Q Fever Endocarditis in Northeast Iran

Seroepidemiology of coxiellosis (Q fever) in sheep and goat populations in the northeast of Iran

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...

Chronic Q fever endocarditis.

Eight patients with chronic Q fever endocarditis were treated with tetracycline for up to 40 months. In addition, five of these patients received co-trimoxazole. Six patients had prosthetic valves. Two patients who had Q fever endocarditis on their native valves required valve replacement because of haemodynamic difficulties: in only one did the Q fever endocarditis contribute to the haemodynam...

Chronic Q fever endocarditis.

Q fever tricuspid valve endocarditis.

Q fever is a zoonosis caused by Coxiella burnetii. The most frequent clinical expression of the chronic form is a bacterial culture negative aortic or mitral endocarditis. A case of tricuspid valve endocarditis due to C burnetii is described, with a favourable outcome after treatment with doxycycline and hydroxychloroquine.

Q fever a Forgotten Disease in Iran

There have already been a few studies on Q fever in Iran and most of them go back to more than 50 years ago. Preliminary serologic studies on ruminants and febrile patients in Southeast Iran show a high seropositivity in this region. Misdiagnosis as well as poor attention of public health authorities to this infection can facilitate the epidemic spread of Q fever. Further studies on the diagnos...
