Abstract Urban outbreaks of Q fever have occurred after exposure to slaughterhouses or parturient cats. We detected an outbreak of Q fever in a homeless shelter in Marseilles. Investigations showed that the main factors exposing persons to Coxiella burnetii were an abandoned slaughterhouse used for an annual Muslim sheep feast and wind.

Q fever is an acute febrile illness due to Coxiella burnetii. In the Balkans, Q fever in humans has been reported since World War II, and in countries such as Bulgaria the number of cases has increased since the early 1990s. We report an investigation of an outbreak in the town of Botevgrad, Western Bulgaria. Overall, 220 cases were identified between May 1 and June 9, 2004. Of the cases, 168 were from Botevgrad; the others were from neighbouring towns. This has been the largest outbreak in Bulgaria in the last 20 years. Q fever outbreaks in urban areas are not common. Flocks of sheep and goats were the most likely source of infection, as suggested by the observation that flocks grazed in, or had travelled on, the roads and the gardens of the town, and for the prevalence of anti-C. burnetii antibodies among animals in the area. This large outbreak highlights how zoonoses such as Q fever may represent a public-health threat also for urban populations.

Soluble antigen obtained by the treatment of Coxiella burneti of the I phase with trichloracetic acid could be used in the capacity of a precipitinogen in the band-precipitation reaction in the diagnosis of Q-rickettsiosis and in mass epidemiological studies.

Q fever, a rickettsial infection seen worldwide, is caused by Coxiella burnetii. Most outbreaks occur in rural areas and are associated with exposure to animals or their excreta. Now, researchers describe a large outbreak of this illness at a religious boarding school in Tel …

Rickettsioses are infectious diseases transmitted to human by arthropodes, characterized by different clinical manifestation, from subclinical symptoms, through the mild virus-like infection to severe disease with multiorgan complications. Rickettsiosis include typhus, spotted fevers, anaplasmosis, bartonellosis and Q fever. In some of these diseases respiratory symptoms predominate (i.e. acute Q fever), where as one do not occure in the others at all. Rickettsiosis treatment is based usually on the use of tetracycline antibiotics.

Q fever is known to be a worldwide disease, with Sweden supposed to be one of a few exceptions. The purpose of this pilot study was to elucidate whether or not a potential risk group for obtaining Q fever in Sweden was seropositive to the causative agent Coxiella burnetii. Blood samples were collected from sheep farmers on the island of Gotland, and from members of their families. Serum samples were examined by ELISA for the presence of antibodies against C. burnetii, phases I and II. Positive reactions were confirmed with Western blot analysis. It was found that 30% of the study group were seropositive to C. burnetii, thus indicating that Q fever is endemic in this area of Sweden.

Q fever (Query Fever) is a zoonosis caused by the rickettsia Coxiella burnetii. domestic ungulates such as sheep, cattle, and goats serve as the reservoir of infection for humans and shed the desiccation-resistant organism in urine, feces, milk, and especially in birth products. In humans the illness is generally mild; however, Q fever hepatitis is often seen and Q fever endocarditis is an uncommon, but frequently fatal complication. Q fever long has been recognized as an occupational hazard among persons working with animals or animal products, and in laboratories working with C. burnetii. Recently, Q fever outbreaks have occurred in medical research facilities using sheep as research animals. Recommendations are presented for reducing the risk of exposure to Q fever in persons not working with sheep in research facilities that use sheep. In addition, recommendations are presented for reducing the risk of infection in persons who work with sheep in research facilities.
