For this present publication as a survey the total material covering 34,935 strains was analyzed and interpreted. Besides a short introduction describing the general examination procedure for streptococci and the encoding of results for the data bank the material is condensed in different tables considering the incidence of pathogenic species occuring mainly in man and animals. In addition findings of enterococci and lactic streptococci are presented. 41.8% of the strains examined were isolated from human specimens, 46.7% from cattle and the remaining ones from pigs, horses, dogs, laboratory animals and others. Only 2.0% of all cultures could not be identified as one of the known species. Remarkable observations are - the high incidence of group B-Streptococci in man - the unexpected frequency of typical \"human\" streptococci as those of group F and G and also Sc. milleri and Sc. MG in different animals - the possible interrelation of group L- and P-streptococci in pigs and cattle - the overlap of Sc. faecalis and Sc. faecium in man and animals showing no typical distribution as it is postulated in the literature - the high percentage of unidentifiable streptococci from pigs and laboratory animals as an eventual indication for some new species. In consecuting papers some problems emerging from the presented material and own experiments will be discussed as - interrelation of group B-Streptococci in man and cattle - incidence and importance of enterococci in humans, animals and foodstuffs and - classification of species not to identify by serological grouping.</p>","PeriodicalId":23838,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

Use was made of Tryptic Soy broth (TSB)-grown O-cells that had been boiled for 1 hour; 0.145 M NaCl proved a satisfactory diluent. Various technical parameters of this test were examined as well. Rabbit anti-O immune sera, that had been elicited with 5 x concentrated, TSB-grown, 1 hour-boiled O-cells of all 15 currently employed O-antigen reference strains of S. marcescens yielded satisfactory O-agglutinin titers. The tube O-agglutination test compared favorably with the indirect hemagglutination technic, although the latter technic yielded significantly higher O-agglutinin titers with merely 7 of the 15 O-antigens of S. marcescens. The tube O-agglutination test permitted detection of higher O-agglutinin titers than a microtiter O-agglutination test utilizing O-cells that had been stained with safranin O. Conversely, titers obtained with TTC-stained O-cells in a microtiter agglutination procedure approximated those yielded by the tube O-agglutination test, but O-cells of the various S. marcescens strains were stained nonuniformly by triphenyltetrazolium chloride (TTC). As before, there existed marked serologic cross-reactivity between O-antigens O6 and O14. A new O6 candidate strain, S. marcescens isolate S 1i, serotype O6:H20, was proposed. Contrary to O-agglutinins of human control serum, the O-agglutinins of rabbit anti-O immune sera proved refractory to treatment with 0.1 M of 2-mercaptoethanol (2-ME) and 0.01 M dithiothreitol (DTT) respectively. Dual absorptions of rabbit anti-O immune sera with killed cells of Staphylococcus aureus Cowan I (protein A), failed to significantly reduce O-agglutinin titers, although human IgG and IgM was bound by protein A. It was tentatively concluded that the 2-ME- and DTT-refractory rabbit anti-S. marcescens O-agglutinins resided in the IgM immunoglobulin class.</p>","PeriodicalId":23838,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

The virus is replicated in the cells of the lymphomycoid complex, whereby the production of a chymotrypsin is induced. In swine fever the lymphatic glands and the lymph flow are increased. Fifteen normal pigs had chymotrypsin contents in the lymph of the body lymphnodes of 0,4 U/l, nine pigs suffering hog cholera 1,5 U/l. In the intestinal lymphnodes the chymotrypsin concentration was normally 2,9 U/l and in swine fever 3,5 U/l. Chymotrypsin which is present may induce the production of further chymotrypsin. Fourteen pigs suffering from swine fever showed increased peritoneal fluids (50 to 120 ml), whereby chymotrypsin was found in 5 cases. The lymphflow was assumed to be five times higher, when compared to control animals. This entails a seven-fold increase of chymotrypsin which enters the blood stream. In some cases the virus titers are higher in the lymph specimen and peritoneal fluids than in the serum. Increase of chymotrypsin concentration reduces the resistance of the virus in the lymph. Obviously the virus is spread in the body migrating with the lymph flow. However, the increasing chymotrypsin concentration seems to inactivate the virus and lymph retains its defense character. Detection of the fluorescent antigen is correlated with the evidence of the proteolytic precipitating antigen. After infection with the virus of swine vesicular disease increase of chymotrypsin is also evidenced in the lymph but to a lower degree. Therefore in swine fever the lymphnodes cause chymotrypsin formation to an extent which may explain the pathophysiological disorders in those physiological systems, that are controled by serine proteases.</p>","PeriodicalId":23838,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

Experimental conditions included a nine-fold vaccination schedule with collection of serum and nasal fluid. The parameters studied were determination of serium and local antibody formation as well as the demonstration of specific IgE antibodies in serum and nasal fluid. Our major interest was directed towards the question of potential sensitization after repeated doses of non-purified oral vaccine. The close medical follow-up of the subjects revealed no clinical signs of atopic reaction. There were no complaints regarding adverse reactions usually following local application of live influenza vaccines. Determination of total serum IgE rederately elevated levels before, during und after the trial; one vaccinated subject showed high concentrations prior to vaccination with no significant change during the experiment. That individual was ultimately classified atopic with a pronounced hypersensitivity to egg protein. Nevertheless this person tolerated nine doses of vaccine without side reactions and showed no significant increase in total or specific IgE antibodies. Concentrations of IgE in nasal secretion of non-atopic subjects are less than 2U/ml, whereas they are frequently higher in allergic patients and in the presence of nasal IgE levels greater than 4 U/ml one would expect a specific reaction to challenge allergens. In our vaccinees nasal IgE values were consistently within normal range, at no time exceeding 2.6 U/ml, even the atopic subject did not exhibit higher levels in nasal fluid. A correlation between systemic and local IgE antibodies revealed no pathognostic relations; in addition to this, specific IgE-serum-antibodies as measured in the RAST against ovalbumin allergen did not show any correlation to vaccination. These data present good evidence for the innocuity of the vaccine with regard to its repeated application in man.</p>","PeriodicalId":23838,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.
