چکیده

A variant of Chlamydia trachomatis that had escaped detection by commonly used systems was discovered in Sweden in 2006. In a nationwide study, we found that it is now prevalent across Sweden, irrespective of the detection system used. Genetic analysis by multilocus sequence typing identified a predominant variant, suggesting recent emergence.

French situation concerning the Swedish Chlamydia trachomatis variant.

In 2006, a plasmid deletion mutant of Chlamydia trachomatis was identified in Sweden that can not be detected with those commercial tests targeting the deleted area. In order to study the spread of this strain in France, a laboratory-based surveillance system was set up by the National Reference Centre for Chlamydiae and the Institut de Veille Sanitaire. Among 1,141 C. trachomatis-positive spec...

Prevalence of Chlamydia trachomatis Antigen and Antibody in Infertile Women in Ahwaz

Chlamydia trachomatis is an obligate intracellular bacterium which causes a wide variety of human infections such as ocular, urogenital and respiratory infections. Genital infections of women, espe-cially when repeated, give rise to many complications such as ectopic pregnancy, miscarriage and in‌fertility. Since chlamydial infections are usually asymptomatic, they progress unnoticed and produc...

Comparison of the Abbott RealTime CT new formulation assay with two other commercial assays for detection of wild-type and new variant strains of Chlamydia trachomatis.

In an analytical-method comparison study of clinical samples, the Abbott RealTime CT new formulation assay (m2000 real-time PCR), consisting of a duplex PCR targeting different parts of the cryptic plasmid in Chlamydia trachomatis, was compared both with version 2 of the Roche Cobas TaqMan CT assay, comprising a duplex PCR for a target in the cryptic plasmid and the omp1 gene, and with the Gen-...

Decrease in number of genital chlamydia cases in Norrbotten, Sweden, October - November 2009: an indirect effect of pandemic influenza A(H1N1)?

A sudden reduction in the number of reported genital chlamydia cases was observed in Norrbotten County, Sweden, during October to November 2009. After exploring other possibilities, such as a reduction in the number of chlamydia tests analysed or a new Chlamydia trachomatis variant that had been undetected in standard laboratory tests, it was found likely that the decrease was an indirect effec...

Ten years transmission of the new variant of Chlamydia trachomatis in Sweden: prevalence of infections and associated complications

OBJECTIVES In 2006, a new variant of Chlamydia trachomatis (nvCT) was discovered in Sweden. It has a deletion in the plasmid resulting in failed detection by the single target systems from Abbott and Roche used at that time, whereas the third system used, from Becton Dickinson (BD), detects nvCT. The proportion of nvCT was initially up to 65% in counties using Abbott/Roche systems. This study a...
