Abscess - Atlas of swine pathology
Where: skin and subcutaneous tissue
Possible causes: Other
Abscesses are pockets of pus that contain dead cell material and large numbers of bacteria. The bacteria normally enter the body through damage to the skin or via the external orifices. Near the skin surface they may become painful with an inflamed appearance. In this case, the abscess was caused by the use of dirty needles when vaccinating sows due to a change of management.
