Abstract
BackgroundThus far, studies on Klebsiella pneumoniae carbapenemase (KPC)-producing organisms have only been reported in those with a history of foreign travel, and a specific Japanese KPC-producing isolate has not yet been reported.Case presentationWe describe a Japanese patient, with no history of travel to foreign countries, admitted due to aspiration pneumonia, and a KPC-producing isolate detected in his sputum. Fortunately, his pneumonia resolved. His close contacts did not have a history of foreign travel, and the isolate was not detected in other patients.ConclusionsThe potential for KPC-producing organisms to become endemic in Japan is currently of great concern.

Far, studies on Klebsiella pneumoniae carbapenemase (KPC)-producing organisms have only been reported in those with a history of foreign travel, and a specific Japanese KPC-producing isolate has not yet been reported
We report a Japanese patient without a history of travel to foreign countries whose sputum samples tested positive for a KPC producing isolate
Discussions and conclusions To our knowledge, this case showed the first possibility of a new threat in Japan regarding a KPC-producing isolate not linked with a history of travelling to other countries
