【 摘 要 】

ABSTRACT: The activation of carp peripheral blood leukocytes (PBL) was analysed radiometrically and by means of flow cytometry (FCM) in order to compare the results obtained with both methods. The qualitative and quantitative FCM analyses of cellularmorphology and viability resulted in a further characterisation of proliferative responses of carp PBL to Trypanoplasma borreli in vivo and in vitro. The lymphocyte population of PBL from T. borreli-infected carp exhibited amarked shift in forward scattered light (FSC; cell size). When PBL from healthy carp were stimulated with mitogens in vitro, a lymphoid population with increased FSC profiles was also observed. The number of these cells coincided to ratios of³H-thymidine incorporation, recorded from corresponding cultures. Thus, it was concluded that the increase in size of stimulated lymphocytes could be due to blastogenic transformation. The advantage of the FCM procedure is that activation andproliferation of carp lymphocytes can be monitored without labelling the cells. Cocultures of mitogen-stimulated carp PBL and T. borreli revealed the ability of the parasite to suppress lymphocyte proliferation in vitro.
