Doença inflamatória das vias aéreas (DIVA) em eqüinos de policiamento: estudo clínico

Abstract

The objective of this study was the clinical characterization of Inflammatory Airway Disease (IAD) in apparently healthy horses from the police force. Seventeen adult horses, 11 to 24 years old, of both genders, were used. The control group was formed by8 animals, and the experimental group, by nine. Leukograms and plasma fibrinogen concentration were inside the normal range in all animals. The control group was formed by animals showing mean nucleated cell differential counts in theirbronchoalvelar lavage (BAL) inside the normal range, according to MCGorum et al. (1993). The experimental group, according to Hoffman (2003), was characterized by neutrophil (>5% and <25%) and eosinophil (>1%) infiltrates. Horses were submittedto physical and endoscopic examinations, as well as measurement of maximum intrapleural pressure. Although results were in the normal range for the species, the analysis of vital functions and the difference in maximum intrapleural pressure showedsignificant differences only for body temperature and heart rates. No significant difference was observed between the two groups in the physical examination of the respiratory tract. Based on the results, IAD in animals from the police force showeddiscrete clinical signs, and the disease may be considered quiescent. UR - http://pesquisa.bvsalud.org/ghl/resource/en/lil-521218
