Usutu virus (USUV) sequences from mosquitoes (Culex pipiens s.l.) cluster with sequences of isolates from wild birds in England. Bayesian phylogenetic analysis of USUV sequence data (approximately 5Â kb) retrieved from an adult mosquito pool as well as two adults reared from larva in 2023. The sequences were aligned with 15 USUV Africa lineage isolates from across mainland Europe. Node labels represent posterior probabilities and accession numbers are shown.
