摘要

This is the first study on the prevalence of vector-borne zoonotic pathogens found in Rattus norvegicus ( R. norvegicus ) in urban areas of Tehran, Iran. Serological tests were used to detect IgG antibodies against Coxiella burnetii ( C.?burnetii ) and Rickettsia spp. using a commercial qualitative rat ELISA kit. The frequency of Streptobacillus moniliformis ( S.?moniliformis ) and Bartonella spp. was determined using a conventional PCR method. Molecular detection and characterization of Leptospira spp. were conducted using TaqMan real-time PCR based on lipL32 gene and SecY typing methods. A total of 100 R.?norvegicus rats were collected from five regions in Tehran, Iran, and investigated to determine their zoonotic pathogens. S.?moniliformis and Bartonella spp. were detected in 23 of 100 (23%) and 17 of 100 (17%) R.?norvegicus populations, respectively. The highest prevalence of S.?moniliformis and Bartonella spp. with similar frequency rates (n?=?6/20; 30%) was seen among the R.?norvegicus rats captured from the northern and southern parts of Tehran, respectively. Seroreactivity against C.?burnetii and Rickettsia spp. was detected in 4% and 1% of R. norvegicus , respectively. C.?burnetii. was identified only in one rat captured from the eastern part of Tehran. Results showed that Leptospira spp. was detected only in two rats, collected from the southern part (n?=?2/20; 10%) of Tehran. The secY typing method identified two different Leptospira species including L.?interrogans and L.?kirschneri. The results showed that urban rats might play an important role in transmission of zoonotic pathogens to humans.

Norvegicus检测到。 C.?Burnetii。仅在一只从德黑兰东部捕获的一只大鼠中确定。结果表明，Leptospira SPP。仅在两只大鼠中检测到，从南部（n？= 2/20; 10％）的德黑兰收集。 SECY键入方法确定了两种不同的百分之叶物种，包括L.?interrogans和L.?kirschneri。结果表明，城市大鼠可能在对人类传播到人群的情况下发挥着重要作用。
