Enterobacteriaceae co-producing NDM- and OXA-48-type carbapenemases were encountered in higher frequency in the United Arab Emirates (UAE) than in the neighboring countries in our earlier study. The aim of this investigation was to characterize the seven double carbapenemase producer Klebsiella pneumoniae found in the region to assess factors contributing to their emergence. Three K. pneumoniae ST14 isolated in the UAE harboring blaNDM-1 on IncHI1b and blaOXA-232 on IncColE plasmids were clonally related. Furthermore, two K. pneumoniae from the UAE, ABC106 and ABC137 belonged to ST307 and ST1318, respectively. ABC106 carried blaNDM-1 on IncHI1b, and blaOXA-162 on IncL/M plasmids, whereas ABC137 possessed blaNDM-1 on IncX3 and blaOXA-48 on IncL/M plasmids. The double carbapenemase-producing K. pneumoniae from Oman (OMABC109) and Saudi Arabia (SA54) belonged to ST11 and ST152, respectively. OMABC109 harbored blaNDM-1 on an IncHI1b plasmid highly similar to the NDM-plasmid of ABC106 and carried a chromosomally coded blaOXA-181 located on Tn2013. SA54 possessed a blaNDM-1 on an IncFIb/FII plasmid and a blaOXA-48 on an IncL/M plasmid. Based on these findings, clonal spread and horizontal transfer of carbapenemase genes located on transposons or self-transmissible plasmids contributed equally to the emergence of double carbapenemase-producing Enterobacteriaceae in the region.

D009850 Oman A sultanate on the southeast coast of the Arabian peninsula. Its capital is Masqat. Before the 16th century it was ruled by independent emirs but was captured and controlled by the Portuguese 1508-1648. In 1741 it was recovered by a descendent of Yemen's imam. After its decline in the 19th century, it became virtually a political and economic dependency within the British Government of India, retaining close ties with Great Britain by treaty from 1939 to 1970 when it achieved autonomy. The name was recorded by Pliny in the 1st century A.D. as Omana, said to be derived from the founder of the state, Oman ben Ibrahim al-Khalil.

D014479 United Arab Emirates A federation of seven states on the southeast portion of the Arabian peninsula: Abu Dhabi, Ajman, Dubai, Fujairah, Ras al-Khaimah, Sharjah and Umm al-Qaiwain. In 1820 a treaty of peace was concluded between Great Britain and native rulers. During the 19th century the rulers agreed to suppression of the slave trade and restriction of foreign relations to Great Britain. The Trucial Council was established in 1952 and defense treaties with Great Britain terminated. In 1971 an independent six-member federation was formed, with Ras al-Khaimah joining the federation in 1972. (From Webster's New Geographical Dictionary, 1988, p1250) Abu Dhabi,Trucial States
