Evaluation and investigation on the species of the host and the plague serology in 2008 in Guangdong Province

Objective To investigate the species composition and density of the host and the plague serological positive in historical epidemic area in Guangdong Province,and provide the scientific evidence for the preventive measures.Methods The rodents were caught by the live trap,and were identified the species,then calculated the density of them.plague antibody was tested with the serum agglutination.Results In 2008,1 699 rodents were collected from 12 counties in Guangdong Province.The total rodent densities were 7.93 % indoor and 3.76% outdoor respectively.The Primary rodents indoor were Rattus flavipectus with 36.43%,Suncus murinus with 33.44% and Rattus norvegicus with 30.13% respectively,the Primary rodents outdoor were Rattus rattoides losea with 47.29% and Bandicota indica with 37.74%.Plague antibody of 5 933 Spermophilus daurius serum were all negative.Conclusions The species composition of the host was stable,the density of the rodents was low too.The possibility of outbreak of plague is prevented in Guangdong Province,and the surveillance is necessary.
