奶牛附红细胞体幼犬消化系统人工感染研究

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。本试验结果表明,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。试验结果表明,消化道可以感染该病。

Studies on the spread approach (infection through digestive system) in eperythrozoonosis of dairy cow

Twelve young healthy dogs,which were free from Eperythrozoon by blood test,were divided into two groups randomly.One was control group which was inoculated negative blood(normal dairy cow blood).The other was digestive system infection group which was inoculated positive blood(dairy cow blood infected from Eperythrozoon) through digestive system.The infection rate of erythrocyte was measured every day,and the physiology index,blood rut and blood biochemical index were measured at the summit of erythrocyte infection rate.The result showed that in the control group,erythrocyte 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 was given for the prevention and control to Eperythrozoonosis in dairy cow.
