RIBEIRO, SAM et al. Incidence of Salmonella in imported day-old ducklings. Brazil, 1998-2003. Rev. Bras. Cienc. Avic. [online]. 2006, vol.8, n.1, pp.39-43. ISSN 1516-635X. http://dx.doi.org/10.1590/S1516-635X2006000100006.
The occurrence of Salmonella in a samples of 40 imported day-old duckling flocks was assessed from 1998 to 2003 according to the guidelines of the Brazilian National Poultry Health Program (Programa Nacional de Sanidade Avícola-PNSA). The pathogen was recovered from 26 flocks (65.0%). The most common serovars were S. Saintpaul and S. Kottbus. Up to four serovars were isolated from a single flock. Transportation box swabs (82.6%) and yolk sac pool (47.1%) showed the highest and the lowest frequency of Salmonella isolation, respectively. The high percentage of Salmonella isolation from imported day-old ducklings causes concern because of the zoonotic potential of this agent and its economical importance to commercial poultry breeding.
