Salmonella enterica serovar typhi (S. typhi) and paratyphi are subtypes of the gram negative enteric pathogen Salmonella enterica that causes enteric fever. These pathogens are human restricted and are a significant cause of morbidity and mortality in low and middle income countries (LMICs). According to Stanway et al. (2019), 14ยท3 million cases of typhoid and paratyphoid fever infection and more than 135,000 deaths due to this infection occurred globally in 2017. Though this is significantly lower than 26 million culture positive infections recorded in 2010 (Buckle et al., 2012), enteric fever still remains a major health burden with billions of people likely to be exposed to the pathogen. Transmission is mainly through the faeco-oral route through consumption of materials contaminated with fecal material.
