Schistosomes are digenean flukes, parasitic of birds, mammals and crocodiles. The family Schistosomatidae contains species considerable medical veterinary importance, which cause the disease schistosomiasis. Previous studies, both morphological molecular, have provided a good deal information on phylogenetics this group, been limited in number investigated or type extent molecular data used. This paper presents most comprehensive phylogeny to date, based sequences 3 genes, complete ribosomal...
[Extract] Mitochondrial genomes have been used in numerous studies to investigate phylogenetic relationships among eukaryotes at many levels (e.g., Smith et al. 1993; Boore 1995; Boore, Lavrov, and Brown 1998). In recent years, the arrangement of genes mitochondrial genome has regarded as a powerful record historical (Boore 1999). Changes gene order are infrequent, even over considerable spans time 1999), unlikely exhibit homoplasy. Our research focused on between two groups human blood...
Nucleotide sequences were obtained for the second internal transcribed spacer of ribosomal gene repeat and part mitochondrial cytochrome c oxidase subunit I from geographical isolates Paragonimus westermani Japan, China, Korea, Taiwan, Philippines, peninsular Malaysia Thailand. Sequences several other species comparative purposes. Two groups recognized within P. : an NE group (China, Taiwan) which was relatively uniform included both diploid triploid forms, a southern (Malaysia, Thailand,...
Abstract Background Foodborne infections caused by lung flukes of the genus Paragonimus are a significant and widespread public health problem in tropical areas. Approximately 50 species have been reported to infect animals humans, but westermani is responsible for bulk human disease. Despite their medical economic importance, no genome sequence any available. Results We sequenced assembled P. westermani, which among largest known pathogen genomes with an estimated size 1.1 Gb. A 922.8 Mb...
Abstract Background Bithynia spp., a key intermediate host of Opisthorchis viverrini , is widely distributed in the lower Mekong sub-region, where opisthorchiasis remains major public health concern. Understanding genetic diversity and population structure these snails crucial for disease control. siamensis sensu lato has been classified into three lineages (I–III) based on cytochrome c oxidase subunit 1 ( cox1 ) 16S ribosomal RNA (16S rRNA) sequence analysis. This study focuses Champasak...
The first internal transcribed spacer (ITS1) of the nuclear ribosomal DNA repeat was sequenced for members Schistosoma japonicum species complex ( S. malayensis , mekongi and 2 geographical isolates ). ITS1 is composed 3 distinct regions: 5′ end (23 nucleotides); a tract approximately 90–140 nucleotides, which occurs up to 7 times in tandem, number varying even within an individual all investigated this study; 3′ region (378 nucleotides), lacks repeats. There size sequence variation among...

Abstract The lung fluke, Paragonimus westermani (Kerbert, 1878), is widely distributed in Asia, and exhibits much variation its biological properties. Previous phylogenetic studies using DNA sequences have demonstrated that samples from north-east Asia form a tight group distinct south (Philippines, Thailand, Malaysia). Among countries the latter region, considerable molecular diversity was observed. This investigated further additional (partial mitochondrial cytochrome c oxidase subunit 1...
Three dog heartworms (Dirofilaria immitis) were detected in the lumen of right cardiac ventriculus and pulmonary artery a captive female snow leopard (Uncia uncia) that died pancreatic carcinoma at zoo Japan. Neither clinical respiratory nor circulatory symptoms caused by heartworm infection observed. The filarial worms identified as D. immitis from morphologic characteristics esophagus, presence faint longitudinal ridges on cuticular surface, situation vulva posterior to measurements body....
Few studies have been conducted on the presence of Salmonella in rodents that inhabit wet markets play an important role daily life Southeast Asia. The results as carriers vary greatly, ranging from absence to high prevalences. Previous investigated habitats such farms and urban wild areas where there is less rodent-human interaction than markets. Consequently, potential reservoirs transmitters great interest.Rodents were trapped eight traditional Thailand identified species level....
Abstract Background Paragonimus spp. (lung flukes) are among the most injurious foodborne helminths, infecting ∼23 million people and subjecting ∼292 to infection risk. Paragonimiasis is acquired from infected undercooked crustaceans primarily affects lungs but often causes lesions elsewhere including brain. The disease easily mistaken for tuberculosis owing similar pulmonary symptoms, accordingly, diagnostics in demand. Results We assembled, annotated, compared draft genomes of 4 prevalent...
Three hymenolepidid tapeworms, Hymenolepis diminuta , H. nana and microstoma are commonly maintained in laboratory rodents used many experimental model systems of tapeworm infections. We examined partial sequences from the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene nuclear ribosomal internal transcribed spacer 2 (ITS2) to infer phylogenetic relationships 3 species. Parts CO1 ITS2 were amplified by PCR sequenced directly. The sequence obtained was same length (391 bp) among all...
