A Study on Leptospirosis in Bombay City

By M. N. LAHIRI (From the Haffkine Institute, Bombay) . After the first proven case of leptospirosis Jn the city of Bombay was reported by the writer (1941a), six more cases have been detected which could be proved positive _ either by serological methods or by the isolation of leptospirse. It may be emphasized that these positive cases do in no way represent the true incidence of the disease in the city, where only a few of the many cases that actually occur come under medical observation or are admitted into hospitals. Furthermore, the disease is sometimes likely to assume a very mild form with the result that some cases pass unrecognized, while a few more are wrongly diagnosed as one of the other types of jaundice.
