688 EXPERIMENT STATION EECOKD. 



The autopsies with the above animals brought out the fact that no lung 

 lesions were produced in the animals inoculated originally subcutaneously by 

 inoculating intravenously thereafter, but a tuberculous infiltration could be 

 noted in the mediastinal glands or bronchial glands, or in both. Varied 

 results in regard to local subcutaneous foci in the subscapular gland were 

 obtained. 



The author draws attention to the fact that such an artificial immunity is 

 only relative and not absolute. Of the animals treated with bovine tubercle 

 bacilli 50 per cent gave complete success (macroscopically no lesions), 25 per 

 cent relative success (those which showed circumscribed lesions being caseocal- 

 careous either in one or few glands), and 25 per cent failure (extensive tubercu- 

 losis, which was sometimes fatal). The controls in this group gave of com- 

 pletely infec'ted animals 63.6 per cent, partly infected 27.2 per cent, and no 

 infection 9.2 per cent. 



With animals immunized with human tubercle bacilli 42.1 per cent were 

 completely successful, 42.1 per cent relatively successful, and 15.8 per cent 

 failures. The controls gave com])lete infection in 12.5 per cent of the cases 

 and partial infection in 87.5 per cent. 



Immunization of bovines ag-ainst tuberculosis, A. Weber, Fitze, and Iorn 

 (Tuberh-ulose Arb. K. GsiuUitsamt., 1910, Ao. 10, ijp. 157-199; abs. in Molk. Ztg. 

 [HUdesheim], 2J, {1910), Xo. 35, p. 6^9).— The results of tests extending over a 

 period of 3 years with bovovaccination showed it to be without danger to the 

 animal vaccinated, but the results obtained were not considered remarkable. 

 In a barn freed from tuberculosis, according to Bang's method, tuberculosis 

 spread as quiclvly among the vaccinated animals as amongst the unvaccinated 

 ones. Tauruman vaccination, according to Koch and Schlitz, apparently 

 yielded good results in view of the fact that the calves from a herd which 

 previously showed 95 per cent of tubercular animals with tuberculin was 

 found on autopsy 2 or 3 years after vaccination to be free from tuberculosis. 

 Attention is called to the possible danger of utilizing human tubercle bacilli 

 for vaccination purposes. 



The value of lymphatic tissue extracts in regard to the evolution of 

 experimental tuberculosis, S. Livierato {Vcntbl. Bakt. [etc.], 1. Abt., Orig., 

 ftJf {1910), A'o. .//, pp. 332-337). — This work with normal, scrofulous and tuber- 

 cular lymphatic glands shows that animals treated with tubercular and scrofu- 

 lous lymphatic gland extracts lived up to a period of 4 months after infection, 

 while those treated with normal lymphatic gland extracts always died within 

 60 days, but lived 20 days longer than the control animals. The best results 

 were thus obtained with tuberculous gland extracts. The lesions in the animals 

 treated with normal lyuii)hatic gland extract were pronouncedly tubercular, 

 while those treated with the scrofulous and tuberculous gland extracts were 

 only sparingly so. 



Feeding mice with healthy meat, A. Schellhorn {Ccntbl. Bakt. [etc.], 1. 

 AM.. Orifi.. 5', (1910), A'o. J. pp. ii28-J,50). — The author fed mice with healthy 

 germ-free meat, with the result that 50 per cent of the animals died in from 

 3 to 5 days. With mice fed on meat containing streptococci, 10 per cent suc- 

 cumbed only after 5 days, and 10 per cent of those fed on an 8-week old para- 

 typhoid culture died after 26 days. One hundred per cent of the animals fed 

 on the fresh paratyphoid bouillon culture died within 4 to 5 days. 



The results thus show that not much reliance can be place<l on the mouse 

 feeding method for determining the fitness of meat for consumption.
