hepatosplenic lesions induced by experimental schistosoma malayensis in rabbits.two groups of three rabbits each were infected with 250 cercariae of the baling and koyan strain of schistosoma malayensis. changes induced by both strains included periportal hepatocellular necrosis and fibrosis. vascular changes such as portal phlebitis and thrombophlebitis and varying degrees of pericholangitis were also present. amyloid deposition was noted. a comparative study of the changes induced in rabbits by s. malayensis, s. mekongi and s. japonicum showed that the hepatic lesions ind ...19938266238

making the most of mitochondrial genomes--markers for phylogeny, molecular ecology and barcodes in schistosoma (platyhelminthes: digenea).an increasing number of complete sequences of mitochondrial (mt) genomes provides the opportunity to optimise the choice of molecular markers for phylogenetic and ecological studies. this is particularly the case where mt genomes from closely related taxa have been sequenced; e.g., within schistosoma. these blood flukes include species that are the causative agents of schistosomiasis, where there has been a need to optimise markers for species and strain recognition. for many phylogenetic and po ...200717570370
schistosomiasis malayensis-like infection among the penan and other interior tribes (orang ulu) in upper rejang river basin sarawak malaysia.a serosurvey of various indigenous interior tribes (orang ulu) in upper rejang river basin sarawak malaysia, the site of a multibillion ringgit hydroelectric power project, found 6.8% of the individual surveyed were seropositive for schistosomiasis, as determined by elisa method using the soluble egg antigen of schistosoma malayensis baling strain. in all age group, the seroprevalence rate is higher (9.5%) in males than in females (4.5%) except for the 31-40 age group. seroprevalence of schistos ...200111485090
pulmonary pathology in rabbits infected with the baling and koyan strains of schistosoma malayensis.two distinct strains of schistosoma malayensis exist in malaysia (designated the baling and koyan strains). both these strains show intraspecific variations in pathology (greer et al, 1988). to evaluate the differences in the pulmonary pathology resulting from infections of the two different strains of malaysian schistosome, a total of 20 experimental rabbits were infected, 10 each with cercariae of the koyan strains. pathological changes were studied over a period of 28 weeks. granulomas in the ...19921298078
induction of intestinal lesions in rabbits with koyan and baling strains of schistosoma malayensis sp n.schistosoma malayensis sp n is a putative new species of schistosome discovered in peninsular malaysia in 1973. this paper comprises the first report on the detailed gastrointestinal pathology present in rabbits infected with strains of the parasite. two different strains of schistosome--the baling and koyan strains--from two different ecosystems were used to infect inbred rabbits and the resulting pathophysiology was studied. our results showed that the baling strain of s. malayensis was more v ...19921523486
schistosoma malayensis n. sp.: a schistosoma japonicum-complex schistosome from peninsular malaysia.schistosoma malayensis n. sp., a member of the schistosoma japonicum complex is described from rattus muelleri in peninsular malaysia and 2 strains are characterized. the only morphological differences noted among adults from natural hosts were that s. malayensis are in general smaller than s. mekongi and s. japonicum. but these differences may be the result of host-induced variations and therefore are of little taxonomic value. to minimize the effects of host-induced variations, adult worms rec ...19883379527
malaysian schistosomiasis: description of a population at risk.a stable population at risk of malaysian schistosomiasis was studied. census results indicated that approximately one-fourth of the inhabitants used a stream where schistosoma malayensis-infected snails were present as their principal source of water for bathing, drinking, and household tasks. the general population also contacted this stream when fording it or while fishing. serological surveys using enzyme-linked immunosorbent assay (elisa) and the circumoval precipitin (cop) test revealed six ...19892738992

codon usage and bias in mitochondrial genomes of parasitic platyhelminthes.sequences of the complete protein-coding portions of the mitochondrial (mt) genome were analysed for 6 species of cestodes (including hydatid tapeworms and the pork tapeworm) and 5 species of trematodes (blood flukes and liver- and lung-flukes). a near-complete sequence was also available for an additional trematode (the blood fluke schistosoma malayensis). all of these parasites belong to a large flatworm taxon named the neodermata. considerable variation was found in the base composition of th ...200415591833
