xenoma造句

• Rupture of the xenoma may also result in dispersal of the infectious spores.
• The host can eventually destroy the xenoma.
• While it is generally accepted that the xenoma prevents spread of the parasite throughout the host organism, it is not entirely accurate.
• In the most advanced cases of parasitism the microsporidium rules the host cell completely and controls its metabolism and reproduction, forming a xenoma.
• Specific environmental stimulation causes the spore to discharge the polar tube which penetrates the xenoma membrane and provides an exit route for the sporoplasm.
• As the species that cause xenomas are spore-forming, it is possible that their spores may release their sporoplasms which penetrate the xenoma wall, infiltrating and infecting surrounding cells.
