Matskási, I., Mészáros, F. , Murai, É.; Dudich, A.: On the parasite fauna of Microtus oeconomus Pallas, 1776 ssp. mehelyi Éhik, 1928 in Hungary (Trematoda, Cestoda, Nematoda, Siphonaptera)

5, Heligmosomum costellatum, which is one of the common nematodes of Microtus arvalis was only discovered in one case from M. oeconomus. 6, Heligmosomoides laevis had been still found with 32 per cent prevalence in the territory of Kis-Balaton LPA in 1964, but it has not occurred in the populations of Győr-Moson-Sopron. The present results, such as the above mentioned differences, suggest that further investigations are needed in order to solve this question. Table 1.
