ABSTRACT

We investigated the situation of leptosperosis infection among patients with fever in Hainan Province in China.Blood samples of patient from Hainan Province in the year of 2015 were detected for Leptospira by microscope agglutination test (MAT),enzyme-linked immunity test (ELISA) and polymerase chain reaction (PCR),respectively.Results showed that 179 blood samples of patients with fever were found,and microscope agglutination test detected 40 positive samples,with a infection rate of 22.35％.The infection rate was 21.65％(21/97) for male and 23.17％(19/82) for female.Seven groups of bac teria were found including Leptospira serogroup icterohemorrhagie,ballom group,autumralis group,pomona group,grippotyphosa group,Sejroe group and Batavia group.Thirty-eight samples were tested positive by ELISA,with a positive rate of 21.23 ％,in which six samples were IgM positive (detection rate =3.35 ％) and 32 samples were IgG positive (detection rate=17.88 ％).Serological detected with MAT and ELISA methods results were consistent and that were tested negative by PCR.Results of our study supported the presence of Leptospira infection infection among the patients with fever of unknown origin (FUO) in Hainan Province.The main types are Leptospira serogroup icterohemorrhagie.
