Salmonella enterica serotype Kentucky associated with human infections in Switzerland: Genotype and resistance trends 2004–2009

Quinolone Resistance Mechanisms in Salmonella enterica Serovars Hadar, Kentucky, Virchow, Schwarzengrund, and 4,5,12:i:−, Isolated from Humans in Switzerland, and Identification of a Novel qnrD Variant, qnrD2 , in S . Hadar

“…Only isolates containing the substitution Ser80¡Ile in ParC, i.e., 15 S. Kentucky isolates and one S. Hadar isolate (N10-1465) were resistant to ciprofloxacin according to CLSI criteria (18). As no mutations in parC were detected in S. Virchow, S. Schwarzengrund, or S. enterica serovar 4,5,12:i:Ϫ, this finding indicates that topoisomerase IV mutations are possibly characteristic of S. Kentucky and may occur more frequently than previously understood (19), although it may be due to the fact that most of the isolates belong to the same large cluster (9).…”

“…All the ciprofloxacin-resistant S. Kentucky isolates contained the substitution Ser83¡Phe in GyrA, and six isolates e Isolates belonging to a large cluster (9). f Isolates associated with travel to Thailand (10).…”

Prevalence, Detection and Antimicrobial Resistance Pattern of Salmonella in Sudan

“…The ranking of this serovar among other serovars increased substantially during the past decade in most European countries Gill and Threlfall, 2007;Bonalli et al, 2011). However, this serovar was considered an unsuccessful pathogen because it was rarely associated with human illness (Collard et al, 2007).…”

“…The S. Kentucky serovar, which has a lesser potential for infection, was common to human, chicken and food items. Furthermore, S. Kentucky isolates are known for their resistance to ciprofloxacin, the antibiotic of choice for the treatment of typhoid in Sudan (Bonalli et al, 2011). Thus this phenotype may spread to other serovars which might have greater potential for infection.…”

Introduction to the Special Issue: Salmonella in foods: Evolution, strategies and challenges

“…Eight articles report on the prevalence of Salmonella in food producing animals or foods in several countries around the world (Arguello et al, 2012;Bonke et al, 2012;Bouzidi et al, 2012;Chinivasagam et al, 2012;Kuijpers et al, 2012;Mannion et al, 2012;Rostagno et al, 2012;Vieira-Pinto et al, 2012). A total of fourteen articles focus on antibiotic-related issues of Salmonella isolated from foods, food producing animals, food-related environments or from humans (Adzitey et al, 2012;Bonalli et al, 2012;Boxstael et al, 2012;Chen et al, 2012a, b;Habing et al, 2012;Han et al, 2012;Louden et al, 2012;Marrero-Ortiz et al, 2012;Oliveira et al, 2011b;Turki et al, 2012a, b;Wasyl et al, 2012;Yang et al, 2012).…”
