| Affected population |
5 nasal swabs gave positive result for RNA using PCR real-time technique.One sample taken from allantoic fluid of a foal resulted RNA positive. The amplification of this latter sample related to NA gene gave the following result:sequence identity of 100% and query cover 84% corresponding to :A/Equus caballus/Pas-de-Calais/2018, H3N8 Florida Clade 1 | |
