摘要:

目的 检测长角血蜱中汉赛巴尔通体的携带情况。方法 将采获于石家庄市灵寿县的长角血蜱分组,经无菌处理后研磨匀浆,一部分直接提取DNA进行PCR检测,另一部分接种于含5%去纤维羊血的胰酶大豆培养基上,在37 ℃,5%CO2的培养箱中进行培养后,挑取疑似菌落进行PCR检测。对所得阳性条带的PCR产物测序,并将所测核酸序列在GenBank中进行序列比对。结果 菌落提取的DNA样品中有2个样品出现阳性条带,但测序未得结果;直接提取的DNA样品中有1个样品出现阳性条带,经过同源性比对后为汉赛巴尔通体。结论 石家庄市灵寿县采集到的长角血蜱中存在汉赛巴尔通体感染,这是首次在长角血蜱中检测到汉赛巴尔通体。

Abstract:

Objective To detect the infection with Bartonella henselae in Haemaphysalis longicornis. Methods Haemaphysalis longicornis captured in Lingshou county, Shijiazhuang, Hebei province, China, were divided into groups. The H. longicornis in each group was disinfected, sterilized, and grinded. Half of the grinded mixture was directly used for DNA extraction and polymerase chain reaction (PCR) analysis;the other half was inoculated onto tryptic soy agar supplemented with 5% defibrinated sheep blood followed by culturing in a 5% CO2 incubator at 37 ℃, and the suspected colonies were selected for PCR analysis. The PCR products that produced positive bands were sequenced, and the nucleotide sequences obtained were aligned with known sequences in GenBank. Results A positive band was observed in one sample from direct DNA extraction, the sequence of which was found to belong to B. henselae by alignment analysis. Positive bands were observed in two DNA samples isolated from bacterial cultures, but no results were produced from sequencing. Conclusion Haemaphysalis longicornis collected in Lingshou county, Shijiazhuang, are infected with B. henselae. This is the first detection of B. henselae infection in H. longicornis.

Key words: Haemaphysalis longicornis, Bartonella henselae, Culture, Polymerase chain reaction
