Studies on the relationships between serum bactericidal activity and uncomplicated genital infections due to Neisseria gonorrhoeae. 1978

G F Brooks, and I Ingwer

This report concerns the relationships between patients' uncomplicated genital infections due to Neisseria gonorrhoeae and the bactericidal activity of their sera against their infecting organisms. Forty isolates of N. gonorrhoeae and 91 serum samples were obtained from 23 patients with their first or repeated gonococcal infections. Of 32 sera obtained at the time of infection, 14 (44%) were bactericidal for the infecting strains. Of convalescent-phase sera from 27 infections, 12 (44%) were bactericidal; 22%-33% of convalescent-phase sera had increased bactericidal activity when compared with acute-phase sera or sera obtained before infection. Eleven patients developed 17 new infections after sera and negative cultures were obtained; in six (35%) the previously obtained sera were bactericidal but did not prevent infection.

UI	MeSH Term	Description	Entries
D009344	Neisseria gonorrhoeae	A species of gram-negative, aerobic bacteria primarily found in purulent venereal discharges. It is the causative agent of GONORRHEA.

D001770	Blood Bactericidal Activity	The natural bactericidal property of BLOOD due to normally occurring antibacterial substances such as beta lysin, leukin, etc. This activity needs to be distinguished from the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy, which is measured by a SERUM BACTERICIDAL TEST.
