Paragonimiasis is an important food-borne parasitic zoonosis caused by infection with lung flukes of the genus Paragonimus. In Southeast Asia, Paragonimus heterotremus is the only proven causative pathogen. Recently, a new Paragonimus species, P. pseudoheterotremus, was found in Thailand. This species is genetically similar to P. heterotremus and is(More)
Human trichostrongylosis has been reported in Thailand. Recent reports in Lao People's Democratic Republic concerning species identification urged us to investigate species distribution in Thailand. We report eight human cases in Thailand and Lao People's Democratic Republic that were found to be infected by Trichostrongylus colubriformis and T. axei(More)
Human opisthorchiasis caused by the liver fluke Opisthorchis viverrini is an endemic disease in Southeast Asian countries including the Lao People’s Democratic Republic, Cambodia, Vietnam, and Thailand. Infection with the soil-transmitted roundworm Strongyloides stercoralis is an important problem worldwide. In some areas, both parasitic infections are(More)
We developed a single-step real-time fluorescence resonance energy transfer (FRET) multiplex polymerase chain reaction (PCR) merged with melting curve analysis for the detection of Wuchereria bancrofti and Brugia malayi DNA in blood-fed mosquitoes. Real-time FRET multiplex PCR is based on fluorescence melting curve analysis of a hybrid of amplicons(More)
Real-time fluorescence resonance energy transfer (FRET) polymerase chain reaction (PCR) supplemented with melting curve analysis is a highly sensitive and fast method offering a high throughput. We report the development of a real-time FRET PCR for molecular detection of Opisthorchis viverrini in human fecal samples. The diagnostic sensitivity, specificity,(More)
We developed real-time fluorescence resonance energy transfer (FRET) polymerase chain reaction (PCR) combined with melting curve analysis for detection of Brugia malayi DNA in blood-fed mosquitoes. Real-time FRET PCR is based on a fluorescence melting curve analysis of hybrid formed between amplicons generated from a family of repeated DNA element, 153-bp(More)
A simple, rapid, and high-throughput method for detection and identification of Wuchereria bancrofti, Brugia malayi, Brugia pahangi, and Dirofilaria immitis in mosquito vectors and blood samples was developed using a real-time PCR combined with high-resolution melting (HRM) analysis. Amplicons of the 4 filarial species were generated from 5S rRNA and(More)
Naturally occurring bithyniid snails, Bithynia siamensis goniomphalos (Prosobranchia: Bithyniidae), and their intermediate hosts were sampled from Khammouane Province, the Lao People's Democratic Republic, and the prevalence of the carcinogenic human liver fluke, Opisthorchis viverrini, was examined. The presence of O. viverrini cercariae in snails was(More)
A real-time fluorescence resonance energy transfer (FRET) PCR supplemented with melting curve analysis for the rapid molecular detection of Dirofilaria immitis in mosquito vectors and dog blood samples was developed. This real-time FRET PCR was based on the fluorescence melting curve analysis of a hybrid between an amplicon generated from the D. immitis(More)
We developed a single step duplex real-time fluorescence resonance energy transfer (FRET) PCR merged with melting curve analysis for the fast detection and differentiation of Clonorchis sinensis and Opisthorchis viverrini eggs in human fecal samples. Two species of mitochondrial NADH dehydrogenase subunit 2 (nad2) DNA elements, the 165-bp nad2 product of C.(More)
