Une \u00e9quipe internationale compos\u00e9e de chercheurs de l’Institut de Virologie et d’Immunologie (IVI<\/a>) de l’Office f\u00e9d\u00e9ral de la s\u00e9curit\u00e9 alimentaire et v\u00e9t\u00e9rinaire BLV et de l’Universit\u00e9 de Berne<\/a>, du Centers for Disease Control and Prevention (\u00c9tats-Unis) et de l’Institut Friedrich-Loeffler (Allemagne) a mis au point une approche permettant d’\u00e9valuer avec pr\u00e9cision la transmissibilit\u00e9 des nouvelles souches mutantes de virus.<\/p>\n

Cette nouvelle approche peut \u00eatre utilis\u00e9e pour tester une seule mutation ou une combinaison sp\u00e9cifique de mutations qui sont pr\u00e9sentes dans un certain nombre de variantes virales actuellement en circulation. L’IVI s’appuie sur une technique de clonage mise au point \u00e0 Berne il y a un an<\/a>, qui permet de reproduire exactement les virus du SARS-CoV-2 en laboratoire. Le virus britannique, par exemple, est connu pour avoir non pas une mais souvent plus de 14 mutations, dont huit se produisent dans la prot\u00e9ine de spicule.<\/p>\n

Ainsi, \u00e0 l’aide de la technique de clonage, un nombre illimit\u00e9 de mutations de variantes peuvent \u00eatre reproduites et utilis\u00e9es pour entrer en concurrence les unes avec les autres dans des cultures cellulaires et des \u00e9chantillons animaliers. Les r\u00e9sultats montrent comment des mutations uniques affectent la capacit\u00e9 de transmissibilit\u00e9 des nouveaux variants.<\/p>\n

Des projets de recherche similaires sur les agents pathog\u00e8nes infectieux pourraient \u00e9galement \u00eatre men\u00e9s \u00e0 l’avenir au Centre Multidisciplinaire des Maladies Infectieuses et de l’Immunit\u00e9 (MCIDI<\/a>) nouvellement cr\u00e9\u00e9 \u00e0 l’Universit\u00e9 de Berne. Actuellement, l’IVI est le seul laboratoire de haute s\u00e9curit\u00e9 en Suisse o\u00f9 des maladies animales hautement contagieuses (comme la fi\u00e8vre aphteuse ou la fi\u00e8vre porcine) peuvent \u00eatre diagnostiqu\u00e9es et \u00e9tudi\u00e9es.<\/p>\n","protected":false},"excerpt":{"rendered":"
