Typing ofSalmonella entericaserovar Infantis isolates from 51 outbreaks in Germany between 1974 and 2009 by a novel phage-typing scheme

Abstract: SUMMARYWe developed a new phage-typing method and evaluated its application in combination with XbaI macrorestriction analysis by pulsed-field gel electrophoresis (PFGE) as a useful tool for the long-term epidemiology of Salmonella enterica serovar Infantis. In this study, we investigated 1008 S. Infantis isolates recovered from humans, various animal species and food products from 1973 to 2009. The typing scheme is based on 17 typing phages, defining 61 different patterns within the strain collection. The exp… Show more

“…S. Infantis isolates from stool specimens of patients, food samples, environmental samples, and animal faecal specimens were phage-typed following the standardized NRC protocol [4]. In addition, pulsed-field gel electrophoresis (PFGE) of isolates from stool specimens collected from cases living in Thuringia and Lower Saxony, animal faecal samples, food samples, and environmental samples was performed using Xba I restriction enzyme following the PulseNet CDC protocol [20].…”

“…raw or undercooked chicken, eggs, pork, and beef) have been reported [2][3][4][5][6]. Strains associated with such outbreaks have been found to circulate for periods of more than 10 years indicating a high stability of these clones [4,7]. S. Infantis can tolerate adverse physical conditions (e.g.…”

“…Δεν παρατηρήθηκαν κυρίαρχοι κλώνοι μεταξύ των στελεχών και δεν κατέστη δυνατός ο προσδιορισμός της πηγής μόλυνσης. Η χρήση της PFGE έχει χρησιμοποιηθεί από πολλούς ερευνητές για τον χαρακτηρισμό στελεχών ανθρώπινης προέλευσης ή άλλων, πολλές φορές μάλιστα και με τη χρήση συνδυαστικά και άλλων μεθόδων[230,235]. Στις μελέτες αυτές υποστηρίζεται πως δεξαμενή των κλώνων που διασπείρονται στους ανθρώπους είναι τα κοτόπουλα της βιομηχανικής πτηνοτροφίας και σπανιότερα τα βοοειδή[247] ή οι χοίροι[235].…”
