title: [Hereditary character of feature variability in Hymenolepis diminuta bred from oncospheres of defined origin].
abstract: Three groups of tapeworms obtained 2.5 month after the administration to rats of a dose of 6 cysticercoids proceeding from oncospheres of the 24th generation of Hymenolepis diminuta were compared. Group I came from the oncospheres of only one proglottid of H. diminuta WMS "strain" tapeworm. Group II proceeded from 6 proglottids obtained each from another tapeworm of this "strain". Group III came from 6 proglottids, each from another tapeworm of H. diminuta WMS inbred line 1 (il1). The average number of type 0p3a proglottids in group I and II was similar and amounted to 4.0% and 4.7%, respectively, while in group III it was significantly higher than in the first two groups and reached an average of 8.4% (P < 0.01). There are also other significant differences between the two breeding lines-H. diminuta WMS "strain" and WMS il1 with respect to the number of typical 1p2a proglottids, type 1p3a proglottids, the second after 0p3a most common deviation from the typical 1p2a as well as all deviations taken together. This points to the influence of different breeding condition: non-inbred in case of H. diminuta WMS "strain" and inbred in case of H. diminuta WMS il1 on the investigated features.
