This prospective study reveals that 48% of 368 salmonelloses and 81% of 43 shigelloses diagnosed within one year in the Zurich area were imported from abroad. Travellers in close contact with the local population have a higher risk of being affected by typhoid fever or shigellosis than the average tourist. The clinical course was generally mild, and there was no lethal case. As the incidence of Salmonella typhi is very low, typhoid vaccination is recommended only for high-risk travellers.

Patients with inflammatory bowel disease who receive immunosuppressive therapy have an increased risk of infection. Live vaccines are contraindicated in these patients because of the increased risk of unchecked replication of the attenuated vaccine microorganisms. Vedolizumab is a gut-selective biological agent with a low risk of infection approved for the treatment of inflammatory bowel disease.

infections pose significant public health challenges worldwide. The diversity of strains, particularly those isolated from environmental and clinical sources, necessitates innovative approaches to prevention and treatment. Previous research has shown that small extracellular vesicles (sEVs) produced by macrophages during Typhimurium infection can induce robust immune responses when used as a vaccine, offering complete protection in systemic infection models.
