380 EXPERIMENT STATION RECORD. 



old cultures of the bovine tubercle bacillus grown upon potato and heated for 6 

 hours at 05° C. The vaccine was administered to guinea pigs as an emulsion 

 in installments of 15 cc, with the aid of a tube 15 cm. long and intcf the large 

 Intestine. A few drops of laudanum were given at the same time. To deter- 

 mine whether immunity was established either subcutaneous injections of viru- 

 lent tubercle bacilli were given, or the virulent bacilli were introduced into the 

 alimentai-y canal with an oesophageal sound. 



All of the guinea pigs receiving virulent cultures were later found to be 

 tuberculous. The "injection of the vaccines seemed to be well borne by the 

 guinea pigs, and did not produce any particular symptoms. 



In regard to immunizing' bovines against tuberculosis with von Behring's 

 method, Dammann (Arch. Wiss. u. Prakt. TierheUk., 3S (1911), No. 1-2, pp. 

 44-98). — In this report, which continues previous worli ^ the conclusion is 

 reached, on the basis of numerous tests with animals kept under ordinary farm 

 conditions, that von Behring's bovo-vaccination method alone does not give 

 calves a positive protection against either artificial or a later natural infection 

 by the tubercle bacillus. 



A contribution to von Behring's bovo-vaccination, W. Ebbxing (Med. Krit. 

 Bl. Hamburg, 1 (1910), No. 2, pp. 81-89; abs. in Ztschr. Imtnumtatsf. u. Expt. 

 Tlier., II, Ref., 3 (1910), No. 9, pp. 904, 905).— This is a report of the result of 

 vaccinating 4,261 calves according to von Behring's method, conducted under 

 ordinary farm conditions but with the necessary antiseptic precautions. The 

 author believes the immunity thus derived to be only relative and not absolute. 

 Sixty of the vaccinated animals were brought to section, and out of these only 



5 per cent showed tuberculosis. 



The clinical aspect of Johne's disease and the avian tuberculin test, G. P. 

 Male (Vet. Rec, 23 (1911), No. 1192, pp. 723-726) .—After describing the eti- 

 ology, symptoms, and lesions of this disease the author gives his results in 

 diagnosing and differentiating it with avian tuberculin from diseases in which 

 the diarrhea is due to other parasites or other causes. 



In all 55 animals were tested (2 herds), some of which came to slaughter. 

 Almost all which were submitted to a necropsy showed evidences of Johne's 

 disease. The only way of eradicating the disease seems to be on the basis of 

 the avian tuberculin test and the isolation of the reacting animals whether 

 they show symptoms or not. In regard to therapeutic measures, the author 

 obtained the best results with cyllin given in diluted dram doses once or twice 

 daily. 



Etiology, prophylaxis, and therapeutics of parturient paresis, W. Otte 

 (Berlin. Ticrdrztl. Wchnschr., 27 (1911), No. 24, PP- 429-4S3). — A discussion in 

 regard to the etiology, pathology, and treatment of this condition, which the 

 author believes to be one of asphyxia (asphyxia puerperalis). 



The treatment recommended consists of oxygen inhalations through a mask, 

 or Introudcing the gas directly and slowly into the jugular vein and under the 

 skin. This is aided by injections of caffein-sodium salicylate. Where one is 

 forced to use an air infusion, fresh air is pumped into the mammary gland and 

 after 10 minutes it is allowed to escape and the gland again inflated. As soon 

 as the condition of the animal improves, she is placed on her other side and 

 later transferred to a well-ventilated room. She is not milked until from 5 to 



6 hours after this treatment.
