Objective To investigate Hantavirus(HV) infection of captured rodents at Nansha ports and provide a scientific basis for the control of rodents and rodent-borne diseases. Methods During May 2013 to April 2014, surveillance of the rodent carriers was performed in 7 coastal harbors in Nansha. The rodents were collected using rat cages and clamps. Lung samples were taken for HFRS viral testing. HV genotype was analyzed using Real-time RT-PCR. Results A total of 538 rodents were captured, including 6 species Suncus murinus, Rattus norvegicus, R. tanezumi, Bandicota indica, Mus musculus, R. losea, among which S. murinus was the predominant group, accounting for 53.16% (286/538). Total of 538 samples were tested, the positive rate of HV was 2.60%(14/538). Nucleotide sequences analysis showed that the virus detected belongs to the Seoulvirus type. Conclusion The HV was carried by rodents at Nansha ports. Surveillance for hemorrhagic fever with renal syndrome among rodents and the control of rodents should be implemented.

Objective　To review Hyalomma excavatum Koch, which was first captured from the Italian leather at Nansha port, Guangzhou, China, and to provide reference for inspection and quarantine work at the port. Methods　The adults of H. excavatum were characterized based on specimens and the relevant literature on Ixodidae. Hyalomma excavatum was further compared with closely related species, H. anatolicum. Results　Hyalomma excavatum was intercepted from imported Italian leather. This was the first time that H. excavatum had been discovered in foreign freighters. Hyalomma excavatum was morphologically characterized in this study. Comparison was made between H. excavatum and H. anatolicum in terms of taxonomy, biology, and importance in disease transmission. Conclusion　There is a high risk that exotic ticks are imported from goods. More attention should be paid and strict quarantine supervision should be carried out.
