Abstract

The interaction of intermediate host (Eogammarus tiuschovi) cells with the cysticercoid of Microsomacanthus lari of the cyclocercus type was examined for the case of damage of the noncellular exocyst surrounding it. Massive penetration of the host cells, supposedly haemocytes characterized by intensive secretion, into the exocyst was observed even during the first several minutes of the experiment. Large accumulations of the product of secretion (fibrous material) were concentrated in the distal areas of the endocyst glycocalix and the microvillar layer of the cysticercoid tail appendage. The results provide evidence for the defensive role of the exocyst of M. lari in the cellular response of an intermediate host organism to invasion.
