Molecular and Serological Evaluation of Hantavirus in Wild Rodents in Kohgiluyeh and Boyer-Ahmad Province, Southwest of Iran

Abstract

Background: Hantaviruses are mainly transmitted to humans through the inhalation of aerosolized excreta from infect­ed rodent reservoirs. The present study was conducted to analyze the prevalence of hantavirus infection among rodents in the Boyer-Ahmad region.
Methods: A total of 52 rodents were captured in the Boyer-Ahmad region of Kohgiluyeh and Boyer-Ahmad Province during June to November 2014, using Sherman live traps. Blood and tissue samples were obtained from the heart and lungs, respectively.  Hantavirus Pool 1 "Eurasia" IgG and Pool 2 "America" ELISA IgG kits were used to detect IgG antibodies against both Old World and New World hantaviruses. Moreover, total RNA extraction was performed on the lung tissue, and a pan-hantavirus nested RT-PCR was conducted to detect hantavirus RNA.
Results: Meriones persicus was the most abundant species (n=25, 48%). The results of the ELISA showed that all the serum samples from the rodents were negative for antibodies against both Eurasian and American hantaviruses. Moreo­ver, no rodent tissue samples tested positive for the hantavirus RNA by the pan-hantavirus RT-PCR.
Conclusion: Although no hantavirus infection was detected in this study, the presence of hantavirus reservoirs in Koh­giluyeh and Boyer-Ahmad Province suggests that hantavirus circulation cannot be completely ruled out. Further studies with a larger sample size are recommended.
