Abstract |
In Denmark the detection
of MRDT104 infected herds relies on the national Salmonella
surveillance programme at farm and slaughterhouse levels of production. With
the surveillance sampling protocol and the diagnostic methods currently
available, some herds may remain undetected for a period. The number of
undetected Danish pig herds infected with multiresistant Salmonella
Typhimurium DT104 (MRDT104) in the period August 1st 2001 – July
31st 2002 was estimated and compared with the number of
culture-confirmed detected herds. A scenario tree was constructed to
illustrate where infected herds will go undetected in the surveillance system
and Monte Carlo simulation was used to model the actual number of pig herds
infected with MRDT1104. It was estimated that 52
(90% CI=[28, 178]) finisher herds were infected with MRDT104 compared to 23
(44%) detected. Among herds with
production of weaners or growers we estimated that 38 (90% CI [23, 74]) were
infected with MRDT104 compared to 7 (18%) actually detected. Among breeder
and multiplier herds it was estimated that 5 (90% CI [3, 8[) herds were
infected with MRDT104 compared to 3 (60%) detected. Running all steps of the
model together it was estimated that 102 pig herds were classified as
infected with MRDT104 in the year between August 1st, 2001 and
July 31st, 2002 (90% CI [63, 228]). In comparison, 33 (32%)
infected herds were detected in the period. |
