Leptospirosis. With Special Reference to the Existence of Spirochaetosis Ictero-Haemorrhagica, or Weil's Disease, in the Andaman Islands

چکیده
TiiK term " leptospirosis" means infection by that group of spirochetes known as Leptospira. For many years there was much discussion as to whether spirochetes should be classed among protozoa or among the non-protozoal bacteria. Many workers, basing their arguments mainly on Schaudinn's classical paper published in 1905 (i), claimed that they were protozoa: on the other hand, there is strong evidence that they are true bacteria, e.g. (1) Their nuclear structure is like that of a bacillus; (2) They divide by transverse fission,?as do bacteria but not protozoa; (3) Their rate of multiplication resembles that of bacteria more than that of protozoa; (4) Their serological and immunological reactions resemble those of bacterial, not protozoal, infections.

A Note upon an Interesting Serological Type of Leptospira in the Andamans

They further showed that the type strain CH11 was unique in that it was serologically distinct from several strains of leptospirse isolated in different parts of the w...
