title: [Oesophagostomum quadrispinulatum (Marcone, 1901) Alicata, 1935--a new for Poland parasite of swine].
abstract: METHODS
  Large intestines of five slaughtered sows, aging 10 months to 3 years and originating from different herds of southern Poland, were examined parasitologically according to an agar-gel method. The intestines were uncoiled and divided into three sections: section 1--caecum and the first 0-20% part of colon, section 2-20--60% of large intestine and section 3--60-100% length of gut. Adult worms of Oesophagostomum were differentiated on the basis of species and sex, using the shape of buccal capsule and oesophagus, the length of male spicules, and the distance from vulva to anus as well as from anus to the tip of tail of females.
  
  
  RESULTS
  In the case of two sows, in 30% of the contents from the section 1 of large intestines a total of 10 specimens of Oesophagostomum quadrispinulatum (Marcone, 1901) Alicata, 1935 were found. This is a new nematode species in the parasitic fauna of Poland and the present record enlarges its geographical range. The infection with O. quadrispinulatum seems to be more dangerous from that of O. dentatum--the most common porcine nodular worm.
