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 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...

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...

Optimised sample preparation of synovial fluid for detection of Chlamydia trachomatis DNA by polymerase chain reaction.

OBJECTIVE To optimise sample preparation of synovial fluid for Chlamydia trachomatis (CT) specific polymerase chain reaction (PCR). METHODS Serial dilutions of purified CT elementary bodies in synovial fluid were prepared. The synovial fluid pellet was processed by eight different methods of sample preparation. Then samples were analysed by CT specific PCR. The sensitivity of PCR was the basi...

Polymerase chain reaction for detection of Chlamydia trachomatis in conjunctival swabs.

AIMS/BACKGROUND Ocular Chlamydia trachomatis infection in the west occurs as opthalmia neonatorum, acquired from the mother, or adult paratrachoma which is also associated with current genital tract infection. Accurate rapid laboratory diagnosis facilitates management, but the relative merits of antigen detection or DNA amplification tests are unresolved. METHODS A polymerase chain reaction (...
