Q fever is an infectious zoonotic disease characterized by sudden fever, headache, and atypical pneumonia, caused by Coxiella burnetii – an obligatory intracellular parasite. Based on phylogenetic analysis of the genes sequences, the classification was changed and C. burnetii species was included to the gamma subgroup of the proteobacteria, Legionellales order and Coxiellaceae family. This analysis...
Many bacterial species can be a cause of various heart diseases, such as: Borrelia burgdorferi sensu lato, Coxiella burnetii and Bartonella spp. The aim of the present studies was to establish if any tick-borne infections can contribute to serious heart disorders resulting in the need for heart transplantation. Myocardium, aortic and mitral valve samples from hearts removed from patients undergoing...
Apoptosis is a genetically controlled mechanism of cell death involved in the regulation of tissue homeostasis. The aim of this study was to investigate the influence of Borrelia afzelii, Coxiella burnetii, and Bartonella henselae bacteria on apoptosis measured as the level of caspase 3 activity in human fibroblast cells HEL-299. Our findings show that C. burnetii bacteria may inhibit the process...
Coxiella burnetii is the etiologie agent of Q fever, a worldwide distributed zoonosis, accountable for serious health problem both for humans and animals. The exposure to C. burnetii infected animals and their products is the main risk factor for Q fever in humans. Several outbreaks of Q fever have been described in Poland which sources were recognized to be related to imported animals and their products...
