Abstract:
... Genetic variation in Opisthorchis viverrini adults originating from different locations in northeast Thailand and Laos, People’s Democratic Republic (PDR), was examined using random amplified polymorphic DNA (RAPD) analyses. In an initial analysis, the genomic DNA of one fluke from each of ten localities was amplified using 15 random primers (10-mers); however, genetic variation among O. viverrini ...

Abstract:
... Focus groups (n =65) were conducted with Hmong adults in St. Paul/Minneapolis, MN to determine how environmental factors, acculturation, and food insecurity influence dietary behavior, body mass index (BMI), and health. Acculturation was assessed by examining linguistic, social, and eating behavior, length of time in the US, and BMI for B-TL¹ (born in Thailand/Laos and in US <=5 years), B-TL² (in ...

Both species were also recently found in China and Lao People's Democratic Republic (PDR). Those two Paragonimus spp. are distinguishable from each other by morphological features of metacercariae and adults. However, recently, the DNA sequences ...
