The survey covered the time period from 2014 to 2019 and targeted aMPV
subtype B detected during routine diagnostic activity performed in Italy
by the Universities of Bologna and Padua or in Spain by the Centre de
Sanitat Avícola de Catalunya i Aragó (CESAC).
Samples originated from different European countries and were usually
collected during outbreaks of respiratory disorders referable to aMPV
infections in turkey, chicken or guinea fowl flocks. Sampling was also
performed for epidemiological purposes in absence of clear clinical
signs.
As a rule, samples consisted of pools of 10 rhino-pharyngeal swabs per
