A multiplex PCR designed to differentiate Mycobacterium tuberculosis complex organisms from M. avium and M. intracellulare was used to test 105 isolates identified by DNA probe methods as M. avium, M. intracellulare, or M. avium complex type X. The multiple PCR correctly identified 33 of 34 isolates identified by commercial probe methods as M. avium and all 51 isolates identified as M. intracel...

A multiplex PCR assay consisting of 13 Rapidly Mutating Y STR loci called RM-Yplex was developed. Platinum® Taq DNA polymerase was used to amplify the 13 Y STR loci in a single reaction in approximately 2.5 hours . In order to shorten the process with reliable results, several DNA polymerases were tested with the multiplex. Phusion® Flash High Fidelity and Platinum® Taq DNA polymerases were inv...

Bacteriological culture was compared with multiplex and fluorogenic (TaqMan) polymerase chain reaction (PCR) assays for the detection of attachment invasion locus (ail)-bearing Yersinia enterocolitica in market weight swine, chitterlings, and ground pork. The TaqMan assay detected 1 pg of purified Y. enterocolitica DNA, whereas conventional gel-based PCR detected I ng of the same. The presence ...

This study explored epidemiological trends in trichomoniasis in Daegu, South Korea. Wet mount microscopy, PCR, and multiplex PCR were used to test for Trichomonas vaginalis in vaginal swab samples obtained from 621 women visiting 2 clinics in Daegu. Of the 621 women tested, microscopy detected T. vaginalis in 4 (0.6%) patients, PCR detected T. vaginalis in 19 (3.0%) patients, and multiplex PCR ...

BACKGROUND Due to an increasing number of norovirus infections in the last years rapid, specific, and sensitive diagnostic tools are needed. Reverse transcriptase-polymerase chain reactions (RT-PCR) have become the methods of choice. To minimize the working time and the risk of carryover contamination during the multi-step procedure of PCR the multiplex real-time RT-PCR for the simultaneous det...

clostridium perfringens (c. perfringens) is related to gram-positive and anaerobic bacteria. this rod-shaped bacterium produces spores and can cause a wide spectrum of diseases in humans and animals. every of five different bacterium types can lead to different diseases. most of distinct bacterial recognition methods are not completely effective and practical in all condition. the objective of ...
