BACKGROUND Polyparasitism can lead to severe disability in endemic populations. Yet, the association between soil-transmitted helminth (STH) and the cumulative incidence of Schistosoma japonicum infection has not been described. The aim of this work was to quantify the effect of misclassification error, which occurs when less than 100% accurate tests are used, in STH and S. japonicum infection ...
Transposons Tn501 (specifying mercury resistance) and Tn7 (specifying resistance to trimethoprim and streptomycin) were introduced into extra-slow-growing Rhizobium japonicum by conjugal transfer of the 82 kilobase chimeric plasmid pUW942. Mercury-resistant transconjugants were obtained at a frequency of 10 to 10. The transfer frequency of streptomycin resistance was lower than that of mercury ...
BACKGROUND Schistosomiasis remains a major public health concern affecting billions of people around the world. Currently, praziquantel is the only drug of choice for treatment of human schistosomiasis. The emergence of drug resistance to praziquantel in schistosomes makes the development of novel drugs an urgent task. Thioredoxin glutathione reductase (TGR) enzymes in Schistosoma mansoni and s...
The symbiotic potential of Bradyrhizobium japonicum isolates indigenous to seven Korean soils was evaluated by inoculating soybeans with 10- and 1,000-fold-diluted soil suspensions (whole-soil inocula). At both levels, significant differences in the symbiotic potential of the indigenous B. japonicum isolates were demonstrated. The relationship between rhizobial numbers in the whole-soil inocula...
We describe the design and report baseline results of a cluster-randomized intervention to determine the importance of bovines for Schistosoma japonicum transmission in southern China. The study involves four matched village pairs in Hunan and Jiangxi Provinces, with a village within each pair randomly selected as intervention (human and bovine praziquantel treatment) or control (human praziqua...
BACKGROUND/OBJECTIVES In this study, the inhibitory effect of Erythronium japonicum extracts on the metastasis of MDA-MB-231 human breast cancer cell line was determined. MATERIALS/METHODS Cells were cultured with DMSO or with 50, 75, 100 or 250 µg/ml of Erythronium japonicum methanol or ethanol extract. RESULTS Both methanol and ethanol extracts significantly inhibited the growth and induc...
El objetivo del presente trabajo fue evaluar el efecto de bioproductos en crecimiento, producción y estado fitosanitario plantas nabo, teniendo cuenta la viabilidad uso quitosano e inoculantes elaborados a partir cepas Bradyrhizobium japonicum, para contribuir con prácticas más sostenible este cultivo. La investigación realizada campus “La María” Universidad Técnica Estatal Quevedo, provincia l...
Bacteriocin-like substances were commonly produced by slow-growing Rhizobium japonicum and cowpea rhizobia on an L-arabinose medium. Antagonism between strains of R. japonicum was not detected in vitro; however, such strains were often sensitive to some bacteriocins produced by cowpea rhizobia. Inhibitory zones (2 to 8 mm from colony margins), produced by 58 of 66 R. japonicum test strains, wer...
Eight geographical isolates of Schistosoma japonicum from Taiwan and mainland China and one isolate of Schistosoma mansoni were studied by RAPD analysis using six arbitrary primers and SSR-PCR analysis using a (CA)8RY primer. The genetic distance was determined by the percentage of unshared bands. The RAPD and SSR-PCR results showed that the genetic distance between S. mansoni and S. japonicum ...
BACKGROUND Schistosoma japonicum is a major public health concern in China, with over one million people infected and another 40 million living in areas at risk of infection. Unlike the disease caused by S. mansoni and S. haematobium, schistosomiasis japonica is a zoonosis, involving a number of different mammalian species as reservoir hosts. As a result of a number of published reports from Ch...
