en Microbial pathogenesis Microbial pathogenesis Case Report Case Report Ticks harbor many pathogenic, as well as endosymbiotic and non-pathogenic agents. They are host of a variety of as yet unidentified microbes that continue to be described. In the present study, a<em> Brucella</em>-like<em> bacterium</em> was detected in a <em>Boophilus </em>tick by PCR amplification of a partial fragment of 16S rRNA locus followed sequencing. Our results show that the members of the genus <em>Boophilus</em> may act as vectors of brucellosis in nature, but further studies are required to confirm the real role of ticks as vector or reservoirs of specific <em>Brucella</em> species. 16S rRNA, phylogenetic tree, Brucellaceae, Boophilus 66 68 http://jommid.pasteur.ac.ir/browse.php?a_code=A-10-151-1&slc_lang=en&sid=1 Asadollah Hosseini-Chegeni hosseinichegeni@gmail.com 0000-0002-7494-8641 Yes Department of Plant Protection, Faculty of Agriculture, University of Lorestan, Khorramabad, Iran Majid Tavakoli Faghihi.f@iums.ac.ir 000-0001-5566-8532 No Lorestan Agricultural and Natural Resources Research Center, Khorramabad, Iran Zakkyeh Telmadarraiy Faghihi.f@iums.ac.ir No Department of Medical Entomology and Vector Control, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran Mohammad Mehdi Sedaghat Faghihi.f@iums.ac.ir 0000-0001-8381-2482 No Department of Medical Entomology and Vector Control, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran Faezeh Faghihi Faghihi.f@iums.ac.ir 0000-0003-1657-6242 No Cellular and Molecular Research Center, Iran University of Medical Sciences, Tehran, Iran
