Experimental study of possible interaction between Salmonella enterica and Ascaris suum in pigs

An experimental inoculation study was performed to study possible interactions between Salmonella enterica and Ascaris suum in pigs. Pigs were inoculated with 109 cfu Salmonella Typhimurium, 10,000 infective A. suum eggs, or both, or left as uninfected controls. There was no significant difference in number of Salmonella-excreting animals or Salmonella excretion level in feces between pigs inoculated with Salmonella + Ascaris and pigs inoculated with Salmonella only. Occurrence of Salmonella in liver, lungs, intestines or intestinal lymph nodes was not different between these two groups either

The aim of this study has been to investigate the possible interaction between infections with Salmonella enterica serovar Typhimurium (S. Typhimurium) and Oesophagostomum spp. In an experimental set-up, groups of 10 pigs were infected with A) a mixture of O. dentatum and O. quadrispinulatum; B) O. dentatum, O. quadrispinulatum and S. Typhimurium, and C) S. Typhimurium only. Our study suggests that Oesophagostomum spp. infection in pigs provides the basis for a prolonged and intensified S. Typhimurium infection. Both levels and number of S. Typhimurium excreting pigs per day were significantly higher in the group with both Oesophagostomum spp. and S. Typhimurium infection compared to the group infected with S. Typhimurium only. Post mortem examinations paralleled these findings and demonstrated higher occurrence ofS. Typhimurium in pigs with concurrent parasite infection compared to pigs infected with S. Typhimurium only. An effect of the S. Typhimurium infection on the Oesophagostomum infection was not observed
