Adding an aqueous iodine supplement to nursery pigs, therefore, did not provide an advantage for either growth or oral condition. Deleterious oral conditions do increase after weaning, with gingivitis being associated with lower piglet weight.

A herd-based survey of Salmonella in pigs was carried in a major pig producing region of Spain. Mesenteric lymph nodes were collected from the carcasses of 25 pigs from each of 80 herds at time of slaughter.

The results indicate that administration of a Salmonella choleraesuis-attenuated vaccine on the first day of life decreases Salmonella isolation and seroprevalence in pigs at slaughter.

Experimental infection of Salmonella enterica ssp. enterica serovars Panama was proceeded to establish the importance of nose-to-nose contact in the transmission among weaned pigs.

The primary objective of this 7-month study was to determine the prevalence of porcine pathogens of the tonsil of the soft palate, principle tonsil of the pig, of swine at slaughter.

Consumption of diets containing seaweed-derived extracts does not diminish faecal shedding of Salmonella in post-weaned piglets.

The objectives of this field survey were to evaluate the effects of several promising swine waste-management and treatment technologies on reducing Salmonella presence and populations and to characterize the diversity of Salmonella isolates recovered from the waste streams using serotyping and antibiotic-susceptibility analysis.

Lactobacillus plantarum, microencapsulated organic acids or fermented soybean meal may be taken into account as antimicrobial alternatives for piglet diets.

Salmonella enterica subsp. enterica serovar Typhimurium was isolated from diarrheic piglets in 2 periods, 2000–2001 (n = 25) and 2005–2006 (n = 17). To compare the characteristics of the isolates collected during the 2 periods, all isolates were tested for antimicrobial resistance, the presence of virulence genes, and pulsed-field gel electrophoresis (PFGE) patterns.

A cross-sectional study was conducted in Spain to estimate the prevalence of Salmonella enterica in feed mills and to identify and evaluate potential risk factors associated with feed contamination.

The purpose of this study was to determine the occurrence and genotypic relatedness of Salmonella enterica isolates recovered from feed and fecal samples in commercial swine production units.

Hulless barley in piglet diets may reduce Salmonella typhimurium transmission among penmates.

The objective of this study was to assess in pigs the pathogenicity and virulence of 3 strains of Salmonella spp capable of causing atypical salmonellosis in cattle.

Feed-borne spread of Salmonella spp. to pigs has been documented several times in recent years in Sweden. Experiences from the field suggest that feed-associated serotypes might be less transmittable and subsequently easier to eradicate from pig herds than other serotypes more commonly associated to pigs.

A marked increase in the prevalence of S. enterica serovar 4,[5],12:i:- with resistance to ampicillin, streptomycin, sulphonamides and tetracyclines (R-type ASSuT) has been noted in food-borne infections and in pigs/pig meat in several European countries in the last ten years.

The best sensitivities and specificities, with the serum as reference, were obtained with the sterno‐mastoid muscle sampled at the end of the slaughter chain and analysed after 1 month of freezing.
