q fever is an important zoonotic disease caused by infection with coxiella burnetii. limited information is available concerning theseroprevalence of coxiella burnetii in iran.a serological survey was conducted to describe the eroepidemiology of coxiellaburnetii infection in dairy cattle in khorasan razavi province located in northeast of iran. 246 dairy cattle from 19 commercial dairy herds th...

Problem statement: Q fever is a ubiquitous zoonosis caused by Coxiella burnetii, an obligate intracellular rickettsial organism that caused abortion and stillbirth in ruminants. Approach: The prevalence of Coxiella burnetii in Iran is essentially unknown. Its traditional diagnosis is based on culture, serology and conventional PCR. In this present study, for more sensitive and accurate detectio...

One of the largest Q fever outbreaks ever occurred in the Netherlands from 2007-2010, with 25 fatalities among 4,026 notified cases. Airborne dispersion of Coxiella burnetii was suspected but not studied extensively at the time. We investigated temporal and spatial variation of Coxiella burnetii in ambient air at residential locations in the most affected area in the Netherlands (the South-East...

BACKGROUND Q fever is a widespread zoonotic disease caused by Coxiella burnetii. Ticks may act as vectors, and many epidemiological studies aim to assess C. burnetii prevalence in ticks. Because ticks may also be infected with Coxiella-like bacteria, screening tools that differentiate between C. burnetii and Coxiella-like bacteria are essential. METHODS In this study, we screened tick specime...

While shedding routes of Coxiella burnetii are identified, the characteristics of Coxiella shedding are still widely unknown, especially in dairy cattle. However, this information is crucial to assess the natural course of Coxiella burnetii infection within a herd and then to elaborate strategies to limit the risks of transmission between animals and to humans. The present study aimed at (i) de...

Coxiella burnetii is common causative agent of Q fever in humans and animals. Although the main route of human infection is through inhalation of contaminated aerosols (dust), but oral transmission through contaminated raw milk and dairy products are also possible routes of infection. The aim of this study was to identify and determine the extent of contamination and prevalence of Coxiella burn...

Background: Query fever (Q fever), caused by Coxiella burnetii, is a highly infectious zoonotic infection to humans and livestock. Despite extensive efforts develop effective vaccines against this disease, only one vaccine licensed available. The aim of study was investigate the global research trends, keystone bibliometric parameters, network visualization mapping i...

The insertion sequence IS1111 is used formolecular detection of Coxiella burnetii but also found in Coxiella-like endosymbionts of ticks, presenting a risk of false positive detection of C. burnetii. Limited IS1111 sequences from Coxiella-like bacteria restrict in silico assessment of IS1111 assays. However, Coxiella-like bacteria detectable by IS1111 assays appear to be rare in tick population...

The objective of the present investigation was to determine the seroprevalence of Coxiella burnetii infection in free-range yaks in China. A total of 552 serum samples were collected from yaks in Gansu province, northwest China between April 2013 and January 2014, and antibodies against C. burnetii were evaluated using enzyme-linked immunosorbent assay (ELISA). Overall, 13.59% (75/552, 95% CI: ...
