Schistosoma malayensis n. sp.: A Schistosoma japonicum-Complex Schistosome from Peninsular Malaysia

Autochthonous Human Schistosomiasis, Malaysia

“…was described from intermediate snail ( Robertsiella sp.) and final mammalian hosts ( Rattus muelleri and R. tiomanicus [ 4 ]). S. malayensis is closely related to S. mekongi and differs genetically from the latter by ≈10%.…”

“…S. malayensis is closely related to S. mekongi and differs genetically from the latter by ≈10%. Both species differ from S. japonicum by 25% ( 5 ), and adult and ova morphologies are similar ( 4 ). Few transmission sites for this new S. japonicum –complex schistosome species were identified in rural areas ( 4 ).…”

“…Both species differ from S. japonicum by 25% ( 5 ), and adult and ova morphologies are similar ( 4 ). Few transmission sites for this new S. japonicum –complex schistosome species were identified in rural areas ( 4 ). We report after 30 years the histologic finding of S. malayensis –like eggs in the liver of a Malay man and discuss public health implications.…”

Relationships between Schistosoma malayensis and other Asian schistosomes deduced from DNA sequences

“…Most recently described is S. malayensis Greer, Ow-Yang and Yong, 1988 from a restricted area of peninsular Malaysia. This is primarily a parasite of rats but has also been found in people [2].…”

Schistosome Infections: An Indian Perspective

“…The conventional method of classifying these flukes was epidemiological and morphological characteristics like the geographical distribution, morphology of eggs and specificity and range of hosts [10]. S. malayensis primarily affect rat (Rattus muelleri) and is considered as a zoonotic disease [1,11,12]. Human infection infrequently occurs in Malaysian aboriginein foci of sylvatic transmission.…”
