Emergence of Salmonella paratyphi A as a major cause of enteric fever: need for early detection, preventive measures, and effective vaccines.

摘要

Enteric fever (EF) is a systemic infection caused by Salmonella enterica serotype typhi (typhoid fever) or serotypeparatyphi A, B, or C (paratyphoid fever). However, other organisms may also cause the EF syndrome.' EF used to be an important cause of morbidity and death in war-torn and developing countries including Thailand. However, improved sanitation has reduced the prevalence of EF worldwide. It nevertheless remains a serious public health problem in parts of Asia where sanitary conditions remain poor.
