摘要: Aim: The purpose of this pilot study was to genetically identify and characterize Coxiella burnetii from Amblyomma varigatum ticks collected on cattle in North central Nigeria. Materials Methods: A total 40 partially fed morphologically identified as adult A. variegatum owned by Fulani pastoralists were evaluated for the presence C. using PCR, cloning, sequencing heat shock polypeptide gene htpB. Results: DNA detected 10 (25%) analyzed. Sequences htpB our samples had 99-100% identity all other that have been described are deposited GenBank database. Phylogenetic analysis neighbor-joining method indicates clustering sequences areas with those Oyo state, South-western Nigeria Spain. Conclusion: This shows a high infection rate areas. inferences strain found states Plateau Nasarawa same previously reported South western state Oyo. pathogen naturally occurring tick populations could present an additional risk Q-fever disease humans, especially closely associated their animals easily exposed bites. Therefore, further studies needed assess competence vectors pathogens.
