HLA-typing in Schistosoma japonicum infection

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1988
Abstract : HLA-typing was recently performed on 41 schistosomiasis patients and 25 uninfected Filipino controls to investigate why patients have either cerebral or hepatic involvement. Neither the following tests HLA-B16, HLA-B40, nor other HLA-typing were significantly frequent in patients with cerebral schistosomiasis.

Schistosoma japonicum infection in pregnant mice

Journal of Helminthology, 1999
Ten 1-week and ten 2-weeks pregnant female NMRI mice were experimentally exposed to 70 Schistosoma japonicum cercariae. Ten littermice from each group were examined for worms by perfusion 4, 6 and 8 weeks post infection. Although the mothers (n = 15) were found infected with 15.5 ± 13.4 worms at perfusion 6 and 7 weeks post infection, no worms were ...

Schistosoma japonicum: A method for transformation by electroporation

Experimental Parasitology, 2005
Despite of our knowledge of genetic make up of schistosomes, a number of genes have not been characterized largely due to lack of effective transformation protocols. Here we present electroporation as a strategy for effective introduction of plasmids DNA into schistosomula and adults.

Nutritional Requirements of Schistosoma japonicum Eggs

The Journal of Parasitology, 1983
Newly laid eggs of Schistosoma japonicum were cultured in a serum-free, chemically defined medium, RPMI 1640, which contained 20 amino acids, glutathione, 11 vitamins, and glucose in a balanced salt solution. The requirements for these components in the nutrition of the eggs was investigated by the deletion of single component from the medium.

Host Identification by Schistosoma japonicum Cercariae

The Journal of Parasitology, 1987
Attachment, the first phase of host identification by Schistosoma japonicum cercariae, can occur in 2 different ways. Cercariae clinging to the water surface simply swing around and transfer to the host skin. Free-swimming cercariae behave like S. mansoni: upon touching a substrate, they switch from tailward to forward movement, swim in an arc, and ...

Congenital transmission of Schistosoma japonicum in pigs.

The American journal of tropical medicine and hygiene, 1999
Congenital transmission of Schistosoma japonicum in pigs was investigated by experimentally infecting sows at four weeks gestation (n = 3), 10 weeks gestation (n = 3), or a few weeks prior to insemination (n = 2). None of the piglets born to sows infected prior to insemination or in early pregnancy were found to be infected. However, all of the piglets

Identification of long noncoding RNAs in Schistosoma mansoni and Schistosoma japonicum

Experimental Parasitology, 2018
Schistosomiasis is a major parasitic disease caused by 3 principal species of schistosome. Studies of schistosome transcriptomes have focused on protein-coding transcripts and although miRNAs are attracting increased attention, few reports have concerned the long noncoding RNAs (lncRNAs).

Congenital transmission of Schistosoma japonicum in the rabbit

Journal of Helminthology, 2000
AbstractFourteen pregnant rabbits were each infected with 300 cercariae of Schistosoma japonicum and divided into two groups. Group M (n = 8) was infected during mid-gestation (the organogenetic stage) and group L (n = 6) was infected during late-gestation (the post-organogenetic stage).

Pathogenesis of Congenital Infection with Schistosoma japonicum in Pigs

The Journal of Parasitology, 2002
To elucidate aspects of pathogenesis of congenital infections with Schistosoma japonicum, 5 Danish crossbred sows were infected during late pregnancy with a Chinese isolate of S. japonicum, and 17 of their offspring (fetuses and piglets) were examined 7, 20. 34, 54, and 69 days postinfection (PI).

In vivo Labeling of Schistosoma japonicum Cercariae with 35 S

The Journal of Parasitology, 1997
A technique was developed for in vivo labeling of adult Schistosoma japonicum worms using 35S bound to methionine and cysteine. The isotope was applied in an in vivo labeling system in which Oncomelania hupensis snails harboring a patent S. japonicum were individually exposed to the label. Following exposure to cercariae, mice were perfused after 6 wk.
