The spectrum of intestinal parasites present in the Swiss
Webster, C57B1/6 and DBA/2 mice strains from different
animal houses was identified and prevalences compared.
Three parasites were observed during the course of this
study, namely the cestode Vampirolepis nana
(Siebold, 1852) Spasskii, 1954 (= Hymenolepis
nana) and the nematodes Aspiculuris tetraptera
(Nitzsch, 1821) Schulz, 1924 and Syphacia obvelata
(Rudolphi, 1802) Seurat, 1916.
The scope of this investigation has been widened to also
include morphometric data on the parasites, to further
simplify their identification, since the presence of
helminths in laboratory animals is regarded as a
restricting factor for the proper attainment of
experimental protocols.
