目的　对粤东地区的自然人群、动物宿主和传播媒介进行调查研究，以证实该地区莱姆病疫源地的存在。方法　选取粤东梅州市的梅县梅南林场、大埔县丰溪林场和平远县木溪管理区为调查点，用间接免疫荧光抗体试验(IFA)和间接酶联免疫吸附试验(ELISA)进行人群和宿主动物的血清学调查，个案流行病学调查，动物宿主和媒介生物的病原学调查。结果　从检测2184份自然人群的血清得知，该地区人群莱姆病感染率为10.30％，林区(10.37％)与非林区(10.27％)人群感染率差异无显著性(x2=0.21，P>0.5)。检测牛和野鼠类动物血清各30份，感染率分别为23.33％和43.33％，并从褐家鼠和白腹巨鼠分离到2株莱姆病螺旋体，因此，我们认为鼠类和牛可能是当地莱姆病螺旋体的重要动物宿主。检查蜱506只，台湾角血蜱为优势种(97.43％)，台湾角血蜱中肠带莱姆病螺旋体率为16.00％(8／50)，并分离出1株莱姆病螺旋体，可见台湾角血蜱是当地莱姆病螺旋体主要生物媒介。结果　首次确认粤东地区为我国莱姆病的一个自然疫源地。

Aim To investigate the natural population, animal hosts and transmittions vectos of Lyme disease in Mei-nan Forestry Centre & Da-pu. Ping-yuan Counties. Mei-zhou city Guangdong province. Methods Using IFA. ELISA.& individual case studies on human and animal hosts etiological studies of the transmittions vectors.Results 2 184 naturally populated human sera were detected for, infective rate of Lymw disease was 10.30%, in forest area the rate was 10.37% .wheras no-forest area, 10.27% .There were no apparent difference in the infective rates of human infections between the two aress ( X2 = 0.21, P >0.5). There were 60 animal sera examined from cattle and rats (each 30), the infective rates found were 23.33% and 43.33%. respecti Borrelia burgdorferi was revealled in the bodies of Rattus norvegicus and R. Edwardsi vely respectivey. Consequently, rats and cattle might be considered two important animal hosts of Borrelia burgdorferi.There were 506 ticks examined. Haemaphysalis cornigera taiwana was found to be the prominent species (97.43%) collcted. The infective rate of Borrelia burgdorferiwas 16.00% (8/50) in the gut of Haemaphysalis cornigera taiwana. Borrelia burgdorferiwere recovered from the ticks. Haemaphysalis cornigera taiwan was the main trasmittion vector of Lyme disease in the area. Conclusion In this report we presented evidences showing that the area of eastern part of Guangdong province, including Mei-nan Forestry Centre and fumxi Foresty Centre of Da-pu county. Mu-xi of Ping-yuan County, Mei-zhou city, is a natural focus of Lyme disease in China.
