Neospora caninum is an intracellular apicomplexan parasite that infects a wide range of mammals and has been associated with abortion in cattle worldwide. Artemisinin is an effective antimalarial compound derived from a traditional Chinese herbal remedy, qinghao or Artemisia annua L. In the study reported, the cultured host cells (vero cells or mouse peritoneal macrophages) infected with N. caninum tachyzoites were incubated with alpha-MEM (minimal essential medium) 10%HS supplemented with various concentration or artemisinin (20, 10, 1, 0.1 and 0.01 microg/ml) to examine the efficacy of artemisinin against N. caninum tachyzoites intracellular multiplication. In long-term studies, at 20 or 10 microg/ml for 11 days, artemisinin reduced N. caninum and completely eliminated all microscopic foci of N. caninum. At 1 microg/ml for 14 days, artemisinin reduced N. caninum and completely achieved elimination of all microscopic foci of N. caninum. There was no apparent toxicity to host cells in long-term studies. In short-term studies, at > or = 0.1microg/ml, artemisinin reduced N. caninum tachyzoites intracellular multiplication, significantly (P < 0.05) and appeared to depend on the artemisinin concentrations. Pretreatment of host cells or N. caninum tachyzoites with artemisinin had no effect on N. caninum tachyzoites intracellular multiplication. These results demonstrate that artemisinin inhibited N. caninum tachyzoites intracellular multiplication. 相似文献

This study aimed to analyze the economic effect of the red sea bream Pagrus major offshore aquaculture production system in Korea. Based on the data collected, revenue and expenses throughout the culture period were calculated, and the net present value and internal rate of return of the ten-year cash flow and cash outflow were estimated in order to determine the economic validity of red sea bream offshore aquaculture production. Results showed that the red sea bream offshore aquaculture production system had high profitability based on the current production and market conditions. This is because of its relatively high survival rate, relatively low feed conversion ratio, and good market price level. However, sensitivity analyses of the main variables indicated that the profitability of red sea bream offshore aquaculture is highly vulnerable to production conditions and market condition changes. 相似文献
