Abstract AR

في هذه الدراسة تم إخضاع 320 عينة إدرار للعزل و التشخيص استحصلت من مرضى يعانون من التهابات المجاري البولية.

عينات الإدرار قاعدية التفاعل كانت 86 عينة، و أعطت حصيلة 8 عزلات من بكتريا Corynebacterium urealyticum جميعها امتلكت نفس الخصائص الزراعية و البايوكيمياوية.

إن دراسة القابلية الأمراضية لبكتيريا Corynebacterium urealyticum تشير لقلة إنتاجها لعوامل الضراوة حيث كان أهمها إنزيم اليوريز و ينتج من قبل جميع العزلات أما قدرة Corynebacterium urealyticum على تكوين حصى الستروفايت الكلوي فأظهرت النتائج بأن كريستالات الستروفايت تكونت بعد مرور 24 ساعة من نمو البكتريا في عينة إدرار زرعي مختبري مقارنة مع عدم قدرة الـ E.coli على تكوين تلك الكريستالات في نفس الظروف المختبرية.

أخيرا تم دراسة قدرة مثبطات مضخة البروتون : الاومبرازول و اللانسوبرازول على التأثير على نمو البكتريا و قدرتها الأمراضية حيث وجد بأن التأثير التثبيطي كان معتمدا على الجرعة العلاجية بينما تأثر نمو البكتريا بصورة واضحة (p < 0.001) بزيادة تركيز الاومبرازول.

Abstract EN

Three hundred twenty urine samples were collected from patients suffering urinary tract affection.

Only alkaline sample were selected which formed 86 specimens yielded 8 isolates of Cory nebacterium urealyticum.

All the 8 isolates were identical regarding cultural characteristics and biochemical reactions.

Results of the studied virulence factors expression by Cory nebacterium urealyticum showed that urease was the most important factor in pathogenicity.

An experimental study was created to assess the ability Struvite stone formation by Cory nebacterium urealyticum during its growth in human urine; it was found that there was gradual increase in urine pH with associated elevation of ammonium ion concentration accompanied by bacterial growth and striated crystals which appeared grossly as a white precipitate at the bottom of the testing tube after an overnight incubation in human urine.

This observation was compared to the failure of E.

coli and control urine to increase the urine pH or ammonium concentration in sterile urine specimens, together with the inability form stupide crystals when incubated under similar experimental Conditions.

The effects of the proton – pump inhibitors : omeprazole and lansoprazole on growth and pathogenicity of Cory nebacterium urealyticum were examined, it was obvious that these compound markedly affected urease activity in a dose-dependent manner and the bacterial growth was significantly (p<0.001) inhibited by an increasing concentrations of omeprazole.
