Endocardite por Coxiella burnetii (febre Q): doença rara ou pouco diagnosticada? Relato de caso Endocarditis due to Coxiella burnetii (Q fever): a rare or underdiagnosed disease? Case report [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 2008
A febre Q é uma zoonose de distribuição mundial causada por Coxiella burnetii, sendo raros os registros da doença no Brasil. Estudos soroepidemiológicos mostraram uma freqüência relativamente elevada de anticorpos contra Coxiella burnetii em populações ...

Candidatus Coxiella massiliensis Infection

Emerging Infectious Diseases, 2016
Bacteria genetically related to Coxiella burnetii have been found in ticks. Using molecular techniques, we detected Coxiella-like bacteria, here named Candidatus Coxiella massiliensis, in skin biopsy samples and ticks removed from patients with an eschar.

Coxiella burnetii and Leishmania mexicana residing within similar parasitophorous vacuoles elicit disparate host responses [PDF]

Frontiers in Microbiology, 2015
Coxiella burnetii is a bacterium that thrives in an acidic parasitophorous vacuole (PV) derived from lysosomes. Leishmania mexicana, a eukaryote, has also independently evolved to live in a morphologically similar PV.

Detection of Multiple Microorganisms in Ruminant Ticks in Senegal Using High-Throughput Microfluidic Real-Time PCR. [PDF]

Transbound Emerg Dis
Ticks are major vectors of numerous pathogens affecting both livestock and humans. In Senegal, data on the diversity of tick‐borne pathogens (TBPs) in ruminant‐associated ticks remain limited. In total, 1703 ticks were collected from goats, sheep, and cattle across three ecological zones of Senegal (Sudanian, Sahelian, and Sudano‐Sahelian).

Molecular and Serological Detection of Coxiella burnetii in Small Ruminants in Northeastern Brazil. [PDF]

Vet Med Sci
• Serology indicates that one‐third of the sheep and goats had previously been infected with Coxiella burnetii. • qPCR analysis revealed the ongoing presence of C. burnetii in all evaluated flocks, each with a previous history of reproductive disorders. • These results indicate the need for preventive measures and control of C.

Investigation of Coxiella burnetii distribution in a Scottish dairy cattle herd with history of stillbirths. [PDF]

Vet Rec
Abstract Background Coxiella burnetii is a bacterial pathogen that can cause abortion and reproductive disease in livestock. In the UK, C. burnetii affects many dairy cattle herds, although the infection dynamics are poorly understood. Our study was performed to investigate infection patterns within a dairy cattle herd in Scotland that had experienced ...

Identification of OmpA, a Coxiella burnetii protein involved in host cell invasion, by multi-phenotypic high-content screening. [PDF]

PLoS Pathogens, 2014
Coxiella burnetii is the agent of the emerging zoonosis Q fever. This pathogen invades phagocytic and non-phagocytic cells and uses a Dot/Icm secretion system to co-opt the endocytic pathway for the biogenesis of an acidic parasitophorous vacuole where ...

Phylogeography of Human and Animal Coxiella burnetii Strains: Genetic Fingerprinting of Q Fever in Belgium

Frontiers in Cellular and Infection Microbiology, 2021
Q fever is a zoonotic disease caused by the bacteria Coxiella burnetii. Domestic ruminants are the primary source for human infection, and the identification of likely contamination routes from the reservoir animals the critical point to implement ...

A Coxiella burnetii phospholipase A homolog pldA is required for optimal growth in macrophages and developmental form lipid remodeling

BMC Microbiology, 2018
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.
