Abstract :
[en] Salmonella species infections of male mule ducks were studied for 32 months in 100 flocks
on nine duck farms in Belgium. The prevalence of Salmonella species infections changed
significantly over time (P<0.001) with infection rates of 50, 13.4, 6.7, 2.6 and 2.9 per cent,
respectively, at the time of arrival on the farm, at three, six and nine weeks of age, and
when the ducks left the breeding unit to enter the force-feeding rooms (at 11 or 12 weeks
of age). During the study period, 95 strains of Salmonella were isolated, belonging to 11
serotypes. S Indiana (42.1 per cent) and S Regent (36.8 per cent) were the two most common
serotypes, whereas S Typhimurium and S Enteritidis were found only once (1.1 per cent). All
isolated strains were resistant to at least two antimicrobials, but resistance to more than five
antimicrobials was observed in 21.6 per cent of the strains.
