In the present study four different cell cultures, derived from rabbit kidney (RK13), rat, and murine liver (WBF344 and Hepa 1c1c7) and insect origin (Sf21) were used to examine the effects of chlorpyrifos. Sf21 cells were the most sensitive to chlorpyrifos, with significant suppression of their proliferative activity ranging from 10⁻¹-10⁻⁵ M. However, significant suppression of proliferative activity...
Summary SPF male Wistar rats were exposed for four months to lead acetate trihydrate present in drinking water (100 mg/l) and subsequently infested with 1000 ± 100 infective A. suum eggs. Metabolic activity of phagocytes and proliferative activity of T-lymphocytes were investigated on Day 4 and 8 after A. suum eggs infestation (Day 130 and 134 of lead acetate trihydrate exposition). The results demonstrated...
Coccidian oocysts were prevalent in nearly 100% of goats and sheep from various localities in Slovakia. In goats 4 Eimeria species were identified: E. ninakohlyakimovae (in kids 40%, in adult goats 51 %), E. arloingi (in kids 43%, in adult goats 20%), E. alijevi (in kids 12%, in adult goats 21 %) and E. hirci (in kids 3%, in adult goats 2%). In addition, 2-6% of coccidian oocysts were not speciated...
