Abstract

Due to the high morbidity and mortality of respiratory tract diseases presented by cetaceans1,2 and to a difficult etiological diagnosis, videoendoscopy represents the golden standard as a current diagnosis technique in marine mammal medicine2, 5,6 and in particular of bottlenose dolphins (T. truncatus) and is an important resource for obtaining samples in cytopathological studies, cultures and isolation of microorganisms which allow, in most cases, a diagnosis to be determined as well as the stage of the disease1,2,3,4,5.

The great advantage of being a direct visual method of minimal invasion, is that it´s carried out under the patient's tranquilization and containment in a short and safe time, the information obtained is very relevant.2,5,6. The endoscopic study should always be complementary to radiographic and CT studies.

The purpose of this paper is to describe the elemental airway injuries observed during follow-up of different endoscopic procedures of this case of chronic pneumonia and describing the different isolated etiological agents1,3,4 in each follow-up of an 8-year-old male T. truncatus, as well as measures and treatments followed to improve the patient's condition.
