Hog cholera and swine plague in South Africa, A. 'l"iii:ii.i:i{ {t'orlsclir. \'<i. 

 If I/!/., 'i U9li(!). Xo. a, 1)1). r21-I2S). — As the result of a long-continued study 

 of tliese diseases in South Africa, tiie author conchules that Ii(tcilliii< .sh/.sy'p^/ch.s 

 as it occurs in Soutli Africa is practically identical with tiie usual form ob- 

 served in Europe. The patliological lesions i)roduced in Sotitii Africa are also 

 the same as tlu»se described by European invest ii^a tors. 



The author i)roduced an infection in -1 out of 7 hogs which were fed large 

 (luantities of the bacteria, and suggests that the large percentage of infection 

 may have been due to llic presence of intestinal worms. In nearly all cases 

 hog cholera is associated with swine plague in South Africa. In fact, the author 

 never oi)ser\'ed but one case of swine plague in which 7>. siiisciiliciis was demon- 

 strated and in which hog cholera was not present. A])parently there is no 

 epizootic in South Africa due to Ji. .sai.septicus, but the common infectious hog 

 disease is associated with hog cholera, which gives B. stiiycpticiis an oppor- 

 tunity to infect hogs. 



Is the virus of swine plague and hog cholera filterable? K. Ostebtao 

 (Berlin. Ticn'irztl. Wclnis'-hr., IV06. No. ,?//, />/>. 62d-(x2(J). — In experiments in the 

 filtration of the virus of swine plague the results were negative in some cases 

 and positive in others. Where positive results in infection took place it appeared 

 that the infection was due to some other agent than the organism of swine 

 plague. 



The author also carried on some experiments in filtering the virus of hog 

 cholera to determine wh(>ther this virus was infectious as showu to be in some 

 cases by the Bureau of Animal Industry of this Department. In the first test 

 the filtered virus was not infectious, but when material from this country was 

 used in the experiments it was found to be virulent after filtration. The author 

 expects within the near future to develop a practical system by means of which 

 hog cholera may be controlled. 



The relation of Bacillus pyogenes suis to swine plague, F. Koske (Arb. K. 

 G.^iuHit.'<(iiiit.. I'l (1006), No. 2. PI). lHl-195). — Numerous investigators have at- 

 tempted to <letei-mine the exact relationship of B. pyof/oics .^iiis to swine plague. 

 The literature iclaling to this subject was briefly reviewed by the author. 'Phe 

 organism in question was cultivated on a number of nutrient media and notes 

 are given on the behavior of the ba<'illus. The organism is killed by subjection 

 to a temperature of 55° C. for 20 minutes or by treatment with a 1 per cent 

 corrosive .suiilimate solution for 1 minute, a 3 per cent cresol solution for 1 

 minute, or a 5 per cent carbolic acid solution for li minutes. 



Inoculation experiments were made on laboratory animals and pigs, the 

 bacteiial cultures being injected into the blood, lungs, body cavity, and muscuia- 

 ture, or l)eing given in feeding experiments and l)y inhalation. Any of these 

 methods of inoculation may cause the death of some of the experimental ani- 

 mals under symptoms of acute sei)ticemia. but in most cases there is only a 

 local abscess formation. In no case was there a development of the usual symp- 

 toms of swine plague in the lungs. Accordingly the author concludes that B. 

 piioiicncft suis may cause general septicema or pyemia or local abscesses, but is 

 not the true cause of swin(> jilague. 



Toxic phenomena observed as a result of injecting dead glanders bacilli
