摘要: Tigecycline and carbapenem are last-resort antibiotics for serious infections caused by pathogens with multi-drug resistance (MDR). Whereas, bacterial pathogens with co-resistance to tigecycline and carbapenem are poorly addressed. Here we report a tigecycline- and carbapenem-resistant Acinetobacter indicus strain HY20 of duck origin, which co-produces Tet(X5) and NDM-3. Tet(X5) is harbored by a novel plasmid pAI01 (116,992 bp long), which carries 10 antimicrobial resistance genes (AMRs), and heavy metal resistance system cobalt-zinc-cadmium (czc) gene cluster. Unlike that tet(X5) is located in the res tet(X5) xerD segment of plasmid, the chromosomal bla(NDM-3) is flanked by insertion ISAba125. Collectively, our result represents an example of co-carriage of tet(X5) and bla(NDM-3), heightening the importance of AMR surveillance needed in poultry production.
