Shigella sonnei harboring $bla_{CTX-M-55}$ was isolated outside of Asia for the first time. The $bla_{CTX-M-55}$ gene was found to be downstream of ISEcp-1 and located in a ~130 kb conjugative plasmid belonging to the I1 incompatibility group. The strain was recovered from a 7-year-old Ecuadorian girl with watery diarrhea who had not travelled abroad. Recent local data describe the emergence of $bla_{CTX-M-55}$ and other variants typically found in Asia in the Andean Region, suggesting that increased travel of humans and trade relationships with Asian countries are influencing the current Ecuadorian bacterial resistance situation.
