摘要
The sera of 180 human samples were tested for the presence of antibodies against Borrelia burgdorferi using the ELISA （enzyme-linked immunosorbent assay） technique. Out of 180 sero-samples, 46 （25.55%） were positive. Females of the age range 18-35 years had the highest rate of sero-positive samples 14 （38.88%）, while the highest percentage of sero-negative samples was found in males of the age range 50-80 years. The other sero-positive samples were： 6 （26.08%）, 6 （25%） and 3 （11.53%） in males of ages between 18-35, 35-50 and 50-80 years, respectively, and 11 （29.72%） and 6 （17.64%） in females in the age ranges 35-50 and 50-80 years, respectively. The mean concentration of Anti- B. burgdorferi antibody was higher （16.7 U/mL） when compared with mean concentration of normal value （5.5 U/mL）, P 〈 0.001.
