Isolation of a leptospire belonging to serogroup tarassovi.

Abstract Extract Sir, — The leptospiral serovars that have been cultured in New Zealand are pomona, copenhageni, ballum and hardjo. (Anon., 1951; Kirschner and Gray, 1951; Anon., 1967a; Lake, 1973, respectively.) Serological evidence of serovar tarassovi has been published (Russell and Hansen, 1958) but it is believed that until now no members of this serogroup have been isolated in New Zealand.
