In this study, two new duplex PCR methods based on the groEL gene were developed and investigated for the diagnosis of rickettsiae. The first duplex PCR assay amplified the 229-bp and the 366-bp DNAs of 6 strains including typhus group (TG) and spotted fever group (SFG) rickettsiae, and 5 scrub typhus group (STG) rickettsiae, respectively. The second duplex PCR assay amplified the 397-bp and th...

Background and Objective: Sexually infections transmitted by bacteria are one of thetherapeutic and social problemsworldwide. The Real-time PCR assay is one of the most sensitive diagnostic and screening methods for these infections. The purpose of this study wassimultaneous detection of Chlamydia trachomatis and Mycoplasma genitaliumusing the TaqMan duplex real-time polymerase chain reaction. ...

materials and methods in silico analysis of the cadf gene was carried out by several software and available online tools. a duplex pcr optimized with specific primers was used for detection and differentiation of both species. to evaluate specificity and sensitivity of the test, a panel of different campylobacter spp. together with several intestinal bacterial pathogens was tested. the limit of...

Duplex PCR was developed to screen Salmonella enterica serovar Typhimurium phage type DT104 and related strains in Thailand because a phage typing laboratory of serovar Typhimurium is not available. Of 46 isolates of serovar Typhimurium and 32 isolates of S. enterica serovar 1,4,[5],12:i:-, 15 (33%) and 30 (94%) were duplex PCR positive, respectively. All isolates were submitted for phage typin...

Adulteration of high quality meat with their inferior/cheaper counterparts has become a common practice in the meat industry, which is not detectable by the naked eye or by eating. To circumvent this problem, molecular methods had been developed. The present study was carried out for detection of meat species with the use of cytochrome b gene variability by duplex PCR. Meat samples from goat, s...

Recent outbreaks of porcine epidemic diarrhea virus (PEDV) and porcine deltacoronavirus (PDCoV) in multiple countries have caused significant economic losses and remain a serious challenge to the swine industry. Rapid diagnosis is critical for the implementation of efficient control strategies before and during PEDV and PDCoV outbreaks. Insulated isothermal PCR (iiPCR) on the portable POCKIT™ d...

BACKGROUND Duplex real-time PCR assays have been widely used to determine amounts and concentrations of free circulating DNA in human blood plasma samples. Circulatory plasma DNA is highly fragmented and hence a PCR-based determination of DNA concentration may be affected by the limited availability of full-length targets in the DNA sample. This leads to inaccuracies when counting PCR target co...

Background: Pseudomonas aeruginosa (P. aeruginosa) is a ubiquitous bacterium which can be found in most moisture places such as soil, water, food, plants, and animals including humans. Due to genetic flexibility among strains, there is no standard molecular identification for P. from different sources, particularly human colonizing or commensal isolates. Materials Method: Monoplex PCR usin...
