The results indicated that Streptococcus in/ae was extremely sensitive to Calla Chinensis, Fructus Hippophae and Fructus Murne, highly sensitive to Sappan Lignum, Pericarpium Granati, Folium Eucalypti and Radix Scutellariae, moderately sensitive to Rh/zoma Coptidis, Radix et Rhizoma Rhei, Flos Caryophyllata, Cortex phellodendri and Rabdosia serra （ Maxim. ） Hara, and insensitive to Herba Portulacae , Herba Houttuyniae , Polygonum hydropiper L. , Herba Menthae , Radix Glycyrrhizae , Pericarpium Citri Reticulatae , Herba Andrographitis and Rhizoma Acori Tatarinowii. Chinese medicinal herbs which Streptococcus iniae was extremely sensitive or moderately sensitive to were selected and prepared into three Chinese herbal medicine formulae for medicated bath of Oreochromis niloticus infected arti- ficially with Streptococcus iniae. The results showed that medicated bath elicited therapeutic effects on infected Oreochromis niloticus. Formula II exhibited the best therapeutic effect with an effective percentage of 90%.展开更多

According to the results, multiple organs of infected foxes were congested and hemorrhaged with tissue damage, inflammatory cell infiltration and a series of pathological changes, mainly exhibiting hepatic cell cord rupture, liver cell granular degeneration and fatty degeneration, small intestinal mucous mem- brane shedding, intestinal villi necrosis and shedding, severe hemorrhage of lamina pmpria with inflammatory cell infiltration, and severe small intestinal bleeding. This study laid a solid foundation for clinical diagnosis, prevention and treatment of parvovirus infection in foxes.展开更多
