Badi qat gardidani prosessi jinchi (avtogamiya) prosessi sporahosilshavi (sporogoniya) ogoz meyobad. Sporahoi Mikrosporidiyaho asosan bayzashakli kalonashon 2—10 mkm buda, ba boftai hujayravii hayvonhoi gizodeh, ba vositai rishtachai prujinamonandi khud dokhil meshavand. Mikrosporidiyaho dar bisyor hayvonho (mohiho, kirmaki abreshim, zanburi asal va g.) kasalii mikrosporidiozro ba vujud meorad. Beshtar az 100 namudi Mikrosporidiyaho paraziti bandpoyho meboshand. Alhol rozhoi dar muborizai biologii ziddi hasharoti zararrasoni khojagii qishloq harjoniba istifoda burdani onho tadqiq meshavad.
