Description | 呼吸器病罹患子牛からの細菌学的検査用サンプル採取のために,鼻腔より非目視下(ブラインド法)または簡易内視鏡を用いた目視下(内視鏡法)にて気管深部洗浄液(tracheal wash fluid:TWF)を回収する手法について検討した。TWF回収では栄養カテーテルが他器具と比較し回収成功率が高く,栄養カテーテルを用いたTWF回収率(回収量/注入量)はブラインド法と内視鏡法で同等(39%,32%)であった。細菌学的検査では,鼻腔スワブとTWFを同時に採取した11頭中4頭で細菌種が一致し,また,20頭中14頭でTWFから主要な肺炎原因菌が分離された。本試験で試行したTWFによる細菌学的検査用サンプルの採取は,臨床現場における検査方法のひとつとして有用であることが示唆された。

Description Alternative | A comparison was made between methods with or without visualization (i.e., blind and endoscopic methods) for collection of tracheal wash fluid (TWF) from calves with respiratory disease. In both endoscopic and blind methods, the success rate of collecting TWF was higher with a feeding catheter than other catheters, and the recovery rate of TWF was similar between the blind and endoscopic methods (39% and 32%, respectively). In a bacteriological examination, it is only in 4 of the 11 calves that the same bacterial species were collected in deep nasal swab samples and TWF samples taken at the same time. The major pneumonia-causing pathogens were isolated from TWF samples in 14 of the 20 calves. These results suggested that the TWF collection tried in this study was useful for bacteriological examination in the clinical settings.
