Studies on Streptococcal Fibrinolysis

Studies of streptococcal fibrinolysis; the inhibition of streptococcal fibrinolysis by antifibrinolysin and antiprotease.

Studies on Streptococcal Bacteriophages

Evidence has been presented that the burst size in the Group A and Group C streptococcal phage-host systems are in general similar producing approximately 13 phage particles per infected coccus. The exception was the C1 phage which produced 10 times more virus particles than all the other phages tested. The eclipse period for the A25 phage-host system was found to extend for 34 min, while the C...

Studies of streptococcal fibrinolysis; a quantitative method for the estimation of serum antifibrinolysin.

Streptococcal Fibrinolysis: a Proteolytic Reaction Due to a Serum Enzyme Activated by Streptococcal Fibrinolysin

1. Methods for the preparation and partial purification of streptococcal fibrinolysin are described. 2. The lysis of fibrin clots in the presence of streptococcal fibrinolysin is associated with proteolysis of the fibrin. Digestion is due to an enzyme normally present in serum or plasma in an inactive state, which is activated by fibrinolysin. Fibrinolysin alone has no demonstrable proteolytic ...

Studies on the Conjugation of Streptococcal Nucleoprotein*

Recent observations on conjugated proteins (l-6) raise the question as to whether the prevailing ideas concerning the nature of the attachment of nucleic acids with the proteins are valid. With certain exceptions it has generally been assumed that the nucleoproteins are salts of a polyvalent nucleic acid and a polyvalent base (protein) (7). The ideas that nucleoproteins are salt-like (polar), o...
