Abstract
This work is presenting the capacity of spontaneous leucocite blastization in sheep from Romney March and Ţigaie breed infestated with L. sericata larvae comparatively with non-infestated sheep. The experiment was realized on 24 sheep, first group of 12 Romney March and the second group of 12 Ţigaie with experimentally induced blowfly. From the two groups, blood samples were collected in days 0, 7 and 14 post-infestation, performing blastical transforming test – integral blood option. L.sericata infestation determined a increase of the leucocites spontaneous blastization to the infested groups. Blastization stimulation values were mostly negative. Blastization stimulation index were mostly of negative values. PHA or L.sericata antigen blastogenesis stimulation in various doses had similar effect, for non-infested groups observing a decrease of the stimulating index 7 days from disease debut and an increase at the end of the experiment
