Background: Sexually transmissible infections (STIs) remain highly prevalent, and HIV is increasing, among female sex workers (FSWs) in Indonesia. Our aim was to determine the prevalence of, and risk factors for, STIs among FSWs in Manado, Indonesia. Methods: We recruited FSWs mainly at their workplace: they completed a questionnaire and provided a urine sample and self-collected vaginal swab. Samples were tested using multiplex polymerase chain reaction, followed by reverse line blot hybridisation. Results: We recruited 221 FSWs, (median age: 25 years). During the previous 3 months, 30% reported never using condoms; only 2.7% always used condoms. Of 217 women with urine samples, 49% had a ‘curable STI’: 10.6% with gonorrhoea, 26.7% with chlamydia, 12.4% with Mycoplasma genitalium and 22.6% with trichomoniasis. Independent risk factors for gonorrhoea were: domiciled outside North Sulawesi (P = 0.001) and age 16–25 years (P = 0.02); for chlamydia: no prior history of STI symptoms (P = 0.003) and age 16–25 years (P = 0.02); for Mycoplasma genitalium: number of clients on last day of sex work (P = 0.004); for trichomoniasis: number of clients per week (P = 0.04). When these four infections were grouped as any ‘curable STI’, independent associations were: number of clients on the last day of sex work (P = 0.001), age 16–25 years (P = 0.02) and sex working for fewer than 2 years (P = 0.03). Conclusions: This is the first report of M. genitalium infection in Indonesia. The high prevalence of STIs and low condom use among these FSWs suggest their vulnerability to the HIV epidemic in Indonesia. They need enhanced interventions, including outreach screening, and periodic presumptive treatment.

The 16S Rrna Gene

Mycoplasma genitalium is one of the smallest self-replicating organisms. It is an obligate parasite found in the human genital tract. In men, the bacteria cause both acute and chronic non-gonococcal urethritis (NGU). In women, it has been associated with pelvic inflammatory disease and cervicitis among other related infections. Treatment of M. genitalium related infections has been effective using antibiotics such as the macrolides (e.g. azithromycin) and fluoroquinolones. However, there have been recorded cases of resistance to these antibiotics in various parts of the world as a result of a mutation in the 23SrRNA gene, although the antibiotic resistance has not been well established. The aim of this study was to detect M. genitalium in 352 swab samples collected from a clinic for sex workers in Nairobi, Kenya. DNA was extracted from the swabs and stored as a crude extract at -31°C. The swab lysates were subjected to direct polymerase chain reaction using primers that specifically target the 16S rRNA gene for M. genitalium. A total of 29 samples tested positive for M. genitalium. The data results showed a M. genitalium prevalence of 8.24% among sex workers in Nairobi, Kenya.

Infection Bactérienne

Les pneumonies acquises à l’hôpital (PAH) sont fréquentes. À l’ère des techniques diagnostiques de biologie moléculaire (multiplex polymerase chain reaction), les rares données disponibles estiment que les virus respiratoires sont impliqués dans 22 à 32 % des épisodes. Les patients immunodéprimés constituent probablement la population la plus à risque. La présentation clinique et radiologique ne diffère pas entre pneumonies bactériennes, virales et mixtes (virus–bactérie). L’excrétion prolongée de virus respiratoires dans les voies aériennes a été rapportée chez les patients immunodéprimés. Elle pourrait promouvoir la co-infection bactérienne, associée à des durées d’hospitalisation prolongées. L’acquisition intrahospitalière a été démontrée chez tous les virus respiratoires. Elle encourage la mise en œuvre et le respect des mesures d’hygiène et de confinement, dans l’objectif de protéger soignants, visiteurs et patients. De nombreux points restent largement méconnus, relatifs aux interactions entre virus respiratoires et pathogènes non viraux, aux périodes d’incubation, ou encore aux durées d’excrétion virale. L’amélioration des techniques diagnostiques et l’accumulation de données épidémiologiques et cliniques devraient permettre de mieux appréhender le rôle des virus respiratoires dans les PAH. Cette meilleure connaissance aidera à rationaliser l’utilisation des tests de détection et facilitera l’interprétation de leurs résultats. Elle guidera aussi le clinicien dans l’utilisation future des nombreuses molécules antivirales actuellement en développement clinique chez l’homme.

Introduction: The aim of the current study was to investigate the prevalence of virulence genes in uropathogenic Escherichia coli (UPEC) isolates in Ilam. Materials and Methods: For this purpose, a total of 80 UPEC isolates were collected for patients with UTIs during a 6 months period. The multiplex polymerase chain reaction (multiplex PCR) was used to detect the papEF, fimH, iucD, hlyA, fyuA, and ompT genes. Results: The prevalence of fimH, papEF, iucD, fyuA, hlyA, hlyA, and ompT genes were 87.5%, 47.5%, 60%, 67.5%, 27.5%, 47.5% and 71.2%, respectively. Among all of the isolates, 27 profiles were obtained. Conclusion: Our findings demonstrated that the most prevalence was found for fimH, and different distribution of virulence genes suggested different ability of pathogenicity.
