Abstract AR
الأهداف : تحديد نوع الرجاثيم المسبةة لالتهاب الأذن الوسطى التقيحي المزمن و معرفة نمط حساسيتها للمضادات الحيوية ليتسنى معالجة الالتهابات بالمضاد الحيوي المناسب أثناء انتظار نتيجة الزرع البكتيري و اختبار حساسية البكتيريا للمضاد الحيوي.
منهجية البحث : أجريت هذه الدراسة التطبيقية في مستشفى الفرات الأوسط-قسم الأذن و الأنف و الحنجرة في محافظة النجف الأشرف للفترة من كانون الأول 2010 إلى نيسان 2011 حيث تضمنت الدراسة أخذ 51 مسحة من إفرازات الأذن للمرضى المصابين بإلتهاب الأذن الوسطى التقيحي المزمن و إجراء الزرع البكتيري و اختبار حساسية البكتيريا للمضادات الحيوية باستخدام التحاليل المختبرية المعتمدة علميا و إجراء مقارنة إحصائية بين الجراثيم المسببة من حيث نوعها و كثرة ترددها و مدى حساسيتها للمضادات الحيوية المختلفة اعتمادا على النسبة المئوية.
النتائج : أظهرت الدراسة أن نسبة إصابة الإناث بالمرض أكثر من نسبة إصابة الذكور بمقدار 1:1.8 و الأعمار الأكثر تعرضا للإصابة هي التي تقع بين 3 أشهر-15 سنة كما بينت أن البكتيريا الأكثر شيوعا في إحداث التهاب الأذن : الوسطى التقيحي المزمن هي Staphylococcus aureus موجبة الكرام تليها .aeruginosa Pseudomonas
Abstract EN
Objectives : the aim of this study was to determine the most frequent bacteria that cause chronic supportive otitis media(CSOM) and their sensitivity to various antimicrobials so that an appropriate therapy can be started promptly while awaiting the results of the culture and sensitivity of the isolate to various antibiotics.
Methodology : this study was conducted at Afloat teaching hospital in Najaf city at the ear-nose-throat (ENT) department from December 2010 to April 2011.
The swab was taken from ear discharge before starting the antibiotics and cultured on Mac Conckey agar (Oxoid, England) and blood agar (Hi Media, India).
Gram positive bacteria were identified on the bases of colony morphology.
Gram staining, catalase test and coagulase test while the Gram negative bacteria were identified by oxidase test and API 20E (API Bio Merieux, France).
The sensitivity of the isolates to various antibiotics was tested by Kirby Bauer disk diffusion technique.
Results: The study showed that females are more prone to get the infection than males in a ratio of 1.8 : 1 and the frequent ages liable for infection lie between 3months–15 year, also it revealed that the gram negative bacteria were more frequent in causing the infection than gram positive bacteria in a ratio of 2.64 :1 and Pseudomonas aeruginosa was the most frequent species that causes CSOM then Staphylococcus aureus and Proteus mirabilis.
Pseudomonas aeruginosa was more sensitive to ciprofloxacin than to gentamicin, Staphylococcus aureus also showed more sensitivity to ciprofloxacin than gentamicin, while Proteus mirabilis had the same degree of sensitivity to those 2 antibiotics.
Conclusions : 1- Children are more prone to be infected with CSOM because of their small Eustachian tube and low immunity.
2- Gram negative bacteria were more common in causing the infection than gram-positive bacteria in this study.
3- Pseudomonas aeruginosa was the most frequent bacteria that cause CSOM then Staphylococcus aureus and Proteus mirabilis.
4- Pseudomonas aeruginosa was more sensitive to ciprofloxacin than to gentamicin despite the fact that gentamicin is known to be effective against gram negative bacteria including Pseudomonas aeruginosa propably because of antibiotic miss use and genetic mutation of Pseudomonas aeruginosa.
