The development of the piroplasm Babesia equi was studied by light microscopy in the gut and the haemolymph of three different Hyalomma species during and after the nymphs had engorged on parasitaemic horses. The stock of B. equi used was isolated from a horse imported from Turkmenistan (CIS) in 1991. The existence of gamogony was identified by the occurrence of gamonts and gametes in the gut contents of the nymphs at between 3 and 4 days after infestation of the nymphs, before the ticks dropped off the experimentally infected horses. Zygotes and kinetes were observed in the intestinal cells from day 4 until day 7 after infestation i.e. 2 days prior to engorgement until repletion of the nymphs. Simultaneously, kinetes could also be seen in the haemolymph of engorged nymphs. The morphology and the sequence of the developmental stages of B. equi identified in the gut and the haemolymph of the vector ticks were identical in all three Hyalomma species. They resembled typical developmental stages of bovine Theileria species. Because of the close similarity of the developmental cycle of B. equi in Hyalomma species to the life cycle of Theileria species and due to the differences to the other Babesia species, a discussion about classifying B. equi into the family of Theileriidae now seems to be justified.

Opisthorchiasis that is widely spreading in Russia and CIS countries was and remains a serious social, medical, and scientific problem. Local or imported cases of opisthorchiasis have been notified in 87.6% of the administrative territories of Russia. The world's largest focus of opisthorchiasis is the Ob-Irtysh river basin with natural preconditions for its high infection in fish. The main clinical manifestations of Opisthorchis infestation are associated with liver damage caused by the obligate presence of Opisthorchis in the bile capillaries with evolving cholangitis, cholangiocholecystitis, and cholangiopancreatitis. Opisthorchis complicates the course of many diseases, affecting gestation, labor, and postpartum. The state of thrombocytic and coagulation hemostasis was analyzed in different period of pregnancy and postpartum (days 2-4), by using the course of pregnancy in the inhabitants of the hyperendemic focus of Opisthorchis infestation (the Ob-Irtysh basin) as an example. In the newcomers, pregnancy develops in the presence of platelet hyperaggregation and accelerated continuous blood clotting. In pregnant women who belong to native little peoples (Khanty, Mansi), opisthorchiasis induces no significant changes in the hemostatic potential.
