“…Effective control programs have been instituted in several metropolitan areas in the United States and Canada (1,13), as well as in several western European countries (19,32), which have resulted in dramatic declines in the prevalence of both C. trachomatis and N. gonorrhoeae in targeted populations.…”

Multicenter Evaluation of the BDProbeTec ET System for Detection of Chlamydia trachomatis and Neisseria gonorrhoeae in Urine Specimens, Female Endocervical Swabs, and Male Urethral Swabs

The performance of the Becton Dickinson BDProbe Tec ET System Chlamydia trachomatis and Neisseria gonorrhoeae Amplified DNA Assays (BD Biosciences, Sparks, Md.) was evaluated in a multicenter study. Specimens were collected from 2,109 men and women, with or without symptoms, attending sexually transmitted disease, family planning, and obstetrics and gynecology clinics. Both swab and urine samples were collected, and the results obtained from 4,131 specimens were compared to those from culture and the LCx nucleic acid amplification test (Abbott Industries, Abbott Park, Ill.). PCR and cytospin of the culture transport medium with chlamydia direct fluorescent antibody staining were used to adjudicate chlamydia culture-negative results. Sensitivity and specificity were calculated both with and without use of the amplification control (AC), with little apparent difference in the results. Without the AC result, sensitivity for C. trachomatis and N. gonorrhoeae were 92.8 and 96.6%, respectively, for cervical swabs and 80.5 and 84.9% for urine from women. C. trachomatis and N. gonorrhoeae sensitivities were 92.5 and 98.5%, respectively, for male urethral swabs and 93.1 and 97.9% for urine from men. This amplified DNA system for simultaneous detection of chlamydial and gonococcal infections demonstrated superior sensitivity compared to chlamydia culture and has performance characteristics comparable to those of other commercially available nucleic acid-based assays for these organisms.

“…It is also necessary to remain vigilant in continuing the surveillances even if a low incidence is monitored. For instance the low burden of sexually transmitted infections during the 90’s [ 21 ] was tempting to remove them from the list. Those years the decrease in incidence was a profit from the massive prevention campaigns for HIV/AIDS.…”

Surveillance of Infectious Diseases by the Sentinel Laboratory Network in Belgium: 30 Years of Continuous Improvement

et al. 2016

In 1983 the sentinel laboratory network was established because of the need to describe the epidemiological evolution of infectious diseases. During the study period of 30 years (1983–2013), microbiology laboratories reported on weekly basis the laboratory diagnosed cases for a selection of infectious diseases. This resulted in a large longitudinal laboratory based database allowing to provide trends over time and distribution by person and place. During this period, adaptations to data collection were made due to changes in diagnostic methods and public health priorities, introduction and application of digital revolution, and multiple reorganizations of the laboratories. Since the surveillance network is dynamic, it necessitates a continuous evaluation to ensure that, over time, it continues to be representative of the general epidemiological trends in the country. Secondly the aim is to examine the robustness and stability of this surveillance system. Here we demonstrated that the flexibility of the data collection methodology by the sentinel laboratory network is unique and that adaptations do not affect the capacity of the system to follow trends. Therefore, the surveillance by this network is representative of the current epidemiological situation in Belgium. To our knowledge, no such surveillance network with such a long-term follow-up and demonstrated stability for multiple infectious diseases in the general population was earlier described. Furthermore, expected trends due to the implementation of vaccination or other events were accurately detected. The collected data obtained from this network allows interesting comparisons with other national and international information sources.

545 male patients with a tentative diagnosis "urethritis" were examined between November 1984 and December 1994 in the Department of Dermatology and Venerology of the Military Hospital in Ulm. The patients, aged from 18 to 58 years (mean age 24.1 years), were examined according to a standardized diagnostic procedure: Smear preparations from the urethra with subsequent gram staining, bacterial cultures for aerobic bacteria, Neisseria gonorrhoeae (cultures and Phadebact gonococcus test), mycoplasma cultures (Mycoplasma hominis (M. hom.); Ureaplasma urealyticum (U. u), and Chlamydia trachomatis using several methods, primarily DIFT (Syva Micro-Trak). Trichomonas vaginalis counts in urine sediment 441 patients (81%) had 4 or more leukocytes per high-power (x1000) field in the gram stained specimens. In these 441 urethritis-patients the following germs could be detected: Trichomonas vagin 3 (1%), N. gonorrhoeae 80 (18%), Mycoplasma 94 (21%) [U. u. 59, M. hom. 24, both 11], C. trachomatis 114 (26%), other pathogenic bacteria 135 (31%). In 114 patients (26%) no bacteria could be identified. A single infection was diagnosed in a total of 242 patients (55%), a double infection was determined in 71 patients (16%) while a triple infection was found in 14 patients (3%). The spectrum determined in the single infection included the following: N. gonorrhoeae 41 (9%), Mycoplasma 45 (10%), C. trachomatis 67 (15%), other pathogenic bacteria 89 (20%) (most frequently found germs were Enterococcus, beta-hemolytic Streptococcus, Escherichia coli, Staph. aureus). In the double infections combinations with aerobic bacteria dominated. In triple infections, mycoplasma were most common. During the investigation period the number of patients with urethritis symptoms declined at a constant rate.
