Abstract: ABSTRACT The objective was performed to analyze clinical, hematological, and microbiological profiles through culture of secretions obtained by tracheal lavage in horses with respiratory infections. The study involved 19 male and female horses aged between 3 months and 10 years presenting signs of respiratory disease. They underwent anamnesis, clinical examination, and laboratory tests. For tracheal lavage, sedation with 10% xylazine (1.1mg/kg intravenously) was performed, followed by trichotomy on the ventral edge of the mid-distal region of the neck, anesthetic button using 2% lidocaine without a vasoconstrictor, and surgical antisepsis. The trachea was accessed using 14G catheter, through which n.4 urethral probe was introduced and attached to 20mL syringe containing lactated Ringer’s solution. Immediately the solution was aspirated along with the tracheal secretion. The samples were refrigerated and transported to the laboratory in isothermal boxes for microbiological culture. The microbiological culture the following pathogens were identified: Rhodococcus in 8/19 (42.1%), Aspergillus in 6/19 (31.6%), and Klebsiella, Streptococcus, and Escherichia coli/Proteus in 1/19 (5.3%) each; 2/19 (10.5%) samples were negative. The tracheal lavage is an effective method for collecting tracheal secretions and the association of clinical and laboratory tests provide rapid, early, and conclusive diagnosis in animals with suspected pulmonary disease.
