Although the hypothesis of transmission of Q fever by tick bite still remains controversial, to further study this point is of interest. Acknowledgements We thank Dr. Marco Quevedo, from the Institute of Virology, Bratislava, Slovakia, and Dra. Fatima Bacelar from the Vorinostat ic50 Centro de Estudos de Vectores y Doenças Infecciosas, Aguas de Moura, Portugal, for their help in setting up the culture method for C. burnetii, and Aleida Villa, from EXOPOL, Zaragoza, Spain, for providing local
strains from livestock. We are grateful to COST action B28 C05.0103 “Array technologies for BSL3 and BSL4 pathogens” AP26113 price for providing a platform of cooperation and for the exchanging of bacterial strains with other European BMN 673 research buy laboratories, specifically with the Bundeswehr Institute of Microbiology, Munich, Germany (Dr. Dimitrios Frangoulidis) and the Institute of Virology, Slovak Academy of Sciences, Bratislava, Slovakia (Dr. Rudolf Toman).
