Pangenomic analysis of unveils new traits in genome architecture.

is the etiological agent of Q fever, a worldwide zoonosis able to cause large outbreaks. The disease is polymorphic. Symptomatic primary infection is named acute Q fever and is associated with hepatitis, pneumonia, fever, and auto-immune complications while persistent focalized infections, mainly endocarditis, and vascular infections, occur in a minority of patients but are potentially lethal.

Molecular detection of Coxiella burnetii in aborted bovine fetuses in Brazil.

In the past decade, cases of Q fever have been reported in Brazil. Although the previous report of Coxiella burnetii in humans and animals, the knowledge about the occurrence of this pathogen in livestock in Brazil is scarce. This study aimed to search C.

Coxiella burnetii in slaughterhouses in Brazil: A public health concern.

Q fever is an important zoonosis, yet it is often neglected and can present large outbreaks, as observed in the Netherlands. In the past few years, cases of Q fever have been described in Brazil; however, the epidemiological situation of Q fever in ruminants, the main reservoir of the pathogen, is unknown in this country. Our study aimed to estimate the prevalence of C.

New Genotypes of Circulating in Brazil and Argentina.

, the zoonotic agent of Q fever, has a worldwide distribution. Despite the vast information about the circulating genotypes in Europe and North America, there is a lack of data regarding strains in South America. Here, we show the presence of novel multispacer sequence typing (MST) genotypes of in two clusters detected in Brazil and Argentina that seem to be distant in parenthood.

Molecular typing of Coxiella burnetii from sheep in Egypt.

Coxiella burnetii, the etiological agent of Q fever, is a globally distributed zoonotic disease. The disease was reported serologically in different animal species and humans in Egypt but the genetic information about circulating Coxiella strains is limited. The present study aimed to genetically characterize Coxiella positive samples, identified in abortive sheep, based on a 17-loci Multiple Locus Variable number tandem repeat analysis (MLVA) panel and Multispacer Sequence Typing (MST).
