[The serogroup and serotype distribution of Leptospira in Sichuan Province from 1958-1987].
This paper summarized the serogroup and serotype distribution of 7,560 strains Leptospira in Sichuan province from 1958 to 1987. At present, Leptospira 16 serogroup and 35 serotype have been found. The Icterohaemorrhagiae group Lai type is the major and stable serogroup and serotype in patients. We have proved that Rodents insectivores and domestic animals are the main reservoir host. The former carries Icterohaemorrhagiae group and the latter carries Pomona group. The serotype carried on the reservoir animal Apodemus agrarius is mostly Icterohaemorrhagiae Lai and is the principal infection source of Leptospirosis in Sichuan province. In addition, this paper discussed the reason of main serogroup change, the possible role of frog as an infection source of Hebdomadis Leptospirosis.
