Abstract
Mycoplasma genitalium (MG) and Trichomonas vaginalis (TV) can lead to long-term sequelae in males and females; however, global prevalence data vary between geographical regions, as these sexually transmitted infections are not included in routine screening. The objective of this study was to use the cobas® TV/MG assay to assess the point prevalence of TV and MG in specimens from men and women over a broad European geographical area. Urine, vaginal, endocervical, and rectal samples were collected from patients aged ≥ 18 years receiving Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) screening as per local standard of care at sites in Belgium, Germany, Spain, and the UK (Wales). Remnant samples were assessed using the cobas TV/MG assay. Analysis of 2795 samples showed that MG prevalence varied slightly across female sample types (range: 1.7-5.8%; p = 0.0042). MG prevalence was higher in male rectal samples (12.5%) than in male urine samples (3.9%; p < 0.0001). TV prevalence was low in male (0.8%; 12/1535) and female (1.3%; 16/1260) samples across all sites. Co-infection of TV/MG with CT or NG was 10.0% (19/190) and 9.6% (7/73), respectively, in both male and female samples. MG and TV prevalence rates were comparable to the published literature in Europe. MG prevalence was highest in male rectal samples; as rectal testing is an off-label use of the cobas TV/MG assay, the clinical utility of this assay for rectal testing should be further investigated.

Abstract
Sexually transmitted infections are common infectious diseases. The main aim of this study was to perform a comparative analysis of the incidence of bacterial sexually transmitted infections in 2010-2015 in Poland, taking into account the administrative division of the country into provinces. This was a retrospective study. The analysed data came from the Centre for Health Information Systems of the Ministry of Health and constituted information being the epidemiological surveillance system in Poland. The analysis included data on the incidence of primary and secondary syphilis, gonorrhoea and non-gonococcal urethritis and genital infections. The overall incidence rates were disproportionately lower than European rates and those presented in studies from other countries. Young people, between 20 and 29 years of age, were the key groups at the highest risk of infection. The incidence rate of primary and secondary syphilis was lower in Poland than in Europe or America, but some regions, such as Mazovia and Lodz provinces, were found to have a higher incidence rate than other European rates. The reported incidence of gonorrhoea in Poland was also significantly lower compared with other countries, with a significantly higher number of infections in males than in females, and this was also one of the highest rates in EU countries. During the study period, the number of non-gonococcal genital infections systematically decreased, while in other countries of the European region, the incidence was among the highest of all sexually transmitted infections.

Abstract
BACKGROUND No studies have evaluated the utility and risks of screening for Mycoplasma genitalium in men who have sex with men taking preexposure prophylaxis (PrEP). We made use of a quasi-experimental design to evaluate the effect of screening for M. genitalium in a demonstration PrEP cohort with 3-monthly follow-up. METHODS We compared the proportion of PrEP participants with M. genitalium clearance, the duration of persistence, proportion with incident symptoms, the incidence of fluoroquinolone and macrolide resistance, and the proportion of noncleared infections with resistance-associated mutations between 2 groups: those in whom the first episode of M. genitalium was treated and those in whom it was not treated. RESULTS M. genitalium was detected in 70 of 179 individuals. The first episode of infection was treated in 46 individuals. Treatment was not significantly associated with the incidence of symptomatic infections or the acquisition of genotypic resistance. Treatment was associated with a higher probability of clearance of infection but at the expense of increasing the proportion of remaining infections that were resistant. In the nontreated group, the infections that did not clear were less likely to be fluoroquinolone resistant (1/6 [16.7%]) than those that did clear (4/4 [100%]; P = 0.048). In contrast, in the treated group, there was no significant difference in the proportion of fluoroquinolone resistance between the infections that persisted and cleared. CONCLUSIONS If screening and treatment increase the ratio of resistant to susceptible M. genitalium in a population, then this could play a role in the spread of antimicrobial resistance.

Abstract
BACKGROUND Ovarian cancer is one of the most prevalent cancers with a high mortality rate in women. Published studies indicate that inflammation, DNA damage, and pelvic inflammatory disease (PID) are the most important risk factors for ovarian cancer and this could be induced and exacerbated by infectious agents such as Chlamydia trachomatis and Mycoplasma genitalium. The aim of this study was to determine the association between Chlamydia and Mycoplasma infections and the risk of ovarian cancer. METHODS We carried out a comprehensive search of PubMed, Scopus, Web of Science, Embase, and Google Scholar without limitation on publication date. All relevant studies which investigatived probable potential connection between Chlamydia and Mycoplasma infection and development of ovarian cancer were included. RESULTS Eighteen studies comprising a total of 8207 patients were evaluated in the study and this showed that the frequency of infection with Chlamydia and Mycoplasma among ovarian cancer patients was 32.6 % and 23 %, respectively. The results suggested that Chlamydia trachomatis infection increased the overall risk for ovarian cancer by 1.344 fold (OR: 1.344; 95 %CI: 1.19-1.50). Moreover, infection with Mycoplasma infections showed a week but not significant increased risk of ovarian cancer (OR: 1.12; 95 %CI: 0.86-1.44). However, the test for heterogeneity was significant among these studies. CONCLUSION This study confirmed the clinical relevance of Chlamydia and Mycoplasma infection and development of the ovarian cancer risk, although the significance was marginal and study heterogeneity was significant. This highlights the need for further studies in this area.

Abstract
There is a worldwide increase in macrolide-resistant Mycoplasma genitalium strains, with severe impacts on treatment. The aim of this study was to compare three real-time PCR methods for the detection of macrolide resistance: an in-house PCR described by Touati et al., ResistancePlus® MG (SpeeDx), and S-DiaMGRes™ (Diagenode Diagnostics). One hundred M. genitalium-positive patient samples collected in Sweden and a quantitated M. genitalium DNA control were analyzed. Macrolide resistance was detected in 18, 15, and 16 of the samples with the respective methods. Sequencing of the 23S rRNA gene confirmed resistance in 16 (16%) of 100 samples in which it was detected with any of the three methods. ResistancePlus® MG and S-DiaMGRes™ falsely determined one sample as macrolide-sensitive, but this sample was determined as resistant when retested. The sensitivity of the methods was comparable, although there should be awareness of possible incorrect determination of macrolide resistance, especially of low-positive samples.

Abstract
Biometric systems use scanners to verify the identity of human beings by measuring the patterns of their behavioral or physiological characteristics. Some biometric systems are contactless and do not require direct touch to perform these measurements; others, such as fingerprint verification systems, require the user to make direct physical contact with the scanner for a specified duration for the biometric pattern of the user to be properly read and measured. This may increase the possibility of contamination with harmful microbial pathogens or of cross-contamination of food and water by subsequent users. Physical contact also increases the likelihood of inoculation of harmful microbial pathogens into the respiratory tract, thereby triggering infectious diseases. In this viewpoint, we establish the likelihood of infectious disease transmission through touch-based fingerprint biometric devices and discuss control measures to curb the spread of infectious diseases, including COVID-19.

Abstract
The geographic distribution of sexually transmitted infections reflects the underlying social process of sexual partner selection. This qualitative study explored the social geography of partner selection among sexual minority men and used the results to develop a mid-range theory of STI transmission. In-depth interviews with 31 sexual minority men who lived, worked, or socialized in Toronto, Canada, occurred in June and July 2016. Participants were asked how they found sexual partners and reconstructed their egocentric sexual networks for the previous 3 months. Participants described an iterative process of partner selection involving intention (sex versus dating), connecting with community, and selecting a partner based on intersecting partner characteristics (external, internal, and emergent feelings when interacting with potential partners) and personal preferences. Geography influenced partner selection three ways: (1) participant search patterns maximized the number of potential partners in the shortest distance possible; (2) the density of sexual minority men in a participant's community directly impacted participant's social and sexual isolations; and (3) geosexual isolation influenced sexual mixing patterns. Participants described "convection mixing," where assortative urban mixing nested within disassortative suburban mixing resulted in movement from the suburbs to downtown and back to the suburbs. We theorize that convection mixing may be contributing to the persistence of STI epidemics in core and outbreak areas by creating STI reservoirs outside of, and connected to, core and outbreak areas.

Abstract
BACKGROUND Although many species of mycoplasmas regard as normal flora, but some species causes serious genital disease. In Iran several epidemiological studies have documented the prevalence of Mycoplasma hominis, M. genitalium and Ureaplasma urealyticum in genital disorders. This meta-analysis is going to represent the prevalence of M. hominis, M. genitalium and U. urealyticum among Iranian couples and the correlation between mycoplasmas infection and infertility. METHODS We search online databases from January 2000 to June 2019. We used following MeSH keywords (Prevalence, M. hominis, M. genitalium, U. urealyticum, male, female, fertility, Infertility, genitourinary tract infection and Iran) with all possible combinations with "OR" and "AND". Finally, forty-four articles from 2670 were chosen for data extraction and analysis by software using STATA version 14.0. RESULTS This meta-analysis revealed that the prevalence of U. urealyticum was 17.53% in Iran and the prevalence of M. genitalium and M. hominis were 11.33 and 9.68% respectively. The rate of M. genitalium, M. hominis and U. urealyticum infection in women with symptoms of genitourinary tract infection was higher than men with genitourinary tract infection (6.46% vs 5.4, 7.67% vs 5.88 and 21.04% vs 12.13%, respectively). As expected, the prevalence of M. genitalium, U. urealyticum and M. hominis among infertile women (12.73, 19.58 and 10.81%) were higher than fertile women (3%, 10. 85% and 4. 35%). Similarly, the prevalence of M. hominis and U. urealyticum among infertile men (14 and 21.18%) were higher than fertile men (4 and 3%). Based on this analysis, the rate of U. urealyticum was higher than M. genitalium and M. hominis among infertile men and women compared to the fertile group. The prevalence rate of M. genitalium, M. hominis and U. urealyticum in central provinces is higher than other parts of Iran. CONCLUSIONS This meta-analysis reemphasizes a significant relationship between the infertility rate and U. urealyticum, M. genitalium and M. hominis infections. Our finding help to plan the prevalence map of M. hominis, M. genitalium and U. urealyticum in Iran but further studies are needed to suggest routine screening of the pathogens.

Abstract
Worldwide, the incidence of bacterial sexually transmitted infections (STIs) has shown a significant increase in recent years. In Germany, this circumstance is reflected by a rise in the number of reported syphilis cases. There has also been an uptick in the incidence of non-notifiable STIs such as gonorrhea and infections caused by Chlamydia trachomatis and Mycoplasma genitalium. A key factor in the spread of these infections is their varied clinical presentation, which includes urogenital, pharyngeal and rectal involvement as well as a large number of asymptomatic cases. New real-time multiplex PCR methods allow for rapid and targeted detection of STI pathogens. The most common bacterial STI is urogenital chlamydial infection caused by serovars D-K, which affects young adults in particular. Lymphogranuloma venereum (LGV) caused by L serovars often presents as chlamydial proctitis. In recent years, Neisseria (N.) gonorrhoeae has shown a significant development of resistance, with high-level monoresistance and multiresistance to antibiotics commonly used for treatment. It is therefore imperative that sensitivity testing of N. gonorrhoeae be performed in addition to nucleic acid amplification tests (NAATs). Increased drug resistance has also been observed for Mycoplasma genitalium, a fact that complicates treatment.

Abstract
Antibiotic resistance in Mycoplasma genitalium has been emerging in Europe. Also, discrepancies on the management and treatment of sexually transmitted infections may have distinctly influenced the prevalence of antimicrobial resistance among European countries. This comprehensive review of the literature published between 2012 and 2018 updates antimicrobial resistance data in M. genitalium in Europe. Overall, macrolide resistance is rapidly increasing in this region, where many countries are exceeding 50%. The limited data regarding fluoroquinolone resistance estimate a prevalence of 5% (interquartile range, 5–6%). The study supports the need to conduct representative and well-defined surveillance on antimicrobial resistance in M. genitalium at both local and European levels. Also, further investigations on new promising antibiotics are required to fight against M. genitalium that may soon become untreatable.

Abstract
Testing and treatment for Mycoplasma genitalium (MG) infections has recently been facilitated by the increasing availability of molecular tests, but the role of testing in community-based populations is not established. Between 15 May 2017 and 22 November 2017, we tested 561 samples from 547 individuals presenting to primary care in Auckland, New Zealand, requesting investigation for sexually transmitted infections, with concurrent sterile pyuria, using the Aptima MG assay (Hologic, San Diego, CA, USA) in order to establish the prevalence of MG in this group, rates of macrolide resistance and audit primary care’s capacity to manage infections in line with international guidelines. MG was detected in 55 (10%) samples, and co-pathogens were detected in 24 (44%) MG-positive samples. Macrolide resistance mutations were detected in 22/36 (61%) samples subsequently tested using PlexPCR M. genitalium ResistancePlus (Speedx Pvt Ltd., Sydney, Australia). Empiric azithromycin treatment was given to 18 (33%) patients, and test of cure was performed in 15 (27%) patients. Our pilot study demonstrates that sterile pyuria can be a useful marker to direct testing resources in community settings, but highlights important barriers to management of MG in primary care, including clinician knowledge, high prevalence of macrolide resistance and poor completion rates for test of cure.

Abstract
Background The worldwide expansion of macrolide-resistant Mycoplasma genitalium (MG) in cases of genital infections has led to an increased recurrence rate of these infections after first-line azithromycin treatment. By detecting the presence of azithromycin-resistant MG, the patient’s antibiotic treatment can be targeted and the spread of resistance prevented. With this aim in mind, macrolide-resistance detection kits are helpful tools for the physician. Methods Azithromycin resistance mutations in MG are targeted using a four-color multiplex real-time RT-PCR assay. Tested targets include plasmid DNA (as positive controls) as well as macrolide-sensitive and macrolide-resistant genomic DNA from characterized cell lines and clinical samples. Results The analytical data presented here were generated from plasmid DNA and genomic RNA/DNA and include adaptation to an internal control, specificity between targets, specificity vs non-MG species, limit of detection (LoD) and interference studies (co-infection and endogenous substances). The clinical data were based on the application of the assay to clinical samples characterized by sequencing. Conclusions A new NAAT (nucleic acid amplification test) prototype has been developed in collaboration with the Diagenode s.a. company, this prototype targets MG and azithromycin-resistance mutations in that pathogen.

Prevalence of Mycoplasma genitalium and macrolide resistance among asymptomatic people visiting a point of care service for rapid STI screening: a cross-sectional study. Sex Transm Infect 2019; 96:300-305.

Abstract
ObjectivesAlthough rapid screening and treatment programmes have been recently implemented to tackle STIs, testing Mycoplasma genitalium (MG) among asymptomatic populations is not currently recommended due to the lack of scientific evidence and the emergence of antibiotic resistance. The main objective of this study was to estimate the prevalence of MG and macrolide resistance among asymptomatic people visiting a point of care service for rapid STI screening and to identify risk factors associated with the acquisition of this infection.MethodsBetween October 2017 and January 2018, a total of 890 asymptomatic individuals attending to the STI screening service Drassanes Exprés in Barcelona, Spain, were tested for MG and macrolide resistance using the molecular ResistancePlus MG assay (SpeeDx, Australia). Asymptomatically infected individuals were invited to attend the STI Unit for resistance-guided antimicrobial therapy.ResultsOverall, the prevalence of MG was 7.4% (66/890; 95% CI 5.8% to 9.3%), being higher among men who have sex with men (MSM) (46/489) compared with heterosexual men and women (20/401; p=0.012). Macrolide resistance was found in 32/46 (69.6%; 95% CI 54.2% to 82.3%) MSM, while only 2/20 (10.0%; 95% CI 1.2% to 31.7%) infections among heterosexuals presented macrolide resistance-mediated mutations (p<0.001). MSM behaviour, receptive anal intercourse, HIV positive status, syphilis history and high-risk sexual activity (more than five sexual partners in the last 3 months) were significantly associated with MG infection. Furthermore, the resistance-guided therapy approach was implemented in 36/66 (54.6%) individuals.ConclusionsThe research provides further data regarding the prevalence of MG and macrolide resistance among asymptomatic individuals. It also identifies higher risk subpopulations which might be targets for MG screening. Nevertheless, there is insufficient data to justify MG testing among asymptomatic individuals and current STI guidelines should be followed until evidence shows the cost and effectiveness of screening.

Abstract
Bakterielle sexuell übertragbare Infektionen (STI) zeigen seit Jahren weltweit eine deutliche Zunahme. In Deutschland wird diese Tatsache durch steigende Meldezahlen für Syphilis bestätigt. Auch für die nicht meldepflichtigen STI Gonorrhoe, Chlamydia-trachomatis- und Mycoplasma-genitalium-Infektionen wird eine zunehmende Inzidenz beobachtet. Entscheidend für die Weiterverbreitung ist, dass das breite klinische Spektrum, welches neben Urogenitalsitus auch Pharynx und Rektum einbezieht, durch eine hohe Zahl asymptomatischer Verläufe ergänzt wird. Neue Real-Time-Multiplex-Diagnostikverfahren ermöglichen einen schnellen und gezielten Nachweis von STI-Erregern. Die häufigste bakterielle STI ist die urogenitale Chlamydieninfektion mit den Serovaren D-K, die besonders bei jungen Erwachsenen auftritt. Einer Chlamydien-Proktitis kann eine Infektion mit L-Serovaren und damit eine Lymphogranuloma-venereum (LGV)-Infektion zugrunde liegen. Neisseria (N.) gonorrhoeae zeigte in den letzten Jahren eine starke Resistenzentwicklung mit Ausbildung von Einzel- und Multiresistenzen gegenüber bisher gängigen Antibiotika. Daher ist für N. gonorrhoeae zusätzlich zum nucleic acid amplification test (NAAT) eine kulturelle Empfindlichkeitstestung durchzuführen. Auch für Mycoplasma genitalium sind Resistenzentwicklungen bekannt, die eine Therapie erschweren können.

Abstract
This review of the treatment of uncomplicated pelvic inflammatory disease (PID) focuses on the susceptibility profile of the main microbiological causes as well as on the advantages and inconvenients of relevant antibiotics. As bacterial resistance is expanding in the community, the rules of adequate antibiotic prescribing are integrated in the treatment proposals. While the pathogenic role of anaerobic bacteria in uncomplicated PID remains discussed, the choice to provide anaerobes coverage is proposed. Thus, the antibiotic treatment has to cover Chamydia trachomatis, Neisseria gonorrhoeae, anaerobes as well as Streptococcus spp, gram negative bacteria and the ermerging Mycoplasma genitalium. On the basis of published trials and good practice antibiotic usage, the ceftriaxone-doxycycline-metronidazole combination has been selected as the first line regimen. Fluoroquinolones (moxifloxacin alone, or levofloxacin or ofloxacin combined with metronidazole) are proposed as alternatives because of their ecological impact and their side effects leading to restricted usage. When fluoroquinolone are used, ceftriaxone should be added in case of possible sexually transmitted infection. When detected, M. genitalium should be treated by moxifloxacin. Moreover, this review highlights the need to better describe the microbiological epidemiology of uncomplicated PID in France or Europe.

Abstract
OBJECTIVES To determine the procedures for follow-up and counselling of patients after pelvic inflammatory disease (PID). METHODS A search in the Cochrane database, PubMed, and Google was performed using keywords related to follow-up and PID to identify reports published between 1990 and 2018. All studies published in French and English relevant to the areas of focus were included. A level of evidence (LE) based on the quality of the data available was applied for each area of focus and used for the guidelines. RESULTS The rate of recurrent PID is 15 to 21%. They are related to a recurrent sexually transmitted infection (STI) in 20 to 34% of cases. Recurrence PID increase the risk of infertility and chronic pelvic pain (LE2). Follow-up is recommended after PID (grade C). The rate of patients lost to follow-up is around 40%. Follow-up is improved by personalized text message reminders (grade B). Vaginal sampling for detection of N. gonorrhoeae, C. trachomatis, (and M. genitalium) by nucleic acid amplification techniques is recommended 3 to 6 months after treatment of PID associated with STI to rule out possible reinfections (grade C). The use of condoms after PID associated with STI is recommended to reduce the risk of recurrences (grade C). The systematic use of contraceptive pills after PID is not recommended to prevent subsequent infertility and chronic pelvic pain. Vaginal sampling for microbiological diagnosis is recommended before the insertion of an intrauterine device (grade B). The risk of ectopic pregnancy is high in these women and must be kept in mind. CONCLUSION Patient counselling and microbiological testing after PID decrease the risk of STI and thus the recurrence of PID.

Abstract
Macrolide or fluoroquinolone-resistant Mycoplasma genitalium is spreading worldwide. We aimed to determine the influence of single nucleotide polymorphisms (SNPs) in the quinolone resistance determining regions (QRDR) of parC and gyrA in cultured M. genitalium strains. In addition, we examined the prevalence of macrolide- and fluoroquinolone resistance mediating mutations in specimens collected from Japanese male patients with urethritis in two time-periods between 2005–2009 and 2010–2017, respectively, by sequencing the QRDR of parC and gyrA and domain V of the 23S rRNA gene. The minimum inhibitory concentrations (MIC) of moxifloxacin, sitafloxacin, ciprofloxacin, levofloxacin, doxycycline, minocycline, azithromycin and clarithromycin were determined in 23 M. genitalium strains. Three cultured strains had elevated MICs for moxifloxacin at 16, 4 and 2 mg/L and had SNPs with the amino-acid change Ser83→Ile in ParC (p<0.001) and 3 kinds of SNPs with amino-acid changes Asp99→Asn, Gly93→Cys and Met95→Ile in GyrA, respectively. Among a total of 148 M. genitalium positive urine specimens, the prevalence of A2058G and A2059G SNPs in the 23S rRNA gene and any SNPs in ParC increased from 4.8% and 22.6% in 2005–2009 to 42.2% and 53.1% in 2010–2017, respectively. If M. genitalium is considered multi-drug resistant in clinical specimens carrying SNPs in the 23S rRNA gene and Ser83→Ile in ParC, the prevalence of multi-drug resistance is 12.5% in 2010–2017 in Japan. In conclusion, the SNP resulting in Ser83→Ile in ParC is closely related to moxifloxacin resistance even though other factors may also affect treatment outcomes by moxifloxacin. The prevalence of circulating multi-drug resistant M. genitalium strains with macrolide- and fluoroquinolone-resistance is dramatically increasing in Japan.

Abstract
Three-site genital and extragenital screening for Mycoplasma genitalium in 102 asymptomatic Air Force members with human immunodeficiency virus (HIV) infection revealed 19 (18.6%) cases of M. genitalium, commonly (58%) in rectal samples. Because M. genitalium is associated with both HIV acquisition and transmission, these findings suggest that it should be included in routine screening of HIV-infected individuals for sexually transmitted infections.

Abstract
There is increasing concern about Mycoplasma genitalium as a cause of urethritis, cervicitis, pelvic inflammatory disease (PID), infertility and ectopic pregnancy. Commercial nucleic acid amplification tests (NAATs) are becoming available, and their use in screening for M. genitalium has been advocated, but M. genitalium's natural history is poorly-understood, making screening's effectiveness unclear. We used a transmission-dynamic compartmental model to synthesise evidence from surveillance data and epidemiological and behavioural studies to better understand M. genitalium's natural history, and then examined the effects of implementing NAAT testing. Introducing NAAT testing initially increases diagnoses, by finding a larger proportion of infections; subsequently the diagnosis rate falls, due to reduced incidence. Testing only symptomatic patients finds relatively little infection in women, as a large proportion is asymptomatic. Testing both symptomatic and asymptomatic patients has a much larger impact and reduces cumulative PID incidence in women due to M. genitalium by 31.1% (95% range:13.0%-52.0%) over 20 years. However, there is important uncertainty in M. genitalium's natural history parameters, leading to uncertainty in the absolute reduction in PID and sequelae. Empirical work is required to improve understanding of key aspects of M. genitalium's natural history before it will be possible to determine the effectiveness of screening.

Should we screen for the sexually-transmitted infection Mycoplasma genitalium? Evidence synthesis using a transmission-dynamic model. Sci Rep 2017.

Abstract
There is increasing concern about Mycoplasma genitalium as a cause of urethritis, cervicitis, pelvic inflammatory disease (PID), infertility and ectopic pregnancy. Commercial nucleic acid amplification tests (NAATs) are becoming available, and their use in screening for M. genitalium has been advocated, but M. genitalium's natural history is poorly-understood, making screening's effectiveness unclear. We used a transmission-dynamic compartmental model to synthesise evidence from surveillance data and epidemiological and behavioural studies to better understand M. genitalium's natural history, and then examined the effects of implementing NAAT testing. Introducing NAAT testing initially increases diagnoses, by finding a larger proportion of infections; subsequently the diagnosis rate falls, due to reduced incidence. Testing only symptomatic patients finds relatively little infection in women, as a large proportion is asymptomatic. Testing both symptomatic and asymptomatic patients has a much larger impact and reduces cumulative PID incidence in women due to M. genitalium by 31.1% (95% range:13.0%-52.0%) over 20 years. However, there is important uncertainty in M. genitalium's natural history parameters, leading to uncertainty in the absolute reduction in PID and sequelae. Empirical work is required to improve understanding of key aspects of M. genitalium's natural history before it will be possible to determine the effectiveness of screening.

A twelve-year retrospective analysis of prevalence and antimicrobial susceptibility patterns of Ureaplasma spp. and Mycoplasma hominis in the province of Lower Silesia in Poland. Eur J Obstet Gynecol Reprod Biol 2017; 220:44-49. [PMID: 29154180 DOI: 10.1016/j.ejogrb.2017.11.010] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2016] [Revised: 08/21/2017] [Accepted: 11/10/2017] [Indexed: 11/16/2022]
Abstract
OBJECTIVE Genital mycoplasmas are opportunistic pathogens that have been associated with urogenital infections in humans. Only a few groups of antimicrobials are available for treatment of urogenital tract infections caused by genital mycoplasmas. However, emerging resistance of mycoplasmas to antimicrobial agents has been reported worldwide. The aim of the study was a retrospective analysis of the prevalence and antimicrobial susceptibility patterns of M. hominis and Ureaplasma spp. in patients with urogenital tract infections during a twelve-year period between 2003 and 2015. STUDY DESIGN Mycoplasma IST2 test was used for the detection, enumeration, identification and antimicrobial susceptibility testing of genital mycoplasmas in 1182 samples from 778 women and 404 men with genitourinary tract infection. Indicative enumeration in the test determines whether the mycoplasma count in the sample is equal or higher than the threshold set at 104 colony forming units. RESULTS A total of 152 (12.8%) samples were found to be positive for genital mycoplasmas. M. hominis was detected only in three samples and Ureaplasma spp. in 141 samples. Both, M. hominis and Ureaplasma spp. were detected in the remaining eight samples. In the analyzed period between 2003 and 2015, a gradually increasing resistance of ureaplasmas to ciprofloxacin and clarithromycin and decreasing resistance to ofloxacin, erythromycin and tetracycline were observed. Pristinamycin, josamycin and doxycycline were most active against Ureaplasma spp. In contrast, fluoroquinolones had the lowest efficacy against Ureaplasma spp. and as many as 116 (82.3%) and 77 (54.6%) of Ureaplasma spp. isolates were resistant to ciprofloxacin and ofloxacin, respectively. M. hominis isolates were uniformly resistant to azithromycin, clarithromycin and erythromycin but susceptible to josamycin, ofloxacin, doxycycline and pristinamycin. One-third of these isolates were resistant to ciprofloxacin and tetracycline. CONCLUSION In the study Ureaplasma spp. and M. hominis were detected with relatively low frequency in comparison with other studies however, most of these isolates were resistant to ciprofloxacin indicating the need for better management of ciprofloxacin prescription. Important limitations of Mycoplasma IST2 assay concerning antimicrobial susceptibility testing and divergences between breakpoints in the test and EUCAST guidelines point the need to introduce new methodologies to improve evaluation of resistant strains at our region.

Abstract
Mycoplasma genitalium has been associated with infections of the genitourinary tract, and prevalence is secondary to Chlamydia trachomatis The clinical observation of increasing treatment failure indicating antibiotic resistance, especially in cases of recurrent urethritis, has been confirmed by molecular testing. Mutations in the 23S rRNA gene can cause macrolide resistance, and topoisomerase/gyrase mutations can cause fluoroquinolone resistance. In this study, 115 M. genitalium DNA-positive samples were analyzed. Eighty-nine (77.4%) samples had a 23S rRNA mutation present, and 26 (22.6%) were wild type (no resistance mutation). Fluoroquinolone mutation screening was performed on 86 (74.8%) of the 115 samples, of which 20 (23.3%) samples had a mutation or mutations associated with increased resistance. This study shows the increasing antibiotic resistance in New Zealand and the need for appropriate guidelines to treat at-risk patients.

Abstract
Chlamydia trachomatis is the most common pathogen of sexually transmitted bacterial infections worldwide. Every year in Germany approximately 300,000 new infections are to be expected. Chlamydia infections occur nearly exclusively in the postpubertal period. The peak age group is 15-25 years. The infection usually runs an asymptomatic course and the diagnosis is made by nucleic acid amplification techniques (NAAT) often after chlamydial screening or if complications occur. For treatment of chlamydial infections oral doxycycline 100 mg twice daily over 7 days is initially used or alternatively oral azithromycin 1.5 g as a single dose is recommended. The sexual partner should also be investigated and treated. Genital Mycoplasma infections are caused by Ureaplasma urealyticum (pathogen of urethritis and vaginitis), Ureaplasma parvum (mostly saprophytic and rarely a cause of urethritis) and Mycoplasma hominis (facultative pathogenic). Mycoplasma genitalium represents a relatively new sexually transmitted Mycoplasma species. Doxycycline is effective in Ureaplasma infections or alternatively clarithromycin and azithromycin. Doxycycline can be ineffective in Mycoplasma hominis infections and an alternative is clindamycin. Non-gonococcal and non-chlamydial urethritis due to Mycoplasma genitalium can now be diagnosed by molecular biological techniques using PCR and should be treated by azithromycin.

Abstract
M. genitalium is a reemerging microorganism, responsible for sexually transmissible infections (STIs), with prevalence which varies depending on the country and population group studied. We report here M. genitalium prevalence among the specimens received for STI diagnosis in our routine microbiological laboratory in the university hospital in Marseille, France. We tested 4 624 samples from 3 793 patients using qPCR for M. genitalium, C. trachomatis, N. gonorrheae, T. pallidum. Of these samples, 528 (13.6%) patients were tested positive for at least one pathogen and 126 (3.3%) were positive for M. genitalium. M. genitalium is the second most prevalent micro-organism detected in women after C. trachomatis (10.4%) and the third most prevalent in men after C. trachomatis (5.1%) and N. gonorrhoeae (4.4%). We observed no significant differences between the prevalence of M. genitalium in vaginal, urethral and urine specimens (p = 0.9). Prevalence of M. genitalium is significantly higher in patients aged between 10-30 years (4.1%) compared to those aged between 30 and 50 years (2.7%) (p = 0.02, RR = 1.54 [1.06-2.24]) and patients over 50 years of age (1.1%) (p = 0.003, RR= 3.98 [1.47-10.8]). M. genitalium is a common agent of STI, therefore we suggest that this micro-organism should be systematically tested during chronic, recurrent, or antibiotic resistant genital infections and in populations at high-risk of STIs.

Abstract
OBJECTIVES To determine the prevalence and correlates of Mycoplasma genitalium (MG) infection among men and women, determine the prevalence of gene mutations conferring resistance and compare test performance of female specimen types. METHODS A cross-sectional study was conducted on specimens collected for gonorrhoea (NG, Neisseria gonorrhoeae) and chlamydia (CT, Chlamydia trachomatis) among male and female Alberta STI clinic attendees using the M. genitalium transcription-mediated amplification-research use only test. Positive specimens were sequenced for 23SrRNA, parC and gyrA genes. Gender-stratified analysis compared test results using χ2 or Fisher's exact test, Mann-Whitney U test and logistic regression. Female endocervical and urine specimens were compared. RESULTS A total of 2254 individuals were tested; 53.8% (n=1212) were male. Male prevalence of MG was 5.3%; CT was 5.9% and NG was 1.8%. Correlates of male infection were a non-gonococcal urethritis diagnosis and NG coinfection. MG prevalence for women was 7.2%; CT was 5.8% and NG was 1.8%. Correlates of female infection were younger age, Indigenous/Other ethnicity and CT/NG coinfection. Nearly two-thirds of eligible specimens had mutations associated with macrolide resistance and 12.2% of specimens had a parC mutation signifying possible moxifloxacin resistance. There was high concordance (98.1%) of results between urine and endocervical swabs. CONCLUSIONS The high prevalence of MG relative to CT and NG supports the incorporation of MG testing into routine sexually transmissible infection screening. The high rate of resistance to macrolides and moxifloxacin raises concerns about treatment options. The good concordance of results between urine and endocervical swabs supports the use of female urine specimens for testing.
