Chlamydia trachomatis, Mycoplasma spp., Neisseria gonorrhoeae and Treponema pallidum are sexually transmitted pathogens that threaten reproductive health worldwide. In this study, vaginal swabs obtained from women (n = 133) that attended an infertility clinic in China were tested with qPCRs for C. trachomatis, Mycoplasma spp., N. gonorrhoeae, T. pallidum and tetracycline resistance genes. While none of vaginal swabs were positive for N. gonorrhoeae and T. pallidum, 18.8% (25/133) of the swabs were positive for Chlamydia spp...

BACKGROUND: Henoch-Schönlein purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis involving the capillaries and by the deposition of IgA immune complexes. An association between HSP and atypical bacteria is uncommon in children. METHODS AND RESULTS: Here we report three cases of children, aged 5, 4 and 16 years, who were diagnosed with HSP associated with Mycoplasma pneumoniae or Chlamydia pneumoniae infection. In all presented cases, persistent cutaneous manifestations and abdominal pain were resistant to antibiotics and corticosteroids, but resolved during 48 h after the introduction of dapsone...

Sterile pyuria is a highly prevalent condition with a wide aetiological spectrum, which often challenges the diagnostician. We describe the case of a middle-aged female admitted to the medical Intensive Care Unit for acute gastroenteritis, whose urinalysis revealed persistent sterile pyuria. Polymerase chain reaction assay in urine was positive for Chlamydia trachomatis and Mycoplasma hominis. She responded to antimicrobial therapy. We hereby reflect on the approach to a case of sterile pyuria and review the available literature on this entity...

Before 1945, Streptococcus pneumoniae caused more than 90% of cases of pneumonia in adults. After 1950, the proportion of pneumonia caused by pneumococcus began to decline. Pneumococcus has continued to decline; at present, this organism is identified in fewer than fewer10%-15% of cases. This proportion is higher in Europe, a finding likely related to differences in vaccination practices and smoking. Gram-negative bacilli, Staphylococcus aureus, Chlamydia, Mycoplasma, and Legionella are each identified in 2%-5% of patients with pneumonia who require hospitalization...

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...

In order to identify the groups at risk of sexually transmitted diseases (STDs), we assessed the sociodemographic profiles of men testing for STD, their sexual habits, and the results of microbiological analysis. During a three-year period, a total of 700 men older than 18 years of age completed the questionnaire regarding sociodemographic and sexual behavior. Urethral swabs were taken for microbiological analysis. Thirty-three percent of respondents reported not using condoms. Those that do not use condoms were predominantly less educated, unmarried but in steady relationships, employed, with children, and smokers...

The antimicrobial activity of bitespiramycin (BT) against Chlamydia trachomatis (Ct), Chlamydia pneumoniae (Cp), Ureaplasma urealyticum (Uu), and Mycoplasma pneumoniae (Mp), was compared with those of azithromycin (AZM) and acetylspiramycin (AT-SP) in vitro. Furthermore, the anti-Mp activities of BT and AZM were evaluated in a hamster model. The activities of BT in vitro were similar to those of AZM but were more effective than those of AT-SP. BT effectively inhibited Mp infection at a dose of 200mg/kg in a hamster model...

Health consequences of sexually transmitted diseases disproportionately affect women, making it important to determine whether newly emerged pathogens cause sequelae. Although the pathogenic role of Mycoplasma genitalium in male urethritis is clear, fewer studies have been conducted among women to determine its pathogenic role in the female reproductive tract. Pelvic inflammatory disease (PID) is an important cause of infertility and ectopic pregnancy, and Chlamydia trachomatis and Neisseria gonorrhoeae are recognized microbial causes...

Chris L McGowin, Patricia A Totten
Mycoplasma genitalium is increasingly appreciated as a common cause of sexually transmitted disease syndromes, including urethritis in men and cervicitis, endometritis, pelvic inflammatory disease, and possibly preterm birth, tubal factor infertility, and ectopic pregnancy in women. Despite these disease associations, which parallel those of Chlamydia trachomatis and Neisseria gonorrhoeae, the mechanisms by which this pathogen elicits inflammation, causes cellular damage, and persists in its only natural host (humans) are unique and are not fully understood...

REVIEW
Patrick J Horner, David H Martin
Mycoplasmagenitalium is one of the major causes of nongonococcal urethritis (NGU) worldwide but an uncommon sexually transmitted infection (STI) in the general population. The risk of sexual transmission is probably lower than for Chlamydia trachomatis. Infection in men is usually asymptomatic and it is likely that most men resolve infection without developing disease. The incubation period for NGU caused by Mycoplasma genitalium is probably longer than for NGU caused by C. trachomatis. The clinical characteristics of symptomatic NGU have not been shown to identify the pathogen specific etiology...
