Hemolytic Activity of a Togavirus, Getah* [PDF]

open access: yesMicrobiology and Immunology, 1979
AbstractA purified toga‐alphavirus, Getah (GET), showed optimal hemolytic activity for one‐day‐old chick red blood cells when incubated at 37 C for 120 min at pH 6.2. Experimental data obtained from various angles, such as pH dependency, inhibition by virus‐specific antiserum and by concanavalin A, indicated that the hemolysis was a property of the ...

THE FIBRINOLYTIC ACTIVITY OF HEMOLYTIC STREPTOCOCCI [PDF]

open access: yesJournal of Experimental Medicine, 1933
Broth cultures of hemolytic streptococci derived from patients are capable of rapidly liquefying normal human fibrin clot. The active fibrinolytic principle is also contained in sterile, cell-free filtrates of broth cultures. The degree of activity of filtrates parallels the activity of whole broth cultures sufficiently closely to ...
