Rodents are mammals that comprise more than 2000 species and approximately 30 families. There are many morphological and ecological differences among them as variations in their shape, size, weight and habitat. In addition to significant economic losses, rodents have a major role in the dissemination of infectious diseases caused by viruses, bacteria, parasites or other micro-organisms. Rodents are important reservoirs of diseases which have been observed in many cities of Iran provinces especially along Caspian Sea border to Alborz Mountain. The aim of this study is to assess the geographical distribution of rodents in three provinces of northern part of Iran as reservoir of potential endemic infectious diseases. Rodents in 10 major parts of each of the three provinces of Mazandaran, Gilan and Golestan, northern Iran were collected and a total of 404 rodents were trapped alive. They were determined by the key characteristics such as gender, genus, species, different locations and topological situation. Statistical analysis was performed to characterize the study sample and to correlate all variables and parameters. The distribution frequencies of three, five and six genera of rodents were identified in Mazandaran, Gilan and Golestan provinces respectively. The overall distribution frequency of eight genera of rodents in the three provinces were identified as (67.3%), (13.6%), (13.9%), (1%), (0.3%), (2.5%), (0.7%) and (0.7%). The results of this study determined the geographic distribution of the rodents in the three northern provinces of Iran. It is indicated the association of various distribution and diversity of rodents with provincial location. The overall distribution frequency of eight genera of rodents was recognized in the above three provinces geographical locations. This study confirms epidemiological distribution of various rodents as potent reservoirs for infectious diseases, such as leptospirosis, salmonellosis, tularemia, leishmaniasis, in the three provinces.
啮齿动物是哺乳动物，包括2000多种物种和大约30个科。它们在形态和生态上存在许多差异，如形状、大小、体重和栖息地的变化。除了造成重大经济损失外，啮齿动物在传播由病毒、细菌、寄生虫或其他微生物引起的传染病方面也起着重要作用。啮齿动物是疾病的重要宿主，在伊朗许多省份的城市都有发现，特别是沿着里海沿岸至阿尔伯兹山脉一带。本研究的目的是评估伊朗北部三个省份作为潜在地方传染病宿主的啮齿动物的地理分布。在伊朗北部的马赞德兰省、吉兰省和戈勒斯坦省的10个主要地区收集了啮齿动物，共活捉了404只啮齿动物。通过性别、属、种、不同地点和地形等关键特征对它们进行了鉴定。进行了统计分析以描述研究样本的特征，并关联所有变量和参数。分别在马赞德兰省、吉兰省和戈勒斯坦省确定了三种、五种和六种啮齿动物属的分布频率。这三个省份中八种啮齿动物属的总体分布频率分别为（67.3%）、（13.6%）、（13.9%）、（1%）、（0.3%）、（2.5%）、（0.7%）和（0.7%）。本研究结果确定了伊朗北部三个省份啮齿动物的地理分布。表明了啮齿动物的各种分布和多样性与省份位置的关联。在上述三个省份的地理位置确认了八种啮齿动物属的总体分布频率。本研究证实了各种啮齿动物作为钩端螺旋体病、沙门氏菌病、兔热病、利什曼病等传染病潜在宿主的流行病学分布情况。
