Multidrug-Resistant Salmonella enterica Serovar Infantis, Israel
To determine whether rapid emergence of Salmonella enterica serovar Infantis in Israel resulted from an increase in different biotypes or spread of 1 clone, we characterized 87 serovar Infantis isolates on the genotypic and phenotypic levels. The emerging strain comprised 1 genetic clone with a distinct pulsed-field gel electrophoresis profile and a common antimicrobial drug resistance pattern.

متن کاملIdentification of the plasmid-borne quinolone resistance gene qnrS in Salmonella enterica serovar Infantis.
OBJECTIVES A Salmonella enterica serovar Infantis isolate of avian origin was investigated for the presence of the gene qnrS, its transferability and its association with other resistance genes. METHODS The Salmonella Infantis isolate was investigated for its susceptibility to antimicrobial agents and its plasmid content. Hybridization experiments and PCR assays were performed to identify the...
متن کاملA novel extended-spectrum TEM-type beta-lactamase, TEM-138, from Salmonella enterica serovar Infantis.
A novel natural TEM beta-lactamase with extended-spectrum activity, TEM-138, was identified in a ceftazidime-resistant clinical isolate of Salmonella enterica serovar Infantis. Compared to TEM-1, TEM-138 contains the following mutations: E104K, N175I, and G238S. The bla(TEM-138) gene was located on a 50-kb transferable plasmid. Expression studies with Escherichia coli revealed efficient ceftazi...
متن کاملNovel haemolysins of Salmonella enterica spp. enterica serovar Gallinarum.
Haemolysins of Salmonella are important due to their probable role in pathogenesis of systemic salmonellosis and use in sub-serovar level typing. The present study was undertaken to determine haemolytic potential of Salmonella Gallinarum strains through phenotypic and genotypic methods. Amplification of haemolysin gene (clyA) and cytolysin gene (slyA) was attempted in order to determine their r...
