Prosthetic arteriovenous (AV) graft infection is the principal cause of morbidity related to chronic hemodialysis AV graft fistula. Coxiella burnetii is a known pathogen that causes fever, pneumonia, and intravascular infections with the limitation of negative cultures. Herein, we report the first case of a patient who presented to the emergency department of our hospital with a prosthetic hemo...

background: there is a little data on coxiella burnetii (q fever agent) in iran. ticks may play a significant role in the transmission of c. burnetii among animals . the aim of this study was to use polymerase chain reaction for the detec­tion of c. burnetii in ticks collected in southeast iran. methods : one hundred and sixty ticks were collected from domestic animals in three localities of ke...

background :  q fever is a zoonotic disease caused by inhalation of the bacterium coxiella burnetii . ruminant livestock are common reservoirs for c. burnetii , and bacteria present in aerosols derived from the waste of infected animals can infect humans . c. burnetii is thought to infect humans primarily via airborne transmission. methods : 64 environmental swab samples were collected from 24 ...

Serological examination of humans in Slovakia suspected of having rickettsial infections revealed the presence of antibodies to spotted fever group rickettsiae (R. conorii, R. slovaca, and R. typhi). Of interest is the finding of serological positivity to the newly recognized "IRS" agent. Antibodies to these rickettsiae and to C. burnetii were demonstrated also in domestic and hunting dogs and ...

Bacteriol. 88:1205-1210. 1964.-Purified suspensions of Coxiella burnetii were shown to utilize alpha-ketoglutarate, succinate, fumarate, malate, oxaloacetate, pyruvate, glutamate, and serine. The addition of nicotinamide adenine dinucleotide(+) was necessary to el...

Recent studies have shown that ticks harbor Coxiella-like bacteria, which are potentially tick-specific endosymbionts. We recently described the detection of Coxiella-like bacteria and possibly Coxiella burnetii in ticks found from rural areas in Malaysia. In the present study, we collected ticks, including Haemaphysalis bispinosa, Haemaphysalis hystricis, Dermacentor compactus, Dermacentor ste...

Background Q fever is a zoonosis with reported outbreaks in rural areas, related to farms and farm animals. In the urban area, the source of infection is almost always unknown and can be related to windborne spread of Coxiella burnetii. Objective: To emphasize the importance of Coxiella burnetii etiology in prolonged febrile syndrome. We want to point out that Q fever can become a real threat e...
