Abstract
(EN) A breathable biological face covering comprising a fabric material and an anti-pathogen substance on the fabric material. The anti-pathogen substance comprises a lactoferrin protein. The amount of lactoferrin protein on the fabric material may be in the range of 0.6–1.5 grams/m2 of fabric material. Another embodiment is a lactoferrin composition comprising an aqueous fluid at pH <7.0 and lactoferrin protein mixed in the aqueous fluid at a concentration of 0.6–1.5 grams per liter. This lactoferrin composition may be administered into the respiratory tract. This composition could be useful against respiratory microbial pathogen, such as influenza virus or coronavirus.
(FR) L'invention concerne un revêtement facial biologique perméable à l'air comprenant un matériau textile et une substance anti-pathogène sur le matériau textile. La substance anti-pathogène comprend une protéine de lactoferrine. La quantité de protéine de lactoferrine sur le matériau textile peut être comprise dans la plage de 0,6 à 1,5 grammes/m2 de matériau textile. Un autre mode de réalisation fournit une composition de lactoferrine comprenant un fluide aqueux à un pH < 7,0 et une protéine de lactoferrine mélangée dans le fluide aqueux à une concentration de 0,6 à 1,5 grammes par litre. Cette composition de lactoferrine peut être administrée dans le tractus respiratoire. Ladite composition pourrait être utile contre un agent pathogène microbien respiratoire, tel que le virus de la grippe ou le coronavirus.
