Characterization of Anaplasma phagocytophilum major surface protein 5 and the extent of its cross-reactivity with A. marginale

Major surface protein 5 (Msp5) of Anaplasma marginale is highly conserved in the genus Anaplasma and the antigen used in a commercially available competitive enzyme-linked immunosorbent assay (cELISA) for serologic identification of cattle with anaplasmosis. This study analyzes the degrees of conservation of Msp5 among various isolates of Anaplasma phagocytophilum and the extent of serologic cross-reactivity between recombinant Msp5 (rMsp5) of Anaplasma marginale and A. phagocytophilum. The msp5 genes from various isolates of A. phagocytophilum were sequenced and compared. rMsp5 proteins of A. phagocytophilum and A. marginale were used separately in an indirect ELISA to detect cross-reactivity in serum samples from humans and dogs infected with A. phagocytophilum and cattle infected with A. marginale. Serum samples were also tested with a commercially available competitive ELISA that uses monoclonal antibody ANAF16C1. There were 100% sequence identities in the msp5 genes among all of the A. phagocytophilum isolates from the United States and a horse isolate from Sweden. Sheep isolates from Norway and dog isolates from Sweden were 99% identical to one another but differed in 17 base pairs from the United States isolates and the horse isolate. Serologic cross-reactivity was identified when serum samples from cattle infected with A. marginale were reacted with rMsp5 of A. phagocytophilum and when serum samples from humans and dogs infected with A. phagocytophilum were reacted with rMsp5 of A. marginale in an indirect-ELISA format. Serum samples from dogs or humans infected with A. phagocytophilum did not cross-react with rMsp5 of A. marginale when tested with the commercially available cELISA. These results suggest that rMsp5 of A. phagocytophilum is highly conserved among United States and European isolates and that serologic distinction between A. phagocytophilum and A. marginale infections cannot be accomplished if rMsp5 from either organism is used in an indirect ELISA.

Posterior approaches to the acetabulum

Posterior approaches to the hip joint were developed by Langenbeck and Kocher in the nineteenth century. Letournel created the term Kocher-Langenbeck approach which became one of the most important approaches to the hip joint. The further extension of this approach by digastric trochanteric osteotomy and subsequently by surgical hip dislocation enables visualization of the entire hip joint which allows complete evaluation of articular joint damage, quality of reduction and confirmation of extra-articular hardware. With the increasing incidence of acetabular fractures in the elderly there is a concomitant increase of complicating factors, such as multifragmentary posterior wall fractures, dome impaction, marginal impaction and femoral head damage. These factors are negative predictors and compromise a favorable outcome after acetabular surgery. With direct joint visualization these factors can be reliably recognized and corrected as adequately as possible. Surgical hip dislocation thus offers advantages in complex posterior wall, transverse and T-shaped fractures with or without posterior wall involvement. For these fracture types surgical hip dislocation represents a standard approach in our hands.

Tableaux de la lande et autres poèmes, traduit par Patrick Suter en collaboration avec Bernard Böschenstein

Annette von Droste-Hülshoff, «die grösste deutsche Dichterin», comme on le dit fréquemment en allemand, a longtemps passé pour intraduisible. Ces traductions essaient pour la première fois de respecter la densité des vers allemands, tant sur les plans phonique que sémantique.

Frontières - théâtre-essai

Certes la distinction tranchée entre tragédie et comédie n’a plus cours, par contre si vous essayez de ronger les frontières entre essai, roman, théâtre, poésie, quel tollé», écrivait Michel Butor. Pour représenter la multiplicité des frontières, il a pourtant été nécessaire dans ce livre de convoquer une écriture située elle-même aux frontières des genres, polyphonique, procédant par montage et rapprochements de voix éparses, selon un principe de choralité. En est né un genre hybride, le «théâtre-essai» (à la façon dont certains vidéastes pratiquent le «vidéo-essai»). En tant qu’essai, ce livre repose sur une base documentaire, qui a porté d’une part sur la figuration des frontières en littérature et dans les arts, d’autre part sur les approches des frontières par les différents domaines du savoir (géographie, droit, polémologie, sociologie, anthropologie et écologie). Mais c’est à travers le langage théâtral lui-même, tant sur le plan textuel que de l’organisation de l’espace, que les frontières sont ici interrogées : celles qui séparent le littéraire du non-littéraire, ou la salle de la scène.

Die Triosonate in Spanien: die Konsequenzen musikalischer Mobilität

Die Triosonate hatte in Spanien nur eine marginale Präsenz. Fast ausnahmslos wurde die Gattung von ausländischen Komponisten und Musikern an Adelshöfe oder dem Königshof gepflegt. Diese nahmen aber ihre Umgebung und deren musikalische Impulse auf.
