desoxyribonuclease/fever

Rabbit antisera against partially purified streptococcal desoxyribonuclease inhibit the action of the enzyme on its substrate. The activity of pancreatic desoxyribonuclease is not affected by these antisera. Similarly antibody against pancreatic nuclease does not inhibit the streptococcal enzyme.

For the serological diagnostics of the diseases caused by Streptococcus pyogenes (A-streptococci) and secondary diseases (rheumatic fever, acute glomerulonephritis) in the first place the anti-streptolysin reaction is at disposal. In the judgment age is to be taken into consideration and the

Studies on the purification of group A streptococcal extracellular antigens detectable with naturally occurring human antibodies from normal individuals have been extended. It has been shown that streptococcal electrophoretic fractions intermediate between the most rapidly migrating components are

In 1972 more than 20% of boys admitted to a closed community (Junior Detention Centre) developed acute tonsillitis and group-A streptococci were isolated from more than 40% of all boys at some time during their stay of two months. The most common serotype was M-type 5, which has frequently been

It has been shown by agar precipitin tests (Ouchterlony and Oakley) that human sera may contain from 0 to 5 antibodies against antigens present in a partially purified streptolysin O preparation, and from 0 to 7 antibodies against antigens in a crude ammonium sulfate concentrate of the streptococcal
