bovine mastitis. The aim of the present work was to follow in three herds and during the 3 years the clonality of S. aureus isolated from California Mastitis Test (CMT)-positive cows at the experimental station of Toukounous (Niger) by (i) comparing their pulsed field gel electrophoresis (PFGE) fingerprints, (ii) identifying their virulotypes by PCR amplification and (iii) assessing the production of capsule and the formation of biofilm. The 88 S. aureus isolates belonged to 14 different pulsotypes, 3 of them being predominant: A (30 %), D (27 %), B (15 %). A and B pulsotypes had the highest profile similarity coefficient (94 %), while others had similarity coefficients under 60 %. Seventy-five S. aureus isolates were further studied for their virulotypes, capsular antigens and biofilm production. Most surface factor-, leukocidin- and haemolysin-, but not the enterotoxin-encoding genes were detected in the majority (>75 %) of the isolates and were evenly distributed between the A, B and D pulsotype isolates. The majority of the 72 S. aureus positive with the cap5H or cap8H PCR produced the CP5 (82 %) or the CP8 (88 %) capsular antigen, respectively. Biofilm production by the 57 icaA-positive isolates was strong for 8 isolates, moderate for 31 isolates but weak for 18 isolates, implying that the icaA gene may not be expressed in vitro by one third of the positive isolates. Similar to other studies, those results confirm that a restricted number of S. aureus clones circulate within the three herds at Toukounous and that their specific virulence-associated properties must still be further studied [less ▲]

Understanding the molecular parameters that regulate cross-species transmission and host adaptation of potential pathogens is crucial to control emerging infectious disease. Although microbial pathotype diversity is conventionally associated with gene gain or loss, the role of pathoadaptive nonsynonymous single-nucleotide polymorphisms (nsSNPs) has not been systematically evaluated. Here, our genome-wide analysis of core genes within Salmonella enterica serovar Typhimurium genomes reveals a high degree of allelic variation in surface-exposed molecules, including adhesins that promote host colonization. Subsequent multinomial logistic regression, MultiPhen and Random Forest analyses of known/suspected adhesins from 580 independent Typhimurium isolates identifies distinct host-specific nsSNP signatures. Moreover, population and functional analyses of host-associated nsSNPs for FimH, the type 1 fimbrial adhesin, highlights the role of key allelic residues in host-specific adherence in vitro. Together, our data provide the first concrete evidence that functional differences between allelic variants of bacterial proteins likely contribute to pathoadaption to diverse hosts. [less ▲]

La contribution de l'élevage est essentielle pour l'amélioration de la production alimentaire et la réduction de la pauvreté dans le Sahel. Dans ce vaste ensemble, l’élevage repose sur l’exploitation des parcours naturels avec différents système de production. Ainsi, on retrouve principalement trois types de système à savoir le type pastoral, le type nomade, le type transhumant auxquels s’ajoute le système de ranching. Les races bovines sahéliennes sont caractérisées par des faibles productions avec des paramètres de reproduction peu performants. Certains pays sahélien ont adopté plusieurs politiques d’amélioration des productions des races locales à travers notamment l’insémination artificielle ou encore la mise en place de programme de sélection de race locale performante. C’est ainsi que, le zébu azawak élevé dans un système de ranching à Toukounous (Niger) s’est révélé bien adapté dans un système de production aride avec des productions animales nettement supérieurs aux autres races rencontrées. Cet article décrit les modes d’élevage dans le Sahel, les principales races bovines rencontrées et enfin traite des avantages comparatifs qu’offre la race azawak par rapport aux autres races bovines locales et aux produits issus du croisement de l’insémination artificielle.
