[Nuclease-antibodies in infections with Serratia marcescens (author's transl)].

A total of 467 presumable healthy men of age eighteen yielded titres of anti-serratia-nuclease that ranged from 1:4 to 1:6. One third of 56 patients, who had been infected with Serratia marcescens (urinary-, wound-, respiratory-infections, and bacteremia) yielded raised anti-nuclease titres, which amounted maximaly 1:16. The diagnostic utility of this serological test was discussed.
