COMPARATIVE ANALYSIS OF HEMATOLOGICAL, MICROMORPHOLOGICAL AND IMMUNOLOGICAL REACTIONS OF OBLIGATE AND NOT OBLIGATE DEFINITIVE HOSTS DIPHYLLOBOTHRIUM DENDRITICUM (CESTODA: PSEUDOPHYLLIDAE)
O.E. Mazоur, N.M. Pronin, A.S. Fomina, S.V. Pronina
The data on hematological, micromorphological and immunological reactions of obligate hosts (nestlings of herring gull) to cestode Diphyllobothrium dendriticum invasion in comparison with ones of unobligated hosts (syrian hamster, a cat) were analyzed. There were clear tendency to decreasing of hemoglobin level in blood of the infected herring gull’s nestlings. The tendency is partially compensated with the intensification of erythropoiesis in obligate hosts, and vice versa its depression in unobligated hosts. The cestode invasion activates Т-cell immune response and suppresses a B-cell response of unobligated hosts and activates lowly Т-and В-cell reactions of the obligate hosts.
Keywords: cestoda, Diphyllobothrium dendriticum, hematology, pathologic morphology, Т- and B-cell immune response.
