Protocollo diagnostico applicabile in allevamenti di cavalli con anamnesi di adenite

The Authors describe a diagnostic approach used in a horse breeding where recurrent upper respiratory infections strangles-like occur. Nasopharyngeal swabs and guttural pouches lavages for citological and bacteriological assessement have been performed. No empyemas or chondroids were evident in guttural pouches and no Streptococcus equi has been isolated. For these reasons it’s possible to assert that no asymptomatic carriers were present in the breeding and endemic infection can be excluded. More investigations will be necessaries in order to verify the possible involvment of others Streptococcus species in the genesis of that kind of disease.
