The Uppsala University Chlamydia trachomatis multilocus sequence type database (http://mlstdb.bmc.uu.se) is based on five target regions (non-housekeeping genes) and the ompA gene. Each target has varying numbers of alleles: hctB, 89; CT058, 51; CT144, 30; CT172, 38; and pbpB, 35, derived from 13 studies. Our aims were to perform an overall analysis of all C. trachomatis MLST sequence types (STs) in the database, examine STs with global spread, and evaluate the phylogenetic capability by using the five targets. A total of 415 STs were recognized from 2089 specimens. The addition of 49 ompA gene variants created 459 profiles. ST variation and their geographical distribution was characterized using eBURST and minimum spanning trees analyses. There were 609 samples from men having sex with men (MSM) with 4 predominating STs detected in this group, comprising 63% of MSM cases. Four other STs predominated among 1383 heterosexual cases comprising 31% of this group. The diversity index in ...

Chlamydia trachomatis is the principal infectious cause of blindness in the world, which begins as follicular conjunctivitis. In Peru few studies was realized by its difficulty to diagnose. A study was conducted in 55 patients 18 to 68 years with follicular conjunctivitis treated at the Instituto Nacional de Oftalmología (Lima, Peru) during the years 2005 and 2006, with the objective of determining the prevalence of Chlamydia trachomatis and evaluated the usefulness of Giemsa and direct immunofluorescence (DIF) for the diagnosis of C. trachomatis in relation to cell culture. The frequency of C. trachomatis in samples of eyes secretions was 13% (7/55) for cell culture, 20% (11/55) for DIF and 9% (5/55) for Giemsa; the signs and symptoms more frequents were the presence of secretions and photophobia. All cases were males and reported not having had prior sexually transmitted infections. We found a sensitivity of 42,9 and 85,7%, and a specificity of 98,8 and 89,6% for Giemsa and DIF re...

Bacterial infections represent a major health problem, especially in third world countries. In endemic regions, large populations of people are greatly affected, but the medical care is very limited. In this review, the neglected diseases buruli ulcer and trachoma are elucidated. Buruli ulcer is caused by Mycobacterium ulcerans which produces an outstanding immunosuppressive toxin mycolactone that induces an ulcerative, necrotic skin disease. Until today, only the combination of rifampin/streptomycin is used to treat buruli ulcer. However, this therapy is ineffective and expensive. Here, we report new findings that suggest pharmaceutical formulations such as rifapentine, in combination with clarithromycin or moxifloxacin that have shown promising results in mice footpad trials. Moreover, alternative treatment options such as heat therapy, nitric oxide cremes and French clay show bactericidal effects. The genotyping of M. ulcerans also promises new ways of finding drug targets and vaccines. Trachoma, induced by the bacterium Chlamydia trachomatis, is the primary infectious cause of blindness worldwide. Recurrent infections lead to chronic inflammation of the upper tarsal conjunctiva. As a consequence, scarring and distortion of the eye lids occur, eventually resulting in blindness. First-line medications for trachoma treatment are bacteriostatic agents such as topically applied tetracylines and systematically administered azithromycin. Surgery, environmental improvements and personal hygiene are further crucial factors in controlling trachoma. Moreover, efforts are being undertaken towards the development of vaccine systems, with the major outer membrane protein and the polymorphic membrane protein acting as attractive candidates.

Urethritis is one of the most important causes of morbidity and mortality in developing countries. The aim of this study was to detect common bacterial causes of urethritis in men by Gram stain, culture and multiplex PCR.185 male patients who presented at the Skin and venereal clinic of the Dhaka Medical College, Bangladesh with clinical symptoms suggestive of urethritis were enrolled in this study. Urethral discharges were tested for detection of Neisseria gonorrhoeae by Gram stain, culture and PCR. Multiplex PCR assay was done to detect DNA of Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma genitalium. Out of 185 participants, 30.27% and 14.6% were infected by Neisseria gonorrhoeae and Chlamydia trachomatis respectively. None of the individuals was found positive for either Ureaplasma urealyticum or Mycoplasma genitalium. Among the Neisseria gonorrhoeae positive patients 27.57% were positive from Gram stain, 26.49% were culture positive, 30.27% were positive by PCR (p...

The sexual health needs of teenagers differ from those of adults. Young sexually active teenagers are at high risk of Chlamydia trachomatis genital infection and its complications. Teenage pregnancy continues to be a problem in Australia. Current preventive strategies and clinical services in this domain of adolescent health in Australia are deficient. Australia can learn from the innovative and effective strategies developed in various countries for preventing high-risk sexual behaviours in teenagers.
