Does Rickettsia cause Q fever?

Rickettsia, Orientia, and Coxiella cause undifferentiated febrile illnesses of varying severity in humans. Diseases caused by Rickettsia and Orientia species are together referred to as rickettsioses, and Q fever (QF) caused by Coxiella burnetii is frequently included under rickettsioses [1].

Does Coxiella burnetii cause infective endocarditis?

Coxiella burnetii is a common cause of blood culture-negative infective endocarditis (IE). Molecular detection of C burnetii DNA in clinical specimens is a promising method of diagnosing Q fever endocarditis.

How does Coxiella burnetii reproduce?

Coxiella reproduce by binary fission. They are durable organisms, capable of reproduction in the presence of chemicals such as acid hydrolases and defensins, which are bactericidal. It has been suggested that SLPs are released from degenerating LCVs, and that the SLPs are precursors to SCV cells.
