| [intestinal flukes of genus metagonimus and their second intermediate hosts in kangwon-do]. | this study investigate the epidemiological feature of metagonimus infection in kangwon-do (province). the average infection rate of the surveyed inhabitants was 7.8% (83 positives out of 1, 067 examinees) by stool examination; male, 11.4% and female, 3.2%, respectively. the egg positive rate in residents in the som river area was 7.3%, that of the chuchon river area 6.3%, the pyongchang river area 12.8%, the tong river area 3.8%, the hongchon river area 9.8%, and the ohsip stream area of samchok ... | 1993 | 8297890 |
| classification and host specificity of metagonimus spp. from korean freshwater fish. | taxonomic problems of metagonimus spp. in korea were investigated. metacercariae of various freshwater fish species -- plecoglossus altivelis, carassius auratus, zacco platypus, zacco temmincki, opsariichthys bidens -- were collected from different localities in korea and experimentally fed to golden hamsters. observation of recovered adult worms showed that plecoglossus altivelis was infected with metacercariae of both m. yokogawai and m. takahashii. c. auratus was infected with metacercariae o ... | 1996 | 8820736 |
| mitochondrial diversity of opsariichthys bidens (teleostei, cyprinidae) in three chinese drainages. | we describe the phylogeographic structure of 28 chinese populations of the cyprinid opsariichthys bidens across three main chinese river drainages. our study is based on the phylogenetic analysis of the complete mitochondrial cytochrome b gene (1140 bp). we combined this analysis with population processes inferred from nested clade analysis (nca) and mismatch distributions. both analyses showed that chinese o. bidens consists of five mtdna lineages (opsariichthys 1-5) with high genetic divergenc ... | 2005 | 15964769 |
| population dynamics and maturation cycle of camallanus cotti (nematoda: camallanidae) in the chinese hooksnout carp opsariichthys bidens (osteichthyes: cyprinidae) from a reservoir in china. | the seasonal population dynamics and maturation cycle of the nematode camallanus cotti in the posterior intestine of chinese hooksnout carp opsariichthys bidens have been studied in the danjiangkou reservoir of the hubei province in central china from september 2004 to november 2005. the overall prevalence, mean abundance and intensity of c. cotti among fish sampled (n=700 fish) were 47%, 2.29+/-12.38 (+/-s.d.) and 1-307 (average 4.89+/-17.74), respectively. the overall sexual ratio of female to ... | 2007 | 17459589 |
| inverse pcr-based method for isolating novel sines from genome. | short interspersed elements (sines) are moderately repetitive dna sequences in eukaryotic genomes. although eukaryotic genomes contain numerous sines copy, it is very difficult and laborious to isolate and identify them by the reported methods. in this study, the inverse pcr was successfully applied to isolate sines from opsariichthys bidens genome in eastern asian cyprinid. a group of sines derived from trna(ala) molecular had been identified, which were named opsar according to opsariichthys. ... | 2014 | 24122282 |
| habitat-specific locomotor variation among chinese hook snout carp (opsariichthys bidens) along a river. | the wujiang river is a tributary of the upper yangtze river that shows great variations in its flow regime and habitat condition. dams have been built along the wujiang river and have altered the habitats profoundly enough that they may give rise to reproductive isolation. to test whether the swimming performance and morphology of the chinese hook snout carp (opsariichthys bidens), varied among habitats and whether the possible differences had a genetic basis, we measured the steady and unsteady ... | 2012 | 22829884 |
| the complete mitochondrial genome of the chinese hook snout carp opsariichthys bidens (actinopterygii: cypriniformes) and an alternative pattern of mitogenomic evolution in vertebrate. | the complete mitochondrial genome sequence of the chinese hook snout carp, opsariichthys bidens, was newly determined using the long and accurate polymerase chain reaction method. the 16,611-nucleotide mitogenome contains 13 protein-coding genes, two rrna genes (12s, 16s), 22 trna genes, and a noncoding control region. we use these data and homologous sequence data from multiple other ostariophysan fishes in a phylogenetic evaluation to test hypothesis pertaining to codon usage pattern of o. bid ... | 2007 | 17587513 |
