Avaliação do trato respiratório de equinos na microrregião centro-sul do paraná: aspectos clínicos e epidemiológicos dos achados endoscópicos e citológicos

Abstract

This work introducess that in the Guarapuava-PR microregion there are equines used in sport that present asymptomatic signs of "equine asthma syndrome", which may result in poor performance. It also shows that the HOARSI questionnaire (Lauen et al., 2010) has a correlation with the tracheal lavage cytology, with the MUCO GRADUATION described by Gerber et al. (2004) and the BREATHING SCORE reported by Robinson et al. (2000), as well as a positive result in the identification of hemosiderophages through the use of reagent tape for physicochemical analysis (urinalysis tape) (BIAVA et al., 2006). For this, 20 horses were evaluated through video-endoscopy of the respiratory tract, cytology by means of cytocentrifugation and subsequent staining by the Papanicolaou and Perls methods, and analysis of the sample shortly after collection by means of a urinalysis tape. The data generated were analyzed by the statistical program SISVAR version 5.6 (2011), submitted to analysis of variance and comparison of means (Tukey test), under importance degree of 5%. Regression equations were used to determine the correlation between the variables, being considered a correlation when R2> 70%.
