Yorkshire Farm, UK - Mike Muirhead - Final Update, June 2002
Mike Muirhead's case history of a Yorkshire farm with PMWS and PDNS.
This paper charts the course and effects of the disease on a single herd as well as highlighting the economic impact.
Photos of the clinical signs that are seen generally in pigs with PMWS and PDNS. Includes skin lesions, enlarged lymph glands, wasting and dead pigs.
Photos of the signs that are seen in post-mortem samples of pigs with PMWS and PDNS. Includes interstitial pneumonia, secondary bacterial infection, enlarged lymph nodes, oedema and intra cytoplasmic inclusions
