| impact of temporal changes and host factors on the genetic structure of a population of opisthorchis viverrini sensu lato in khon kaen province (thailand). | the population genetics of 317 individual opisthorchis viverrini from khon kaen province thailand, from 4 different years and 4 cyprinid fish species was examined using multilocus enzyme electrophoresis of enolase (enol), phosphoglucomutase (pgm) and triose phosphate isomerase (tpi). allele and genotype frequencies for enol and pgm were consistent irrespective of year or host species. no heterozygote deficiency was detected for enol. significant heterozygote deficiencies were detected in 3 of 4 ... | 2009 | 19523258 |
| distribution and abundance of opisthorchis viverrini metacercariae in cyprinid fish in northeastern thailand. | to increase public health awareness for prevention of opisthorchiasis caused by eating raw freshwater fish, the distribution and abundance of opisthorchis viverrini metacercariae (ov mc) was investigated in freshwater fish obtained from 20 provinces in northeastern thailand between april 2011 and february 2012. a cross-sectional survey was conducted on 12,890 fish consisting of 13 species randomly caught from 26 rivers, 10 dams, and 38 ponds/lakes. fish, were collected in each of the rainy and w ... | 2013 | 24516277 |
| seasonal variation of opisthorchis viverrini infection in cyprinoid fish in north-east thailand: implications for parasite control and food safety. | reported is the seasonal pattern of opisthorchis viverrini metacercariae in cyprinoid fish in north-east thailand. samples of fish were collected in 1991-92 at monthly intervals from two areas-khon kaen province, where the opisthorchiasis transmission rate was high, and mahasarakham province, where the rate was low. metacercarial loads in both study areas had similar seasonal patterns. high burdens occurred in the late rainy season and winter (july to january) with low burdens during the summer ... | 1997 | 9185364 |
| a cross-sectional study on the potential transmission of the carcinogenic liver fluke opisthorchis viverrini and other fishborne zoonotic trematodes by aquaculture fish. | throughout southeast asia and china, eating raw and or partially cooked cyprinid fish causes liver (hepatobiliary) disease and cancer (cholangiocarcinoma) due to fishborne zoonotic trematodes (fzt), in particular clonorchis sinensis and opisthorchis viverrini. the primary source of transmission is by native fish, but aquaculture fish are also reported to have high infective potential. here, a cross-sectional survey of fzt in fish farms was conducted in an endemic area in khon kaen province, thai ... | 2013 | 23320421 |
