Lymphogranuloma venereum (LGV) has been increasingly reported, and many clinicians are familiar with it as a cause of proctocolitis or inguinal adenopathy. On the other hand, LGV is less commonly considered as a cause of isolated genital ulcerative disease in comparison to other etiologies such as syphilis or herpes simplex. We report a case of persistent perianal ulcerations due to LGV in an HIV-positive patient, confirmed by nucleic acid amplification testing. Read More

Previously, we identified a Chlamydia trachomatis Lymphogranuloma venereum (LGV) recombinant strain possessing a unique non-LGV ompA genotype. Here, culture-independent genome sequencing confirms its circulation in Europe, Middle East and North America, and unveils genetic evidence of emergence of antibiotic resistance. Multi-country and systematic molecular surveillance is needed. Read More

Aims: Recent studies from multiple global regions have reported a resurgence of lymphogranuloma venereum (LGV) proctitis, which is caused by Chlamydia trachomatis (CT). LGV proctitis is histologically indistinguishable from other forms of sexually transmitted proctitis and is difficult to differentiate from inflammatory bowel disease. While immunohistochemical stains are available for syphilis, there is no commonly available stain for the tissue identification of CT. Read More

Objectives: Lymphogranuloma venereum (LGV) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis (CT) genovars L. The identification of LGV is of therapeutic interest because treatment requires 3 weeks of doxycycline compared with 1 week for infection with a non-L strain. The aim of this study was to evaluate the performance of four commercial real-time PCR kits in comparison with the reference methods used for LGV diagnosis by the French National Reference Centre (NRC) for bacterial STIs.

Background Following an upward trajectory in Lymphogranuloma venereum (LGV) diagnoses in the UK from 2004 to 2016, with annual diagnoses increasing from 28 to 904, diagnoses fell to 641 in 2017; this was inconsistent with the upward trend in other bacterial sexually transmissible infections (STIs) between 2016 and 2017. An analysis of surveillance data from multiple sources to investigate the possible factors contributing to this decline in LGV was performed.

Methods: LGV tests and diagnoses in the UK from 2004 to 2018 were captured through laboratory data from the LGV Reference Laboratories and laboratories conducting in-house LGV testing. Read More

Objectives: Typing of Chlamydia trachomatis (CT) is traditionally performed by characterising the ompA gene, resulting in more than a dozen different genovars, A to L. Type L is associated with Lymphogranuloma venereum (LGV) and commonly screened for using PCR, targeting the chromosomal pmpH gene. We aimed to develop and validate a new CT/LGV plasmid-based typing assay targeting the pgp3 gene, to increase sensitivity and thus reduce the number of non-typeable results. Read More

) is an obligate intracellular pathogen that cannot be cultured axenically and must be propagated within eukaryotic host cells. There are at least 15 distinct chlamydial serovariants that belong to 2 major biovars commonly referred to as trachoma and lymphogranuloma venereum (LGV). The invasive chlamydia LGV serovar L2 is the most widely used experimental model for studying biology and infection and is the only strain with reliable genetic tools available. Read More

Purpose Of Review: Recent studies regarding the frequency of Chlamydia-induced reactive arthritis (ReA) are reviewed, with a focus on the question of whether the entity is in fact disappearing or whether it is simply being underdiagnosed/underreported. Epidemiological reports indicate diversity in the frequency of Chlamydia-associated ReA in various parts of the world, with evidence of declining incidence in some regions.

Recent Findings: The hypothesis that early effective treatment with antibiotics prevents the manifestation of Chlamydia-associated ReA requires further investigation. Read More

is the most prevalent sexually transmitted bacterium worldwide and the causative agent of trachoma. Its strains are classified according to their genotypes, which are strongly linked to differential tissue tropism and disease outcomes [ocular disease, urogenital disease and lymphogranuloma venereum (LGV)]. While the genome-based species phylogenetic tree presents four main clades correlating with tropism/prevalence, namely ocular, LGV, urogenital T1 (more prevalent genotypes) and urogenital T2 (less prevalent genotypes), inter-clade exchange of is considered a rare phenomenon probably mediating marked tropism alterations.

New or important issues in this updated version of the 2013 European guideline on the management of lymphogranuloma venereum (LGV): EPIDEMIOLOGY: Lymphogranuloma venereum continues to be endemic among European men who have sex with men (MSM) since 2003. Lymphogranuloma venereum infections in heterosexuals are extremely rare in Europe, and there is no evidence of transmission of LGV in the European heterosexual population.

Aetiology And Transmission: Chlamydia trachomatis serovars/genovars L2b and L2 are the causative strains in the majority of cases in Europe. Read More
