[The distribution of leptospirae in the icterohaemorrhagiae serogroup]

The capacity of leptospiras to get acclimated in the organism of unusual hosts has been studied. Cultures of Icterohaemorrhagiae from musquashes, house mice and field voles have been isolated of leptospirosis sources under intensive epizootics among rats. A possibility to reproduce Leptospira carrying by the cultures of leptospirae of serogroup icterohaemorrhagiae in musquashes and water voles has been shown. One can conclude that under icterohemorrhagic leptospirosis musquashes and water voles can take the part of additional source of infection but they cannot independently preserve leptospirae in nature as a biological species grey rats being their main hosts.
