Chronic inflammation of the lung, as a consequence of persistent bacterial infections by several opportunistic pathogens represents the main cause of mortality and morbidity in cystic fibrosis (CF) patients. Mechanisms leading to increased susceptibility to bacterial infections in CF are not completely known, although the involvement of cystic fibrosis(More)
Bovine tuberculosis (bTB) is an emerging disease among wild animals in many parts of the world. Wildlife reservoir hosts may thus represent a potential source of infection for livestock and humans. We investigated the role played by the Sicilian black pig, an autochthonous free- or semi-free-ranging domestic pig breed, as a potential source of bTB infection(More)
The importance of probiotics in human nutrition has been gaining recognition in recent years. These organisms have been shown to promote human health by enhancing immunological and digestive functions and fighting respiratory tract infections. We propose an improved in vitro model for the study of probiotic antimicrobial activity against enteropathogens, by(More)
Acute aortic dissection (AAD) is a life-threatening disease with an incidence of about 2.6-3.6 cases per 100,000/year. Depending on the site of rupture, AAD is classified as Stanford-A when the ascending aortic thoracic tract and/or the arch are involved, and Stanford-B when the descending thoracic aorta and/or aortic abdominal tract are targeted. It was(More)
The present report describes a rare case of generalized bovine-type tuberculosis in a slaughtered 4-year-old ewe discovered during routine surveillance at an abattoir. A postmortem examination revealed lesions in the ewe's thoracic and abdominal cavities, ranging from encapsulated, mineralized foci to extensive, soft, caseous tissue. Lesions in the lungs,(More)
BACKGROUND Atherosclerosis is a multifactorial disease characterized by an immune-inflammatory remodeling of the arterial wall. Treg and Th17 subpopulations are detectable inside atherosclerotic plaque; however, their behavior in symptomatic carotid artery stenosis (CAS) is not fully elucidated. The aim of this study was to evaluate Th17 and Treg subsets(More)
Among polymeric polycations, chitosan has emerged as a powerful carrier for gene delivery. Only a few studies have focused on the stability of the chitosan/DNA complex under storage, although this is imperative for nanomedicinal applications. Here, we synthesized polyelectrolyte complexes at a charge ratio of 10 using 50 kDa chitosan and plasmid (p)DNA that(More)
BACKGROUND The study evaluated macrophage cytokines and macrophage metalloprotease (MMP)-12 levels in patients with Stanford-A acute aortic dissection (AAD) and in patients with critical carotid artery stenosis (CAS) compared with patients matched for age, sex, and traditional cardiovascular risk factors (RF). The aim was to identify possible early serum(More)
Burkholderia cenocepacia is an important human pathogen in patients with cystic fibrosis (CF). Non-clinical reservoirs may play a role in the acquisition of infection, so it is important to evaluate the pathogenic potential of environmental B. cenocepacia isolates. In this study, we investigated the interactions of two environmental B. cenocepacia strains(More)
Pseudomonas aeruginosa is the most common pathogen for chronic lung infection in cystic fibrosis (CF) patients. About 80% of adult CF patients have chronic P. aeruginosa infection, which accounts for much of the morbidity and most of the mortality. Both bacterial genetic adaptations and defective innate immune responses contribute to the bacteria(More)
