As reference system was used a polyvalent Ps. aeruginosa antigen and a corresponding rabbit antiserum. Fifty-one (93 per cent) of the 55 Ps. aeruginosa antigens in the reference system were present in all the strains and corresponding antibodies in the reference system could be completely absorbed by all the strains. Complete cross-reactivity was also found between antigens of the reference system and 3 of the 4 antigens present only in some of the strains. The last of the 4 antigens not present in all the strains could only absorb part of the corresponding antibodies in the reference system. Absorption experiments with whole heat-killed bacteria indicate that this antigen is related to the O group antigens of Ps. aeruginosa. None of the antigens of the reference system were related to the mucoid substance produced by some strains of this bacterium.","PeriodicalId":75410,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

In contrast to the avirulent parasites, attenuated organisms did not appear to form cysts in mice and rabbits, although parasites could be isolated from such animals as long as three months after their inoculation. Rabbits infected with parasites of attenuated - virulence had high antibody levels, and survived challenge with virulent Toxoplasma gondii. Cysts were not detected in the brains of such rabbits following this second infection. By following the generation of Toxoplasma gondii in mouse peritoneal cavities, it was found that attenuated parasites resembled avirulent more than virulent organisms. Although the effect of attenuation was mainly on the parental generation of parasites, some genetic effect seemed to be involved as well.","PeriodicalId":75410,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

The minimum dose in 3- to 4-week-old mice was found to be as small as 10(2) to 10(3) p.f.u. in 0.1 ml of diluent. Suckling rats and hamsters, aged up to 7 and 14 days, respectively, were found to be convenient as alternative test animals.

Conditions were chosen to minimize the influence on sorption of bacterial polymer production, passive sorption being studied rather than attachment mediated by metabolic activities. Sorption of S. faecium increased with increasing temperature (to 50 degrees C), time, and cell concentration, but equilibrium apparently was not reached even after incubation for 8 hours or at a cell concentration of 3 X 10(10) per ml. Sorption increased with solute molarity up to 0.1 M concentration of NaCl and KCl, indicating an effect of the electrical double layers on the apposition of cells to the glass surface. Desorption of bacteria could be obtained after multiple washings of the glasses in buffer or by the action of Tween 80, but not if sorbed bacteria were left in distilled water, various salt solutions, urea, or in suspensions of unlabelled bacteria. It was concluded that sorption occurred as a result of chemical interactions between the glass and the cell surface. Tween 80 at a concentration of 1 per cent inhibited sorption to 26 per cent of buffer controls, 2 M urea was less effective, and 1 M NaCl was without effect. It is suggested that hydrophobic interactions may be of importance in the binding of S. faecium to glass.","PeriodicalId":75410,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.
