Denitrification in pathogenic bacteria : for better or worst ?
2005
A large variety of physiological and taxonomic groups have the ability to use nitrogen oxides as alternative electron acceptors. Brucella spp. is an alpha-proteobacteriaceae that induces a persistent disease in some mammals. Recent work has revealed that a denitrifying gene cluster is important in the interaction of Brucella neotomoae with its host.
A case of Brucella endocarditis in association with subclavian artery thrombosis.
2012
Brucellosis is a common zoonosis, endemic in Mediterranean countries, and caused by bacteria ofBrucellagenus. Brucellosis is a systemic infection and the clinical presentation varies widely from asymptomatic and mild to severe disease. Cardiovascular complications are extremely rare. We present a case of arterial thrombosis in a previously healthy young patient withBrucellaendocarditis. Careful attention must be paid to any sign or symptom of thrombosis in patients affected by brucellosis, regardless of the presence of endocarditis and cardiovascular risk factors.
Urticaria and bacterial infections
2014
The association between urticaria and infectious diseases has been discussed for >100 years. However, a causal relationship with underlying or precipitating infection is difficult to establish. The purpose of this work was to perform a systematic analysis of the published cases of urticaria associated with bacterial infections. We give an umbrella breakdown of up-to-date systematic reviews and other important publications on the complex association of urticaria and bacterial infections. We did a Medline search, for English language articles published until January 2014, using the key words "urticaria" and "bacteria/bacterial disease"; a second analysis was performed in groups of bacteria an…

Involvement of the aorta in brucellosis: the forgotten, life-threatening complication. A systematic review.
2012
Abstract Human brucellosis is a disease of protean manifestations, and has been implicated in complications and focal disease in many human organ systems. However, little is collectively known about the background, the course, the clinical characteristics, the diagnostic issues raised, and the short- and long-term therapeutic approaches in patients with aortic involvement as a complication of brucellosis. With the aim to glean from the literature useful information to better understand and manage this complication, a computerized search without language restriction was conducted using PubMed and SCOPUS. An article was considered eligible for inclusion in the systematic review if it reported…
GTPases of the Rho Subfamily Are Required for Brucella abortus Internalization in Nonprofessional Phagocytes
2001
Members of the genus Brucella are intracellular -Proteobacteria responsible for brucellosis, a chronic disease of humans and animals. Little is known about Brucella virulence mechanisms, but the abilities of these bacteria to invade and to survive within cells are decisive factors for causing disease. Transmission electron and fluorescence microscopy of infected nonprofessional phagocytic HeLa cells revealed minor membrane changes accompanied by discrete recruitment of F-actin at the site of Brucella abortus entry. Cell uptake of B. abortus was negatively affected to various degrees by actin, actin-myosin, and microtubule chemical inhibitors. Modulators of MAPKs and protein-tyrosine kinases…
Endovascular Repair of Aortic Rupture Due to Brucella Aortitis. Case report and Review of the literature. VASA 2011;40:150-6. PMID:21500181
2011
Brucellosis is a zoonosis, caused by bacteria belonging to the genus Brucella. Aortic involvement is a rare complication, often following embolization from infective endocarditis. However, contiguous propagation from vertebral involvement may occur. We report the case of an 81 year old patient abruptly presenting with aortic rupture due to Brucella melitensis infection. The diagnosis of aortic rupture was made by CT. The patient underwent urgent endovascular treatment using endoprosthesis deployment in the abdominal aorta and iliac arteries. Long term antibiotic treatment was given. Resolution of the acute event was obtained without further surgical treatment. 18 months after endovascular t…
