PMWS and PDNS latest news August 2003
UK - Veterinary Laboratories Agency (VLA) Quarterly Surveillance report on PMWS and PDNS from April to June 2003
Following on from the comments in the
previous Quarterly Surveillance Report,
VLA Bury St Edmunds reported that
several practitioners in their region had
noted a marked increase in PMWS
(increased wasting and mortality) in
growing pigs on units where mortality had
previously been controlled by the 20-point
Madec Plan.
PMWS was confirmed on the basis of
gross lesions, histopathological changes,
and IHC for PCV-2 in a 4-month-old
purebred farmed wildboar. The pig came
from a 110-sow commercial outdoor unit
with a problem of illthrift in piglets from
around three months of age ? weaning
age is variable from three to five months
of age.
PMWS was confirmed in two 9-week-old
pigs, which were anaemic, wasting, and
scouring, and had developed pendulous
abdomens. PMWS had previously been
diagnosed on the unit where it presented
as respiratory disease.
