Predominant immunoglobulin A response to phase II antigen of Coxiella burnetii in acute Q fever. (1/454)

Diagnosis of acute Q fever is usually confirmed by serology, on the basis of anti-phase II antigen immunoglobulin M (IgM) titers of >/=1:50 and IgG titers of >/=1:200. Phase I antibodies, especially IgG and IgA, are predominant in chronic forms of the disease. However, between January 1982 and June 1998, we observed anti-phase II antigen IgA titers of >/=1:200 as the sole or main antibody response in 10 of 1,034 (0.96%) patients with acute Q fever for whom information was available. In order to determine whether specific epidemiological or clinical factors were associated with these serological profiles, we conducted a retrospective case-control study that included completion of a standardized questionnaire, which was given to 40 matched controls who also suffered from acute Q fever. The mean age of patients with elevated phase II IgA titers was significantly higher than that usually observed for patients with acute Q fever (P = 0.026); the patients were also more likely than controls to live in rural areas (P = 0.026) and to have increased levels of transaminase in blood (P = 0.03). Elevated IgA titers are usually associated with chronic Q fever and are directed mainly at phase I antigens. Although the significance of our findings is unexplained, we herein emphasize the fact that IgA antibodies are not specific for chronic forms of Q fever and that they may occasionally be observed in patients with acute disease. Moreover, as such antibody profiles may not be determined by most laboratories, which test only for total antibody titers to phase I and II antigens, the three isotype-specific Ig titers should be determined as the first step in diagnosing Q fever.  (+info)

Functional analysis of the active partition region of the Coxiella burnetii plasmid QpH1. (2/454)

The partition region qsopAB of the Coxiella burnetii plasmid QpH1 was analyzed. Locus qsopA alone appears to fulfill the partitioning function; QsopA represses its own promoter 17-fold. Two partition-associated incompatibility sites were identified: incA in a 200-bp region covering the qsopA promoter and incB in the qsopB locus.  (+info)

Q fever in Bulgaria and Slovakia. (3/454)

As a result of dramatic political and economic changes in the beginning of the 1990s, Q-fever epidemiology in Bulgaria has changed. The number of goats almost tripled; contact between goat owners (and their families) and goats, as well as goats and other animals, increased; consumption of raw goat milk and its products increased; and goats replaced cattle and sheep as the main source of human Coxiella burnetii infections. Hundreds of overt, serologically confirmed human cases of acute Q fever have occurred. Chronic forms of Q fever manifesting as endocarditis were also observed. In contrast, in Slovakia, Q fever does not pose a serious public health problem, and the chronic form of infection has not been found either in follow-ups of a Q-fever epidemic connected with goats imported from Bulgaria and other previous Q-fever outbreaks or in a serologic survey. Serologic diagnosis as well as control and prevention of Q fever are discussed.  (+info)

Coxiella burnetii infection increases transferrin receptors on J774A. 1 cells. (4/454)

Inoculation with viable, but not inactivated, Coxiella burnetii resulted in the increased expression of transferrin receptors (TfR) in the murine macrophage-like cell line J774A.1. This upregulation was evident in immunoblots as early as 6 h postinfection, with TfR levels continuing to increase through the first 24 h of infection. Fluorescent labeling revealed that TfR upregulation occurred throughout infected monolayers, eliminating the possibility that it reflected a response by a minor subset of host cells. In addition, TfR trafficking did not appear to be affected by C. burnetii infection. Consistent with the increase in TfRs, inoculation with viable C. burnetii resulted in a 2.5-fold increase in total cellular iron by 12 h postinoculation. Our further findings that the chelation of intracellular iron arrests C. burnetii replication and that C. burnetii metabolic activities in vitro are affected by iron concentration suggest that TfR upregulation is a salient factor in C. burnetii infection, and we speculate that it may represent a significant virulence mechanism.  (+info)

Long term vascular complications of Coxiella burnetii infection in Switzerland: cohort study. (5/454)

OBJECTIVE: To evaluate the range of long term vascular manifestations of Coxiella burnetii infection. DESIGN: Cohort study in Switzerland of people affected in 1983 by the largest reported outbreak of Q fever and who were followed up 12 years later. Follow up information about possible vascular disease and endocarditis was obtained through a mailed questionnaire and death certificates. SETTING: Val de Bagnes, a rural Alpine valley in Switzerland. PARTICIPANTS: 2044 (87%) of 2355 people who had serum testing for Coxiella burnetii infection in 1983: 1247 were classed as not having been infected, 411 were classed as having been acutely infected, and 386 were classed as having been infected before 1983. MAIN OUTCOME MEASURES: Relative risk controlled for age and sex and 12 year risk of vascular diseases and endocarditis among infected participants as compared with those who had never been infected. RESULTS: The 12 year risk of endocarditis or venous thromboembolic disease was not increased among those who had been acutely infected. The 12 year risk of arterial disease was significantly higher among those who had been acutely infected (7%) as compared with those who had never been infected (4%) (relative risk 2.2, 95% confidence interval 1.4 to 3.6). Specifically, there was an increased risk of developing a cerebrovascular accident (relative risk 3.7, 1.6 to 8.4) and cardiac ischaemia (relative risk 1.9, 1.04 to 3.4). 12 year mortality was significantly higher among the 411 people who had been acutely infected in 1983 (9.7%; age adjusted relative risk 1.8, 1.2 to 2.6) when compared with the 1247 participants who had remained serologically negative in 1983 (7.0%). CONCLUSIONS: Coxiella burnetii infection may cause long term complications including vascular disease.  (+info)

Short report: prevalence of antibodies against spotted fever, murine typhus, and Q fever rickettsiae in humans living in Zambia. (6/454)

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. typhi, and C. burnetii was 16.7%, 5.0%, and 8.2%, respectively. The rates of antibody positivity against R. conorii and C. burnetii were higher in the eastern (23.1% and 11.8%) and western (16.8% and 7.4%) areas of Zambia than in the northern (3.0% and 3.0%) area of this country. There was little difference among the three areas in the distribution of antibodies against R. typhi. Since cattle breeding is more extensive in the western and eastern areas than in the northern area, it is thought that cattle-breeding areas are foci of R. conorii and C. burnetii infections in Zambia.  (+info)

Coxiella burnetii pericarditis: report of 15 cases and review. (7/454)

Q fever is characterized by its clinical polymorphism, and pericarditis associated with Q fever has occasionally been described. Herein we report 15 cases of Coxiella burnetii pericarditis, 9 from our data bank and 6 encountered within the past 12 months. Three patients presented with life-threatening tamponade. We compare our cases with the 18 previously reported and with 60 Q fever-matched controls at our center. This study showed that Q fever pericarditis can present as acute as well as chronic disease; we describe relapse after 6 months in association with a serological profile compatible with the chronic form of disease (phase I C. burnetii IgG titer of > or = 800). Discriminant factors among patients and controls are age of > 52 years (adjusted odds ratio [OR], 5.66), the occurrence of general symptoms such as arthralgias or myalgias (adjusted OR, 6.54), and a normal erythrocyte sedimentation rate (adjusted OR, 16.37). No specific symptoms or underlying cardiac predispositions are observed.  (+info)

Q fever. (8/454)

Q fever is a zoonosis with a worldwide distribution with the exception of New Zealand. The disease is caused by Coxiella burnetii, a strictly intracellular, gram-negative bacterium. Many species of mammals, birds, and ticks are reservoirs of C. burnetii in nature. C. burnetii infection is most often latent in animals, with persistent shedding of bacteria into the environment. However, in females intermittent high-level shedding occurs at the time of parturition, with millions of bacteria being released per gram of placenta. Humans are usually infected by contaminated aerosols from domestic animals, particularly after contact with parturient females and their birth products. Although often asymptomatic, Q fever may manifest in humans as an acute disease (mainly as a self-limited febrile illness, pneumonia, or hepatitis) or as a chronic disease (mainly endocarditis), especially in patients with previous valvulopathy and to a lesser extent in immunocompromised hosts and in pregnant women. Specific diagnosis of Q fever remains based upon serology. Immunoglobulin M (IgM) and IgG antiphase II antibodies are detected 2 to 3 weeks after infection with C. burnetii, whereas the presence of IgG antiphase I C. burnetii antibodies at titers of >/=1:800 by microimmunofluorescence is indicative of chronic Q fever. The tetracyclines are still considered the mainstay of antibiotic therapy of acute Q fever, whereas antibiotic combinations administered over prolonged periods are necessary to prevent relapses in Q fever endocarditis patients. Although the protective role of Q fever vaccination with whole-cell extracts has been established, the population which should be primarily vaccinated remains to be clearly identified. Vaccination should probably be considered in the population at high risk for Q fever endocarditis.  (+info)

CBSRP : Coxiella burnetii, the causative agent of Q fever, is a small obligately intracellular bacterium, which is associated with animals. It is acquired through aerosol exposure and generally causes mild respiratory disease. A small number of acute cases advance to a chronic infection, which typically manifests as endocarditis. Left untreated, Q fever endocarditis may be fatal. Serologic and histopathologic studies may be nonspecific and subjective, respectively, limiting usefulness for patient diagnosis.   Evaluation of infected tissue, blood, or serum using PCR may be a useful tool for diagnosing some cases of Coxiella burnetii infection. Mayo Medical Laboratories has developed a real-time PCR test that rapidly detects Coxiella burnetii DNA in clinical specimens by targeting a sequence of the shikimate dehydrogenase gene (aroE) unique to Coxiella burnetii.

BACKGROUND: Prior to the 2007-2010 Q fever epidemic in the Netherlands, the seroprevalence of antibodies against Coxiella burnetii in the general population was 1.5%, which is low compared to other countries. We aimed to determine the seroprevalence after the Q fever epidemic among people living in the affected area, compare ... read more the seroprevalence with the incidence of Q fever notifications during the 2007-2010 Q fever epidemic, and to identify farm exposures associated with having antibodies against C. burnetii. METHODS: During the period March 2014-February 2015, residents aged 18-70 years from two provinces were invited by general practitioners to complete a questionnaire on their symptoms and personal characteristics and to submit a blood sample. We used the mandatory provincial database of livestock licences to calculate distance to farms/farm animals for each participant. To compare ELISA-positive participants for C. burnetii antibodies with those who were negative, we calculated ...
Coxiella burnetii is an intracellular bacterial pathogen that causes Q fever. Infected pregnant goats are a major source of human infection. However, the tissue dissemination and excretion pathway of the pathogen in goats are still poorly understood. To better understand Q fever pathogenesis, we inoculated groups of pregnant goats via the intranasal route with a recent Dutch outbreak C. burnetii isolate. Tissue dissemination and excretion of the pathogen were followed for up to 95 days after parturition. Goats were successfully infected via the intranasal route. PCR and immunohistochemistry showed strong tropism of C. burnetii towards the placenta at two to four weeks after inoculation. Bacterial replication seemed to occur predominantly in the trophoblasts of the placenta and not in other organs of goats and kids. The amount of C. burnetii DNA in the organs of goats and kids increased towards parturition. After parturition it decreased to undetectable levels: after 81 days post-parturition in goats and
The objective of this study was to investigate the prevalence of Coxiella burnetii in two domestic ruminant species (cattle and sheep) and the western grey kangaroo (Macropus fuliginosus) in Western Australia (WA). The IDEXX CHEKiT Q Fever ELISA and CFT were used to test sera from 50 sheep and 329 head of cattle for anti- C. burnetii antibodies and 343 kangaroo sera were tested using an indirect ELISA developed specifically for this study. Faecal or urine samples collected from the same animals were tested with two PCR assays to identify active shedding of C. burnetii in excreta. Only two of the 379 ruminant sera had detectable levels of anti- C. burnetii antibodies according to the ELISA while the CFT did not detect any positive samples. In contrast 115 of the 343 western grey kangaroo serum samples were positive when tested with the antibody-ELISA. The first qPCR assay, targeting the IS1111a element, identified 41 of 379 ruminant and 42 of 343 kangaroo DNA samples as positive for C. burnetii ...
Coxiella burnetii symptoms, causes, diagnosis, and treatment information for Coxiella burnetii (Q fever) with alternative diagnoses, full-text book chapters, misdiagnosis, research treatments, prevention, and prognosis.
Coxiella burnetii, a gram-negative obligate intracellular bacterium, causes human Q fever and is considered a potential agent of bioterrorism. Distinct genomic groups of C. burnetii are revealed by restriction fragment-length polymorphisms (RFLP). Here we comprehensively define the genetic diversity …
Q fever caused by Coxiella burnetii is transmitted to humans by inhalation of aerosols from animal birth products. Q fever in pregnancy is suspected to be a potential cause of fetal and maternal morbidity and fetal mortality but the pathogenesis is poorly understood, and even in Q fever endemic areas, the magnitude of a potential association is not established. We aimed to examine if presence of antibodies to C. burnetii during pregnancy or seroconversion were associated with adverse pregnancy outcomes. The Danish National Birth Cohort collected blood samples and interview data from 100,418 pregnant women (1996-2002). We sampled 397 pregnant women with occupational or domestic exposure to cattle or sheep and a random sample of 459 women with no animal exposure. Outcome measures were spontaneous abortion, preterm birth, birth weight and Small for Gestational Age (SGA). Blood samples collected in pregnancy were screened for antibodies against C. burnetii by enzyme-linked immunosorbent assay (ELISA).
Abstract. We used a seroepidemiologic study to estimate Q fever (Coxiella burnetii) seroprevalence, seroincidence, and risk factors for seroconversion in two deployed military populations in 2005. The first study group resided in an area with a known Q fever outbreak history (Al Asad, Iraq). Of this population, 7.2% seroconverted for an incidence rate of 10.6 seroconversions per 1,000 person-months. The second population included personnel transiting through Qatar on mid-deployment leave from southwest/central Asia. In this group, we found 2.1% prevalence with 0.92 seroconversions per 1,000 person-months. However, no significant risk factors for Q fever seroconversion were found in either population.
The intervening sequence (IVS) of Coxiella burnetii, the agent of Q fever, is a 428-nt selfish genetic element located in helix 45 of the precursor 23S rRNA. The IVS element, in turn, contains an ORF that encodes a hypothetical ribosomal S23 protein (S23p). Although S23p can be synthesized in vitro in the presence of an engineered E. coli promoter and ribosome binding site, results suggest that the protein is not synthesized in vivo. In spite of a high degree of IVS conservation among different strains of C. burnetii, the region immediately upstream of the S23p start codon is prone to change, and the S23p-encoding ORF is evidently undergoing reductive evolution. We determined that IVS excision from 23S rRNA was mediated by RNase III, and IVS RNA was rapidly degraded, thereafter. Levels of the resulting 23S rRNA fragments that flank the IVS, F1 (~1.2 kb) and F2 (~1.7 kb), were quantified over C. burnetiis logarithmic growth phase (1-5d). Results showed that 23S F1 quantities were consistently higher

Summary Minced chick-embryo tissue, bathed in a lactalbumin growth medium and planted on a modified Zinsser's agar medium, supported excellent growth of Coxiella burnetii. Titration of the viable rickettsial content of samples taken during the growth curve indicated proliferation of rickettsiae. Spectrophotometric measurements of purified suspensions of rickettsiae isolated from cultures incubated for varying periods also showed that growth had occurred. Other ancillary observations indicated that the final yield in mouse- or chick-embryo cultures was comparable to that produced in yolk-sac cultures.

This is a collaborative project between veterinary and medical colleagues from NSW and Queensland to determine the importance of Q fever in the veterinary community as well as the broader Australian population. It brings together veterinarians from the University of Sydney (Assoc. Prof. Jacqui Norris, Dr Katrina Bosward, Dr Navneet Dhand), Charles Sturt University (Dr Jane Heller), the University of Queensland (Dr Rowland Cobbold) and James Cook University as well as medical colleagues from Sydney (Dr Nicholas Wood, Professor Peter McIntyre, Dr Heather Gidding, Professor Dominic Dwyer), the New England/Hunter region (Prof David Durrheim, Assoc. Prof. Stephen Graves), Brisbane (Professor Michael Nissen, Mrs Sarah Tozer, Dr Theo Sloots) and north east Queensland (Townsville, Dr Peter Massey).. Q fever is a ubiquitous zoonotic disease of worldwide importance caused by the bacterium Coxiella burnetii. It is classified as a category B bioterrorism agent and is a significant cause of acute and chronic ...
Q fever is caused by the bacterium Coxiella burnetii and has both acute and chronic forms. The acute disease is a febrile illness often with headache and myalgia that can be self-limiting, whereas the chronic disease typically presents as endocarditis and can be life threatening. The normal therapy for the acute disease is a 2 week course of doxycycline, whereas chronic disease requires 18-24 months of doxycycline in combination with hydroxychloroquine. Alternative treatments are used for pregnant women, young children and those who cannot tolerate doxycycline. Doxycycline resistance is rare, but has been reported. Co-trimoxazole is a currently recommended alternative treatment, but quinolones, rifampin and newer macrolides may also provide some benefit ...
The scope and overall interpretation of our report on the re-evaluation of the fixed, paraffin-embedded tissue samples taken at patient BIs autopsy are necessarily limited by the absence of diagnostic results of any serological or other tests for candidate infective organisms at the time of the "viral encephalitis" in 1986 (see review [17]). Nevertheless, taken together, the extended laboratory tests with C.b. specific monoclonal antibodies and PCR (COM1 and IS1111a genes) on a range of post mortem specimens suggest that the most compelling and coherent explanation of BIs illness from 1986 to 1996, is one of a severe attack of primary Q fever and a subsequent multisystem organ dysfunction with dissemination of the coxiella throughout the body, ending in 1996 with cardiac and cerebral dysfunction i.e., a complex, severe idiopathic illness labelled descriptively at the time as "post (viral) infection fatigue syndrome" (PIFS).. An epidemiological and clinical association between ...
Catalyzes the reductive methylation of 2-deoxyuridine-5-monophosphate (dUMP) to 2-deoxythymidine-5-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by-product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.
The focus of our research is to understand the molecular and cellular events that enable microbial pathogens to evade host defense mechanisms. In particular, we are interested in how bacteria that replicate inside mammalian cells create specialized vacuoles that support pathogen replication. We have been using Legionella pneumophila and Coxiella burnetii as model pathogens to study this process. We have been characterizing a type IV secretion system called Dot/Icm that delivers bacterial effector proteins into the eukaryotic host cell cytosol. The goals of this research are to determine the mechanism by which these bacterial effector proteins regulate phagosome maturation, modulate host immunity, and subvert eukaryotic cell functions..

Nucleotide excision repair (NER) is a mechanism to recognize and repair bulky DNA damage caused by compounds, environmental carcinogens, and exposure to UV-light. In humans hereditary defects in the NER pathway are linked to at least three diseases: xeroderma pigmentosum (XP), Cockayne syndrome (CS), and trichothiodystrophy (TTD). The repair of damaged DNA involves at least 30 polypeptides within two different sub-pathways of NER known as transcription-coupled repair (TCR-NER) and global genome repair (GGR-NER). TCR refers to the expedited repair of lesions located in the actively transcribed strand of genes by RNA polymerase II (RNAP II). In GGR-NER the first step of damage recognition involves XPC-hHR23B complex together with XPE complex (in prokaryotes, uvrAB complex). The following steps of GGR-NER and TCR-NER are similar ...
Homologous recombination (HR) is essential for the accurate repair of DNA double-strand breaks (DSBs), potentially lethal lesions. HR takes place in the late S-G2 phase of the cell cycle and involves the generation of a single-stranded region of DNA, followed by strand invasion, formation of a Holliday junction, DNA synthesis using the intact strand as a template, branch migration and resolution. It is investigated that RecA/Rad51 family proteins play a central role. The breast cancer susceptibility protein Brca2 and the RecQ helicase BLM (Bloom syndrome mutated) are tumor suppressors that maintain genome integrity, at least in part, through HR ...

The increases in MAP and HR recorded via telemetry during the first week after CBU are very similar to results published previously based on daily recordings with the dog resting quietly in a sling under laboratory conditions (28). The effects of CBU on PRA were also replicated; PRA was elevated on some days during the week following CBU but never suppressed below control levels. Furthermore, we also observed a significant increase in plasma NE in response to CBU. All of these responses are compatible with the hypothesis that CBU caused an increase in sympathetic outflow. However, contrary to our expectations, the initial increases in MAP, HR, and plasma NE were not sustained. Plasma NE and HR declined to control levels by the third week after CBU (Figs. 4 and 7). There was also a decline in MAP over the same time period, but MAP stabilized at a level that averaged 10 ± 3 mmHg above control during the third to fifth weeks after CBU (Fig. 2). There are a number of possibilities that could ...

The first case of Q fever in Taiwan was reported in 1993. The disease is considered to be emerging in Taiwan, but the route of transmission has remained unclear. The annual number of confirmed Q fever cases has been increasing up to more than 100 cases since 2005, comparing with less than 30 before 2003. The purpose of this study was to determine the seroprevalence and risk factors of Coxiella burnetii infection in veterinary-associated populations in southern Taiwan. A total of 228 serum samples of high risk individuals engaging in veterinary-related work or animal-farm work, were collected between March and June in 2007. The study individuals were interviewed by a structured questionnaire designed for Q fever investigation. Serum samples from different animal species were also obtained for Q fever analysis in the same study areas. Serological test was conducted by indirect immunofluorescence antibody assay (IFA). The result demonstrated the overall seroprevalence of Q fever was 26.3% in ...
Q fever bacteria (Coxiella burnetii, yellow), coloured transmission electron micrograph (TEM). Q fever is a rare livestock disease that can be spread to humans through inhalation of contaminated particles. It is considered the worlds most infectious disease, as just one bacterium is capable of causing infection. It causes flu-like symptoms including fever, headache and nausea. It can also lead to hepatitis, pneumonia or inflammation of the heart lining, all of which can be fatal. Magnification: x900 when printed 10 centimetres wide. - Stock Image C002/5597
Q fever, a rickettsial infection caused by Coxiella burnetii, has been recognized as a widely distributed zoonosis with the potential for causing both sporadic and epidemic disease. The resistance of Coxiella burnetii to heat, chemical agents, and desiccation allows the agent to survive for extended periods outside the host.. The infection is spread by the inhalation of infected material, mainly from sheep and goats. They shed the organism in feces, milk, nasal discharge, placental tissue, and amniotic fluid.. The clinical spectrum of disease ranges from unapparent to fatal. Respiratory manifestations usually predominate; endocarditis and hepatitis can be complications.. During the course of the infection, the outer membrane of the organism undergoes changes in its lipopolysaccharide structure, called phase variation. Differences in phase I and phase II antigen presentation can help determine if the infection is acute or chronic:. -In acute Q fever, the phase II antibody is usually higher than ...
To increase understanding of human bacterial and parasitic pathogens in bats, we investigated the prevalence of Babesia spp., Rickettsia spp., Anaplasma spp. and Coxiella burnetii in bats from China. Bats were captured from Mengyin County, Shandong Province of China using nets. DNA was extracted from the blood and spleen of bats for molecular detection of Babesia spp., Rickettsia spp., Anaplasma spp. and Coxiella burnetii with specific primers for each species. A total of 146 spleen samples and 107 blood samples of insectivorous bats, which belonged to 6 species within two families, were collected from Mengyin County, Shandong Province of China. We found that two Eptesicus serotinus (2/15, 13.3%) were positive for Babesia vesperuginis. We were unable to detect genomic sequences for Rickettsia spp., Anaplasma spp. and Coxiella burnetii. To our knowledge, our study showed for the first time the presence of Babesia vesperuginis in Eptesicus serotinus collected from China, suggesting that Babesia
Q fever is a disease of humans, caused by Coxiella burnetii, and a large range of animals can be infected. This paper presents a review of the epidemiology of Q fever in humans and farm animals between 1982 and 2010, using case studies from four European countries (Bulgaria, France, Germany and the Netherlands). The Netherlands had a large outbreak between 2007 and 2010, and the other countries a history of Q fever and Q fever research. Within all four countries, the serological prevalence of C. burnetii infection and reported incidence of Q fever varies broadly in both farm animals and humans. Proximity to farm animals and contact with infected animals or their birth products have been identified as the most important risk factors for human disease. Intrinsic farm factors, such as production systems and management, influence the number of outbreaks in an area. A number of disease control options have been used in these four countries, including measures to increase diagnostic accuracy and general

Coxiella burnetii is the etiological agent of the worldwide distributed zoonosis Q fever. This review gives a comprehensive overview about the etiological agent and epidemiology of C. burnetii. Moreover, the role of arthropod vectors in transmission of C. burnetii is discussed. Detailed information is provided about current diagnostics and vaccination and importantly the most recent developments for improving the respective measures in animals. Immunoproteomic approaches are presented aimed to replace currently used whole cell antigen with well-defined and reproducible epitopes. Ruminants are considered as the main reservoir for human infections. The often subclinical infection in animals and suboptimal sensitivity of diagnostics hamper the identification of infected animals, while effectiveness of the current vaccine is questionable. New strategies based on advanced diagnostics and vaccines in animals will have the potential to prevent Q fever spreading and transmission to humans.
Q fever is a disease acquired from animals caused by Coxiella burnetii, a rickettsialike organism of low virulence but remarkable infectivity. A single organism can cause illness. In addition, despite the fact that C burnetii is unable to grow or replicate outside host cells, a sporelike form of the organism is extremely resistant to heat, pressure, and many disinfectants. This allows C burnetii to persist in the environment for long periods under harsh conditions. In contrast to this high degree of inherent resilience and transmissibility, the acute clinical disease associated with Q fever is usually a benign, although temporarily incapacitating, illness in humans ...

To assess Q fever in France, we analyzed data for 1985-2009 from the French National Reference Center. A total of 179,794 serum samples were analyzed; 3,723 patients (one third female patients) had acute Q fever. Yearly distribution of acute Q fever showed a continuous increase. Periodic variations were observed in monthly distribution during January 2000-December 2009; cases peaked during April-September. Q fever was diagnosed more often in patients in southeastern France, where our laboratory is situated, than in other areas. Reevaluation of the current positive predictive value of serologic analysis for endocarditis was performed. We propose a change in the phase I (virulent bacteria) immunoglobulin G cutoff titer to >1,600. Annual incidences of acute Q fever and endocarditis were 2.5/100,000 persons and 0.1/100,000 persons, respectively. Cases and outbreaks of Q fever have increased in France.
Context Diagnosis of infective endocarditis (IE), particularly in blood culture-negative patients, has been a problem and requires further investigations. Aim This study was designed to evaluate the added value of a commercial multiplex PCR performed on blood in the early diagnosis of IE and compare its performance with conventional blood culture and serological testing, at a tertiary care center in Egypt. Settings and design Thirty-seven cases of diagnosed definite endocarditis were enrolled in the study. Patients and methods For each patient, blood culture was prepared and serum sample was obtained for serology testing for Brucella spp., Bartonella spp., Coxiella burnetii antibodies, and Aspergillus galactomannan antigen. Patients were selected for commercial Seegene multiplex PCR (sepsis screening) when their blood culture remained negative after 24 h incubation. Statistical analysis Sensitivity, specificity, positive predictive value, negative predictive value, and κ-test were used in ...

Coxiella burnetti can induce abortion in domestic mammals (cat, dog, rabbit) and ruminants, and these animals represent their main reservoir. The danger posed by Coxiella is that they can be excreted by animals exhibiting no apparent clinical signs of the disease, whether following natural infection or because the animals have been vaccinated with an ineffective vaccine.

Cerebral palsy (CP) is a group of neurodevelopmental conditions with abnormal movement and posture resulted from a non-progressive cerebral disturbance. It is the most common cause of motor disability in childhood. Most therapies are palliative rather than restorative. Umbilical cord blood (UCB) may be used as restorative approach for children with CP.. Many experimental animal studies have revealed that UCB is beneficial to improve and repair neurological injuries, this effect achieved due to immune regulation and angiogenesis as well as the neuroprotective effect.. Based on animal studies and some clinical trials, UCB is suggested as a potential therapy for children with CP.. This study is prospective, non randomized (open label) with control group.

Is Q fever spread from person to person?. No. It is most often spread by contact with contaminated straw or manure. It can also be spread by inhaling contaminated dust or soil, ingesting raw milk or skinning wild rabbits.. How will I know if I have been exposed to Q fever?. It will depend on how the germ was released, where it was released, and where you were in relation to the release site. The further away you were from the release site the less likely it will be that you were exposed.. How soon will symptoms develop (incubation period)?. Symptoms may start in two to 14 days after you have been exposed.. What are the symptoms of Q fever?. Symptoms may include fever, dry cough, severe headache, tiredness, chills, swets, sore muscles, nausea, vomiting, diarrhea, and pain when taking a deep breath. Not all persons who are exposed will get sick.. How is Q fever treated?. If you have symptoms of this infection, your health care provider will give you an antibiotic.. How is Q fever prevented?.

Derrick1 in 1937 reported nine cases of a new clinical entity in Queensland, Australia, which he designated as "Q fever." Burnet2 isolated the etiologic agent in these cases and correctly identified it as a rickettsia. Until recently, most physicians have considered this disease little more than a medical curiosity, and one of importance only in Australia and in the western areas of the United States. It has become increasingly apparent that this is a widespread disease entity found in many sections of the United States and most countries of the world.3 Many cases of Q fever are unrecognized because of ...

2006 was quite a year for me. I excelled at running, surpassing my wildest dreams and goals. My goals were to PR at all ultra distances 50K-100 mile to 24 hour. I was able to check off that goal. I PRd at 50K, 50 mile, 100 mile and 24 hour. Running McNaughton 2 hours faster than the previous year gave me the confidence I needed to try 100 miles at FANS. FANS scared me. I had dropped out the previous year at 12 hours and hadnt been able to reach 100 miles during my 2 prior attempts. Lo and behold, I was able to run 116.8 miles and capture 2nd woman. CRAZY. Voyaguer 50 mile came along and I wanted to break 1030. I did, 1026. Incredible when you take into account my first V was 1406, then 1234 and 1045. September brought Superior Sawtooth 100 Mile Trail Race. I was confident that I had a good solid training program to get me to the finish.

Tonight I decided to give it a go in the Mines Falls race series. This time I decided to take it easy and try something different. Instead of running the 5k course I ran the 5 miles course (a first for me). I actually enjoyed the course and didnt trip or run into a tree during the last difficult mile (my worry). I dont have the best balance! I also stayed on the course without getting lost. It was the relay race night, but I and a few others ran the whole race. I took it out easy and after a mile started passing a few people. At the relay exchange I got passed again by a fresh runner but soon got my position back. I hit the 3 mile mark at 19:00. I dont know how accurate it was. I picked up the pace just a bit, but then my heart started racing too much all of a sudden (I dont recall that ever happening before). It calmed down after about 20 seconds. I actually liked the variety of terrain and constant turning as opposed to the steady running at the same pace of the 5k course. The last mile ...

The overall animal and farm seroprevalence of C. burnetii in dairy goats farms with ≥ 100 dairy goats observed in this study was 21.4% and 43.1% respectively. These seroprevalence estimates increased compared to the seroprevalence measured in 2008, when 14.7% of individual dairy goats were serologically positive and 17.9% of farms tested positive. The within-herd prevalence on positive dairy goat farms in our study was 46.6% compared to 32.1% (95%CI 28.4%-35.9%) in 2008 (van den Brom R, Moll L, Vellema P: Q fever seroprevalence in sheep and goats in the Netherlands in 2008, submitted). This study demonstrates substantial transmission of C. burnetii within and between dairy goat farms in recent years prior to the mandatory vaccination campaign in the Netherlands.. The relatively low overall participation rate of 37% probably reflects the reluctance to take part in the study at the same time as control measures increased, including finally the culling of pregnant goats at bulk milk PCR-positive ...

In the spring of 1999 in rural Newfoundland, abortions in goats were associated with illness in goat workers. An epidemiologic investigation and a serologic survey were conducted in April 1999 to determine the number of infections, nature of illness, and risk factors for infection. Thirty-seven percent of the outbreak cohort had antibody titers to phase II Coxiella burnetii antigen >1:64, suggesting recent infection. The predominant clinical manifestation of Q fever was an acute febrile illness. Independent risk factors for infection included contact with goat placenta, smoking tobacco, and eating cheese made from pasteurized goat milk. This outbreak raises questions about management of such outbreaks, interprovincial sale and movement of domestic ungulates, and the need for discussion between public health practitioners and the dairy industry on control of this highly infectious organism ...
In other Iraq news, Wednesday the Center for Disease Control issued an alert for a Q Fever Infection: Increasing reports of Q fever among deployed U.S. military personnel due to endemic transmission in Iraq, as well as a large ongoing outbreak of Q fever in the Netherlands, may place travelers to these regions at risk for infection. Healthcare providers in the United States should consider Q fever in the differential diagnosis of persons with febrile illness, pneumonia or hepatitis who have recently been in Iraq or the Netherlands. Physicians are encouraged to submit samples for proper laboratory testing and contact the CDC for consultation if needed. Q fever cases in travelers should be promptly reported to proper authorities. Background Since Operation Iraqi Freedom commenced in 2003, over 200 cases of acute Q fever have been reported among U.S. military personnel deployed to Iraq. Since several of these cases were identified after returning to the U.S. or when they were no longer serving on ...

First isolated in 1977, Legionella pneumophila, a Gram-negative, intracellular bacterial pathogen is the agent causing the severe form of pneumonia named Legionnaires disease, as well as the less severe flu-like Pontiac fever [1]. It has drawn much attention for its capability of intracellular replication in both protozoa and human beings. After the endocytosis by protozoan hosts like amoebae or human alveolar macrophages, the Legionella-containing vacuole (LCV) inhibits phagolysosomal fusion and recruits mitochondria followed by the association of ribosome-studded membranes that later disguise LCV as endoplasmic reticulum (ER). Within this ER-like compartment, the bacterium replicates to high numbers and eventually is released through lysing the host cell for the next invasion [2].. During this process, L. pneumophila requires most protein products of 27 dot/icm (defect in organelle trafficking/intracellular multiplication) genes to constitute a type IVB secretion system (T4BSS) [2]. Although ...
A Q fever vaccine available in Australia has proven to be effective for those who work in high-risk occupations and environments. The vaccine has not been approved for use in the United States at this time. Prevention efforts are primarily aimed at high-risk individuals and reducing environmental contamination and exposure. Individuals working with sheep, goats, and cattle should ensure that they properly dispose of any placenta and other birth products. All exposed holding and birthing areas should be disinfected and decontaminated. Animal holding facilities should be located well away from populated areas. Imported animals should be quarantined and observed for signs of infection. Barns or laboratories housing potentially infected livestock should have restricted access. Lab workers coming in contact with the C. burnetti bacteria should follow proper procedures for bagging, washing, and autoclaving all lab equipment and clothing. It is also important to only use pasteurized dairy products to ...

Background. Although the pathologic examination of cardiac valves remains the reference standard for the diagnosis of infective endocarditis, the detection of microorganisms often poses a challenge for pathologists. This can be done by use of nonspecific histochemical stains or by immunohistochemical analysis, but specific antibodies are often not available. We describe a novel method for the detection of microorganisms in valve specimens from patients with infective endocarditis. Methods. Detection of microorganisms was performed in valve specimens from patients with endocarditis caused by gram-positive cocci (25 specimens), blood culture-negative endocarditis (15 specimens: 6 cases caused by Coxiella burnetii, 5 caused by Tropheryma whipplei, and 4 caused by Bartonella species), or noninfective degenerative damage (30 specimens, used as negative controls), using the patients own serum. This technique, called "autoimmunohistochemistry," is an immunohistochemical peroxidase-based method that we ...
With the escalating number of bacterial genome sequences available, CGH microarray analysis is an increasingly popular tool to study pathogenic microorganisms. CGH is a comprehensive analytical tool permitting the examination of multiple bacterial strains at the whole-genome level, providing data about the acquisition and loss of genetic information, the potential evolutionary lineages of pathogens, and the identification of virulence-associated and/or strain-specific genes. Recently, a number of important bacterial pathogens of humans and animals have been analyzed using CGH, including Bordetella pertussis (23), Vibrio cholerae (26), Helicobacter pylori (85), Coxiella burnetti (3), Yersinia pestis (42), and Aeromonas salmonicida (67).. This is the first study to use CGH microarray analysis to compare a collection of uropathogenic and fecal/commensal E. coli isolates. This approach permits the identification of genomic islands and genes specific to UPEC isolates. Genomic DNA from three ...
Dermacentor, also known as the American Levi tick, is a genus of ticks in the family Ixodidae, the hard ticks. The genus has a cosmopolitan distribution, with native species on all continents except Australia. Most occur in the Nearctic ecozone. Hosts of Dermacentor ticks include many large and small mammals, including horses, deer, cattle, lagomorphs, peccaries, porcupines, tapirs, desert bighorn sheep, and humans. The American dog tick (D. variabilis) is a member of the genus. Dermacentor are vectors of many pathogens, including Rickettsia rickettsii, which causes the disease Rocky Mountain spotted fever, Coxiella burnetii, which causes Q fever, Anaplasma marginale, which causes anaplasmosis in cattle, Francisella tularensis, which causes tularemia, Babesia caballi, which causes equine piroplasmosis, and the Flavivirus that causes Powassan encephalitis. Dermacentor ticks inject a neurotoxin that causes tick paralysis. As of 2010, there are about 34 species in the genus. Dermacentor abaensis ...
The spotted fever rickettsia, Rickettsia helvetica, is an endemic tick-borne bacteria in Sweden. It causes infections in humans, manifested as aneruptive fever, headache, arthralgia and myalgia, and sometimes an inoculation eschar or a rash. There have also been two known cases of human infections with R. felis in Sweden.. The present thesis starts by investigating dispersal of ticks and Rickettsia spp. by migrating birds flying from Africa to Europe. Almost 15,000 birds were searched and 734 ticks collected, mainly of the species Hyalomma marginatum complex. Almost half (48%) of the ticks were infected with Rickettsia spp., 96% of which was R. aeschlimannii, the remaining R. africae and undefined species.. The next study focused on questing ticks over a large area in Sweden and determining the prevalence of Rickettsia spp., Anaplasma spp. and Coxiella burnetii. Rickettsia spp. was found in 9.5-9.6% of the ticks and A. phagocytophilum in 0.7%; no C. burnetii was found.. The last three papers in ...

  • We observed that C. burnetii under in vivo conditions predominantly uses glucose as a carbon source (mostly for biosynthetic processes) and fatty acids for energy generation. (biomedcentral.com)
  • These results suggest that sustained C. burnetii protein synthesis is required for PV fusion with other vacuoles of the endocytic pathway. (nih.gov)
  • These autophagosomal features suggest that Coxiella vacuoles interact with the autophagic pathway. (asm.org)
