Specific interaction between Group B Streptococcus CC17 hypervirulent clone and phagocytes

A.-S. Bourrel, A. Picart, J.-C. Fernandez, C. Hays, B. Saubamea, V. Mignon, C. Poyart, A. Tazi, J. Guignot

This study investigates how the hypervirulent GBS CC17 strain interacts with macrophages, showing it is phagocytosed more efficiently due to specific surface proteins and scavenger receptor inhibition.

Streptococcus pyogenes infects human endometrium by limiting its immune response

A. Weckel, T. Guilbert, C. Lambert, C. Plainvert, F. Goffinet, C. Poyart, C. Mehats, A. Fouet

This study shows how Streptococcus pyogenes infects human endometrium by using tissue products to multiply and impairing the immune response through protease and toxin activities.

Permissive Fatty Acid Incorporation in Host Environments Promotes Staphylococcal Adaptation to FASII Antibiotics

G. Kenanian, C. Morvan, A. Weckel, A. Pathania, J. Anba-Mondoloni, D. Halpern, A. Solgadi, L. Dupont, C. Henry, C. Poyart, A. Fouet, G. Lamberet, K. Gloux, A. Gruss

This study shows that Staphylococcus aureus can adapt to FASII antibiotics by incorporating environmental fatty acids in host conditions, challenging the assumption of fatty acid stringency.
