During the period 2006–2013, the top five source countries for travel-related S. Stanley infections were: Thailand (69% of all cases with known data), Pakistan (4%), India (4%), Vietnam (3%) and the Philippines (3%). The analysis of strains from the former PulseNet Europe and TESSy databases show a high genetic diversity, with no single genetic group dominating, neither temporarily nor geographically. Resistance to nalidixic acid was previously rarely reported for S. Stanley. In a study of 125 S. Stanley isolates from clinical cases in Asia and Europe in 2008, only seven (6%) strains were resistant to nalidixic acid (five of them were isolated from travel-related infections) [1]. In S. Stanley reports to TESSy between 2007 and 2013, a marked increase in the proportion of nalidixic-acid-resistant isolates was observed among cases acquired in the EU/EEA: from an annual average of 12% in 2007–2010 to 70% in 2011–2013. Meanwhile, the proportion of nalidixic-acidresistant isolates among cases acquired outside the EU/EEA remained fairly stable (average 18%, range 8–27%) over the period.
