueous cysHCl under air, water under CO2 or water under air, and analysed for sulphydryl (-SH) groups. The cysHCl-CO2 treatment produced more -SH groups than the other treatments and was effective in allowing activation of intact and sodium hypochlorite (NaOCl)-treated E. stiedae oocysts as well as NaOCl-treated E. tenella oocysts.
