Avaliação microbiológica e citológica do lavado traqueal de gatos hígidos.

Abstract

This study aimed to evaluate the transoral and transtracheal technique to collect the tracheal swab, besides to offer information relative the kinds of cell and microorganisms which habits in the inferior respiratory tract (IRT) of healthy cats from municipe Patos – PB in 2009, were studied 4 females, adults, with no defined breed, which participated in two techniques for collect. Were realized oral swabs, aiming to offer information about the bacteria in the oropharingeal tract and to compare with the microbiological data. The animals were anesthetized to collect the samples and when the technique used was the transoral, the animals were intubated. It was evaluated the level of cellular and bacterial contamination, and in the transoral technique was observed microorganisms compatible to that found in the oral swab and with that which common the oral cavity. It was not observed fungi development and the bacteria isolation occurred in all the samples collected by the transoral technique, and in 75% of the samples collected by the transtracheal technique. In 87,5% of the samples, were isolated two or more microorganisms. It was isolated Pasteurella sp. and Bordetella sp., related in the literature as microorganisms involved in IRT diseases of cats, besides Alloicoccus sp. descript only in the human literature. In the cytology, was possible to verify the macrophages and neutrophil predominance in the both groups. The epithelial cheratinizated cells were the most found in laminas from the transoral technique. It could be observed in smaller number: lymphocytes, plasmocytes, cubic epithelial cells, ciliated cylindrical epithelial cells, pavement and globular cells. The both techniques demonstrated to be safety, therefore the transtracheal show to be the most adequate due the decrease in the contamination by the oral cavity microorganisms.
