    Summary
    This summary is machine-generated.

    The pharynx is a significant reservoir for Neisseria gonorrhoeae (gonorrhea), including penicillinase-producing strains (PPNG). Oral-to-genital transmission highlights the importance of pharyngeal screening for gonorrhea control.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Public Health

    Background:

    • Neisseria gonorrhoeae (gonorrhea) infections pose a significant public health challenge.
    • Penicillinase-producing Neisseria gonorrhoeae (PPNG) strains present treatment difficulties.
    • The role of the pharynx as a reservoir for N. gonorrhoeae requires further investigation.

    Purpose of the Study:

    • To determine the prevalence of N. gonorrhoeae in pharyngeal and genital cultures.
    • To assess the proportion of penicillinase-producing N. gonorrhoeae (PPNG) strains.
    • To evaluate the significance of the pharynx as a source of gonococcal infections and its role in transmission.

    Main Methods:

    • Cultures of genital sites and pharynx were collected from 903 prostitutes and 102 active-duty men.

  • Pharyngeal and genital cultures were analyzed for Neisseria gonorrhoeae, including PPNG.
  • Retrospective review of male gonococcal urethritis cases to identify potential oral-to-genital transmission.

    • Main Results:

    • Positive pharyngeal cultures were observed in 2.2% of women and 6% of men.
    • Both penicillin-sensitive and PPNG strains were recovered.
    • A retrospective review identified 46 cases of probable oral-to-genital transfer of N. gonorrhoeae among over 2,600 cases of urethritis, with 15 of these being PPNG.

    Conclusions:

    • The pharynx serves as an important reservoir for Neisseria gonorrhoeae, including drug-resistant PPNG strains.
    • Oral-to-genital transmission is a notable route for gonorrhea spread.
    • Pharyngeal screening should be considered for comprehensive gonorrhea control strategies.
