奶牛附红细胞体病感染途径(消化系统接种)的研究

12条健康幼犬．经血液学检查确认无附红细胞体感染后．随机分为对照组和消化道接种组，将奶牛附红细胞体阴性菌血和阳性菌血分别经呼吸道接种对照组和消化道接种组各犬，逐日采血，测定其红细胞感染率，并在红细胞感染率最高的时候，测定其生理指标、血液常规指标及血液生化指标。试验结果表明，消化系统接种组接种前后各犬体温、脉搏、呼吸、血红蛋白和一分钟胆红素无明显差异（P〉0．05）；红细胞感染率、红细胞总数、白细胞总数和总胆红素差异显著（P〈0．05），红细胞感染率最高可达30％。对照组没有明显变化。结果证明，消化道可以感染该病，为该病的预防和控制提供了重要的理论依据。

Studies on the Spread Approach (Infection Through Digestive System) in Eperythrozoonosis of Dairy Cow

The result showed that in the contrast group,erythro-cyte was free from Eperythrozoon and all of the index was normal,but in the digestive system infection group,there was no significant difference in temperature,pulse,breath frequency,serum hemoglobin,serum bilirubin in one minute,but the difference in leukocyte number,serum bilirubin,erythrocyte number was significant.Erythrocyte was infected by Eperythrozoon obviously,the highest erythrocyte infection rate approached 30%,It is proved that Eperythrozoonosis in dairy cow can transmit through digestive system.The important theoretical gist is given for the prevention and control to Eperythrozoonosis in dairy cow.
