Antimicrobial resistance trends in blood culture positive Salmonella Paratyphi A isolates from Pondicherry, India, 2005 - 2009

摘要

Background: In the developing countries, enteric fever remains a significant problem of morbidity and mortality. S. Paratyphi A is the second most common cause of enteric fever after S. Typhi. The incidence of enteric fever caused by S. Paratyphi A has been increasing in South-East Asia, South Africa and the Indian subcontinent. Recently, there has been an upsurge in the occurrence of bacterial isolates that are resistant to ciprofloxacin, and the emergence of broad spectrum β- lactamases in typhoidal salmonellae constitutes a new challenge to the clinician.
