Further Studies On The Survival Time Of The Bovine Tubercle Bacillus In Soil, Soil And Dung, In Dung And On Grass, With Experiments On Feeding Guinea-Pigs And Calves On Grass Artificially Infected With Bovine Tubercle Bacilli, E. C. G. Maddock

Michigan Bovine Tuberculosis Bibliography and Database

IN a previous paper (Maddock, 1933) it was reported that when soil, soil and dung mixtures and dung were infected by adding fine emulsions of bovine tubercular material, virulent tubercle bacilli could be recovered after 178 days' exposure under field conditions. The experiments reported in the aforesaid paper were carried out in 1931, but it was felt that weight would be added to the results if the experiments could be repeated in a year of differing weather conditions.
