PMWS and PDNS in the UK
UK - Veterinary Laboratories Agency (VLA) Quarterly Surveillance report on PMWS and PDNS from April - June 2004
Diagnoses of PMWS, as a percentage of
diagnostic submissions, remained high at
16.7%. Though down on the same
quarter in the previous three years this
was only significant statistically when
compared with 2002 (29.6%).
Nevertheless there are reports of a
decline in the clinical importance of
PMWS in many herds in England, though
porcine circovirus type 2 (PCV-2) was still
mentioned in a quarter of all Regional
Laboratory incident reports on pigs.
PCV-2 infection is therefore recognised in
a significant proportion of diagnostic
submissions. Associated diseases are
not limited to commercial breeds as
PMWS was again diagnosed in
Gloucester Old Spot piglets. On some
units high mortality due to PMWS is still occurring with one farm reporting a
postweaning mortality of 15 percent.
There were six incident reports of PDNS
of which two were sporadic cases at the
time of investigation and four were
outbreaks. In one outbreak 50 ten-weekold
pigs were affected, in a second
outbreak 130 of 650 were affected, and
in a third outbreak 150 ten-week-old pigs
were affected with 50 dead.
