    هل تعلمي اختي العزيزه ما المشكله !
    الفطريات بالذات لا تعلم من خلال الكتب والمراجع, الا من خلال الممارسه.
    لكن الاساس هو معرفه الامور الاساسيه ومن ثم البدأ بالتشخيص

    فكرة رائعة

    وبداية ان شاء الله تكون موفقة

    بحاجة كبيرة لمعرفة الفطريات الطبية بشكل اكبر

    كثير من الجامعات تهتم بالفطريات النباتية على حساب الفطريات الطبية

    حتى المختبرات الطبية لا تولى اهتمام كبير لهذا المجال


    وفقك الله اختى الكريمة
