The incidence of invasive salmonellosis has increased among children and HIV-infected adults in Malawi. This has been associated with the emergence of drug resistance in the non-typhoidal Salmonella serovars Enteritidis and Typhimurium. In contrast, S. Typhi isolates have remained fully sensitive to commonly used antibiotics and the estimated incidence of typhoid fever, although still present, ...

Salmonella enterica (S. enterica) are Gram-negative bacteria that can invade a broad range of hosts causing both acute and chronic infections. This phenotype is related to its ability to replicate and persist within non-phagocytic host epithelial cells as well as phagocytic dendritic cells and macrophages of the innate immune system. Infection with S. enterica manifests itself through a broad r...

BACKGROUND Although chronic infections by typhoidal Salmonella are well-known, prolonged human infections by nontyphoidal Salmonella (NTS) are poorly characterized. METHODS We retrospectively analyzed 48 345 culture-confirmed NTS infections that occurred in Israel 1995-2012. A case-control study was performed to identify risk factors associated with persistent infections. Whole-genome-sequenc...

Introduction. Acalculous cholecystitis in the setting of typhoid fever in adults is an infrequent clinical encounter, reported sparsely in the literature. In this case report we review the presentation and management of enteric fever involving the biliary system and consider the literature surrounding this topic. The aim of this case report is to alert clinicians to the potential diagnosis of e...

The present study was conducted to know the prevalence of Salmonella and E.coli serovars in pigs at different localities of Andhra Pradesh as non typhoidal Salmonella strains and E.coli are important causes of reportable food borne infection. Among 101 faecal samples screened six isolates of Salmonella ie. S. derby (3) , S.typhimurium (2) and S.typhisuis (1) and twenty isolates of E.coli viz. 0...

INTRODUCTION Non-typhoidal Salmonella is considered one of the leading causes of foodborne disease worldwide. This protocol provides methods that will be used to synthesise available epidemiological data on non-typhoidal enteric Salmonella in humans and food in Middle East and North Africa (MENA) region and to characterise the morbidity of human salmonellosis in this region. METHODS AND ANALY...
