چکیده

پیشینه: لپتوسپیروز یک بیماری مشترک بین انسان و دام با پراکندگی زیاد در کره زمین است و گونه‌های لپتوسپیرا عامل این بیماری هستند. پستانداران می‌توانند به عنوان میزبان مخزن باکتری‌ها عمل کنند، با این حال جوندگان به ویژه موش‌ها به عنوان مهم‌ترین مخزن، عمدتا برای سرووار لپتوسپیرا اینتروگانس اکیتروهموراژیه شناخته شده‌اند. در الجزایر، اطلاعات کمی در مورد گردش باکتری لپتوسپیرا در انسان و حیوانات از جمله جوندگان در دسترس است. هدف: مطالعه ما با هدف آشکار کردن اهمیت موش‌ها به عنوان میزبان مخزن گونه‌های لپتوسپیرا در شهر البلیده، الجزایر انجام شد. روش کار: در مجموع 100 موش صحرایی شامل 88 عدد Rattus norvegicus و 12 عدد Rattus rattus گرفته شدند و سرم آن‌ها از نظر آنتی‌بادی توسطMicroscopique Agglutination Test (MAT)  آزمایش شد و کلیه‌ها و کبد آن‌ها در محیط Ellinghausen، McCullough، Johnson Harris (EMJH) کشت شدند. نتایج: مطالعه ما شیوع سرمی 43%              (95% CL: 33.3-52.7%) را نشان داد. شایع‌ترین سروگروه آلوده کننده Icterohaemorrhagiae 11% (100/11) و بالاترین تیتر مربوط به سروگروه Canicola 1:250 بود. تفاوت آماری بین دو جنس، طبقات سنی و گونه موش‌ها مشاهده نشد، اما به نظر می‌رسد موش‌های صید شده در مناطق شهری بیشتر از موش‌های صید شده در مناطق روستایی آلوده هستند. کشت اندام وضعیت ناقل باکتری را با شیوع 8% تایید کرد. نتیجه‌گیری: بررسی ما نقش موش صحرایی را به عنوان میزبان مخزن لپتوسپیرا تایید می‌کند و داده‌های ارزشمندی را در مورد اپیدمیولوژی لپتوسپیروز در این حیوان ارائه می‌دهد. بنابراین، کنترل جمعیت موش در شهر البلیده برای جلوگیری از شیوع لپتوسپیروز در انسان و سایر حیوانات مهم است.
