Thus, I am standing here, in a way, as an ambassador of the German medicine and veterinary medicine and, in particular, of food hygiene which has been developed on the basis of it, and I would like to refer to the traditional friendship between our countries and to give, at the same time, new impulses to the collaboration in our field. In this connection, I remember with pleasure one of my predecessors in this function, Prof. Dr. and Dr. h.c. J. Fortner, who maintained close connections in particular to the Animal Health Institute and who showed to me with pride his appointment by you as an Honorary Member back in the sixties. As the present President of the German Federal Health Office, which is located in Berlin, I wish to remind you of Robert Koch and his disciple Kitasato, two internationally highly estimated specialists in the field of infectious diseases, who established the traditional collaboration in the field of the control of infectious diseases in 1885-1892. In July of this year we will celebrate the centenary of the Robert Koch Institute of this Office in the presence of representatives of the famous Kitasato Institute. Finally, I would like to inform you that I am one of the sponsors of the Japanese-German Centre which was established in the presence of the former Japanese Prime Minister, Mr. Nakasone, in Berlin in 1986. At present I am chairman of the working group \"Medicine and Biotechnology\" of that Centre. I hope that my stay in your country will also be beneficial for the collaboration with the Japanese veterinary medicine under the roof of this Centre in Berlin. You may imagine that the German population and the people of Berlin are happy about the reunification and the","PeriodicalId":414713,"journal":{"name":"Bifidobacteria and Microflora","volume":"20 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125775209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Members of the Bacteroidaceae colonize both the upper and lower regions of this system but several factors contribute to limit specific taxa to certain niches . In Bergey's manual of systematic bacteriology (2) , 3 genera, Bacteroides, Fuso-b acterium and Leptotrichia are recognized on the basis of physiological tests and acid end product analysis. The genus Leptotrichia remains monospecific , with L. buccalis,( which produces lactic acid as a major end product of metabolism) as its only species. Members of the genus Fusobacterium are characterized by the production of butyric acid and their general asaccharolytic nature . Though the genus appears to be homogeneous, considerable intrageneric heterogeneity exists. Whereas most species have DNA base compositions within the range 25-34 M % G+ C, some such as F. sulci (39%) and the type strain of F . naviforme (43%) are clearly atypical . Some species such as F. nucleatum (type species) and F. periodonticum possess a peptidoglycan structure based upon meso-lanthionine (AIo) while others such as F. varium contain a dl-diaminopimelic acid structure (7, 11, 22) . F. mortiferum atypically has a mixture of both diamino acids. The nature of cross-linkage of these peptidoglycan chemotypes is shown in Fig. 1. Recently we have shown that glutamate is both a useful diagnostic marker at the species and generic levels (4, 6, 20) and is utilized as a major source of energy (5, 10) . Three pathways, viz the 2-oxoglutarate , mesaconate and 4-aminobutyrate, were reported for the catabolism of glutamate (3) . The relationship between these pathways of glutamate catabolism and the distribution of peptidoglycan chemotypes is shown in Fig . 2. Thus despite the apparent homogeneity of the genus, it is in need of urgent chemotaxonomic analyses. The type species was recently shown to be heterogeneous by both DNA-DNA hybridization , enzyme electrophoretic patterns and ribosomal RNA gene restriction patterns","PeriodicalId":414713,"journal":{"name":"Bifidobacteria and Microflora","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121583006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is well known that piglets less than four weeks old are immunodeficient (1, 4, 14, 31, 35). The poor immunoresponse of the intestinal mucosa of piglets in this period is responsible for various local infections especially colibacillosis and viral diarrhea despite the presence of a large amount of immunoglobulin (Ig) in colostrum. This immunodeficiency of neonatal piglets seems to be analogous to the human babies' common variable hypogammaglobulinemia with B lymphocyte (10, 16). Though neonatal piglets are immunologically competent and respond to various antigenic stimulation, such as sheep blood cells and actinophage, the uncommitted multipotent immunocompetent cells are dominant (14). Since at this stage, monopotent (monoclonal) immunocompetent cells and memory cells are unable to develop, nor are the plasma cells able to mature, the secondary immune response and the producing ability of Ig are poor (3, 15). In newborn animals, there are very few plasma, cells in the lamina propria of the small intestines, and lymphoid follicles are poorly defined. These findings have also been proved by histological observation (9). In this context, the investigation has been carried out as follows; (1) analysis of immunoresponses in piglets of suckling stage, (2) serum concentration and properties of afetoprotein and serum level of albumin, and (3) influence of immunopotentiator on suckling piglets from the viewpoint of immunoresponse.","PeriodicalId":414713,"journal":{"name":"Bifidobacteria and Microflora","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132312772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
