Paragonimosis is an important food-borne zoonosis especially in Asian countries. Among Paragonimus species, Paragonimus westermani followed by P. skrjabini complex are the major pathogens for human paragonimosis in Asia. In addition, P. heterotremus is an important pathogen in southern China and the Indochina Peninsula and is the only proven species to(More)
During an epidemiological survey for Paragonimus and paragonimosis in northern Vietnam, we found extremely large excysted metacercariae (2.50 ± 0.14 mm in length and 0.72 ± 0.08 mm in width; mean ± standard deviation of 20 samples) in mountainous crabs, Potamiscus mieni. Adult worms were successfully obtained by intraperitoneal injection with those large(More)
Based on morphology of metacercariae and adult worms together with molecular data from our previous study, we describe herein a new lung fluke species named Paragonimus vietnamensis sp. nov. Metacercariae of this new species is round and extremely large in size (nearly 800 μm in diameter) having a fragile outer cyst of variable thickness and a thin fragile(More)
The liquid by-product of the soybean product tofu, tofu whey (TW), was used as a growth medium for the production of Lactobacillus paracasei ssp. paracasei LG3 cultures. The TW used in this study contained stachyose, raffinose, sucrose, fructose and glucose, but the strain used could only utilize the three latter. The lactobacilli population obtained in MRS(More)
One hundredFrankia strains isolated from variousAlnus species in a single alder stand were tested for plasmid presence. Plasmid DNA was observed in five of the frankiae strains and was analyzed. We found that plasmids with a similar molecular weight exhibited in fact minor divergences in restriction patterns. The genetic diversity among the five isolates(More)
This study highlights data about the production of a recombinant protein (glyceraldehyde-3-phosphate dehydrogenase) byE. coli HB 101 (GAPDH) during batch and fed-batch fermentations in a complex medium. From a small number of experiments, this strain has been characterized in terms of protein production performance and glucose and acetate influences on(More)
A new water-soluble cerium-selective chromogenic azocalix[4]arene had been synthesized from diazo coupling reaction between calix[4]arene and diazonium salts, and characterized by HNMR, IR, UV and element analysis. It possesses a maximum absorbance at 365 nm in buffered aqueous environment, but addition of cerium(IV) ion induced a shift to 370 nm and a new(More)
