Abstract:
To detect and phylogeneticaly analyze arenavirus carried by wild rodents in Ningbo ,China ,two pairs of degener‐ate‐primers were designed to amplify the S and L gene of arenavirus ,and then RT‐PCR was applied to detect arenavirus carried by rodents which captured from Ningbo port area .All 73 rodents samples were detected ,of which 12 Rattus norvegicus were positive ,an arenavirus virus strain named DX1401 were separated .The S gene amplified products of DX1401 was about 413 bp ,and the L gene was 1 204 bp .The phylogenetic analysis of S segments showed that DX1401 strain was in one branch of phylogenetic tree with Mobala virus strain ACAR3080 .The genetic distance to Mobala virus strain ACAR3080 was the closest , with the value of 0 .467 ;the phylogenetic analysis of L segments showed that DX1401 strain were in one group of phylogenetic tree with Lassa virus strain Josiah ,NL ,Z148 ,Bamba‐R114 ,Soromba‐R ,Nig08‐A37 ,Nig08‐A47 ,Mobala virus strain ACAR3080 ,Morogoro virus strain 13017/2004 ,Mopeia virus strain Mozambique ,and AN 21366‐BNI .The genetic distance to Mobala virus strain ACAR3080 was the closest ,with the value of 6 .953 .In conclusion ,the study confirmed the existence of arenavirus popular in wild rodents in Ningbo ,China .
