Emergence of an SGI1-bearing salmonella enterica serotype kentucky isolated from septic poultry in Nigeria

Abstract

Introduction: Salmonella enterica serotype Kentucky was isolated from septic poultry in Nigeria. The objective of this study was to characterize this isolate by screening for SGI1 and hyper-virulence. Methodology: The strain was characterized by identification of Salmonella genomic island 1 (SGI1) through a PCR assay and we used a tissue culture invasion assay to assess protozoa-mediated hyper-invasion. Results: Salmonella genomic island 1 (SGI1) was identified in the strain along with an GI1 gene (SO13) implicated in hyper-virulence. Protozoa-mediated hyper-invasiveness was also documented in the strain. Conclusion: The hyper-invasion is concordant with this emerging strain's ability to cause fowl paratyphoid. © 2012 Ogunleye and Carlson.
