The cellular immune response to tissue damage and infection requires the recruitment of blood leukocytes. This process is mediated through a classical multistep mechanism, which involves transient rolling on the endothelium and recognition of inflammation followed by extravasation. We have shown, by direct examination of blood monocyte functions in vivo,(More)
The coordinated migration and maturation of dendritic cells (DCs) such as intraepithelial Langerhans cells (LCs) is considered critical for T cell priming in response to inflammation in the periphery. However, little is known about the role of inflammatory mediators for LC maturation and recruitment to lymph nodes in vivo. Here we show in human(More)
The clinical phenotype of interleukin 12 receptor ␤ 1 chain (IL-12R ␤ 1) deficiency and the function of human IL-12 in host defense remain largely unknown, due to the small number of patients reported. We now report 41 patients with complete IL-12R ␤ 1 deficiency from 17 countries. The only opportunistic infections observed, in 34 patients, were of(More)
BACKGROUND Corynebacterium pseudotuberculosis is generally regarded as an important animal pathogen that rarely infects humans. Clinical strains are occasionally recovered from human cases of lymphadenitis, such as C. pseudotuberculosis FRC41 that was isolated from the inguinal lymph node of a 12-year-old girl with necrotizing lymphadenitis. To detect(More)
To investigate interactions between the endothelium and leukocytes in patients with sepsis, we measured soluble adhesion molecules (sE-selectin and sICAM-1), von Willebrand factor antigen (vWf:Ag), myeloperoxidase (MPO), and lactoferrin (Lacto-f) as plasma markers of endothelial and neutrophil activation. We tested whether the five proteins were predictors(More)
Here, we announce the complete annotated genome sequence of a Streptococcus pyogenes M/emm83 strain, STAB1101, isolated from clustered cases in homeless persons in Brittany (France). The genome is composed of 1,709,790 bp, with a G+C content of 38.4% and 1,550 identified coding sequences (CDS), and it harbors a Tn916-like transposon.
We report a closed genome sequence of group A Streptococcus genotype emm3 (GAS M/emm3) strain STAB902, isolated from a superficial pyodermatitis. The genome is composed of 1,892,124 bp, 6 integrated prophages, and has 1,858 identified coding sequences (CDSs). It has been fitted with the two available invasive GAS M/emm3 strains.
Here, we announce the complete annotated genome sequence of the invasive Streptococcus pyogenes strain M/emm66, isolated in 2013 from a subcutaneous abscess in new clustered cases in French Brittany.
We report 2 cases of pulmonary Bordetella hinzii infection in immunodeficient patients. One of these rare cases demonstrated the potential transmission of the bacteria from an avian reservoir through occupational exposure and its persistence in humans. We establish bacteriologic management of these infections and suggest therapeutic options if needed.
We report here the complete genome sequence of a noninvasive strain of Streptococcus pyogenes M/emm28, isolated from perianal dermatitis in a child. The genome is composed of 1,950,454 bp, with a G+C content of 38.2%, and it has 1,925 identified coding sequences and harbors two intact prophages and a new integrating conjugative element (ICE).
