Morphological observation on the reproductive system of adult Schistosoma japonicum under an optical microscope / 中国血吸虫病防治杂志

ABSTRACT

Objective To investigate the morphological features of reproductive system of adult Schistosoma japonicum under an optical microscope.Methods Adult schistosomes were obtained from infected mice with cercariae shedding from Oncomelania snails.The adult worms fixed with 10% formalin,dehydrated,imbedded in paraffin,cut at 3 ?m thick,stained by HE staining and then observed under an optical microscope.Results The reproductive organs of adult Schistosoma japonicum such as testicle,ovary,fallopian tube,vitellarium,yolk duct and hystera were displayed distinctly and typically.Conclusions The morphological features of reproductive system of adult Schistosoma japonicum are distinct and typical by using routine pathological techniques preparing and HE staining,which establishes a morphological foundation for the morphological teaching of schistosomes and reproductive biology research.
