Current situation of carbapenem‐resistant Enterobacteriaceae and Acinetobacter in Japan and Southeast Asia.

SOUTHEAST Asia; JAPAN

In the recent years, issues related to drug‐resistant bacteria have evolved worldwide, and various countermeasures have been taken to control their spread. Among a wide variety of drug‐resistant bacterial species, carbapenem‐resistant Gram‐negative bacteria, including carbapenem‐resistant Enterobacteriaceae (CRE) and carbapenem‐resistant Acinetobacter baumannii (CRAb), are those for which countermeasures are particularly important. Carbapenems are the last resort antibiotics for any bacterial infection; therefore, infectious diseases caused by these drug‐resistant bacteria are difficult to treat. In the case of CRE, since carbapenemases responsible for carbapenem resistance are mostly encoded on transmissible plasmids, it is known that susceptible bacteria can easily become carbapenem‐resistant by transfer of plasmids between Enterobacteriaceae. In addition, Enterobacteriaceae are common bacterial species found in the guts of animals, including humans. Acinetobacter is ubiquitously isolated in the environment. Due to these characteristics, it is quite difficult to prevent the intrusion of multi‐drug resistant pathogens in hospitals. Therefore, effective countermeasures should be developed and utilized against such dangerous pathogens based on molecular epidemiological analyses. In this review, there are also some examples presented on how to manage to monitor and control those troublesome drug‐resistant bacteria conducted in Japan and Southeast Asia. [ABSTRACT FROM AUTHOR]
