Culture diagnosis of gonorrhoea--a comparison between two standard laboratory methods and a commercial gonococcal culture kit (Kvadricult).

The efficiency of a commercial kit--Kvadricult--intended for the culture diagnosis of gonorrhoea and specially designed to simplify "bedside" inoculation, was compared in two laboratories with their standard laboratory gonococcal (GC) culture methods. The yields of specimens inoculated "bedside" were compared with those inoculated after transport for 4-18 hrs in a modified Stuart transport medium. The highest positive yield was obtained by "bedside" inoculation with approximately equal results for the conventional methods and the Kvadricult system. Compared with "bedside" inoculation, the loss of positive specimens after transport was less than 10% in one laboratory but more than 17% in the other, which was found to be due to inferiority of the GC medium used in this laboratory, the reasons for which are discussed. Prolonged transportation of specimens for 2 days increased the loss of positive specimens, rising to as much as 55% even at the laboratory with the more efficient GC medium. These losses can obviously be avoided by transport for less than 24 hours--or better still, by "bedside" inoculation. From this point of view we have found the Kvadricult system efficient and easy to handle.

Neisseria meningitidis in specimens from urogenital sites. Is increased awareness necessary?

Neisseria meningitidis serogroups B type 2 and Y were isolated from urogenital specimens from three heterosexual patients. The first patient was a young man with the clinical signs and microscopic findings of a typical gonococcal urethritis. The second was a middle-aged woman with cervicitis, in whom neither Neisseria gonorrhoeae nor Chlamydia trachomatis were demonstrated by culture. In the third patient, a young woman, N. meningitidis was associated with cervicitis, acute salpingitis, and peritonitis. The patients' clinical symptoms responded quickly to antibiotic treatment. Meningococci of the same serogroup/serotype as the index cases were demonstrated in two of the sexual consorts in pharyngeal specimens but not in genitourinary specimens. Orogenital sexual practice seemed to be the most likely route of transmission. During the period of this study (August 1989-March 1990), the three meningococcal strains observed at the authors' laboratory represented 20% of the total number of urogenital isolates of pathogenic Neisseria. A greater awareness of this problem from medical, diagnostic, epidemiologic, and legal viewpoints is therefore needed.

Gonorrhea, genital chlamydial infection, and nonspecific urethritis in male partners of women hospitalized and treated for acute pelvic inflammatory disease.

BACKGROUND AND OBJECTIVES: Acute pelvic inflammatory disease (PID) is often a complication to a sexually transmitted disease (STD), the most important agents being Neisseria gonorrhoeae and Chlamydia trachomatis. However, very little is known of the genitourinary status of the male partners of women with acute pelvic inflammatory disease (PID). GOAL OF THIS STUDY: To determine the presence of N. gonorrhoeae and/or C. trachomatis infection or nonspecific urethritis (NSU) in regular sexual male partners of women with acute PID. STUDY DESIGN: Two hundred regular sexual male partners to 196 women admitted to a hospital for treatment of acute PID were referred by contact tracing to the sexually transmitted disease outpatient clinic for clinical and laboratory examination regarding N. gonorrhoeae and/or C. trachomatis infection, or NSU defined as the presence of > 5 polymorphonuclear leukocytes per high-power field (x1,000) in > 4 fields and with negative laboratory tests for N. gonorrhoeae and C. trachomatis. RESULTS: The majority of the males was in the age group 20 to 29 years of age, female sexual partners in 15 to 24 years years of age. N. gonorrhoeae was demonstrated in 42.9% of the male partners to women with acute PID and concomitant gonorrhea. The corresponding figure for C. trachomatis was 43.7%. Nonspecific urethritis was diagnosed in 26 (33.8%) of the male partners to 77 women were diagnosed with N. gonorrhoeae and/or C. trachomatis infection, and in 45 (37.8%) partners of 119 women without such an infection. In all, N. gonorrhoeae, C. trachomatis or NSU were demonstrated in 117 (59.7%) of the 196 male partners, but only 32% of the males with N. gonorrhoeae or C. trachomatis and 8.5% of those with NSU presented subjective symptoms of urethritis. CONCLUSION: The findings of the study stress the need for routine clinical and laboratory examination and treatment of sexual male partners to women with acute PID.
