Therefore, an outbreak management team was installed, by whom a contact tracing plan was made. In addition to general outbreak measures, specific measures were formulated to allow continuation of the rehabilitation process. Also, environmental cultures were taken. Multiple-locus variable-number tandem-repeat analysis and amplification fragment-length polymorphism were used to determine strain relatedness. Selected isolates were subjected to whole-genome multilocus sequence typing.<\/jats:p><\/jats:sec><jats:sec id=\"S0899823X19003040_as5\"><jats:title>Results:<\/jats:title><jats:p>The outbreak lasted 8 weeks. In total, 14 patients were colonized with an ESBL-<jats:italic>K. pneumoniae<\/jats:italic>, of whom 11 patients had an isolate belonging to sequence type 307. Overall, 163 environmental cultures were taken. Several sites of a household washing machine were repeatedly found to be contaminated with the outbreak strain. This machine was used to wash lifting slings and patient clothing contaminated with feces. The outbreak was contained after taking the machine temporarily out of service and implementing a reinforced and adapted protocol on the use of this machine.<\/jats:p><\/jats:sec><jats:sec id=\"S0899823X19003040_as6\"><jats:title>Conclusion:<\/jats:title><jats:p>We conclude that in this outbreak, the route of transmission of the outbreak strain via the household washing machine played a major role.<\/jats:p><\/jats:sec>","DOI":"10.1017\/ice.2019.304","type":"journal-article","created":{"date-parts":[[2019,11,5]],"date-time":"2019-11-05T07:31:46Z","timestamp":1572939106000},"page":"31-36","source":"Crossref","is-referenced-by-count":33,"title":["An outbreak of ST307 extended-spectrum beta-lactamase (ESBL)\u2013producing<i>Klebsiella pneumoniae<\/i>in a rehabilitation center: An unusual source and route of transmission"],"prefix":"10.1017","volume":"41","author":[{"given":"Marrit B.","family":"Boonstra","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dorien C.
