title: [Structure and nutritional characteristics of the female Simondsia paradoxa (Nematoda, Spirurata)--a gastric parasite of swine].
abstract: Distinct dimorphism is inherent in the nematode Simondsia paradoxa. The male is small in size, its body is cylindrical which is typical of nematodes. The female is large with a very large spherical expansion in the middle part of the body. This difference in the female and male structure is due to their different localization. Male lives in the lumen of the stomach, female--in the thick stomach wall. The present paper gives the original morphological description of a female, besides some characteristics in the structure of this parasite have been revealed allowing the authors to outline the probable types of the parasite nutrition. The authors believe that along with digestive organs the covering tissues through which important substances enter the female body also take part in nutrition of the female.
