Natural Leptospiral Infection in the Rat Population of Calcutta
نویسنده
چکیده
Soon after the discovery of the causal organism of Weil's disease by Inada and Ido (1915), the proof was forthcoming that rats which harbour the organism in their kidneys are responsible for the dissemination of the disease. The presence of natural leptospiral infection in wild rats was first recognized by Miyajima in Japan [Walch-Sorgdrager (1939) ]. Since then it has been found to exist in many parts of the world, even in areas where leptospiral infection in man is unknown. For example, in New York the incidence of natural infection in rats is enormously high (about 60 per cent), but no ease of the disease among human beings has so far been recorded. In Calcutta Knowles (1928) examined 180 rats, but none were found infected.
