Assessing Salmonella Typhi Pathogenicity and Prevention: The Crucial Role of Vaccination in Combating Typhoid Fever

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(9), P. 3981 - 3981

Published: April 23, 2025

Enteric fever is caused by Salmonella enterica serovar Typhi (S. Typhi) and Paratyphi Paratyphi) A, B, C. Globally, an estimated 11 to 21 million cases of typhoid paratyphoid occur annually, with approximately 130,000–160,000 deaths, most which are reported in South/Southeast Asia sub-Saharan Africa. The antibiotic susceptibility S. strains varies between countries within broad limits, from 3% 97% for ampicillin, 9% 95% ciprofloxacin, 4% 94% chloramphenicol (India vs. Pakistan), 0% 99% ceftriaxone Iraq). With increasingly exhibiting resistance antibiotics, vaccination becomes essential preventive measure. Currently, three vaccines licensed fever: the conjugate vaccine (TCV), live-attenuated oral Ty21a (Ty21a), Vi capsular polysaccharide (Vi-CPS). While no specific exists fever, genetic antigenic similarities offer potential development such a vaccine. Early studies show promising results, demonstrating both safety immunogenicity preclinical trials. Whole genome sequencing (WGS) provides powerful tool assigning genotypes, identifying plasmids, comparing elements, investigating molecular factors that contribute virulence.

Salmonellosis in dairy cattle represents an increasing problem for both animal and public health. Nevertheless, Italy, there is no control plan place on farms. The aim of this study was to describe a Salmonella Bredeney outbreak that occurred farm the measures were adopted outbreak. Management consisted identifying spread infection assessing environmental contamination spp. associated risk factors. After visit, laboratory investigations showed 48% rectal swabs collected from calves 33% samples positive S. Bredeney, poor biosecurity level detected. farmer practitioner provided with health management spp., followed by monitoring period follow-up visit which all resulted negative. results demonstrated efficacy indirect prophylaxis reducing circulation leading extinction Collaboration farmers, practitioners, veterinarians introduction reported constitute possible model outbreaks herds, even complex situations.
