Differentiating acute Q fever from infections caused by other pathogens is essential. We conducted a retrospective case-control study to evaluate differences in clinical signs, symptoms, and outcomes for 82 patients with acute Q fever and 52 control patients who had pneumonia, fever and lower respiratory tract symptoms, or fever and hepatitis, but had negative serologic results for Q fever. Pat...

BACKGROUND Q fever endocarditis, a chronic illness caused by Coxiella burnetii, can be fatal if misdiagnosed or left untreated. Despite a relatively high positive rate of Q fever serology in healthy individuals in the mainland of China, very few cases of Q fever endocarditis have been reported. This study summarized cases of Q fever endocarditis among blood culture negative endocarditis (BCNE) ...

q fever is a zoonotic disease that occurs worldwide and is caused by the obligate intracellular bacterium coxiella burnetii. the aim of this study was to investigate the presence of c. burnetii infection in aborted sheep in eastern turkey using pcr. a total of 200 fetuses were collected from aborted sheep belonging to 200 herds in different locations in the eastern part of turkey. foetal organ ...

coxiella burnetii is the etiological agent of coxiellosis in animals and q fever (a zoonotic disease) in humans. cattle, sheep and goats are the main reservoirs of infection for humans. this serological survey was conducted to determine the seroprevalence of coxiellosis in sheep and goat populations in khorasan razavi province, iran. four hundred and sixty animals (255 sheep from 29 herds in 12...

Patients with a lower respiratory tract infection (LRTI) might be at risk for long-term impaired health status. We assessed whether LRTI patients without Q fever are equally at risk for developing long-term symptoms compared to LRTI patients with Q fever. The study was a cross-sectional cohort design. Long-term health status information of 50 Q fever-positive and 32 Q fever-negative LRTI patien...

Since 2007, the Netherlands has experienced a large Q fever outbreak. To identify and quantify risk factors for development of chronic Q fever after Coxiella burnetii infection, we performed a case-control study. Comorbidity, cardiovascular risk factors, medications, and demographic characteristics from 105 patients with proven (n = 44), probable (n = 28), or possible (n = 33) chronic Q fever w...
