Salmonella was isolated from rectal swabs of free-ranging and stranded grey seal pups (21.1{\%}; 37/175) and compared to strains from the same serovars isolated from human clinical cases, livestock, wild mammals and birds in Scotland, UK to characterise possible transmission routes using pulsed-field gel electrophoresis (PFGE) and multi-locus variable number of tandem repeat (MLVA) analyses. A higher prevalence of Salmonella was found in pups exposed to sea-water, suggesting that this may represent a source of this pathogen.

Salmonella Typhimurium was infrequent (2.3{\%} pups; 4/175), mostly similar to isolates found in garden birds and, in one case, identical to a highly multidrug resistant strain isolated from a human child. Salmonella Haifa was rare (1.1{\%} pups; 2/175) but isolates were indistinguishable from that of a human clinical isolate. These results suggest that S.
