VETERINARY SCIENCE AND PRACTICE. 



Trichinosis in Germany, C. W. Stiles and A. Hassall (f^. *S'. Dept.Agr., Bureau 

 of Aniiiud LidK.-<tr>i Bui. 30, pp. 211). — The purposes of the investigation as reported 

 in this ])ulletin were to ascertain the value of microscopic examination of pork prod- 

 ucts in Germany, to determine whether cases of trichinosis had been definitely traced 

 to American j)ork bearing a stamp of inspection from this Department, and to inves- 

 tigate the l)asis for charges made in Germany against American meats. In the bulle- 

 tin the following subjects are discussed: The history of the discovery of trichinosis, 

 life history of the parasite, preventive measures, trichinosis as an international ques- 

 tion between Germany and America, local regulations regarding trichin;e in Germany, 

 number of trichina inspectors, the expense of such inspection, and statistics on the 

 amount of American pork imported into Germany for the years 1892 to 1898. 



In addition to this general discussion the report contains a detailed statistical review 

 of trichinosis in Germany during the years 1881 to 1898, inclusive. In this review the 

 conditions in Prussia, Saxony, Bavaria, Brunswick, Bremen, Alsace-Lorraine, Ham- 

 ] )urg, and Liibeck are considered separately. Special attention is given to the subject 

 of European cases of trichinosis of alleged American origin. Translations are pre- 

 sented of an article by Rudolph Virchow on American trichina?, and by Bouley on 

 importation of salted pork of American origin, and an extended bibliography on the 

 sul)ject of trichinosis in Germany is appended to the report. The bibliography is 

 arranged alphabetically according to authors and chronologically under each author. 



Tlu' information contained in the report is from German sources and largely from 

 official reports. It appears from the official German reports that microscopic inspec- 

 tion of pork as carried out in Germany is not successful in detecting all the cases of 

 trichinosis in hogs, and in fact a considerable portion of cases of trichinosis in man are 

 traced directly to pork which had been inspected by German inspectors and passed 

 as free from trichinte. The evidence for trichinosis in man from eating pork of 

 American origin is considered inconclusive. 



The utilization of meat condemned on account of trichina, Edelmann {Deut. 

 Tliierdrztl. Wchnschr., 9 {1001), No. 18, pp. 181, 16";?).— While the complete destruc- 

 tion of such meat or its use for technical purposes satisfies ail sanitary requirements 

 in the matter, the author oelieves that the meat may safely be given to inspectors 

 or other persons who understand the danger of it when not sufficiently cooked. 



Studies on Echinococcus alveolaris or multilocularis, N. Melnikow- 

 Raswedexkow {Bcilr. I'alli. Anol. n. All//. I'dlli., 1901, .s«y^. ^, ]>p. 295, ph. G, fix/x. 94). — 

 The general results of this investigation may be briefly stated as follows: The alveolar 

 echinococcus is found in animals and man primarily not in the liver but in other 

 organs such as the brain, spleen, and sujjrarenal bodies. The changes which are 

 induced in the tissues of the liost through this parasitism depend upon the peculiar- 

 ities of the parasite itself. The unilocular or multilocular hydytids are different 

 species of parasite and do not represent the encysted stage of the same s])ecies. This 

 parasite naa a much wider distribution in Russia than has previously been suspected.
