山东省附红细胞体病的流行病学调查

目的了解山东省附红细胞体(附红体)的感染情况.方法用血涂片、镜检的方法检测山东省7个地区的不同人群776人,家畜198只,野鼠114只.结果全省人群附红体总感染率为7.3%,不同地区的感染率差异有非常显著性(P＜0.01).比较男女两组之间的感染率差异无显著性(x2=0.436,P＞0.05).年龄组比较,青壮年感染率明显高于少年组和老年组(P＜0.05).在各种职业人群中,屠宰工的附红体感染率明显高于农民、小学生及城镇居民(P＜0.01).附红体感染率与人体健康状况有关,患有肝炎、糖尿病、关节炎等慢性疾病的人群感染率显著高于正常人群(X2=4.375,P＜0.05).羊的附红体感染率为15.6%,牛的感染率为3.2%,鼠的感染率为零.感染强度大部分为低度.结论首次证明山东省人畜间广泛存在附红体感染.

An epidemic investigation of eperythrozoonsis in Shandong province

Objective To learn the status of infection of eperythrozoonsis in Shandong province. Methods Seven hundred and seventy six human blood samples, 198 domestic animal blood samples and 114 wild rat blood samples were collected. Eperythrozoon was detected in the human and animal blood stain slides under microscope. Results Overall infection rate of Eperythrozoon in human population was 7.3 %. Rates were significantly different ( P < 0.01 ) in different districts but no significant difference was found between men and women ( P > 0.05 ). The rate among adults was higher than that of teenagers and elderly. It was also noticed that the rates of people affected with chronic diseases as hepatitis, diabetes and arthritis were higher than those without. The infection rates of goat, cows and rats were 15.6 %, 3.2 % and 0, respectively. Conclusion Data showed that Eperythrozoon infection was intensively identified in the people and animals in Shandong province.
