Sensitive detection and typing of Chlamydia trachomatis using nested polymerase chain reaction.

Sensitive detection and typing of Chlamydia trachomatis using nested polymerase chain reaction.

OBJECTIVES A method based on a nested polymerase chain reaction (PCR) was developed to detect and to type Chlamydia trachomatis from low titre samples by amplifying a large portion of the major outer membrane protein gene. The sensitivity of this procedure was evaluated in urogenital clinical samples in comparison with culture. SPECIMENS A series of 787 urogenital specimens, including 37 (4.7...

Detection of Chlamydia trachomatis Using polymerase chain reaction (PCR)

Chlamydia trachomatis now is one of the most prevalent bacteria sexually transmissible diseases (STD), and as such, constitutes a serious public health problem. Diagnosis of Chlamydial infections is based on isolation of bacteria in tissue culture media that requires at least 48 to 72h. The aim of this study was the detection of Chlamydia trachomatis, using polymerase chain reaction (PCR), beca...

One-tube nested polymerase chain reaction for detection of Chlamydia trachomatis.

Here we present a one-tube nested PCR test, which allows the detection of minimal quantities of Chlamydia trachomatis in human fluids. This assay includes the use of an internal control to avoid false negative results due to the presence of inhibitors. The results obtained show that this assay is robust enough to be used for clinical diagnosis.

Detection of Chlamydia trachomatis DNA in patients with non-gonococcal urethritis using the polymerase chain reaction.

A practical protocol using the polymerase chain reaction (PCR) was designed for detecting Chlamydia trachomatis in clinical samples. DNA was extracted from material collected on urethral swabs and used as substrate for the PCR. The target was a 600 basepair DNA segment of the multicopy plasmid that is common to all strains of the bacterium. Negative samples were checked for loss of DNA or prese...
