本文报告在海南岛发现了斑点热疫源地，其人群北亚斑点热抗体的阳性率３８．３％，鼠类抗体阳性率５３．０％。从７种鼠检出抗体，其中优势种黄毛鼠（Ｒａｔｔｕｓｌｏｓｅａ）、黄胸鼠（Ｒ．ｆｌａｖｉｐｅｃｔｕｓ）和海南屋顶鼠（Ｒ．ｒａｔｔｕｓｈａｉｎａｎｉｃｕｓ）阳性率＞５０．０％，应用ＰＣＲ技术从该３种鼠检出斑点热群立克次体特异ＤＮＡ。小兽类寄生蜱３种、革螨５种，优势种分别为粒形硬蜱（Ｉｘｏｄｅｓｇｒａｎｕｌａｔｕｓ）和毒棘厉螨（Ｌａｅｌａｐｓｅｃｈｉｄｎｉｎｕｓ）；牛羊寄生蜱为微小牛蜱（Ｂｏｏｐｈｉｌｕｓｍｉｃｒｏｐｌｕｓ）。从粒形硬蜱和微小牛蜱检出斑点热群立克次体特异ＤＮＡ。
In this paper, we found spotted fever in Hainan Island. The positive rate of North Spot blotch antibody was 38.3% and the positive rate of mouse antibody was 53.0%. Antibodies were detected from seven kinds of mice. The positive rate of Rattuslosea, R. flavipectus and R.rattus hainanicus was> 50.0% Spotted fever group Rickettsia specific DNA. 3 species of small mammals and 5 kinds of leather mites. The dominant species are Ixodesgranulatus and Laelapsechidninus, respectively. The bovine and sheep ticks are Boophilus microplus. Spotted fever group Rickettsia specific DNA was detected from ticks and ticks.
