摘要
本文报道从黑龙江省全沟硬蜱分离的伯氏疏螺旋体H7株的特征。H7株细胞长9.8—26.5μm,宽0.13—0.35μm,有1—11个波,波长1.2—3.0μm,波幅0.59—1.13μm,两端尖锐,每端有7根鞭毛,菌体左旋。体外培养最适温度为31℃,具有21k、32k、34k主要结构和抗原蛋白,能与新疆及黑龙江莱姆病人血清反应。这些结果表明,该菌株具备伯氏疏螺旋体的特征,它是与其它地区或媒介分离株不同的'亚型'。
We reported the detailed characteristics of Lyme disease spirochetes (Borrelia burgdorferi), strain H7, isolated from lxodes persulcatus in Heilongjiang. Cells of strain H7 were 9.8—26.5 μm long and 0.13—0.35 μm wide. There were 1—11 waves with a wavelength of 1.2—3.0 μm and an amplitude of 0.59—1.13 μm. Direction of spires was left. Seven flagella were inserted subterminally at each end of the cell and ends were pointed. 31℃ was the optimum cultural temperature in vitro. The major constitutional and antigenic proteins were 21k, 32k and 34k proteins. H7 could react on the patient sera of Xinjiang and Heilongjiang with IFA and western blot. These findings demonstrated that strain H7 belonged to species Borrclia burgdorferi, but was a new 'subtype' which differed from the strains isolated from other areas and vectors.
