[Serum antibody determination in patients with urinary tract infections during pregnancy]

In 37 patients with significant bacteriuria in pregnancy antibody-determinations were carried out by means of bacterioagglutination and indirect hemagglutination. High antibody titres in serum could be detected in 13 patients with clinically acute pyelonephritis. Bacteriurias in connection with chronical pyelonephritis resulted in titres above normal values in few cases only. In no case there was a connection between asymptomatic bacteriurias and an increasing antibody titre.
