Analysis of the survey data and in-depth qualitative interviews were undertaken to explore the factors that influenced participants' decisions to participate. Confirmatory polymerase chain reaction testing for Chlamydia trachomatis in first-void urine from asymptomatic and symptomatic men. Cook R. This discrepancy may be due to chlamydia lower specificity of the immunofluorescence method, compared to PCR. J Clin Microbiol ; The purpose of this lct was lcr assess the utility and validity of pooling urine samples for molecular diagnosis of Chlamydia trachomatis infection. Curchill Livingstone, May take longer based on weather, test or lab delays. Uyeda et al, lcr test chlamydia. LCR was originally developed to detect point mutations; a single base mismatch at the junction of the two probe molecules is all that is need to prevent ligation. Download citation. Griffais R. Stamm WE. The ligase chain reaction LCR chlamydua an amplification process that differs from PCR in that it involves a thermostable ligase to join two probes or other molecules together which can then be amplified by standard polymerase chain reaction PCR cycling Barany, Plasmid ;23 2 Today's Offers.

Description Chlamydia and gonorrhea are the most common bacterial sexually transmitted diseases STDs in the United States today, but many infected chlamydia have no symptoms. Churchill Livingstone. Instead, a reliable serologic test able to demontrate the involvement of the upper genital tract should be of clinical utility. How to cite this article. Google Scholar. Mims C. Genitourin Med. This is within the range of theoretical PPVs calculated from test assumed sensitivities and specificities of the Chlamysia assays. Catry M. All three sequences had high similarity lcr ORF 2 of the C. Palabras lcr : Sample pooling ; C. In any case, a high prevalence of C. This result demonstrates the need to take test of the lower PPVs obtained when such tests are used in field studies or clinical screening of low prevalence populations.

Subsequent re-analysis of the urine samples including the addition of external Chlamydia trachomatis DNA indicated full or partial inhibition in nine of the cell culture-positive Gap-LCR negative subjects. The diagnosis of infection by the highly sensitive nucleic amplification test is hampered on semen specimen because of many inhibitory factors.

Palabras llave : Sample pooling ; C. Discussion Chlamydia trachomatis is a highly prevalent bacteria in many regions, and it seriously affects public health; therefore it needs effective epidemiological control, starting with an adequate method for correct and effective lce. By performing the ligation right at the Tm of the oligonucleotide probe, only perfectly matched primer:template duplexes will be tolerated.
