title: [Invasiveness and developmental forms of 3 Babesia species and piroplasmids (Piroplasmida) in the eggs of ixodid ticks].
abstract: The paper presents the materials on the identification and study of the developmental forms and morphology of B. colchica and P. bigeminum in eggs of Hyalomma anatolicum. The description of developmental forms of B. colchica in eggs of Boophilus calcaratus is given for the first time. P. bigeminum and P. beliceri were detected in eggs of B. calcaratus and H. anatolicum from the first day of egg production up to the emergence of larvae while B. colchica was found beginning from the 4th-5th day of egg production up to the 5th-7th day before larvae emergence. The invasion rate of eggs of B. colchica is considerably smaller than that of B. bigeminum and P. beliceri. In piroplasmids and babesians there were observed sigar--like, roundish, amoebapear-, rod-shaped and oval forms. Some indivisuals of piroplasmids had projections of cytoplasm of different size. Individuals of B. colchica are smaller than those of P. bigeminum and P. beliceri that enables an easy differentiation of babesians from piroplasmids.
