Journal ArticleDOI
Emergence of Salmonella epidemics: the problems related to Salmonella enterica serotype Enteritidis and multiple antibiotic resistance in other major serotypes.
TL;DR: This review updates information on the S. Enteritidis pandemic and focuses on the emergence of Salmonella, carrying the SGI1 antibiotic resistance gene cluster, resistant to extended-spectrum cephalosporins, or resistant to fluoroquinolones.
Journal ArticleDOI
Ability of Bacillus cereus Group Strains To Cause Food Poisoning Varies According to Phylogenetic Affiliation (Groups I to VII) Rather than Species Affiliation
Marie-Hélène Guinebretière,Marie-Hélène Guinebretière,Philippe Velge,Olivier Couvert,Frédéric Carlin,Frédéric Carlin,Marie-Laure Debuyser,Christophe Nguyen-The,Christophe Nguyen-The +8 more
TL;DR: Cytotoxic activity levels of culture filtrates and toxin distributions varied according to the phylogenetic group (I to VII) within the B acillus cereus group, suggesting that these groups are of different clinical significance and are more suitable than species affiliations for determining food poisoning risk.
Journal ArticleDOI
Vaccination and early protection against non-host-specific Salmonella serotypes in poultry: exploitation of innate immunity and microbial activity
F. Van Immerseel,Ulrich Methner,Ivan Rychlik,Béla Nagy,Philippe Velge,G. Martin,Neil Foster,Richard Ducatelle,Paul A. Barrow +8 more
TL;DR: It is recommended that all live vaccines considered for oral administration should be tested for their ability to induce the two protective effects described above, including specific colonization-inhibition (competitive exclusion) in which the protective bacteria exert a profound resistance to establishment and colonization by other related bacteria.
Journal ArticleDOI
Prevalence, characterization and growth of Bacillus cereus in commercial cooked chilled foods containing vegetables
C. Choma,C. Choma,Marie-Hélène Guinebretière,Frédéric Carlin,Philippe Schmitt,Philippe Velge,Per Einar Granum,Christophe Nguyen-The +7 more
TL;DR: B. cereus strains unable to degrade starch, a feature linked to the production of emetic toxin, did not grow at 10 °C and had a higher heat resistance at 90’°C.
Journal ArticleDOI
Multiplicity of Salmonella entry mechanisms, a new paradigm for Salmonella pathogenesis.

TL;DR: The different entry pathways used by Salmonella serotypes to enter different nonphagocytic cell types are described and the first bacterium shown to be able to induce both Zipper and Trigger mechanisms to invade host cells is shown.
