BACKGROUND Human schistosomiasis is one of the most prevalent and serious parasitic diseases worldwide. Schistosoma japonicum is one of important pathogens of this disease. MicroRNAs (miRNAs) are a large group of non-coding RNAs that play important roles in regulating gene expression and protein translation in animals. Genome-wide identification of miRNAs in a given organism is a critical step ...

There are few cases of prostatic schistosomiasis. Here we report a case of Schistosoma japonicum of the prostate, in which the immunophenotyping of individual glandular tubes was atypical. Whether the S. japonicum infection contributed to the lesion or not is unknown. We suspect the lesion was a sign of early precancerous hyperplasia. Follow-up of this patient may give clues about the relations...

Schistosomiasis is a major human parasitic disease with a global impact. Schistosoma japonicum, the most difficult to control, can survive within host veins for decades. Mechanisms of immune evasion by the parasite, including antigenic variation and surface masking, have been implicated but not well defined. In this study, we defined the immunoglobulin-binding proteomes of S. japonicum using hu...

Soybean lectin (SBL) purified from soybean seeds by affinity chromatography strongly bound to Bradyrhizobium japonicum USDA 110 cell surface. This lectin enhanced biofilm formation by B. japonicum in a concentration-dependent manner. Presence of galactose during biofilm formation had different effects in the presence or absence of SBL. Biofilms were completely inhibited in the presence of both ...

A glyceollin I accumulation o f about 6000 pmol • mg dry weight, a tenfold increase above control root tissue, was found in one type o f nodule from Glycine max which had been infected with a fix~ strain (61-A-24) o f Rhizobium japonicum. In nodules infected with one other ineffective (ßx~) strain o f Rhizobium japonicum (RH 31-Marburg) or with two f i x + strains o f Rhizobium japonicum (61 -A...

Bradyrhizobium japonicum is a facultative chemolithoautotroph capable of using thiosulfate and H(2) as an electron donor and CO(2) as a carbon source. In B. japonicum USDA110, the mutant of cbbL gene encoding a large subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) was unable to grow using thiosulfate and H(2) as an electron donor. The cbbL deletion mutant was able to grow a...

Biogenesis of c-type cytochromes in alpha- and gamma-proteobacteria requires the function of a set of orthologous genes (ccm genes) that encode specific maturation factors. The Escherichia coli CcmE protein is a periplasmic heme chaperone. The membrane protein CcmC is required for loading CcmE with heme. By expressing CcmE (CycJ) from Bradyrhizobium japonicum in E. coli we demonstrated that hem...

BACKGROUND Schistosomiasis remains a major public health problem in China. The major endemic areas are located in the lake and marshland regions of southern China, particularly in areas along the middle and low reach of the Yangtze River. Spatial analytical techniques are often used in epidemiology to identify spatial clusters in disease regions. This study assesses the spatial distribution of ...

Following Schistosoma japonicum (S. japonicum) infection, granulomatous responses are induced by parasite eggs trapped in host organs, particular in the liver, during the acute stage of disease. While excessive liver granulomatous responses can lead to more severe fibrosis and circulatory impairment in chronically infected host. However, the exact mechanism of hepatic granuloma formation has re...

background: trematodes belonging to the genus schistosoma cause schistosomiasis. the relationship between schistosomes and their intermediate hosts varies among snails. this study investigated the effects of s. japonicum on its snail host, oncomelania hupensis, and cercarial release rythmicity of s. japonicum and the effects of light on it. methods: : seven groups of o. hupensis (n = 40 each) w...
