What is The Survival Of Leptospira (spirochæta) Icterohæmorrhagiæ In Nature; Observations Concerning Microchemical Reactions And Intermediary Hosts about?
1. __Leptospira icterohæmorrhagiæ__ is unable to grow in the urine, either with or without the addition of suitable culture ingredients, the acidity of the urine being detrimental to the growth. It survives less than 24 hours, unless the urine is neutralized or slightly alkalized, when the period of survival is somewhat longer. If suitable nutrient ingredients are added to the neutralized or slightly alkalized urine, the organism is able to grow for about 10 days, after which multiplication ceases. 2. Feces from normal or jaundiced persons destroy __Leptospira icterohæmorrhagiæ__ within 24 hours when a rich culture is added and the mixture allowed to stand at 26°C. The addition of blood serum and corpuscles does not prevent the destruction of the organism. Autoclaved specimens and filtrates of unheated feces do not constitute a suitable medium in which to keep the organism alive for any length of time, but the addition of blood corpuscles and serum in adequate quantities renders them fairly satisfactory as media. Under natural conditions __Leptospira icterohæmorrhagiæ__ cast off in the feces cannot survive more than 24 hours. 3. Polluted water, sewage, and soil will not serve to ke
