Resumen
The presence of Salmonella was studied by the ISO 6579:2002/Amd 1:2007, in mesenteric lymph nodes of a representative population of Navarra’s sows (i.e. 239 sows from 13 farms, representing 58% of the total sow census and 81% of farms with more than 1,200 sows/farm). As result, 6.7% of animals were found infected, in 6/13 (46.1%) of farms analysed, showing most of these farms around an 11% of prevalence. About half (7/16) of the strains isolated were S. Typhimurium phage-type DT104B, DT195 or DT193, showing multiple antimicrobial resistance (AR) patterns. Serotype Enteritidis, mainly associated to poultry, was found in the 12.5% of the infected sows. The 56.6% of strains showed AR to, at least, 5 agents, being the classical A-C-S-Su-T family AR profile the most frequently found. Also, the seroprevalence was determined by a commercial ELISA test, showing that 100% of farms and 95.2%-41% of sows, according to the cut-off adopted, were positive to salmonellosis. This result wide disagrees with the bacteriological findings, suggesting a limited value of serological tests for in vivo monitorization of sow salmonellosis.
