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)
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)
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)
Strongyloides stercoralis is an intestinal nematode, which can cause complications in immune-compromised hosts. We present a rare case of intestinal obstruction due to mesenteric lymphadenopathy, a complication due to strongyloidiasis, developing in a male subject chronically receiving corticosteroid for pemphigus vulgaris. DNA was extracted from biopsied(More)
Human strongyloidiasis is a deleterious gastrointestinal disease mainly caused by Strongyloides stercoralis infection. Strongyloides stercoralis is a soil-transmitted helminthiasis that is distributed around the globe. Although definitive diagnosis is carried out through the detection of parasite objects in human stool samples, the development of reliable(More)
Previously, we reported the presence of imported trichinellosis in a Thai worker returning from Malaysia, who presented with progressive generalized muscle hypertrophy and weakness after eating wild boar meat. This work analyzed a partial small subunit of a mitochondrial ribosomal RNA gene of Trichinella larvae isolated from the patient. The results showed(More)
Human sparganosis is one of the neglected diseases but important food-borne parasitic zoonoses. The disease is caused by larvae (spargana) of diphyllobothriidean tapeworm. Here, we describe nine cases of human sparganosis, caused by Spirometra erinaceieuropaei in a hospital in Thailand during 2001-2012. Clinical characteristics, treatment, and outcome of(More)
PCR amplification coupled with pyrosequencing was used to measure molecular markers that could be used to detect and differentiate Plasmodium falciparum and Plasmodium vivax in human blood samples. The detection rates were in agreement with the results of Giemsa-stained film microscopy, which is the current gold standard for detection. This method provides(More)
DNA pyrosequencing for PCR amplicons is an attractive strategy for the identification of microorganisms because of its short time performance for large number of samples. In this study, the primers targeting the fragment of ITS2 region of nuclear ribosomal RNA gene were newly developed for pyrosequencing-based identification of 6 Paragonimus species,(More)
