    Summary:Recently, Zinc-doped hydroxyapatite (Zn-HAp) nanoparticles have been developed aiming at an antibacterial-coating nanomaterial. In this study, Zn-HAp coated non-woven poly(L-lactic acid)(PLLA) fabrics were prepared and evaluated the antibacterial activity for the fabric to improve the reproducibility of the activity instead of the coated sheet. The dispersed Zn-HAp nanoparticles were prepared by a wet chemical method and calcined by an anti-sintering method. The Zn-HAp were coated on the PLLA fabric treated by an alkali solution. The antibacterial evaluation was carried out by contacting the coated fabric with E. coli. suspension. The Zn-HAp nanoparticles (12.5% of Zn-substitution ratio) were obtained and almost uniformly coated on a PLLA fabric through ionic interaction, showing approximately 80% of the surface coverage ratio. The antibacterial activity of the Zn-HAp-coated fabric was significantly higher than that of the non-coated one. Therefore, it was thought that increasing the contact area against the bacteria was effective for the evaluation.

    Summary:Zika virus (ZIKV) is transmitted by Aedes aegypti, and has an aspect of STD pathogen. Its intrauterine infection causes microcephaly. Envelope (E) protein induces protective immunity. The mucosa is the front - line to foreign substances and microorganisms, and a mucosal immune tissue called mucosal - associated lymphoid tissue (MALT) exists. Therefore, immunization onto the gastrointestinal mucosa is expected to induce strong mucosal immunity with the IgA antibody in the mucus even in the reproductive organs. Yeast is a microorganism that exists in human gastrointestinal tract. It is very safe and applicable as a host for the expression of recombinant proteins. Thus, using yeast as a vaccine antigen is promising. Therefore, in this study, we try to establish a yeast strain that expresses ZIKVE protein on the cell surface to use as a mucosal vaccine antigen that induces protective immunity to the genital mucosa by oral immunization.
