This study was aimed at detection of Coxiella burnetii in bovine foetuses using polymerase chain reaction (PCR) and immunohistochemistry (IHC) and at an estimation of its frequency in Eastern Turkey. Stamp, Giemsa, and Gimenez stains were used in addition to PCR and IHC to determine the presence of C. burnetii in samples from 70 bovine foetuses. While the staining methods did not detect the age...

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 Kerma...

For PCR detection of Coxiella burnetii in various clinical specimens we developed a sample preparation method in which silica binding of DNA was used. This method was found to be fast, easily performed with large numbers of samples, and equally sensitive for all of the specimens tested (livers, spleens, placentas, heart valves, milk, blood). The DNA preparation method described here can also be...

Q fever is a zoonosis caused by the bacterium Coxiella burnetii. One of the largest reported outbreaks of Q fever in humans occurred in the Netherlands starting in 2007; epidemiologic investigations identified small ruminants as the source. To determine the genetic background of C. burnetii in domestic ruminants responsible for the human Q fever outbreak, we genotyped 126 C. burnetii-positive s...

The causative agents of rickettsial diseases (Rickettsia conorii, R. typhi, and Coxiella burnetii) have been reported throughout the African continent. However, there have been no reports on epidemiologic surveys of these infections in Zambia. This study was designed to clarify the prevalence of three rickettsioses in 377 humans in Zambia. The seroprevalence of antibodies against R. conorii, R....

Q fever is a zoonotic disease caused by Coxiella burnetii which has a worldwide distribution. Pneumonia occurs in almost half of the patients who have an acute C. burnetii infection. Less than 5-6% of community acquired pneumonia (CAP) is found to be caused by this organism. Endemicity of C. burnetii infection has been recorded in various studies carried out in our country. However there is no ...

Most bacterial diseases associated with sheep and goat abortion have some potential for zoonotic transmission. The main diseases of concern as identified by Edmondson et al (2012) are: Brucella melitensis, C, burnetii (Q fever), Chlamydophila abortus, Salmonella, Toxoplasma gondii and Campylobacter jejuni. Knowledge of abortifacient zoonotic pathogens, their clinical signs, gross lesions and th...

Paretsky, D. (University of Kansas, Lawrence), C. M. Downs, and C. W. Salmon. Some biochemical changes in the guinea pig during infection with Coxiella burnetii. J. Bacteriol. 88:137-142. 1964.-Guinea pigs infected with Coxiella burnetii, the rickettsial agent of Q fever, were studied for 11 days postinfection. Maximal changes in liver lipids, liver phosphorylase, and uridine diphosphate glucos...

BACKGROUND In the Pacific islands countries and territories, very little is known about the incidence of infectious diseases due to zoonotic pathogens. To our knowledge, human infections due to Rickettsia spp., Coxiella burnetii, Ehrlichia spp. and Bartonella spp. have never been reported in French Polynesia; and infections due to C. burnetti have been reported worldwide except in New Zealand. ...

BACKGROUND Coxiella burnetii is an important zoonotic pathogen of global distribution. Still, in most parts of South America including Chile, systematic epidemiological data are lacking. The presented study aims to determine the seroprevalence of Coxiella burnetii antibodies in healthy adults of four different regions in Chile. METHODS A cross-sectional study was performed, which included hea...
