التشخيص الجزيئي لبكتريا Enterobacter cloacae وStutzerimonas stutzeri ودراسة تأثير بعض المستخلصات النباتية
الصفحات
243-260الملخص
يعتقد ان جيوب اللثة توفر بيئة مناسبة لتكاثر مجموعة متنوعة من الكائنات الحية الدقيقة. يكمن الخطر في ظهور سلالات جديدة من البكتريا مقاومة للمضادات الحيوية، مما يؤدي الى ابطاء عملية العلاج او الاستئصال الجراحي لجيب اللثة. الغرض من هذه الدراسة هو تحديد البكتريا الموجودة في جيوب اللثة باستخدام تقنية PCR لجين 16S rRNA.بالإضافة الى اختبار الحساسية للبكتريا المكتشفة، وكذلك تأثير المستخلصات النباتية على نمو هذه السلالات. تم تسجيل خمس سلالات بكتيرية جديدة في، NCBIبما في ذلك Stutzerimonas stutzeri وStaphylococcus aureus و Enterobacter cloacae. كانت جميع السلالات المشخصة حساسة Augmentin Ciprofloxacin ولكنها مقاومة Cephalothin. لم يظهر Cefixime Bacitraci فعالية ضد 90% من السلالات. في حين كان معدل مقاومة Amoxicillin 50%. أظهرت جميع السلالات مقاومة لمستخلصات الكركم والاوريجانو بتراكيز 100و200 ملغم /مل، باستثناء S. aureus FKZEW99، الذي كان عرضة للاوريجانو عند 200 ملغم/مل. اختلفت استجابات السلالات المشخصة لمستخلص القرنفل من حيث الحساسية والمقاومة. يؤدي الافراط في استخدام المضادات الحيوية الى ظهور سلالات بكتيرية جديدة مقاومة لمجموعة من العلاج.
