HISTOPATHOLOGICAL CHANGES OF THE LYMPHOID TISSUES IN POSTWEANING MULTISYSTEMIC WASTING SYNDROME (PMWS) AFFECTED PIGS
Abstract
Postweaning multisystemic wasting syndrome, caused by porcine circovirus type 2 (PCV2), is a recently described clinical condition which affects nursery and growing pigs (Segales and Domingo, 2002). PMWS was initially recognized in Canada in 1991 and nowadays is considered to be worldwide distributed. Macroscopic lesions associated with PMWS are quite unspecific, but histopathological lesions in lymphoid tissues (lymphocyte depletion with histiocytic infiltration) are almost unique for this disease (Allan, 2000; Harding, 1996).a) Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a Creative Commons Attribution License that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.
