Objetivo Evaluar cuatro tecnicas de analisis de inmunoabsorcion ligada a enzimas (ELISA) (comercializadas por Panbio y Serion) para la deteccion de inmunoglobulinas (IgM e IgG) en un brote de fiebre Q. Metodos Se procesaron 53 muestras de suero correspondientes a 29 personas. El metodo de referencia fue inmunofluorescencia indirecta (IFI). Resultados La sensibilidad y especificidad en la deteccion de IgM fueron del 100 y del 74% (Panbio) y del 91 y el 88% (Serion). La sensibilidad para IgG fue…

Brote de fiebre Q en un área urbana asociado a la visita a una granja-escuela
TLDR
La investigacion of los antecedentes epidemiologicos permitio detectar y confirmar un brote de fiebre Q, identificar the probable fuente de exposicion and orientar el diagnostico clinico y serologico.
FIEBRE Q. A PROPOSITO DE UN CASO CON LINFOCITOSIS ABSOLUTA
TLDR
El caso de un paciente con fiebre Q acompañado de linfocitosis absoluta, una asociación infrecuente.
Comparison of the new InoDiag automated fluorescence multiplexed antigen microarray to the reference technique in the serodiagnosis of atypical bacterial pneumonia.
TLDR
This preliminary study shows that the automatic InoDiag assay opens the way to immunofluorescence assay standardization.
Immuno-PCR for the early serological diagnosis of acute infectious diseases: the Q fever paradigm
TLDR
iPCR is a promising, sensitive and specific method that can be used for the early diagnosis of acute Q fever and more generally for acute infections where traditional methods lack sensitivity.
Absence of convincing evidence of Coxiella burnetii infection in Chile: a cross-sectional serosurvey among healthy adults in four different regions
TLDR
This work provides the first epidemiological data on human Q fever in Chile indicating either a very low endemicity or the absence of this pathogen in the studied areas.

TLDR
It is suggested that young shedder cows are mostly seronegative in early stages of infection, which would be an indication of severe peripheral blood alterations in some infected cattle.
Prevalence of Coxiella burnetti infection in wild and farmed ungulates.
The application of an enzyme-linked immunosorbent assay or an immunofluorescent assay test leads to different estimates of seroprevalence of Coxiella burnetii in the population
TLDR
It is shown that two commercial assays representing the two methods with two different cut-off titres can lead to significant differences in diagnostic and seroprevalence estimates, emphasizing the need for a standardized gold method to compare the various assays.
Seroepidemiologic survey for Coxiella burnetii among US military personnel deployed to Southwest and Central Asia in 2005.
TLDR
A seroepidemiologic study used to estimate Q fever (Coxiella burnetii) seroprevalence, seroincidence, and risk factors for seroconversion in two deployed military populations in 2005 found no significant risk factors were found in either population.
Occupationally Acquired Q Fever in Shepherds and Sheep Milk Cheesemakers
TLDR
It is shown that Q fever is increasing in sheep farms in Portugal raising alerts on spillover to humans, and anti- C. burnetii IgG is detected in shepherds and sheep milk cheesemakers and in controls, pointing to an increased risk of C. burningetii infection in individuals with occupational contact with sheep in Portugal.

Evaluation of a Novel Commercial Enzyme-Linked Immunosorbent Assay Detecting Coxiella burnetii-Specific Immunoglobulin G for Q Fever Prevaccination Screening and Diagnosis
TLDR
The results presented in this study suggest that the PanBio Q fever IgG ELISA is a specific alternative method for prevaccination testing and an aid for the diagnosis of Q fever.
Comparison of a Commercial Enzyme-Linked Immunosorbent Assay with Immunofluorescence and Complement Fixation Tests for Detection of Coxiella burnetii (Q Fever) Immunoglobulin M
TLDR
Results indicate that the performance of the PanBio C. burnetii (Q fever) IgM ELISA is superior to that of CFT (F = 163), and consequently the ELISA should be a useful aid in the diagnosis of acute Q fever.
Comparison of enzyme-linked immunosorbent assay and complement fixation and indirect fluorescent-antibody tests for detection of Coxiella burnetii antibody
TLDR
An enzyme-linked immunosorbent assay (ELISA) was developed to detect immunoglobulin G to Coxiella burnetii phase II and the high specificity of the three tests was confirmed by analyzing paired serum samples from 36 patients suffering from acute pneumonia of viral or bacterial origin.

Evaluation of specificity of indirect enzyme-linked immunosorbent assay for diagnosis of human Q fever
TLDR
The results suggest that the ELISA is useful for epidemiologic screening and as a diagnostic test for human Q fever.
Q Fever: Queries Remaining after Decades of Research
TLDR
A higher rate of complaints of various pains in Q fever hepatitis patients were observed, including thrombocytopenia as well as elevated sedimentation rate, and incubation of monocytes from patients with Q fever endocarditis demonstrated an increase in the secretion of interleukin 10 (IL-10), which was also increased in patients who had relapsed after treatment of Q feverendocarditis.
Diagnosis of Q Fever
TLDR
The diagnosis of Q fever relies mainly upon serology, the most commonly used method being the immunofluorescence assay, and serological testing for Q fever should always be done for a patient with a febrile illness and negative blood cultures.

TLDR
The clinical and epidemiologic analyses and the number of cases reported permit only an approximation of the true incidence and characteristics of Q fever in Spain.

TLDR
Limited experiments with more purified experimental C. burnetii vaccines have shown that Q fever in cattle may be prevented by vaccination of young uninfected animals only, and herds free of C.Burnetii may be established.
A large outbreak of Q fever in the West Midlands: windborne spread into a metropolitan area?
TLDR
A retrospective computerised analysis showed that the geographical distribution of cases was associated with a source in this area, and the probable cause of the outbreak was windborne spread of coxiella spores from farmland to the conurbation.
