ESAT-6 Peptide Recognition by Bovine CD8 + Lymphocytes of Naturally Infected Cows in Herds from Southern Italy
2006
ABSTRACT The aim of this study was to define epitopes of Mycobacterium bovis from ESAT-6 (early secretory antigen of 6 kDa) recognized by CD8 + T lymphocytes from cows naturally infected with Mycobacterium bovis . We found that bovine CD8 + T cells recognized 10 out of 11 ESAT-6 peptides tested.
Clinical use of BCG and its complications: a case series
2021
Bacillus Calmette-Guérin (BCG), a live, attenuated strain of Mycobacterium bovis, is the essential constituent of the vaccine against tuberculosis and the gold-standard adjuvant treatment for urothelial cancer of the bladder. Being a live, attenuated strain with a potential pathogenic action, bacilli can cause several complications, both locally near the inoculation site and remotely through blood dissemination. BCG-related disease can represent a side effect of anti-TB vaccination in patient with congenital or acquired immunodeficiency or a complication of the therapeutic schedule in oncologic patients. Herein we report five cases of BCG-related disease which occurred at the Infectious Dis…
Prevalence of Mycobacterium bovis in agroecosystems : analysis of potential environmental reservoirs (soil, fresh water, soil fauna and aquatic fauna…

Bovine tuberculosis is an infectious disease caused by Mycobacterium bovis. This disease affects cattle, and many species of domestic and wild mammals, and humans. The circulation of the bacteria in various multi-host systems promotes the maintenance of the disease and the contamination of cattle in the vicinity. Beside direct transmission of the bacteria through the respiratory route, indirect transmission, through inhalation or ingestion of environmental matrices contaminated by an infected animal excretory, is suspected in several countries. Environmental contamination with M. bovis appears to be a crucial factor in the persistence of the infection in multi-host systems.In Côte d'Or, a F…
First morphogenetic analysis of parasite eggs from Schistosomiasis haematobium infected sub-Saharan migrants in Spain and proposal for a new standard…
2021
International audience; Schistosomiasis is a Neglected Tropical Disease caused by trematode species of the genus Schistosoma. Both, autochthonous and imported cases of urogenital schistosomiasis have been described in Europe. The present study focuses on eggs, considered pure S. haematobium by genetic characterisation (intergenic ITS region of the rDNA and cox1 mtDNA). A phenotypic characterisation of S. haematobium eggs was made by morphometric comparison with experimental populations of S. bovis and S. mansoni, to help in the diagnosis of S. haematobium populations infecting sub-Saharan migrants in Spain. Analyses were made by Computer Image Analysis System (CIAS) applied on the basis of …

Non-specific Effects of Vaccines Illustrated Through the BCG Example: From Observations to Demonstrations
2018
Epidemiological studies regarding many successful vaccines suggest that vaccination may lead to a reduction in child mortality and morbidity worldwide, on a grander scale than is attributable to protection against the specific target diseases of these vaccines. These non-specific effects (NSEs) of the Bacille Calmette-Guérin (BCG) vaccine, for instance, implicate adaptive and innate immune mechanisms, with recent evidence suggesting that trained immunity might be a key instrument at play. Collectively referring to the memory-like characteristics of innate immune cells, trained immunity stems from epigenetic reprogramming that these innate immune cells undergo following exposure to a primary…
The role of 18F-FDG PET/CT in early infectious discitis: a case report after a negative MRI
2019
We present the case of a 70 years old woman with infectious discitis which was detected using Fluorine fluodeoxiglucose positron emission tomography/computed tomography (18F-FDG PET/CT), after a negative magnetic resonance imaging. A Streptococuss gallolyticus (bovis gender bacteria) grow on culture. In addition 18F-FDG PET also demonstrated infectious endocarditis which was confirmed by transesophageal echocardiography and a colonic neoplasm. Here we have highlighted the potential role of 18F-FDG PET/CT study in patients with a clinical history suggestive of infectious discitis with a negative or indifferent magnetic resonance imaging. Keywords: 18F-FDG PET/TC, Spondylodiscitis, Pyogenic v…

Phenotypic and genetic characterization of emerging trematodiasis: Fascioliasis and Schistosomiasis
2021
La Fascioliasis y la Esquistosomiasis son dos importantes trematodiasis (re)emergentes con gran impacto en la salud humana. Dada la necesidad de caracterizar las poblaciones de Trematodos involucradas, los objetivos de la presente investigación son: en primer lugar, analizar el impacto de la reinfección experimental por Fasciola hepatica en los fenotipos inmunológicos, clínicos y biológicos por medio de un diseño experimental que reproduce las condiciones habituales de reinfección/cronicidad en las zonas endémicas de la Fascioliasis humana; en segundo lugar, la caracterización fenotípica morfológica de huevos de Schistosoma haematobium de migrantes subsaharianos con Esquistosomiasis urogeni…
