11. Antibacterial peptides - key players in host defense at epithelial surfaces
Abstract : Innate host defense mechanisms at epithelial surfaces are important to prevent bacterial invasion. Streptococcus pyogenes, group A streptococcus (GAS), has an affinity for epithelial cells and cause pharyngitis. During streptococcal pharyngitis, high concentrations of the chemokines CXCL9/MIG, CXCL10/IP-10, CXCL11/I-TAC were found in tonsil fluid. READ MORE

12. Insect immunity : Inducible antibacterial proteins from Hyalophora cecropia
Abstract : A powerful bactericidal activity can be induced in the hemolymph of many insects as a response to an injection of bacteria. The nature of the effector molecules of this immune response was investigated, using pupae of the Cecropia moth, Hyalophora cecropia. READ MORE

13. Bioactive Surgical Implant Coatings with Optional Antibacterial Function
Abstract : Device associated infections are a growing problem in the field of orthopaedics and dentistry. Bacteria adhering to implant surfaces and subsequent biofilm formation are challenging to treat with systemic administered antibiotics. READ MORE

14. Studies on bacteria resistant and susceptible to humoral immunity in insects
Abstract : Insects have developed several defense mechanisms against microorganismsi The injection of live bacteria into Lepidoptera pupae induces the synthesis of several bactericidal proteins, especially the cecropins and the attacins. Important properties of an insect pathogenic bacterium are invasiveness and resistance to immunity. READ MORE

15. Insect immunity : fractionation and characterization of some immune proteins induced by primary infections of giant silk moth pupae
Abstract : A potent antibacterial activity in hemolymph of giant silk moth pupae is demonstrated. The system is inducible and RNA and protein synthesis are needed for the expression of the activity. Both Gram-positive and Gram-negative bacteria were found to be susceptible. The activities could be selectively inhibited, indicating a multicomponent system. READ MORE
