Unfortunately, the original version of this article [1] contained errors. The additional files were displayed in the wrong order and also duplicated where video 6 was identical to video 4 and video 7 was identical to video 5. The video files have been included here in the correct sequence.

Additional files 3, 4, 5, 6, 7, 8 and 9 have been included to further illustrate adult cattle with chronic suppurative pneumonia. Each video file has its own caption which gives more detail.
