Nicholas J Clark, Ricardo J Soares Magalhães
BACKGROUND: Q fever is a zoonotic disease caused by Coxiella burnetii. This bacterium survives harsh conditions and attaches to dust, suggesting environmental dispersal is a risk factor for outbreaks. Spatial epidemiology studies collating evidence on Q fever geographical contamination gradients are needed, as human cases without occupational exposure are increasing worldwide. METHODS: We used a systematic literature search to assess the role of distance from ruminant holdings as a risk factor for human Q fever outbreaks...

REVIEW
Domenico Plantone, Tatiana Koudriavtseva
The process of finding new therapeutic indications for currently used drugs, defined as 'repurposing', is receiving growing attention. Chloroquine and hydroxychloroquine, with an original indication to prevent or cure malaria, have been successfully used to treat several infectious (HIV, Q fever, Whipple's disease, fungal infections), rheumatological (systemic lupus erythematosus, antiphospholipid antibody syndrome, rheumatoid arthritis, Sjögren's syndrome), and other immunological diseases. Indeed, they have anti-inflammatory, immunomodulating, anti-infective, antithrombotic, and metabolic effects...

INTRODUCTION: Adult-onset Still's Disease is a rare multisystemic inflammatory disease characterized by fever, maculo-papular erythematous rash and arthralgia. Adult-onset Still's disease is a diagnosis of exclusion. CASE REPORT: We report the case of a 33 years old man, hospitalized for fever, arthralgia and throat manifestations, leading to Adult-onset Stills's Disease diagnosis. Cardiac ultrasound revealed tricuspid vegetation. Once infectious causes were ruled out, the vegetation was related to Adult-onset Still's Disease according to Fautrel and Yamaguchi criteria...

The  Coxiella burnetii strain NL3262 was isolated during the Q fever outbreak in the Netherlands in 2007-2010. Formal-order analysis (FOA) was used to study the similarity of the genome (chromosome and plasmid) of this strain with the genomes from other strains. Chromosomes from ten C. burnetii strains and eight plasmids were studied with FOA tools such as 'Map of genes' and 'Matrix of similarity.' The 'Map of genes' tool showed that the chromosome of strain C. burnetii str. NL3262 distanced itself by the index of average remoteness ( g ) of 1...

OBJECTIVE: After primary infection with Coxiella burnetii, patients may develop acute Q fever, which is a relatively mild disease. A small proportion of patients (1%-5%) develop chronic Q fever, which is accompanied by high mortality and can be manifested as infected arterial or aortic aneurysms or infected vascular prostheses. The disease can be complicated by arterial fistulas, which are often fatal if they are left untreated. We aimed to assess the cumulative incidence of arterial fistulas and mortality in patients with proven chronic Q fever...

Q fever is a zoonotic disease caused by Coxiella burnetii that usually presents with non-specific or benign constitutional symptoms. Diagnosis is often challenging and, after acute Q fever, 1%-5% of patients can develop chronic disease. We present an 80-year-old male patient who was admitted due to a 3 months history of fever, productive cough, myalgia, weight loss, headache and hearing loss. Chronic Q fever was confirmed by positive antiphase I immunoglobulin G. Frequent locations of chronic infection was discarded, and ear CT revealed a right mastoid infection...

A better understanding of veterinary students’ perceptions, attitudes, and knowledge about antimicrobial stewardship and biosecurity could facilitate more effective education of future veterinarians about these important issues. A multicenter cross-sectional study was performed by administering a questionnaire to veterinary students expected to graduate in 2017 or 2018 in all Australian veterinary schools. Four hundred and seventy-six of 1246 students (38%) completed the survey. Many students were unaware of the high importance of some veterinary drugs to human medicine, specifically enrofloxacin and cefovecin (59% and 47% of responses, respectively)...

A lack of surveillance and diagnostics for zoonotic diseases in rural human clinics limits clinical awareness of these diseases. We assessed the prevalence of nine zoonotic pathogens in a pastoral, low-income, HIV-endemic community bordering wildlife reserves in South Africa. Two groups of participants were included: malaria-negative acute febrile illness (AFI) patients, called febrilers, at three clinics (n = 74) and second, farmers, herders, and veterinary staff found at five government cattle dip-tanks, called dip-tanksters (n = 64)...

BACKGROUND: Many gram-negative bacteria produce an outer membrane phospholipase A (PldA) that plays an important role in outer membrane function and is associated with virulence. RESULTS: In the current study, we characterized a pldA mutant of Coxiella burnetii, an intracellular gram-negative pathogen and the agent of human Q fever. The C. burnetti pldA open reading frame directs synthesis of a protein with conserved PldA active site residues. A C. burnetii ΔpldA deletion mutant had a significant growth defect in THP-1 macrophages, but not axenic medium, that was rescued by complementation...

BACKGROUND: An association between Coxiella burnetii and non-Hodgkin lymphoma has been suggested. After a large Q fever epidemic in the Netherlands (2007-10), we postulated that the incidence of non-Hodgkin lymphoma would be increased during and after the epidemic in areas with a high endemicity of Q fever compared with those with low endemicity. METHODS: We did a retrospective population-based analysis and calculated relative risks (RRs) of non-Hodgkin lymphoma during 1-year periods before, during, and after the Q fever epidemic, for areas with intermediate and high endemicity of Q fever compared with low endemic areas...
