Enteric fever
SalmonellaTyphi causes typhoid fever whereas
Paratyphi A, B and C cause paratyphoid fever with
symptoms which are milder and a mortality rate that
is lower for the latter. Both serotypes are solely human
pathogens. Infection typically occurs due to ingestion
of food or water contaminated with human waste. In
recent years, antibiotic-resistant strains have been
isolated in most endemic areas, particularly Southeast
Asia, India, Pakistan and Middle East
