Taxon \"minor group\" and Taxon C on their amino acid and carbohydrate metabolism by thin layer chromatography. The 17 reference strains studied showed almost identical results within the different species and taxa in both, amino acid and carbohydrate metabolism patterns. Based on a few differing enzymatic reactions a reduced species- and taxon-specific reaction pattern could be established, which included L-alanine, L-citrulline and L-threonine of the amino acids as well as D-ribose, alpha-D-xylose, mannitol, trehalose, beta-melibiose and alpha-lactose of the carbohydrates. This differentiation system allowed a reliable identification of 7 field strains whereas 4 additional ones, hitherto pre-classified as H. parasuis, could not be associated with any of the above species and taxa.</p>","PeriodicalId":23821,"journal":{"name":"Zentralblatt fur Bakteriologie, Mikrobiologie, und Hygiene.

Remarkable differences among the hly genes tested were found in their haemolytic activity and in the regulation of the haemolytic activity by the extracellular iron concentration. Under iron-limiting growth conditions the haemolysin secretion encoded by 6 hly plasmids, but not by the remaining 14 hly plasmids and the chromosomal hly genes, was significantly induced. The 6 plasmids all derived from human isolates, belonged to the incompatibility groups FIV and FVI and showed similar restriction patterns. Two hly determinants, encoding an inducible haemolysin secretion, cloned from plasmids isolated in Berne and Paris, respectively, showed identical restriction maps, indicating a common origin.

Attempts to reactivate an abortive infection possibly established in lymph node or spleen cells by stimulation with phytohemagglutinin or lipopolysaccharide rendered no positive results, not even when adult (i.e. at least 6-week old), but immunodeficient mice were used as test animals. On the other hand, isolation of infectious virus from lymph node and--at a lesser rate--from spleen cells was successful in immature 4 to 6-week old mice, particularly when these had undergone pretreatment with cyclophosphamide, silica, antimacrophage serum and/or cortisone; 5 days post infectionem being the date of optimum virus yield. HSV-1 infected mice were more frequently positive than those with HSV-2, and genetically sensitive animals more so than resistant mice. The data indicate that the lymphohaematogenous spread of the virus is inhibited by means of an active defence mechanism, and that unspecific defence factors on the cellular level, probably macrophages and NK-cells, are essentially responsible. This reveals that the lethal generalized infection is prevented and the neural spread can gain its essential role in the pathogenesis of the HSV-infection.</p>","PeriodicalId":23821,"journal":{"name":"Zentralblatt fur Bakteriologie, Mikrobiologie, und Hygiene.

Q fever associated with abortion was first demonstrated in 1983 during laboratory diagnostic examination of fetuses and placentae. From case history data and on-the-spot investigations it is clear that in cattle stocks abortion caused by C. burnetii occurs sporadically, whereas in sheep flocks numerous abortions may take place within a short time. Losses caused by Q fever on the affected large-scale farms amount to 5-15%, which arise partly from reduced calf or lamb crop and partly from the death of offspring born with poor viability and being highly susceptible to neonatal disease. Altogether 87 cases of human disease caused by C. burnetii have been reported in the Hungarian literature.
